5 What is Zenium What is Zenium Zenium is a flexible platform for workflow design, deployment & management. Zenium consists of: Zenium Designer: A graphical tool used to design and test graphs and blueprints. Zenium Framework: The core Zenium graph execution libraries. That is, the underlying application that is used to connect and manage components, and to run graphs and blueprints. Zenium Repository: A centralized pool of component technologies and workflow blueprints which acts as both the warehouse and supply chain. Repos can be synced with upstream/downstream repositories. License Server: The service which controls the authorization of component technologies; also used to authorize Imagine Communications applications. Zenium Agent: Used for distributed network deployments such as Imagine Communications SelenioFlex File and Imagine Communications Broadcast Manager. The Zenium Agent includes the Zenium Server service and the Agent Communication service. These services can communicate with the Zenium Repository to acquire Zenium Plugin Packages (including the Zenium Framework and Zenium Designer), and they can communicate with the management applications. Key Benefits of Zenium Benefits provided by the Zenium Designer and Zenium Blueprints and Graphs Frame by frame or audio sample by audio sample processing and decisions Logic branches provide a way to make decisions on the data processing based on user- defined conditions Data branches run independently from each other. That means that an error in one branch will not cause the data processing in another branch to fail. Multiple input files can be used by a blueprint to meet the needs of the workflow. Multiple output files can be created by a blueprint. Full visibility into exactly what the workflow is doing at every stage. Data can be previewed at any point in the workflow using data taps, and preview windows can be attached to any component in the workflow. Benefits provided by the Zenium Repo/Catalog One catalog of technologies can be updated with the latest components, and all Zenium applications can then pull the new components from that central repository. The Repository can store more than one version of a component, making it possible to continue to use different versions for different graphs, for example, using one version in production while using a new version in a test environment prior to roll-out. Additional benefits of Zenium Bottlenecks due to limits in purchased licenses can be easily identified 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 5

6 What is Zenium Zenium s open ecosystem and rich third-party support allows third party technologies to be easily integrated into a workflow as a Zenium component Zenium Designer The Zenium Designer is the graphical interface that can be used to create and to run blueprints and graphs. The blueprint is the master file that contains all of the information about the Zenium workflow. A blueprint can contain one or more graphs and/or links to external data required by the workflow. A graph is a set of connected Zenium components. A graph can be an entire workflow solution or it may be a specific sub-set of a solution, intended to be used in a blueprint along with other graphs. A graph can also be embedded within another graph as part of a more complex workflow. Components are the data processing elements. Components have pins which are used to pass data between components (inputs and outputs), to expose properties and events, and to trigger commands. Components also expose properties in the panel to the right of the interface. These properties allow the user to set some of the parameters which define what happens to the data when it is processed by the component. Some component properties are only shown when the Advanced option is enabled and some properties are read-only. Zenium Based Applications A Zenium-based application runs Zenium blueprints and graphs Imagine Communications Corp. Proprietary and Confidential. Product Version Page 6

7 What is Zenium The application can provide direct access to the Zenium Designer, with the user choosing and connecting the components in the graph (e.g., SelenioFlex File). Alternatively the application may present users with the parameters needed for their specific implementation, and based on these settings the graph is created programmatically, and the actual graph is not displayed to the user (e.g., StreamZ Live EX). At a minimum a Zenium based application will normally provide a way to select the data inputs (e.g., source files or live inputs), to set the outputs (e.g., archive files or live output streams), to set some processing options, and to monitor the progress as the data is processed Imagine Communications Corp. Proprietary and Confidential. Product Version Page 7

8 What is Zenium Zenium Components Adding a Component to a Blueprint When you launch the Zenium Designer it will open with a new blueprint. To the left there are two panels: User Files and Repository. The Repository panel is a tree view of all of the components that are available. Expand the tree to find the component that you want to add to the blueprint. Select the component and drag it onto the blueprint. Note that the field next to the Repository label is a search function. Entering text in the field will search for the matching text in blueprints', templates' and components' names and descriptions. Core and Compound Components Components are individual technology implementations, intended to do a specific thing. For example, to encode an MP4 file which contains AVC video and AAC audio you would need an AVC Video Encoder, an AAC Audio Encoder, and an MP4 File Muxer. Some components are self-contained "core components" Imagine Communications Corp. Proprietary and Confidential. Product Version Page 8

9 What is Zenium Components can also include other components, as compound components. Compound components are presented in the graph as one component with an additional green "S" button in their title bar. When the "S" button is clicked the individual components being used internally by the compound component will be shown. For example, the WAVE Encoder component is shown in the graph as a simple box with a green S button in the title bar. Clicking on the green S button shows the internal components used by this compound component. The internal components may also be compound components, as in this example, and can also be expanded. Expanded compound components will show a lock icon next to the name of the component. The lock indicates that the contents of the compound component are read-only. That is, you cannot add or delete an internal component, or make a connection to any of the pins of the internal components. If you want to modify the internal components of a compound component, for example for troubleshooting purposes, then select all of the internal components, right click on one of the selected components and select copy. Then right click on the black background of the blueprint and select paste. You can also want to right click on the pasted components and select Group, to keep the newly pasted components together to make it easier manage in the blueprint. Compound components are designed to bring together all of the individual components that are normally required to do one specific type of data processing. These components may be static, where the same interior components are always present each time the component is used, or they may be dynamic, where the interior components are determined programmatically, depending on the detected input. One commonly used dynamic compound component is the Media File Input component. This component will include different internal components depending on which type of input file has been selected. The component will include the appropriate demultiplexer, video decoder, audio decoder, and/or any other components required to extract data from the file. In the WAVE Encoder component shown in this section, the compound component includes an Audio Format Converter. The Audio Format Converter will modify the input data before passing it on to the WAVE Encoder Core if the WAVE Encoder Core cannot use the unprocessed input data. It is possible to add both of these components to the graph manually, instead of using the compound component, but in most situations it is simpler to use the compound component Imagine Communications Corp. Proprietary and Confidential. Product Version Page 9

