## Real Tags

ExifTool recognizes three basic types of Real audio/video files: 1) RealMedia (RM, RV and RMVB), 2) RealAudio (RA), and 3) Real Metafile (RAM and RPM).

## Real Media Tags

These Tag ID's are Chunk ID's used in RealMedia and RealVideo (RM, RV and RMVB) files.

> 'MDPR' | MDPR | - | --> Real MediaProps Tags
> 'PROP' | PROP | - | --> Real Properties Tags
> 'RJMD' | RJMD | - | --> Real Metadata Tags

## Real FileInfo Tags

## Real Metadata Tags

The tags below represent information which has been observed in the Real Metadata format, but ExifTool will extract any information it finds in this format. (As far as I can tell from the referenced documentation, string values should be plain text, but this is not the case for the only sample file I have been able to obtain containing this information. These tags could also be split into separate sub-directories, but this will wait until I have better documentation or a more complete set of samples.)

> Tag ID | Tag Name | Writable | Values / Notes
> --- | --- | --- | ---
> 'Album/Name' | AlbumName | N |
> 'Track/Category' | TrackCategory | N |
> 'Track/Comments' | TrackComments | N |
> 'Track/Lyrics' | TrackLyrics | N |
