Overview: Supplementary videos
Supplementary movie videos attach supporting material such as extras and trailers to a feature.
An interview or trailer can belong with a movie without being another version of its main programme. The association and presentation role determine how that video should appear in a library. These topics explain those roles so supplementary material stays recognizable beside the feature.
Movie extras
Movie extras are supplementary resources whose role and relationship to a feature distinguish them from another complete movie version.Movie trailers
A movie trailer is a promotional video associated with a work or release, with its own edit, language, resource and playback role.
