ExifTool can only write tags which have been defined. If it isn't one of the 5922 built-in writable tags then you must create a user-defined tag to be able to write it. See the example config file for examples: https://exiftool.org/config.html

Thanks very much. I try to use this command : exiftool -NewEXIFTag=1 1.mp4
but command return:
0 image files updated
1 image files unchanged
it seems new tag NewEXIFTag in .ExifTool_config file is usefull ,but it can not add new tag "NewEXIFTag" in 1.mp4 file.
i will add new tag 'NewEXIFTag' in exif of 1.mp4, how can i do ? thanks.

The MP4 specification doesn't support EXIF-formatted metadata. For this, I suggest using XMP.