10 What is Zenium Component Pins Components have input pins and/or output pins. Some pins will be shown by default when the component is added to the workspace. Depending on which properties are detected by the component additional pins can be created automatically by the component. For example, the 2 Media File Input components shown below have two different types of files loaded. More output pins have been automatically created for the file on the right to give access to the types of data that can be extracted from the selected input file Imagine Communications Corp. Proprietary and Confidential. Product Version Page 10

11 What is Zenium Data Types Double clicking on a pin will open a dialog which shows you the data types that are used by that pin, along with any values that have been detected. In the example below the data types are shown for the Uncompressed Video output pin. The section at the top shows the all of data types that are present for this pin, and the section at the bottom shows all of the Name/Value pairs that are used by all of the data types. If a single data type is selected in the top section, then just the Name/Value pairs for that data type will be shown in the bottom section. Output pins can be connected to input pins by clicking an output pin and dragging to an input pin. If you want to delete a connection, click on the connection and it will turn blue. You can then press delete on your keyboard to remove the connection Imagine Communications Corp. Proprietary and Confidential. Product Version Page 11

12 What is Zenium Warnings and Errors If a pin shows an orange glow, then a problem has been detected. This may be a mismatch between a data type used by the output pin and a data type that can be used by the input pin. A problem may also be detected because some required metadata is missing. Double clicking on the pin will give you more information about the detected problem. If a component has a configuration issue, for example, because of a missing input which is required to configure the component or because the settings within the component are incompatible, then a configuration warning button will be shown. Hovering over the orange "C" button will display a tooltip with the detected warning. When you run a blueprint if a component cannot run due to a detected error a red "E" button will be shown and the border of the component will turn red. Hovering over the "E" button will display a tooltip with the detected error. Clicking on the red "E" button will open a dialog that shows the error along with any other errors detected in the blueprint. Components in Plugins and Blueprints Components are stored in Plugin Packages which can be stored in a Plugin folder or in the Zenium Repository. When you save a blueprint or a graph it includes the information needed to retrieve the component, and any settings that were entered by the user, but not the component itself. Components 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 12

13 What is Zenium are "linked" to the blueprint or graph rather than "embedded". If the component is updated in the Plugins folder or Repository, then the next time that component is opened in a blueprint or graph it will load the updated component. Component Properties (Settings) When a component is selected the component s background color will change from gray to blue, and the properties for the component will also be shown in the right hand panel. At the top of the panel there is an option to show or hide the "Advanced" properties. You can also double click on a component to open the properties dialog, which is useful if you need to open more than one component's properties at the same time to compare settings. When you save a graph the settings for each component are saved with the graph. To the right of each settings field there is a button with a small square. Clicking on this button gives you a list of options. Edit: An advanced dialog that allows you to define the value that will be used. Clear: Clears the value that is being used (sets the property to null). Reset: Resets the value back to its default setting. Key Frame: This dialog allows you to set property values that change over time Imagine Communications Corp. Proprietary and Confidential. Product Version Page 13

14 What is Zenium For example, to use an Audio Level Adjuster component to set the audio volume to increase during the first 3 seconds of the clip, and then remain constant, fading out during the last 3 seconds of the clip (for a 22 second clip): Expression: This dialog allows you to set the property value by evaluating a set of "expressions" when the blueprint is run. The available expressions will be shown as a list when you enter a "$" in the expression field. Expressions which start with "ROOT" will derive the value from the root of the blueprint. Expressions which do not start with "ROOT" will derive their value from the current component. In the following example, the ROOT properties shown are the properties that are available when using a Transcode Blueprint. Expressions are commonly used by the File Output component to create the output file name Imagine Communications Corp. Proprietary and Confidential. Product Version Page 14

15 What is Zenium Script: Property values can be defined using a script. The default scripting language is groovy. If another language is used it can be specified as the first line of the script, for example for JavaScript the first line would need to be: $script_engine_name = "javascript" Delete: Remove the property from the component. Use this with caution, as it is not simple to add a property back once it has been deleted. View Definition: A dialog that shows a complete definition of the property. Publish: A component's property can be made accessible from the root graph using the Publish function. This can be useful if you would like to make just a few key settings available from the root graph, intending to leave the remaining properties set to their default values. Publish Group: Component properties are often shown in groups, so that related settings can be shown together. The Publish Group option allows the entire group to be published by just using the Publish Group option for one of the properties in the group. Note that sub-groups included in the group will not be published using this option; sub-groups must be published independently. Examples The following examples show how to use Publish, Script and Expressions. Example: How to set output file name to use the source file base name This example shows how to set output file name to use the source file base name (that is, the source file name, excluding the source file's path and file extension) in a standard blueprint. (See the following example for achieving the same thing using a SelenioFlex File blueprint.) Step 1: Add a new property to the Media File Input component for the "File Base Name". Add the Media File Input component to a blueprint. Right click on the component and select Add Property Imagine Communications Corp. Proprietary and Confidential. Product Version Page 15

