Before presentation at the 2002 Sundance Film Festival, Dolby Laboratories' Dolby E technology was used to encode the movies "Technolust", "Amandla! A Revolution in Four-Part Harmony" and "The Kid Stays in the Picture". The films were shown in Dolby Digital 5.1.
Dolby E is an eight-channel professional audio coding system designed for editing and broadcast distribution. The Dolby E frame matches the videos so insert or assemble edits on tape and audio-follow-video cuts between programs can be made without audio noises. The Dolby E signal is decoded at final master control and re-encoded into Dolby Digital for presentation to viewers.
The system is designed to work with multiple video standards and supports 29.97, 25, and 24 fps, with 20- or 16-bit audio words. The system also carries metadata, which allows for functions such as downmixing, which ensures proper playback of 5.1 material over any number of audio channels.
