Bringing back diffrent source render

[ooTruffle]

For certan maps on a q2 beatsaber is crashing when it tries to load the map again for the auto would there be a way for a. The user being able to just have the audio render and replay seeing the fnished video_temp before the crash and makeing the mp4 b. Replay if beatsaber crashes allowing someoe to "resume" a render c. I if the audio and video are done seporately act like older verisons where it needs to ffmpeg to mp4