16 What is Zenium Enter a Property, a Display Name, select STRING as the Value type, and click Save. In the right hand properties panel you will see your new property has been added. Click on the button to the right of the File Base Name property and select Script. At the top of this dialog select New. In this case the source file name displayed in the Media File Input component's File property will be used. Move your mouse pointer over the File text label, and you will see a tool tip that shows "File (filename)". The value within the brackets is the property. Enter that in the Property path, Script variable, and set Type to STRING. Click Save. In the lower panel enter the script to use. In this case, use the following groovy script: 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 16

17 What is Zenium if (filename!= null) { filename = new File(filename).getName() int x = filename.lastindexof('.') if (x>0) return filename.substring(0,x) return filename } return "" When you click Save your script will run, and you will see the value returned in the field in the Media File Input component. Step 2: Publish the "File Base Name" property to the root of the graph Click on the button to the right of the File Base Name property and select Publish Imagine Communications Corp. Proprietary and Confidential. Product Version Page 17

18 What is Zenium Click the Publish button and the property will be shown as a property on the root blueprint. To see this property click the blueprint background, then look at the property panel shown to the right. Step 3: Using the File Base Name in the File Output component Select the File Output component, click on the button to the right of the File property and select Expression. Enter the file path you want to use for your output file. Enter a $ to show all the possible expressions that can be used by this component, scroll to the bottom of the list, and you will see an expression for your new property. Enter a file extension and click Ok. Your output files will now use the same base file name as your input files. Example: Using Expressions in SelenioFlex File Blueprints A SelenioFlex File blueprint has been pre-configured to allow it to work with the SelenioFlex File application's watch folders. Additional root blueprint properties are available that can be used in expressions. Note that SelenioFlex File blueprints can also be used outside of SelenioFlex File, to run independent jobs, allowing you to take advantage of these additional root blueprint properties. When you are running a SelenioFlex File blueprint as an independent job, simply do not hook up the "Primary Source File", "Clip List XML" or "Output File/Asset" components that are present in all SelenioFlex File blueprints. This example shows how to set output file name to use the source file base name (that is, the source file name, excluding the source file's path and file extension) in a SelenioFlex File blueprint. (See the previous example for achieving the same thing using a standard blueprint.) 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 18

19 What is Zenium Step 1: Open a Transcode Blueprint, add a Primary Source File From the main menu select File > New Workspace > Transcode Blueprint. Click anywhere on the background of the blueprint. To the right is the properties panel for the root Transcode Blueprint. Near the top of this panel is the "User Input" group of settings. Find the Primary Source File property, click the browse button and browse to your source file. Note that in the Auto-Populated group on the properties panel the values that are derived from the source file will be filled in as soon as a Primary Source File has been selected. These properties can be used in expressions. Step 2: Create your blueprint, including at least one Media File Input and one File Output component. Select the Media File Input component, click the button at the end of the File property, and select Expression. Enter a $ sign, pick "ROOT_primarySourceFile" and click Ok. This will cause the File property to use the same value as the root blueprint's Primary Source File. Step 3: Select the File Output component, click the button at the end of the File property, and select Expression. Enter a $ sign to see the possible options for the file output name. For a transcoded file the output directory and/or the output extension is often different than the source file, but it is often useful to use the source file's base file name, along with some additional data, like the date and time of the transcode. To achieve this, enter the path for the output file, and for the file name enter a $ and use the following expressions (all on one line in the Expression Editor): ${ROOT_sourceFileBaseName} ${ROOT_blueprintStartDateYYYYMMDD} ${ROOT_blueprintStartTimeFilenameSafe} Do not forget to also include the file extension for your output file name. The next time you run the blueprint with a new source file you will just have to select the Primary Source File on the root of the blueprint, and the Media File Input and the File Output file names will be set automatically using the expressions Imagine Communications Corp. Proprietary and Confidential. Product Version Page 19

20 Zenium Blueprints Zenium Blueprints The Blueprint is the master file that contains all of the information about the Zenium workflow. A Blueprint can contain multiple components and/or graphs and/or associated data required by the workflow. Creating a New Blueprint To create a new Blueprint in the Zenium Designer select File > New Workspace > New Blueprint. When you save a blueprint it will be saved as a.zenium file. To create a new SelenioFlex File blueprint in the Zenium Designer select File > New Workspace > Transcode Blueprint. SelenioFlex File blueprints can be associated with watch folders in the SelenioFlex File application. Specialized Blueprints Zenium Graph: This makes a normal, empty blueprint with no specialized controls. Remote Execution Graph: This option creates a graph that is designed to execute remotely on another machine. You can deefine an instance ID, remote host and custom port. This graph might be used when multiple Zeniums are needed to complete a blueprint. The extra options are used to define the engine that will execute the graph. Transcode Blueprint: For use with SelenioFlex File, this type of blueprint can be associated with watch folders. See your SelenioFlex File documentation for more information. Zenium OOP Graph: This type of Graph is normally used for crash protection. This graph will run as a separate Java process within a single machine, as for example when a graph is run on a 32-bit machine (not supported!) and becomes too large for the processor. The excess processing can run as a second process. Or if a component is only available as a 32-bit SDK. Normally that component will be designed to start its own 32-bit process in the background. Zenium Graphs A graph is a set of connected Zenium components. A graph can be an entire workflow solution or it may be a specific sub-set of a solution, intended to be used in a Blueprint along with other graphs. A graph can also be embedded within another graph as part of a more complex workflow. A typical graph contains multiple branches. For example, a media processing graph would normally contain a branch for processing video, and another branch for processing audio. Each branch may also 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 20

