[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…

[image] CamdenTommy: but no "Actions..." If you have a ready-made mta file, you have to put it into the configuration folder (see File>Open configuration folder) and there into data\actions. If you do not have an mta file, you have to create a new action group with Actions>Actions Alt-6 > Ne…

Please pay more attention to what we’re trying to explain to you, rather than summarising everything in Copilot. I’m sure you’re using it for genuine and helpful reasons but it can only make educated assumptions, it cannot do the actual reading for you. @ohrenkino has offered how to find where to p…

Status Update on MP4 Director/Writer Tagging I wanted to share a quick progress report on my exploration of getting “Director” and “Writer” from Mp3tag into Plex using the iTunMOVI tag. I’ve been digging through this and older Plex and Mp3tag threads, running some controlled tests, and trying to ma…

[image] CamdenTommy: One thing I don’t understand is why, if this process works for Plex — and would presumably also work for Emby and Jellyfin — adding support directly to Mp3tag is considered out of the question, instead of relying on a user‑maintained workaround. More correctly, it would b…

Doesn’t really matter in the grand scheme of things, but the documentation on installing Actions in Mp3tag that I was working from started with an “Actions…” option in the “Actions” menu, and only after a couple of hours of chasing my tail looking for why it was missing did it become apparent that i…

[image] arb: Create iTunMOVI.mta (2.1 KB) Refer to this to install the action into the \Mp3tag\data\actions folder. In Mp3Tag, save what you want into ACTOR, DIRECTOR, PRODUCER, WRITER and COPYRIGHT tags into an MP4 (ACTOR is based on an MKV tag and WRITER is totally custom.) With the MP4 sele…

There are currently 2 options/actions/variations of actions in the Actions pulldown menu: “Actions”, and “Actions (Quick)”. There apparently was also a 3rd action in the Actions menu: “Actions…”. The 3rd action either never existed, or existed at one time but has been removed, or only appears un…

Right, I copied and pasted your Action into the proper folder and tried loading this XML into the extended tag iTunMOVI, so far without success: <?xml version="1.0" encoding="UTF-8"?> director name Florian Heidenreich

That XML isn’t properly formatted. Ignore the action for a second and try putting this into ITUNMOVI: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>directors</key> …
