Render as an image sequence instead of a video file (we can add any audio back in Premiere very easily). If it crashes again, start rendering again, but start from the frame it quit on. See if that works.
how exactly do I do this? If it's simply attemptping to export as a tiff sequence, I've already tried this and it failed.
nevermind, I have solved the problem. It turns out it was an oversight on my part regarding the dimensions of the floor I used in the video. So simple that I completely glossed over it!
But in any case, I appreciate your advice! I'll mark you as the correct answer!
to those experiencing the same issue:
check each and every file/composition's dimensions in your project window. If the error gives you a certain dimension find that identical dimension and replace it. Don't forget to check the solids folder, that's what ended up tripping me up.
Thanks for sharing the solution.
