1 IMF: What does the new mastering format mean to you? What is IMF? A newbies guide Mark Harrison (as Horton) & Bruce Devlin (as Dr. Seuss Bruce) 1

2 What is IMF? Is it a file? No! It s not a file And we don t care whether The title s about a movie Or weather What is IMF? Is it a folder? No! It s not a folder We spent many nights til We found a new way To deliver a title 2

3 What is IMF? Is it an edit? synchronise Original Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Almost Just like an edit The Story we tell Is held in a file We call CPL Captions Virtual Track time CPL What is IMF? So, it is an edit? CPL en synchronise English Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Captions Virtual Track time Almost Just like an edit Avoiding recursion We specify timing Of every version CPL fr synchronise French Composition Image Virtual Track res Audio Virtual Track Audio Virtual Track Captions Virtual Track time CPL de synchronise German Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Captions Virtual Track time 3

4 What is IMF? So, there are many files? CPL en synchronise English Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Captions Virtual Track time Yes To handle more titles Automation exponents Explained for results We must store as components cpl.xml video.mxf subtitles.mxf audio1.mxf audio2.mxf What is IMF? So, many files Many versions? CPL en synchronise English Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Captions Virtual Track time cpl.xml video.mxf audio1.mxf audio2.mxf subtitles.mxf Yes Each file is re-used And unlike days of yore If there s not much you change There s not much you store CPL fr synchronise French Composition Image Virtual Track Audio Virtual Track res Audio Virtual Track Captions Virtual Track time cpl.xml synchronise audio1.mxf subtitles.mxf German Composition CPL de res Image Virtual Track Audio Virtual Track Audio Virtual Track Captions Virtual Track time cpl.xml audio1.mxf subtitles.mxf 4

5 What is IMF? Less to store, Less to send? IMF Package Deliver cpl.xml video.mxf audio1.mxf audio2.mxf subtitles.mxf Yes If there s less that you store Then without too much force You get better use Of your network pkl.xml cpl.xml audio1.mxf subtitles.mxf ASSETMAP.xml cpl.xml audio1.mxf subtitles.mxf What is IMF? Anything else? IMF Package Deliver Yes There s one final trick Which generates flames To automate well We got rid of file names ASSETMAP.xml 5

6 What is IMF? Anything else? IMF Package Deliver We made things efficient, we made all things small It s worth doing well, if you do it at all Humans break workflows, they play little games So, make IMF stable, remove all file names All things in the format, they ve got an ID Which automates searching and finding you see Your workflows are destined to be in the cloud Where traditional file names should not be allowed IMF s really for mastering fast IDs are efficient, IDs always last ASSETMAP.xml IMF s future depends on TV Let see how we get there, with the DPP 6

7 Problem 1: Multiple copies REGIONS COMPLIANCE VERSIONS LANGUAGE VERSIONS CONSEQUENCES Storage a lot Essence Duplication Lots of Management Duplicated Processes (QC etc) Master asset Multiple delivered localised masters per programme title across the globe are stored Lots of deliverables: Resolutions, Formats, Metadata for catch up, VOD, etc. Problem 2: Loss of Knowledge LOTS Number of Assets Increasing assets LITTLE Initial Work Time Localisation/Dubbing 7

8 Problem 2: Loss of Knowledge LOTS Knowledge per asset LOST KNOWLEDGE Original frames (edited over) Original EDLs Scripts Translations Localised M&E Stems CONSEQUENCES No systematic storage of knowledge of process information Increasing assets LITTLE Speed to Market is slow Initial Work Time Localisation/Dubbing Problem 3: Loss of Quality Delivery Frame Rate Multiple Frame rates Multiple Codecs Multiple Bit Rates Multiple Definitions Multiple Colour Spaces Time Programme Master Compliance Dubs & Subs TX VOD Localisation Processes Distribution 8