21 Zenium Blueprints contain logic branches for handling different types of data, for example a video branch which includes a logic branch to handle interlaced and progressive video differently. A saved graph file contains the names of the components used, the way that they are connected, and the settings for each component. It can also include information about the pins that were last exposed on the dynamic components. For example, if a Media File Input component had loaded an MP4 file which included closed captions and the graph was saved while that file was loaded, then the next time that graph was opened the same closed caption pin would be exposed, even if the source file was no longer available. Creating Graphs You can create and export (save) your own graphs intended to be embedded within blueprints or larger graphs while you are creating a workflow. It may be useful to create a graph if you want to create a reuseable unit which can be available to use in other graphs. Graphs also provide a way to promote (publish) selected properties of the internal components on the root of the graph, allowing you to present a few important settings on the root graph, reducing the complexity of the settings. To create a graph, open a blueprint, add the components that you want to include and connect them together. Multi-select the components by dragging a box around all of the components you want to include. This will cause all of the components to be highlighted in blue. Right click on one of the highlighted components and select Group in > Zenium Graph. This will create a graph within your blueprint. You can give your new graph a name by clicking the title bar of the graph and changing the Name setting in the right hand properties panel. Input pins and output pins will be created automatically based on the connections that were present before the graph was created. To create additional input and/or output pins based on the pins that are present on the internal components, right click on a pin and select "Expose Pin in Parent Graph". You can also create new input pins by selecting the group, right clicking on it, selecting "Add Pin > Input (IO)" and then connecting the input pin of one of the components in the group to the group s input pin. You can create new output pins in a similar manner using the "Add Pin > Output (IO)" right click option Imagine Communications Corp. Proprietary and Confidential. Product Version Page 21

22 Zenium Blueprints To expose settings that are in the interior components as settings for the root graph select a component in the graph, find the property you want to expose, and click the button next to that property. Select "Publish". This will open a "Publish Property" dialog. In the "Publish to" field select the graph (by name). The Published name shown will be the name used by the current property; it must be modified to make it unique before it can be published (in the example above a 2 was appended). The Display name that will be used by the published property can be edited. The Group is the sub-section that will be used to display the property. You can select one with the dropdown or you can edit the text in this field. Click the Publish button to expose the setting as a setting for this graph, rather than just as a setting for the interior component. The following example shows the properties for a newly created graph that includes an AVC and an AAC encoder component. The Video and Audio Bitrate properties have been published to the new graph into a newly created "Rate Control" group. Graphs can be expanded and collapsed using the green "S" button in the title bar of the graph. This is similar to compound components, however, graphs are never locked, that is, the contents of the graph can be modified. To save a graph independent of the Blueprint or parent graph, right click on the graph and select Export Graph (or Save "graph name" if it was previously saved as a graph). Note that the name that you are exporting it to is the file name, and does not have to match the name that will be displayed in the title bar of the sub-graph. Your saved graphs will be shown in the User Files panel to the left of the Zenium Designer (as long as it is saved to a saved graphs directory currently in use) Imagine Communications Corp. Proprietary and Confidential. Product Version Page 22

23 Zenium Blueprints By default the saved graphs directory is the C:\Users\<user.name>\Documents folder. To add more folders right click on the "Saved" folder and select "Add Folder". You can use any exported graph in a Blueprint or a larger graph by finding it in the User Files list in the upper left hand panel and clicking and dragging it into a currently opened Blueprint or graph. You can also right click in the Blueprint or graph and select "Import Graph". This "embeds" the selected subgraph in the current Blueprint or graph. That is, when you save the Blueprint or graph it will include its own information about the components that are used by the sub-graph without referring to the original saved graph. Groups Blueprints can also contain components which are contained in a Group. A group is simply a convenient way of tying together components so that they can be moved together, and so that they can be visually contained in their own rectangle for organizational purposes. Containers To create a container, right-click on the background of your blueprint and choose Add Container. Or, with one or more components selected, right click and select Group In. Either way, the sub-menu contains the following options: Media Looper: Component to repeat media source. Options include Input mode (Auto-Loop or Manual Input), Number of Runs, and offsets. You might use this group if you have a component with a defined life cycle that you need to repeat. Remote Execution Graph: Executes the graph remotely on another machine. In addition to the options that a Zenium OOP graph has, this provides options to set an instance ID, remote host and custom port. This graph might be used when multiple Zeniums are needed to complete a blueprint. The extra options are used to define the engine that will execute the graph Imagine Communications Corp. Proprietary and Confidential. Product Version Page 23

