I can vouch for the Youtube captions being edited by anyone, as I have edited their RWBY captions many times before.

The captions are pretty much always written by fans. This was incredibly clear in RWBY Chibi (which had jokes and commentary in parentheses) and the Volume 4 Character Short (which had things like "*FOOT!*" and "*EYES!!!*").
