This topic has been brought up here a few times before, but if you want to extract your team’s videos from vexworlds.tv, I made a tool to automatically do that.
All you need is Python, ffmpeg, and a couple of python libraries.
It’s a little rough around the edges so I’d recommend only trying it out if you’re somewhat comfortable with Python. (Not that it shouldn’t work, I just haven’t tested it on different operating systems or with different worlds streams)
Let me know if it works for you! (or doesn’t :P)
