I'm trying to set up a thing with ffmpeg to batch convert TV series into a vrchat compatible format using my two video cards in my system. Problem is that before I work on setting up the fun part of parallelizing the workload I have to figure out what's the best quality I can have in vrchat with what they actually support. I know they can't have subtitles as a separate file and it must be embedded, but so far all of my results have not worked when they were uploaded to my vps. Anyone know where I can find this info or what the supported formats are?
