Macbook M4 Max has certain Mp4 files inexplicably show up black and with no thumbnail but with audio intact
Certain Mp4 files will not show anything but a black screen on my MacBook M4 max. They display fine on the device they are copied from. It is only certain ones that inexplicably do this and I can not find any discernable difference in their codecs.
I have been trying for days to find a solution and so far nothing works.
Does anyone have any solutions? I just got this machine and I'm really surprised it can't work with all Mp4 files.
They are black in all apps. Final cut pro, VLC, Quick time, and all preview windows. Thumbnails are simply a "mp4" icon on the ones that won't play visuals, but the audio is intact.
