3 File: XTAccess_ReleaseNote_v1 4 DESCRIPTION OF THE PRODUCT The EVS Export Plug-in is a plug-in designed for Apple Final Cut Pro. Its purpose is to export a sequence edited in Final Cut Pro to the EVS environment (EVS video server or nearline storage). The EVS Export Plug-in first exports a QuickTime Reference file with the sequence settings. It can also send additional XML jobs to XTAccess for post-processing, such as restoring to an EVS video server or transcoding to a file (to generate a proxy file, for example). The general flowchart of the EVS Export Plug-in is described below : Export Plugin Media flow chart Version 2.0 XML job A/V data flows in A/V data flows out EDL Data flow 12 Files on a nearline storage 9 6 5 EVS Server Main Exported Files (Quick Time Reference) 10 11 XTAccess Export 4 7 8 EVS Server Backup 3 Plug-in Export EDL Storage 2 1
4 File: XTAccess_ReleaseNote_v1 Once the sequence is ready for broadcast, the editor will export it to the EVS system. Several actions will be initiated: Consolidate the sequence and create a QuickTime Reference on a temporary storage or nearline storage (3). o Optionally: Create an XML file along with the exported QuickTime Reference file to referencee this file in an IPDirector nearline storage o Optionally: Export the sequence as an EDL (XML) on a storage (2). Post-Processing: Generate XML jobs (4, 7, 11) to EVS XTAccess application in order to: o Restore the exported QuickTime Reference file to EVS servers (Main and/or backup) (5 & 8) ). o Rewrap the exported QuickTime Reference file to another file (for example to generate a proxy file with a transcoding job) o The post-processing jobs are monitored and their status is displayed in a separate window. 5 MAIN FEATURES The Post-Processing can be started during the Export as the Quick Time Reference file can be opened during creation. Multiple Post-Processing jobs can be generated at once XML metadata file can be customized (VarID, Source Name, IPD owner) Referencing into IP Director database is supported All EVS XT native codecs integrated with are supported : o DVCPRO50 o IMX-D10 (30/40/50) o DVCPRO HD (1080i50, 1080i5994, 720p50, 720p5994) o Apple ProRes 422 (LT/SQ/HQ) (1080i50, 1080i5994, 720p50, 720p5994)
5 File: XTAccess_ReleaseNote_v1 6 LIMITATIONS The EVS plug-in need at least Final Cut Pro version 7+. v6 is not supported. The Sequence Name characters. Uncompleted Post-Processing jobs : When the exported QuickTime Reference file is stored on a storage accessed by XTAccess via Samba protocol (SAN, Mac local drive), XTAccess jobs sometimes only process part of the file and the resulting file or clip on EVS video server is not complete. This behavior is due to Samba limitations on file notifications. This is under investigation for improvement in a future release.. The following workarounds are possible: o Activate the FileReader NoBuffering setting on XTAccess : HKEY_LOCAL_MACHINE\SOFTWARE\EVS Broadcast Equipment\Common\FileReader NoBuffering : Specificc setting to read a file without any buffering. Recommended for reading on a MacOS workstation via network (SMB). To activate, set the value to 1. o o can not contain special characters like / or non ASCII 128 Store the exported QuickTime Reference file on a Windows-based storage Select the option in the post-processing job : Send XML jobs when export is over : the plug-in will send the XML jobs when export process is done. In this case XTAccess will only handle exported QuickTime Reference files which are closed (not growing). Cancel Jobs: This function cancels the export of the sequence. When this command is used, the plug-in sends a cancel job to XTAccess to cancel the current scheduled or processed jobs. The cancel job is successful but the jobs arrive too late to be taken into consideration by XTAccess. The cancel feature will be reviewed in a future version crashes: Some crashes of have been observed when exporting sequences (mainly in SD resolution). Such crashes are not related to the Export Plug-in. The same effect is observed when exporting the sequence using the default Export to QuickTime Movie from the export menu. This issue is under investigation with Apple. Mac connected to a SAN via AFP. The Export Plug-in works properly when connected to a SAN storage via AFP. The XML metadata must however be stored on the SAN via SMB sharing and not AFP. AFP does not send any notification to the IPD Scheduler and the media will not be displayed in IPD the database. This works properly with the SMB protocol.