24 Zenium Blueprints Zenium Graph: This is a purely administrative group, with no specialized controls. If your graph is large for easy viewing, you can group components within the Zenium Graph to expand/collapse for clarity, etc. Zenium Graph Stage: This executes the components in the graph based on defined triggers. You can define graph behavior based on what the parent graph does, and based on when it receives a stop command. Start options include Command and/or Parent, and stop behaviors include continuing normally, starting the next stage, and continuing the current stage. This graph might be used in a staged workflow where one part needs to complete before the next can start, as when creating a file to transcode. You would connect one Zenium Graph Stage to another Zenium Graph Stage as a sequence of events. If a Zenium Graph Stage has nothing connected to its start pin it will run as a normal graph. Zenium OOP Graph: Out-Of-Process graph to decouple for crash protection or other reasons. This graph will run as a separate Java process within a single machine, as for example when a graph is run on a 32-bit machine (not supported!) and becomes too large for the processor. The excess processing can run as a second process. Or if a component is only available as a 32-bit SDK. Normally that component will be designed to start its own 32-bit process in the background. Only the items within the container will comply with any special settings applied to it. Templates Templates are pre-created graphs that can be used to help you to build your own graphs or blueprints. They are distributed in plugins, and will be shown in the Repo section of the Zenium Designer, above the Components. You will also see Blueprints in the Repo section, above Templates. The blueprints in this section are pre-created workflows that can be used to help you to build your own blueprints, and they are distributed in plugins Imagine Communications Corp. Proprietary and Confidential. Product Version Page 24

25 Designing a Blueprint Designing a Blueprint A basic blueprint will normally consist of: Input components media file inputs, clip lists Processing components encoders, muxers, metadata, video and audio processing, etc. Output components file outputs, FTP delivery, HTTP delivery, etc. Input Components When you expand the "Inputs" category a number of sub-categories are shown along with 3 input components. One of these is the Media File Input component, and it is the one that is normally used in a standard blueprint. Another is the Clip List Source, which is used in Transcode Blueprints when clip list files are being submitted for processing in SelenioFlex File. Media File Input When you add a Media File Input component to a blueprint it will initially have no output pins. Select the component (it will turn a solid blue color when selected) and the right hand properties panel will show the settings for the selected component. At the end of the File property there is a browse button. Click this button to select the source media. The component inspects the selected file, and then programmatically adds the internal components it needs to extract as much data as possible from the file. An output pin will be automatically created for each data type it can extract. If you have more than one source component to process in your graph, for example, if you have separate video and audio files, then you can add more than one Media File Input component to the blueprint. The component also has an option to use DirectShow for decoding instead. When this is enabled any DirectShow filters installed on the system can be used to attempt to decode the file. This may be 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 25

26 Designing a Blueprint especially useful if the system has a DirectShow filter installed for a format that is not supported directly with a Zenium decoding component. Media Source Component This component allows you to specify which output pins to use. The default pins are Uncompressed Audio, and Uncompressed Video. You can add additional output pins, such as compressed audio, timecode, or captions by selecting the Outputs: Configure Pins button under Media Source properties. In addition to allowing you to specify output pins, the Media Source provides the following additional functionality: Support for heterogeneous source files (can be of different formats with different types of tracks, etc.) Automatic black/silence/empty captions generation for missing data Rule-based selection of timecode and captions sources Support for Extended Clip List Connect either the Primary Source File pin OR the Clip List XML pin to the Source File/Clip List pin of the Media Source component. Both pins will work with a single-file input source, but connecting using the Clip List XML has the added benefit of permitting Clip List XML inputs to also be used without requiring a change to the blueprint configuration. The specific source file that you use at this stage will not be used to run the transcode task, it is strictly for the purpose of setting up the blueprint. The source file used for a transcode task will be the one you drop into the SFX-File watch folder. Clip List Source The Clip List Source component can only be used when you are creating a Transcode Blueprint. A Transcode Blueprint has a special pre-configured pin exposed, the Clip List XML pin, which needs to be connected to the Clip List Source component. As with the Media File Input component, this component will initially have no output pins. Select the root of the Transcode Blueprint by clicking anywhere on the background. This will cause the right hand properties panel to show the settings for the blueprint. For a Transcode Blueprint one of those properties is the "Primary Source File". Choose a file that you plan to submit using the clip list. This will cause a basic Clip List XML file to be generated using that file (as shown in the field under the Primary Source File property) and the Clip List Source component then programmatically adds the internal 2016 Imagine Communications Corp.

27 Designing a Blueprint components it needs to extract as much data as possible from the file. An output pin will be automatically created for each data type it can extract. If your file includes both audio and video you will see pins created for both types of output data. If you plan to add separate video and audio files in your clip list, then you will need to modify the Clip List XML property to indicate typical files that will be used in order to expose the output pins. Click the button at the end of the Clip List XML property and select Edit. Change the "audiosource" file line to use the audio source file needed to populate your output pins, for example: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <cliplist> <clip> <videosource> <mediafile> <file>c:\users\shari.beck\documents\media\myvideo.mpg</file> </mediafile> </videosource> <audiosource> <mediafile> <file>c:\users\shari.beck\documents\media\myaudio.wav</file> </mediafile> </audiosource> </clip> <primaryclipindex>0</primaryclipindex> </cliplist> For more information about Clip List creation and use with SelenioFlex File please refer to the SelenioFlex File. Extended Clip List Format The Extended Clip List is a variant of the legacy Clip List, which permits the use of compressed video and audio inputs and dynamic instantiation of components. A blueprint will either use Extended Clip List or legacy Clip List. When using the Extended Clip List schema the following Media Source features will be available: 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 27

