AtomicParsley
command line tool can set all the .mp4
metadata tags (supports 3 tag schemes: iTunes-style, 3GPP & ISO), including artwork and long description and even custom tags (I don't know what's this, never used it).
To install:
sudo apt install atomicparsley
To use:
AtomicParsley --help
gtkpod
is a GUI application that uses an atomicparsley
library to set some metadata tags. To work on the .mp4
files you need to turn on the MP4 Plugin in the Preferences.
EasyTag
is another good GUI application that can set the .mp4
metadata tags. It's more easy to use than gtkpod
, but latter can set more tags.
Kid3
is also a very good GUI application that, like EasyTag
, can edit batch of files.
