Therefore my question if there's a tool to do it.
exiftool can do some movie formats but not others. pretty likely if there isn't a tool to do it that would be because the format specification hasn't been made public or someone hasn't cared enough to do it but it may also have been done by someone else... AVI isn't done by exiftool, but AVIF is. MOV is, etc. there's also a list of other tools but i haven't checked out what is on there at but perhaps some may work for you: https://exiftool.org/ songbird
