Ich habe mal geguckt, welche [QuickTime/MP4-Metadaten-Atoms/-Boxes](http://mp4ra.org/#/userdata) andere Programme laut ihrer Doku unterstützen und sie mit Mp3tag verglichen. Möglicherweise macht es Sinn, das eine oder andere auf eine Variable und damit ggf. auch auf ein ID3-Feld zu mappen sowie ggf. die Werte aus seltener verwendeten Atoms in semantisch äquivalente zu kopieren.

## FFmpeg

Für FFmpeg habe ich keine offizielle Doku gefunden, aber das [Multimedia.cx-Wiki](https://wiki.multimedia.cx/index.php/FFmpeg_Metadata#QuickTime.2FMOV.2FMP4.2FM4A.2Fet_al.) wird öfter erwähnt. Sie scheint nicht ganz aktuell und vielleicht auch nicht ganz korrekt zu sein, aber besser als gar nichts.

- Ich bin mir nicht sicher, ob die korrekte Schreibung des Feldes für das `ARTIST`-Atom klein `©art` oder groß **`©ART`** ist.
- Mp3tag matcht `COPYRIGHT` auf `TCOP` in ID3v2 und `cprt` in MP4, aber FFmpeg matcht `copyright` auf **`©cpy`**.
- **`©too`** (_Tool_) wird für Mp3tag nicht dokumentiert, FFmpeg speichert darin unabänderbar die libavformat-Version. Es könnte äquivalent zu `ENCODEDBY` (ID3: `TENC`) oder `ENCODERSETTINGS` (`TSSE`) sein.
- FFmpeg unterstützt offenbar nur `©gen` und nicht `gnre` für `GENRE`.
- `PODCASTDESC` mappt auf `TDES` (ID3) und `ldes` (MP4), aber FFmpeg kennt nur letzteres als `synopsis`.
- `YEAR` steht für `TYER` bzw. `TDRC` (v2.3 vs. v2.4) und `©day`, während FFmpeg `date` auf `TDRC` abbildet, aber `year` auf `©day` _und_ `TDRL`, was Mp3tag als `RELEASETIME` bezeichnet.

PS: FFmpeg schreibt manche Boxen nur in bestimmten Modi (MP4 vs. MOV vs. 3GP) und verwendet beim Lesen zum Teil andere Variablennamen als beim Schreiben, v.a. mit Unterstrich für Sortierfelder, oder unterscheidet sie nur beim Schreiben und nicht beim Lesen (z.B. `author` vs. `artist`):

# ExifTool

Die [Doku für ExifTool](https://exiftool.org/TagNames/QuickTime.html#ItemList) ist äußerst umfassend.

## `ItemList`

- `PODCASTID` (_Episode Global Unique ID_) wird in der Mp3tag-Doku klein `egid`, bei ExifTool aber groß **`egID`** geschrieben.
- Daneben kennt ExifTool weitere MP4-IDs:
  - **`atID`** (_Album Title ID_),
  - **`plID`** (_Playlist ID_),
  - **`prID`** (_Product ID_),
  - **`akID`** (_Apple Store Account Type_) und
  - **`sfID`** (_Apple Store Country_).

- Für `CONTENTGROUP` gibt es neben `©grp` auch das Atom **`grup`**.
- Für `TITLE` gibt es neben `©nam` (_Name_) auch das 3GP-Atom **`titl`**.
- Für `ALBUM` gibt es neben `©alb` auch das 3GP-Atom **`albm`**.
- Für `COPYRIGHT` (`TCOP`) gibt es neben `©cpy` auch das 3GP-Atom **`cprt`**.
- Für `ARTIST` gibt es neben `©art` auch die Atoms **`©aut`** (QT) und **`auth`** (3GP) für _Author_.
- Für `COMPOSER` gibt es neben `©wrt`(_Writer_) auch das Atom **`©com`**.
- Die Atoms **`perf`** (_Performer_, 3GP) und **`©nrt`** (_Narrator_) scheinen Mp3tag unbekannt zu sein.
- Für `PUBLISHER` (ID3: `TPUB`) gibt es das Atom **`©pub`** (_Publisher_), das Mp3tag nicht zu kennen scheint.
- Das boolesche Apple-Atom **`itnu`** identifiziert(e) offenbar akademischen Content von _iTunes U_.
- Für `GENRE` kennt ExifTool neben `©gen` und `gnre` (3GP) auch **`geID`** (_Genre ID_).
- Für `DESCRIPTION` kennt ExifTool neben `desc` auch **`©des`** (QT) und **`dscp`** (3GP) als _Description_.
- Für `YEAR` oder `RELEASETIME` kommen neben `©day` auch **`yrrc`** (_Year_, 3GP) und **`rldt`** (_Release Date_) infrage.

PS: `©swr`, `©mak`, `©mod`, `©xyz`, `©key` sind weitere spezifische Atoms für QT/MOV.  
PPS: Ich glaube, ich habe immer noch keine richtige Ahnung von MP4-Atoms/Boxes.

