How to modify video file metadata?

[gevorg]

I created a bunch of M4V files using Handbrake and I would like to modify some of its metadata, such as Encoded Date and Tagged Date (as shown by MediaInfo). Which tool/program has such functionality? I tried VLC player but it only allows changing basic metadata like Title and Author.

Maybe mp4box

For FFMPEG users, you might also try:

ffmpeg -i "C:\<PathToVideo>\sample004_2.mp4" -metadata date="created=UTC_2014-01-16" -metadata album="Any one you want" "C:\<PathToVideo\sample004_22.mp4"

What you will get when you check is:
General
Complete name : C:\Users\Bud\Desktop\Junk\sample004_22.mp4
Format : MPEG-4
Format profile : Base Media
Codec ID : isom
File size : 4.22 MiB
Duration : 26s 110ms
Overall bit rate : 1 354 Kbps
Movie name : Iron Man (2008)
Album : Any one you want
Recorded date : created=UTC_2014-01-16
Writing application : Lavf55.43.100

All FFmpeg metadata cannot be applied to MP4, only album, album_artist, author, comment, composer, copyright, date, description, episode_id, genre, grouping, lyrics, network, show, title and track.

Just another option for those with ffmpeg use.
