Directors Commentary

n audio commentary is an additional audio track consisting of a lecture or comments by one or more speakers, that plays in real time with video. Commentaries can be serious or entertaining in nature, and can add information which otherwise would not be disclosed to audience members.

A directors commentary is when the directors on his own or with other members of the production team or cast will talk about the film or particular films in real time with the film playing. 

The below information is taken from wikipedia

• Typically a commentary track will include feature-length commentary from the film's director, cast members, or occasionally writers and producers
• Occasionally actors will perform commentary in-character
• some DVDs include outsider commentary performed by film critics, historians, scholars or fans
• Some DVDs feature commentaries with on-screen video enhancements, such as telestrator prompts
• where one of the subtitle tracks is used to add silhouettes of the speakers in a manner where they seem to be in a theater commenting on the movie as it was screened for them in the style of Mystery Science Theater 3000.

This is a example of a part of a audio commentary from a film.

 

This is my commentary, recorded with just me talking about my final piece as it plays.
