Apple Intelligence is now available on iPhone, iPad, and Mac!
I upgraded to Big Sur and now I can't even play mp4s offline with Quicktime. I can watch YouTube videos if I drop resolution to 244. Zoom works since because I assume it's a similar video resolution. Is there anything I can do to restore normal video playback? There was never a problem before the upgrade.

Happening to me too, totally should have had a disclaimer about potentially being this unstable. Have a test tomorrow and can't study for it because I can't watch the lectures. Feels like I downloaded a beta not an actual release, telling everyone I know not to update.
I was expecting bugs but not something like downloaded videos being completely unplayable. The audio and video is completely out of sync, trying to skip to a certain section takes forever like I'm streaming it online using 3G, and sometimes it just completely crashes.

I found that restarting my Mac several times seems to fix the issue. I don't wanna speak too soon because it's only been working for the last 15 minutes after restarting 3 times but I would try that.
It's especially crazy because the videos in both yours and my cases aren't even online! Of course, the online ones don't really work either.
I think that solved my problem...thanks!
Big Sur broke medium/high-def Quicktime and browser video on Macbook Pro (early 2015)