Tolle Auflistung. Apple hatte auch das Dokument "iTunes Metadata Format Specification" publiziert. Die erste version 2005, die letzte Aktualisierung die ich kenne war von 2008. Das Dokument stellt Apple schon seit einigen Jahren nicht mehr zur Verfügung. Aber es war maßgebend für viele der Tags, die Musikplayer und -tagger unterstützen, da die meisten versucht haben zu iTunes kompatibel zu sein. Hier sind die relevanten Tags aus der Spezifikation:

`©gen`: Freitext, `gnre`: Genre-ID aus der ID3-Spezifikation.

`grup` für grouping erwähnt das Dokument auch. Aber aktuelles iTunes / Apple Music verwendet tatsächlich `©grp`. Vielleicht wurde das später geändert oder war schon immer so. Ich weiß nicht ob `grup` gelesen werden würde.

`©art` ist normalerweise der Künstler, der auch die Credits bekommt. `©aut` ist ganz klar der Autor (Text und/oder Musik).

Die Seite hat scheinbar was Metadaten für Musik-Dateien angeht recht wenig relevant. Keines der in der Praxis relevanten Atome ist dort gelistet (`©alb`, `©ART`, `aART`, `covr`, `©gen`, `©nam`, ...). Ausnahme ist `cprt`.

Und selbst von denen, die dort aufgeführt sind, wären nur wenige für Musik wirklich relevant. Ein paar wenige wie `albm`, `coll`, `gnre`, `cprt` und evtl. noch ein paar mehr. Aber in der Praxis unterstützt wird dann eher was Apple mit iTunes und ihrem Store liefert.

## Vorschlag

Unabhängig davon, ob iTunes/Music die Daten tatsächlich verwendet, würde ich @Florian für Mp3tag vorschlagen, die folgenden MP4-Boxen für existierende ID3-Variablen hinzuzufügen, zumindest die fett hervorgehobenen:

| Name in Mp3tag | ID3v2 | MP4 |
| --- | --- | --- |
| `ENCODERSETTINGS` | `TSSE` | `©too` (`©swr`?) |
| `GROUPING` | `GRP1` | (`catg`? _Category_) |
| `SETSUBTITLE` | `TSST` | (`©snm`? _Content Subtitle_) |
| `SUBTITLE` | `TIT3` | **`©st3`** _Subtitle_ |
| `INVOLVEDPEOPLE` | `IPLS` / `TIPL` | `©src` _Credits_ (`©thx`?, `©cak`?) |
| `MUSICIANCREDITS` | `TMCL` | `©src` _Credits_ (`©thx`?, `©cak`?) |
| `PUBLISHER` | `TPUB` | **`©pub`** _Publisher_, `©mak`? _Record Company_, (`©lab`? _Record Label_) |
| `LYRICIST` | `TEXT` | **`©aut`** _Lyricist/Author_ |
| `ORIGLYRICIST` | `TOLY` | ~~`©aut`? _Lyricist/Author_,~~ (`©swk`? _Songwriter_) |
| `ENCODEDBY` | `TENC` | **`©enc`** _Encoded by_, `©sne`? _Sound Engineer_ |
| `MIXARTIST` | `TPE4` | `©arg` _Arranger_ |
| `ORIGARTIST` | `TOPE` | **`©ope`** _Original Artist_ |
| `ORIGYEAR` | `TORY` / `TDOR` | (`©ed0`?) |
| `ENCODINGTIME` | `TDEN` | (`©ed1`?) |
| `TAGGINGTIME` | `TDTG` | (`©ed2`?) |
| `RELEASETIME` | `TDRL` | (`rldt`?, `yrrc`?) |
| `ISRC` | `TSRC` | **`©isr`** |
| `MEDIATYPE` | `TMED` | (`©fmt`?) |
| `LANGUAGE` | `TLAN` | (`elng`?) |
| `WWW` | `WXXX` | `©url` |
| `WWWARTIST` | `WOAR` | `©prf`?, (`©prl`?) |
| `WWWAUDIOFILE` | `WOAF` | (`©mal`?) |
| `WWWPUBLISHER` | `WPUB` | (`©lal`?) |
| `ORIGFILENAME` | `TOFN` | (`clfn`?) |
| `POPULARIMETER` | `POPM` | (`urat`?) |
| `RATING MM` / `RATING WMP` | `POPM` | (`urat`?) |

Für die folgenden Felder sehe ich keine Entsprechungen:

| Name in Mp3tag | ID3v2 |  
|----| ---- | ---- |  
| `FILEOWNER` | `TOWN` |  
| `FILETYPE` | `TFLT` |  
| `INITIALKEY` | `TKEY` |  
| `LENGTH` | `TLEN` |  
| `MOOD` | `TMOO` |  
| `NETRADIOOWNER` | `TRSO` |  
| `NETRADIOSTATION` | `TRSN` |  
| `ORIGALBUM` | `TOAL` |  
| `WWWAUDIOSOURCE` | `WOAS` |  
| `WWWCOMMERCIALINFO` | `WCOM` |  
| `WWWCOPYRIGHT` | `WCOP` |  
| `WWWPAYMENT` | `WPAY` |  
| `WWWRADIOPAGE` | `WORS` |

Das sollte `©grp` sein, da so auch von Playern unterstützt.

