100000% yes for every reason under the sun.
You're rendering to an mp4 video, theres a crash or powercut... all your rendering is lost in a corrupt mp4 file
You render for hours or days, then realise the compression is too high and the image quality is ruined
You render for days, then realise c4d is 1-2 frames lagged with its animation as the movement happens after the audio hits, so the entire video looks out of sync
Basically, unless its a quick 5 minute test render, always render to image sequences, virtually no exceptions.
