I've looked at some of the other topics regarding tagging MP4 files and it's never clear to me whether they are referring to MP4-type tags for MP4 files, or all tag types for MP4 files. Just to be clear, my issue / question is in regard to MP4-type tags (as opposed to MP3TAG, ID3, iTunes, etc.)-typ…

Well I think I figured out what I did wrong. I should have known that Florian would lay the mapping table out logically. So since I misinterpreted the headings I reversed the source and target fields. I went back and switched them in the table and everything works fine. Sorry for the false alarm…

But the field ©WRT is in the table as the MP4 name for what MP3TAG internally refers to as COMPOSER. I’m assuming that WRT stands for writer, which makes me think that if I can get what MP3TAG (and MP3) consider COMPOSER to Plex via metadata to Plex as the MP4 metadata field ©WRT, Plex will use it …

COMPOSER already gets written to ©wrt by default, no need to set up a custom mapping for this. What you need to figure out is from which MP4 tag Plex reads the writer, or whether it reads it at all. Their documentation on this is rather bad, all I found was Identifying Music Media Using Embedded M…

And regarding DIRECTOR for use with Plex, I think we've already discussed this here (and concluded, that Plex doesn't get the information from this field). [image] How do I get the "Director" field for an .mp4 from mp3tag to Plex? Support "I confirm the ©dir tag field doe…

Indeed. The same is probably true for the writers, at least the XML mentioned at What MP4 tags can be read into Plex with local assets agent? - #15 by FlixAdmin - Development - Plex Forum shows a screenwriters section. So Plex likely does not read ©wrt either.

The documentation in this regard is really bad indeed. They apparently want users to use their editor and primarily rely on online sources based upon folder and file name matching. If Plex is (still) anything like Kodi/XBMC here, it relies on FFmpeg to read the MP4 user metadata tags . MP4 FFmpe…

Yes I agree the Plex documentation on what the MP4 metadata scanner looks for is very bad. That's what I was referring to when I said guesswork and trial and error. As in, I send Plex some metadata and see what, if anything, it does with it. I did find a thread that attempts to address the issue …

Well you're a step ahead of me. I just posted a link to the thread and was about to mention the part about ITUNMOVI and the xml script that goes with it. Interestingly enough the XML is not necessary for actors because the MP3TAG "ARTIST" tag flows through perfectly. But apparently Director does …

Plex has different scanners and agents, one for movies, one for TV programs, and one for "other" MP4 files such as youtube vids, etc. The movie and TV scanner/agent combos tend to rely on online info sources instead of metadata. The "other" scanner/agent category relies on metadata. The movie and…
