Short clips are a typical means to promote music. Such clips, whether they are audio or audio-visual, can be used as previews or as independent sound recordings or videos. The way they are handled depends on whether or not the clips have the same core metadata (title, artist name) as the recording from which they are taken.

Previews and clips that share core metadata with the host recording

Clips are being described in ERN 4.3 in SoundRecording/SoundRecordingEdition/TechnicalDetails/ClipDetails. In ERN 4.2 and earlier it was SoundRecording/TechnicalDetails/PreviewDetails. This composite enables the communication of how clips can or were generated from the host recording and whether the clip is:

  • A preview, i.e. a clip created for the specific purpose to promote the host recording; or
  • A standalone clip, i.e. a short clip that can be used in various scenarios, for example in user-generated content.

The availability of such clips whether previews or not is determined by data provided in the relevant Deal as well as the ReleaseVisibility and TrackReleaseVisibility composites linked to the host recording.

Clips that do not share core metadata with the host recording

If the title of such a clip changes for example, by adding a subtitle of “Clip with chorus for UGC” the above solution does not work. The ISRC standard requires that the audio of this clip be treated as a separate sound recording, allocated its own ISRC.

To communicate such a scenario using the ERN standard, the NewReleaseMessage will contain, for each such recording, two SoundRecording copmposites: the host recording and the clip recording. These two sound recordings must be related to one another via the RelatedResource composite with a value of IsClipFrom (in one direction) and HasClip (in the other).

The host recording will be referenced, as usual, from the album release and a track release. In addition, the clip sound recording will be referenced from a further Release composite of type AudioClipRelease or VideoClipRelease.

The availability of such clips is governed by data provided in the relevant Deal as well as ReleaseVisibility and TrackReleaseVisibility composites linked to the AudioClipRelease or VideoClipRelease.
