[The following request was written at my request by Microsoft’s AI agent, Copilot] Subject: Feature Request: Support for MP4 Director/Writer Atoms (©dir, ©wrt) Hi everyone, I wanted to float a small feature request that might be useful to others who work with MP4/M4V video files, especially those…

That's totally fine :slightly_smiling_face: It would’ve been to use just the COPYRIGHT tag for the “studio” part of ITUNMOVI. I’ll make this my last input then as the topic’s went on long enough and a solution’s been found. Please just give this a try as it’s worth it. To make a custom tag, use Ext…

That’s honestly a shame that useful functionality - no matter how obscure or simple - has been removed. I’ve checked with the PC versions and there’s no support either. iTunes once the library’s restored is pretty much the same: codirectors is hidden in a sneaky little 🛈 icon in the Description colu…

OK @arb , "Create iTunMOVI" works fine with Plex. Thanks for writing it and thanks for bringing it to my attention. I saw that "this is the answer but you're not going to like it" post on the Plex forum a long time ago and in fact I didn't like it, so I just kept moving - but now I see that it's th…

I don’t know what an iTunes movie is - unless it’s a movie with a .mov file type and I don’t have any of those. But it doesn’t matter, I copied your XML and am going to hold on to it for future reference. Do any of the fields support CSV (comma separated values)? That would simplify the XML by g…

I can’t find an Mp3tag for “PRODUCER” so I guess that means that “Create ItunMOVI” won’t work - and if I really want it I have to code the XML myself ? Or am I looking in the wrong place?

[image] CamdenTommy: I can’t find an Mp3tag for “PRODUCER” See e.g. here: [image] How to match "Producer" in extended tags? General Discussion For old songs, "song writer" is matched to "composer" and "lyricist" in extended tags (well, I think). But how…

Good to hear! I agree, it’s not a great situation but we can at least make the best of what we got. :man_shrugging: [image] CamdenTommy: will it update the mp4 metadata (so I don't have to delete the tag and re-create it) Yes, you can update it from the Tag Panel but it’s a far easier workfl…

[image] arb: [image] CamdenTommy: Although now "DIRECTOR" gets added to the list of ARTISTs Strange. Is this in Mp3Tag or Plex? I believe it’s Plex. And I meant that if I add “arb” as a director in iTunMOVI, Plex correctly displays “arb” as the Director but also adds “arb” to the list…

[image] arb: @ohrenkino ‘s right to point out there’s other values that can be seen as a “producer” like COMPOSER, LYRICIST and PUBLISHER depending on software/your personal workflow. For Plex, it must be read from ITUNMOVI. I understand the point regarding synonyms and euphemisms, but for PRO…

Not sure about the ARTIST/DIRECTOR problem, sorry. Double-check those tags in Mp3Tag in case there’s similarities as Plex does pick up ARTIST. This is what you want to try out in Extended Tags: [2026-02-18 (2)] Delete the old ITUNMOVI, use the action then check out the new ITUNMOVI it creates.
