I too am having problems with my .mp4 files playing on my MacBook Pro laptop. When I try to play or preview the files, all I get is the audio and no video. Several different .mp4 video files doing the same thing. I CAN download the files to my desktop and they will play, and/or I can access the files from my iPhone 13 Pro and they will play.