Das kennt Mp3tag schon, aber mit anderem Mapping und entsprechend anderer Bedeutung:

| Mp3tag | ID3v2 | MP4 |
| --- | --- | --- |
| `CONTENTGROUP` | `TIT1` | `©grp` |

Das ID3v2-Frame `GRP1` aus der [Mp3tag-Doku](https://docs.mp3tag.de/mapping) ist nicht Teil des [Standards](https://id3.org/id3v2.4.0-frames), sondern wurde von Apple erfunden:

> [@Support for new iTunes Grouping id3 frame "GRP1"?](https://community.mp3tag.de/t/support-for-new-itunes-grouping-id3-frame-grp1/18523):
>
> With this week's iTunes' release of 12.5.4.42, iTunes is now writing "Grouping" values from its library out to a new ID3 frame "GRP1". Support of this new "iTunes Grouping" frame in Mp3tag would be a very useful alternative to the problematic "Work" / TIT1 frame to store mood & style keywords.

Ich sehe darin das Problem der Kompatibilität mit anderere Software. Falls ich z.B. `SUBTITLE` als `©st3` schreiben würde, könnten andere Programme wie z.B. MusicBrainz Picard oder foobar2000 nicht mehr darauf zugreifen.

Ich gehe davon aus, dass die Unterstützung dann nach und nach umgesetzt werden würde, aber erstmal würde es eine Zeit der Inkompatibilität geben, unter der dann meistens die Benutzer zu leiden haben.

Sind Dir denn Programme bekannt, die die fett hervorgehobenen MP4-Felder unterstützen? Ich frage das aus Interesse und nicht als Teil einer Argumentation.

Nein, ich habe noch nicht untersucht, welche Tag-, Verwaltungs- oder Abspielprogramme diese Boxen lesend unterstützen oder sogar selbst schreiben.  
Es wäre sinnvoll, eine entsprechende Testdatei zu präparieren und in verschiedenen Programmen zu testen.

[Musicbrainz](https://picard-docs.musicbrainz.org/downloads/MusicBrainz_Picard_Tag_Map.html) [Picard](https://picard-docs.musicbrainz.org/en/appendices/tag_mapping.html) und [Foobar2000](https://wiki.hydrogenaud.io/index.php?title=Tag_Mapping) verwenden die private Box `----` mit dem iTunes-Namensraum: `----:com.apple.iTunes:TAGFELD`.

Dem [VLC-Quellcode](https://github.com/videolan/vlc/blob/master/modules/demux/mp4/meta.c) zufolge liest das Programm praktisch alle jemals von Apple dokumentierten MP4-Metadaten-Felder.

## Formatübergreifende Metadatenfelder

# GPAC / MP4Box

> <https://github.com/gpac/gpac/issues/465>

> Hello,
> Currently for iTunes, the -itags list seems really limited:
> MP4Box -tag-list
> Supported iTunes tag modifiers:
> album\_artist usage: album\_artist=album artist
> album usage: album=name
> tracknum usage: track=x/N
> track usage:...

Die [direkte Unterstützung von iTunes-Tags](https://github.com/gpac/gpac/issues/465) wurde in MP4Box erst vor kurzem aktualisiert. Sie entspricht jetzt ungefähr dem Stand von Mp3tag, Foobar2000 und Picard. Außerdem können auch beliebige `udta`-Boxen hinzugefügt und gelesen werden:

- `mp4box -tag-list`
- `mp4box -itags ` _`tag_name`_`=`_`tag_value`_ [`:`_`tag_name`_`=`_`tag_value`_]\*
- `mp4box -itags ` _`filename`_

Ich habe für die folgende Tabelle Informationen aus den Quellcodedateien [`isomedia.h`](https://github.com/gpac/gpac/blob/master/include/gpac/isomedia.h#L6028) und [`constants.c`](https://github.com/gpac/gpac/blob/master/src/utils/constants.c#L1507) zusammengeführt.

## MediaMonkey

[MediaMonkey 5](https://www.mediamonkey.com/wiki/index.php?title=WebHelp:About_Track_Properties/5.0) speichert einige Werte in nicht standardisierten Boxen innerhalb von User Data `udta`. Für MOV werden einige zusätzliche Boxen unterstützt sowie QT-Metadata-Atoms in `mdta:com.apple.quicktime.`. Für beide werden private Felder von iTunes `:com.apple.iTunes:` und WMP `:Xtra:WM/` in `----` unterstützt. Felder in eckigen Klammern werden nur gelesen und nicht geschrieben, darunter 3GPP.
