Automation in Post-Production — Boris Polyak for NATEXPO 2016
- 1. Automation in Post-Production: Fighting the Progress Bar Boris Polyak Head of video editing facility Red Square LLC, for NATEXPO 2016
- 2. Post-production of entertainment television • Entertainment is not news, nor sports, nor cinema • Strict deadline, like in the news • Lots of cameras, like in sports • Emotional complex storytelling through video editing, like in movies • Stuck with the same computer hardware and editing software • Extra challenges, same tools • Each show requires its own workflow
- 3. Parallel workflows take less time Ingest Profiles editing Story editing Video editing Sound sweetening To tape Ingest Profiles editing Story editing Video editing Sound sweetening To tape
- 4. Indivisible workflow steps —three kinds • Creative tasks • The story is created here, with decisions made by humans • Could not be automated (yet) • Software and hardware should not interfere with decision making • Technical tasks • Do not involve decision making • Should be eliminated if possible, or at least automated • Software and hardware should not turn creative tasks in technical tasks • Examples: multicamera track synchronization • Progress bar meditation • Should be replaced with automation
- 5. The progress bar meditation
- 6. Automation in video editing • Automating progress bars: • Makes tasks parallel and takes them out of the project critical path • Lowers the possibility of errors and overall length of project • Increases the relative share of creative tasks • More time for creative tasks might lead to better product quality • The longest progress bars, because digital video is so “heavy”: • Copying from storage to storage • Transcoding
- 7. Methods of automation • One step: copy or transcode • Several steps: copy, then transcode, then copy • Workflow automation, workflow orchestration: • Branching • Decision making: if – then – else • Use and generate variables for decisions: • File size, file name, file location • Metadata • Content analysis: video length, frame size, loudness, color space, aspect ratio, length
- 8. Telestream Vantage • Transcoding into all professional codecs and containers • Decoding everything that is supported by DirectShow • Copying to every possible destination • Local, SAN, NAS, SFTP, FTPS, WebDAV, S3, Aspera • Nexio, GrassValley AMP, Avid MediaStream • Video analysis • Size, field dominance, codec, bit depth, color space, metadata • Letterboxing, pillarboxing, loudness analysis and correction • Integrated with auto-QC such as Vidchecker, InterraSystem Baton • Decision making based on analysis results
- 10. Decide what to do based on the frame size
- 11. Take several different actions based on the file name
- 12. From our experience • Small automations can solve big issues that didn’t look big • Any automation should make as many decisions as possible • Document, explain, repeat — humans need that • The simpler the interface, the better • Drop folders • Premiere Pro panel • МАМ integration should be easy • Monitoring and high availability become important fast • Feedback from the system matters (even though it is the less obtuse progress bar, yes)
- 13. Job Status View provides online monitoring for Vantage tasks
- 14. Post-production automation goals • Increasing time spent on creative tasks • Reducing downtime and error rate • Computers are better at some technical decisions • Partial automation is better than no automation • Taking tasks out of critical path • Long tasks automation • Transcoding • Copying from storage to storage