28 Designing a Blueprint Rule-based selection of timecode and captions sources. Each clip in an Extended Clip List can be defined by an "unlimited" number of source files (not just one file for video and one for audio). For example, you can use eight WAV files to generate an 8- channel audio track. Or you can use one file for video, one file for audio and one file for captions. To create an Extended Clip list, your Transcode blueprint needs to include a Media Source component. If the Clip List button is greyed out, you will need to disconnect the Clip List XML pin from the Source File/Clip List pin of the Media Source. Click the square button at the end of the Clips field and select Edit to see the generated Extended Clip List. This will open a dialog that shows the full Clip List xml. You can copy this to a text editor and then save it as a Clip List xml file for submission to a watch folder. For best results, use the Media Source component to create Extended Clip Lists. For more information about this, refer to the Media Source component's help file. Unlike legacy Clip Lists, Extended Clip Lists do not use the concept of a "Primary Clip". This means that when using Extended Clip Lists you cannot use Expressions that include the Primary Source File variable (for example, to set the output file name using ${primarysourcefile} or ${sourcefilebasename}), without declaring the value explicitly. To explicitly declare a value for the primarysourcefile variable when using the Extended Clip List, but you must specify the set runtime property element in the transcode request: <setruntimeproperties> <property propertypath="primarysourcefile" value="\\networkshare\myfile.mp4"/> </setruntimeproperties> Processing Components The majority of the components in your blueprint will normally be processing components. Processing components include specialized components for handling such things as: Encoders, video and audio Multipexers Closed captioning, subtitles, timed text Timecode 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 28

29 Designing a Blueprint Encryption Logic and control Audio pre-processing (e.g., level control, downmix, speed up/slow down, etc.) Video pre-processing (e.g., color space converter, crop, proc amp, scaling, overlay, etc.) Metadata manipulation Audio/Video preview Working with Encoder Components Each encoder component has a compound component which can be found in the Encoders category. These compound components include various format converters so that inputs which are connected to them can be converted to a form which can be used by the core encoder. Normally you should only use the encoder compound components. However, if you want to use the core encoder component outside of the compound component, then you will first have to set your Zenium Designer Visibility from Normal to Advanced. This can be done using the File > Preferences menu. If you are using the core encoder component you will have to be aware of the exact input requirements or the component will generate an error when the blueprint is run. Check the help file by clicking the "?" icon on the component for information on each component. The following is a description of some of the data that is typically handled by the internal conversion done by the encoder compound components. Packed vs. Planar Uncompressed video can store the exact same data using two different data storage methods, packed (where the bits for the Y, U and V components are stored in a single array) and planar (where the bits for the Y, U and V components are stored in 3 separate arrays which are carried separately and must be combined to form the image). When converting to/from packed from/to planar no data is lost, it is just rearranged. Some Zenium components require the data to be carried in one format and some in another. To convert from one format to the other a "Color Space Converter Intel" component is used. The "Sample Layout Strategy" property is set to packed or planar, as needed. Frame Size The frame size (height and width) will normally be part of the metadata carried with the video data. When you are using the encoder compound component you will see Output Width and Output Height fields. If the width and height entered here do not match the input width and height then the video will automatically be scaled Imagine Communications Corp. Proprietary and Confidential. Product Version Page 29

30 Designing a Blueprint Frame Rate and Interlace/Deinterlace The frame rate will normally be part of the metadata carried with the video data, however, some source files may not carry this information. If you are using the encoder compound component and your source does not include the frame rate in the metadata, then you use the Frame Rate property to select the frame rate. If the frame rate you select does not match the frame rate of the input, then the component will frame rate convert the video before it is encoded. The Frame Rate property also allows you to select if the output will be interlaced or progressive. The component will deinterlace or interlace the video as needed. Video Data Type Updater Some video sources will not carry the video data (metadata) required by the downstream components. This data can be manually added by adding a Video Data Type Updater component. Note that this component only adds metadata, it does not process the video in any way. If the Video Data Type Updater has properties for the most common data types in use your workflow requires another type, then you can use the more generic Data Type Merger component. Channel Mapping for Audio Encoders Audio encoders normally have a required channel order. For example most audio encoders require stereo inputs be delivered as Channel 1 = Left and Channel 2 = Right (that is L, R and not R, L). Many source files include the channel mapping as part of their metadata. If the source file does not include the metadata for each audio channel indicating which channel is mapped to which speaker position, then you can use a Speaker Position Assigner component to add that metadata to the source. Use the Encoder Preset Filter to select the audio encoder type that was used by the source media (AAC, Dolby Digital, DTS, WAV, or Custom). Once this has been changed from Pass-through then additional properties will be shown. The Channel Preset drop-down will be populated with channel mappings that are valid for your selected encoder format. Select the appropriate preset for your source media. If you are transcoding to another format which uses a different speaker mapping, then you will also need to remap the audio to the new speaker mapping used by the encoder. The compound audio encoder components include an Audio Format Converter component which includes a Channel Remapper for this purpose. In the encoder's Audio Format Converter section there will be a Channel Preset drop-down menu. Select the appropriate preset for your encoded media, and the audio will use the speaker position metadata to remap the audio. Audio Stream Interleaver You can use this component if you want to process multiple mono input files into one audio stream. For example, if you have 6 mono audio files and you want to make one 5.1 surround audio stream for further processing, then you can use the Audio Stream Interleaver to input the 6 mono streams, 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 30