9 Problem 3: Loss of Quality CONSEQUENCES Quality is reduced Delivery Frame Rate Quality Time Programme Master Compliance Dubs & Subs TX VOD Localisation Processes Distribution So we re looking for: Something that can (This becomes the essence of IMF) Eliminate or at least substantially reduce duplication = Lighter Preserve Asset Knowledge = Faster Preserve Mastering Quality throughout localisation process = Better Lighter + Faster + Better = Cheaper And a great balance between Efficiency and Agility! 9

10 Problem 1: Multiple Copies REGIONS Programme Master COMPLIANCE VERSIONS LANGUAGE VERSIONS KEY POINT Versions are mostly the same content as the programme master! CONTENT UK Master CONTENT + Master asset French Master CONTENT Middle Eastern Master CONTENT Multiple delivered localised masters per programme title across the globe are stored Lots of deliverables: Resolutions, Formats, Metadata for catch up, VOD, etc. 10

11 Problem 1: Multiple Copies UK Master CONTENT Localised Content = Programme Master CONTENT + Which is: New content Where to put it Problem 1: Multiple Copies French Master CONTENT UK Master = Localised Content CONTENT + Which is: New content Where to put it 11

12 Solution 1: It is lighter! REGIONS Programme Master CONTENT COMPLIANCE VERSIONS LANGUAGE VERSIONS LOOKS A LOT LIKE AN IMF STRUCTURE OR BUNDLE Kit of Programme components: Programme Master Master asset LOCALISATIONS + New localised content + AUDIO AUDIO Additional language/ subtitle tracks AUDIO SUBTITLES SUBTITLES SUBTITLES Multiple delivered localised masters per programme title across the globe are stored Lots of deliverables: Resolutions, Formats, Metadata for catch up, VOD, etc. Solution 2: Preservation of Knowledge (Faster!) LOTS HIGH LEVEL OF KNOWLEDGE IS PRESERVED One core master asset Knowledge per asset Increasing assets LITTLE Initial Work Time Localisation/Dubbing Exploitation Speed 12

13 Problem 2: Multiple standalone Edits for each version Norm Master Netherlands CE Middle East Russia LA-PW On Demand USA-PW German Spanish Nordic APAC-1 Arabia AF New Zealand French Etc. Etc Etc. Etc Etc. Etc Pre-watershed Etc. Etc Post-watershed Etc. Etc Etc. Etc Etc. Etc Etc. Etc Time Solution 2: Preservation of Knowledge Production CPL KEY POINT Systematic preservation of knowledge UK CPL CE CPL ME CPL APAC-1 CPL USA-PW CPL LA-PW CPL Time 13

14 Problem 3: Loss of Quality Delivery Frame Rate Multiple Frame rates Multiple Codecs Multiple Bit Rates Multiple Definitions Multiple Colour Spaces Time Programme Master Compliance Dubs & Subs TX VOD Localisation Processes Distribution Solution 3: Much better! Delivery Frame Rate Frame rate 1 Codec 1 Bit Rate 1 Definition 1 Colour Space Time Programme Master Compliance Dubs & Subs TX VOD Localisation Processes Distribution 14

15 Solution 3: Quality Maintained Delivery Frame Rate Quality KEY POINT With only one format in the localisation process: Everything done at single frame rate No loss of quality due to multiple conversions IMF designed to use mastering quality codecs Time Programme Master Compliance Dubs & Subs TX VOD Localisation Processes Distribution BONUS Because you have solved these 3 problems, you get these extra benefits Saved space Easier to manage (manage only 1 copy of master media assets rather than multiple copies of slightly tweaked assets) Because of systematic storage of knowledge it s easy to see consequences of change to media Re-purposing of content is straight forward Any asset (e.g. Language track) can now be easily repurposed on any distributed version without any additional subbing or dubbing work 15

16 IN SUMMARY Identified 3 key problems and have solutions for them Now mapping solutions into real IMF implementation Needed: To confirm all edge use cases Additional tool sets Working closely with vendors to map this out Works out implications for Interoperability DPP/SMPTE specifications to be published as can help with the Industry side of adoption.
