Need simple MP4/MKV (etc) metadata (at least codec id) editor

[Sinsearach]

Need to change/set (at least) "Codec-ID" of mp4 files.
Preferably in place (no new new file creation).

Needs to be have a GUI (no time for command line stuff).

You would think such a task would be very straight forward these days but just try to find a simple, functional solution.

If there is indeed such a utility in the software section here on VH I swear I must be blind.

Thanks for your time/attention.

Maybe....

Otherwise, no known gui editors of such afik.

Ffmpeg will do it easily.

Otherwise, you'd have to modify this header info reader to write modifications.
