Big Sur broke medium/high-def Quicktime and browser video on Macbook Pro (early 2015)
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.
MacBook Pro 13″, macOS 10.14
