It’s very funny you say MOV and HEIC are proprietary and then list MP4 considering
HEIC is just H.265, the video codec, used to encode images
H.264, the codec used for most mp4 files has the same license as H.265 with patent bullshit license fees going on
MP4 container is pretty similar to MOV, and is also not an open standard
this also means MOV and MP4 can be losslessly converted
Apple provides documentation for MOV format free of charge while ISO really wants you to pay to get official standard PDF
All this doesn’t matter anyway because ffmpeg can decode everything (though I guess it might matter in bizarro land where software patents are a thing)
Also Android can totally read at least HEIC images. Not sure about MOV. Any of this is also not related to the problem the OP has.
