The CRS Ticket Trakcer is the main tool which enables the c3voc to process so many videos during the duration of an event. It's a web-application at https://tracker.c3voc.de which is managing all tasks to record, cut, encode and release a talk based on the event's schedule in the schedule.xml format.
All automation at the c3voc is based on the schedule!
How to Help Us
During an event, we may need help cutting and checking talks. How urgently help is needed depends on how many people from the team are present and how much help we get for operating the halls.
There are two main kinds of help needed:
- Help with normal cutting and checking: You need a laptop and some headphones
- Help with broken talks: You need to know your way around in a video editor of your choice and ideally have experience in piecing together audio and video from different sources
Usually only 0-10% of the recordings need manual editing becuase of a broken recording or becuase something was shown which shouldn't be released. As you may have guessed this work is quite labor-intensive and can take up to a few hours per talk to reach an state which can be released.
Tasks
As mentioned before, we have a highly automated standard cutting workflow, but also a way to manually edit videos if needed.
Normal Cutting
The normal process is mostly automated, but needs manual intervention to set the actual start and end of the talk. See the cutting and checking pages for a detailed descrption what needs to be done.
Reparing Talks
To repair a recording, you need to fetch the source files from where they are stored (depends on the event's specific setup) and do your magic in the video editor of your choice. Just make sure to render the output as 1920x1080px with 25 fps and no timecode track.
Remove a timecode track with ffmpeg using:
ffmpeg -i inputfile.ext -c:a copy -c:v copy -write_tmcd 0 outfile.ext
