MP4 has no metadata

[TheMasahiro]

I recently converted a mp4 file in h264 to h265, the converted file has no metadata like quicktime:createdate.

the video is 40 minutes long.

I would like to add this metadata is it possible?

Using exiftool -time:all -a -G0:1 -s  the only metadata is the file access, create and modify date.

i tried

exiftool "-QuickTime:CreateDate=2016:05:05 12:12:12" -overwrite_original

but doesnt seem to work.

Currently ExifTool can't add new QuickTime tags.  It can only add XMP metadata to MP4 files.

There are other utilities that have the ability to do this.  A bit of google should give a solution.