31 Designing a Blueprint followed by a Speaker Position Assigner component to label the numbered inputs with their audio speaker name (e.g., Left, Right, Center, Low Frequency, Left Surround, Right Surround, etc.). Logic Branches A Logic Branch component may be used to route data to a different branch in your graph based on metadata that has been detected on the input. For example, you may have a variety of input files, some with interlaced video and some with progressive video, and you want all of your output video to be progressive. If you set the logic branch to detect whether the video is progressive, then the "yes" output pin will pass on the data if it is progressive, and the "no" output pin can pass the data on to a deinterlacer component. Taps and Previews While your graph is running it can be quite helpful to see a visual preview or to monitor the data at various points in your workflow. Connect an Audio Video Preview component to an output pin and it will display the video in a preview window on screen, and play out the audio on the system speakers. Connect a VU Meter component to an output and it will create an audio VU meter which visually shows the audio output level for each of the channels detected in the input. A Tap component can be connected to any output pin in the graph. There are no settings for a Tap, it is simply a data collection component. A Probe component can then monitor any Data Property that is available to that Tap, displaying the data detected as either a graph or as a value. Note that the Probe is not connected to the output pin or to the Tap component. The Probe component has a setting that allows you to choose which Tap to monitor. The Audio Video Preview can also monitor a Tap instead of being connected directly to an output pin. This can be very convenient if you want to use one Preview component to step through many output pins. Instead of reconnecting the Preview to the associated output each time, you can use a drop down list in the Preview component to select which Tap you want to monitor Imagine Communications Corp. Proprietary and Confidential. Product Version Page 31

32 Designing a Blueprint Output Components There are different output components available, from the basic single file File Output component to the more specialized HLS and Smooth Streaming output components. The output component needed for each blueprint will depend on the type of processing intended for that blueprint. File Output The File Output component can be used to output a single file. The Write input pin accepts data that can be written directly to a single file, for example, the output from a Multiplexer component. By default the Manual Input property is enabled. When this is enabled the output filename will be entered as the File property setting. There is a browse button at the end of this field to help to define the path for the output file. It is common to use Expressions to define your output file name. Click the button at the end of the File properties field and select Expression. Type a $ in the Expression Editor to see the available expressions. If this is a Transcode Blueprint then you will see expressions for Start Date and Start Time. By adding these expressions to your output filename you will ensure that each time the blueprint is run the output filename generated will be unique. Note that if you are using a Standard blueprint you will not be able to use the ${ROOT_graphStartDateTime} or ${ROOT_graphFinishedDateTime} 2016 Imagine Communications Corp.

34 Zenium Repository (Repo) Zenium Repository (Repo) A Zenium Repository is a collection of Zenium Plugin Packages. The SelenioFlex File 2 installer includes the Zenium Repository. The Zenium Agents used by SelenioFlex File communicates with this Repo in order to acquire new or updated Plugins when running transcode jobs. The Zenium Repository may also be installed as a separate application. This application can be used to sync to the Imagine Communications public repository, to allow updated plugins to be downloaded. A Plugin is a container for a component or a group of related components that includes all of the libraries necessary to run each individual component. The Zenium Repo can store multiple versions of the same Plugin in different repo partitions, making different versions of the same component available when running a job. To open the Zenium Repo Browser from SelenioFlex File launch the SelenioFlex File Console application then select Server > Zenium Repo Browser from the main menu. You may have imported plugins during the SelenioFlex File 2 installation. If not, when you initially open the Zenium Repo Browser it will be blank. From the menu select Plugin > Add Plugins to open a browser window which allows you to select the folder that contains your Plugin folders. You can Delete a plugin, but only after you disable the "Read Only" option in the upper right hand side of the Repo Browser (to prevent you from accidentally deleting plugins). You can add Tags (searchable key words) to each plugin. This may be helpful if you need to sort through the plugins looking for the ones required for a specific reason, for example, for a specific customer's workflow, or for audio encoders only, etc. Select the plugin you want to add a tag to, then click the "Add 2016 Imagine Communications Corp. Proprietary and Confidential. Product Version Page 34

35 Zenium Repository (Repo) Tags" button and add the words you want to use. If you decide to remove one or all of the words in the tag you can use the "Delete Tags" button. To use the tags to filter the list, click the blue "Tags " link found in the top right hand corner. Repo can access other Repos in order to acquire new and/or updated Plugins using the Synchronize function. To acquire a list of Plugins from another Repo disable the Read Only option and then click the Synchronize button. On the Synchronize window enter the URL for the remote Repo's web services server (normally If the Repo has more than one Partition, then select which one you want to use. You can multiselect all the updated plugins, or just the ones you want to update. If you are updating an individual plugin, you should also right click on that plugin and click "Select Dependencies". This will highlight all the other plugins that are required by the selected plugin, so that you can update them at the same time. In the example above, the DRCAVCEncode plugin was selected. By right clicking and picking "Select Dependencies" the additional required plugins were also highlighted. When you are selecting which Plugins you want to synchronize you can also use the filters shown in the panel to the right of the dialog. Once you have selected the Plugins you want to send to your Repo, click the "Synchronize Selected" button found in the bottom right hand corner. You will be shown a status window while the plugins are being pulled from the remote repo to your local repo Imagine Communications Corp. Proprietary and Confidential. Product Version Page 35

