Hello @Manolo & @ohrenkino, I don't tag in Mp4, maybe in the Mp3tag program: Options... → Mpeg, is not programmed in the right way...
Which way would you consider to be the right way?
Please do not mix ID3V2.4 and mp4 tags.
Hello @ohrenkino, I'm working on my MP3 audio file tags with Mp3tag.
I sometimes receive audio files (m4a) that are displayed in Mp3tag: MP4 (MP4)
If one day I want to work on my MP4 audio file tags with Mp3tag, you wrote not to mix MP4 & Id3v2.4 (Id3v2.4 UTF-8).
So my question is, how do I configure Mpeg from Mp3tag to work with MP4 (m4a) tags?
Use MP3tag for mp4 files and MP3tag will take care of it. No special configuration is required.
