A directors commentary can be presented in many different ways which include an audio over the film/music video or there can be atual footage of directors, which is where the producers and editors are talking to the camera about the product they have created. On disc-based video formats, an
audio commentary is an additional audio track consisting of a lecture or comments by one or more speakers, that plays in real time with the video. Commentaries can be serious or entertaining in nature, and can add information which otherwise would not be disclosed to audience members.
There are several different types of commentary. The two main types simply define the length of the commentary rather than the type of content. They are:
- Partial or scene-specific, which only covers selected scenes of the film. Sometimes these are recorded without the speaker viewing the film and thus the commentator may make more general comments than pointing out specific details.
- Feature-length or screen-specific, which is recorded in one session: the speakers watch the movie from beginning to end and give their thoughts directly based on what is happening on-screen.