38 Zenium Agent System Zenium Agent System A Zenium Agent is a service which runs on a host computer which can communicate with a management application (such as SelenioFlex File 2). The management application sends the Zenium Agent blueprints. The Agent then uses this information to create a new Zenium Engine (an instance of a running Zenium graph) to run the workflow described in the blueprint. A Zenium Agent system can run multiple Zenium Engines simultaneously, returning the status of each Engine to the management software. For distributed network deployments the Zenium Agent is the only software that needs to be preinstalled on a host system. Once the Zenium Agent has been installed updates can be pushed to that system by the management software, or pulled by the Agent in order to run specific jobs. A Zenium Agent that has been installed for SelenioFlex File runs the following services: DRC SelenioFlex File Agent DRC Zenium Server DRC RMI Registry Number of Zenium Resources per Agent System In order to restrict the maximum number of Zenium Resources that can be run on any one host system when using SelenioFlex File, open the SelenioFlex File Console, select Server > Agents, select the Agent you will be configuring, and click the "Add Zenium Resources" button. A newly provisioned Zenium Transcode Agent System will have 0 Zenium Resources. At least 1 Zenium resource must be added before the system can be used to run Zenium Engines. If you need to reduce the number of Zenium Transcode resources available on an Agent system you can go the Resources tab, right click on the resource, and select Advanced > Delete. Adding a resource adds to the maximum number of resources that can be run on the host system, but it does not increase the total maximum number of resources you can use over the entire transcode farm, as that is controlled by the licensing. Normally the number of resources on a single Agent system is limited to a small number, normally 1 or 2. This will prevent all of your jobs from running on a single Agent system, while other Agent systems sit idle with no active jobs. Zenium Engine A Zenium Engine is a running instance of a Zenium blueprint under the control of a Zenium Agent Imagine Communications Corp. Proprietary and Confidential. Product Version Page 38

39 Zenium Agent System A Zenium Engine requires a license to run, along with licenses for the components used in the graph. When the job is finished the licenses are all returned to the pool of available licenses. In SelenioFlex File 2 the maximum number of simultaneous Zenium Engines that can be run on an individual host system can be specified on each individual system (as a setting on the Agent system). However, that does not lock a specific number of Engine licenses to a specific host system, it just specifies the maximum number that can be run before that system will report that is has no available Transcode resources available. The Engine licenses are completely portable and can be requested by any system with a Zenium Agent that has access to the license server. In SelenioFlex File, when a Transcode Resource is running a Zenium Engine, that Resource will be shown as "Busy". Zenium Engines in SelenioFlex File Imagine Communications SelenioFlex File 2 with Zenium Transcode Engines is an example of a Zeniumbased application. The SelenioFlex File application uses the SelenioFlex File Server which manages file transcode jobs. User access to the SelenioFlex File Server is via a Console application. Jobs are submitted to the Server by adding source files to watch folders. Watch folders are associated with transcode projects, where transcode projects are defined by blueprints for Zenium-based transcoding jobs. Zenium SelenioFlex File Blueprints are created by launching the Zenium Designer from the SelenioFlex File Console application. The SelenioFlex File Server has access to a farm of transcode host systems which can run Zenium Engines, and each transcode host system communicates with the SelenioFlex File Server using the Zenium Agent software installed on the host Imagine Communications Corp. Proprietary and Confidential. Product Version Page 39

40 Zenium Agent System When a job is submitted the source file and the Zenium blueprint required by the job are sent to a Zenium Agent on a transcoding host system. The Zenium Agent then manages the Zenium Engine which processes the job. Status is returned to the SelenioFlex File Sever while the job is being processed and when the job completes Imagine Communications Corp. Proprietary and Confidential. Product Version Page 40

41 Zenium Licensing Zenium Licensing Zenium acquires licenses from the Imagine Communications License server. The License Server loads a license package, and the license package includes a list of licensed features and the HASP ID. The Imagine Communications License Server will only load a license package which includes a HASP ID that matches the ID of the HASP attached to the system. General Zenium Licenses: Zenium Framework (the Zenium graph execution libraries) - A blueprint or graph cannot be created or run without a license for this feature. The Zenium graph execution libraries are included in the Zenium Core Plugin Package. Zenium Run Graph - Before a blueprint or graph can run the application needs to acquire a license for this feature. A graph can be created without this feature, it just cannot be run. Zenium Server - A service used for distributed network applications. When a job is received by the Zenium Server it needs to acquire a license for the PRODUCTNAME Framework and the PRODUCTNAME Run Graph in order to spawn a PRODUCTNAME Engine. PRODUCTNAME Run Designer - Required to run the PRODUCTNAME Designer (the visual graph creation application). Note that in order to run the PRODUCTNAME Designer a PRODUCTNAME Framework license must also be acquired. In order to run blueprints or graphs in the PRODUCTNAME Designer a PRODUCTNAME Run Graph feature must also be acquired Imagine Communications Corp. Proprietary and Confidential.
