QuickTime is a multimedia framework developed by Apple Computer Inc. that consists of a QuickTime player, the QuickTime framework which provides a common set of APIs for encoding and decoding audio and video and the QuickTime movie file format, .MOV. The MP4 multimedia container is also based on QuickTime technology. The latest version of QuickTime is QuickTime 7, which brought about an H.264 encoder and decoder which supports Baseline, Extended and most of the main profile but not High Profile features.
Quicktime is one of the oldest containers still in use, QuickTime is used by Apple's QuickTime encoding and playback software. It uses an extension of .MOV. It's also very closely related to the MP4 container, which was originally based on this container.
