I'm testing a new way of processing the #DEFCON (And later #InfoCon) videos, can some people help test?

Check out the DEF CON 31 videos and village videos and see if they pseudo stream in your browser of choice.

Download a video or two and see if the subtitle show up in your video player.

The new changes are:
- Now encoded with AV1 instead of HEVC
- Down sampled to 25 frames a second to save on file size
- English subtitles (.srt) are now embedded in the .mp4 file.

All DEF CON video presentations, music, documentaries, pictures, villages, and Capture The Flag data that can be found.

Based on all the positive feedback so far I’ll move to re-encoding to AV1 and embedded subtitles.

I’ve generated caption files for all the village talks that didn’t have them, in the end all past #DEFCON contest will be AV1 and captioned in English.

There is a side project Delchi is working on to generate other language captions off of the English ones, we will be testing that soon with Spanish, German, French and Chinese and add from there.

@thedarktangent Very cool!

Out of curiosity, will there be a process for native (edit: or more fluent) speakers of the other languages to submit patches to iffy translations?

(Thanks!)

@jima That’s a great question! I don’t know of any management system for that so it would have to be manual until a better solution is found.
