The .mov multimedia format is a MPEG-4 video container commonly associated with Apple's QuickTime framework. It is the movie file format most commonly praised for bringing feature length in-color movies to the Macintosh with the initial release of QuickTime in 1991. This was before anything comparable was available for the personal computer and Microsoft Windows operating system. This movie format supports multiple sequences of data or tracks categorized into audio, video, effects, and text such as subtitles. A .mov file is considered a resource file. Thus it may or may not be final i.e. it may be self-contained where all video frames and or audio samples are within the file or it may refer to external sources such as other files or data streams using movie references.
Files with the .ac3 filename extension refer to the proprietary audio file format Dolby digital AC-3, developed by Dolby Laboratories. The AC-3 format is from the lossy family of audio compression formats. It supports a variety of audio channel configurations and was the first of its kind to support the full surround sound experience. Because of this, the format has been commonly used in the development of motion picture features designed for theaters and in consumer homes through DVDs and surround sound home theater systems. The AC-3 format is one of the supported audio codecs of the ATSC standard ' a set of standards developed for digital television transmission in several affiliated countries.
