 Container format - Wikipedia, the free encyclopedia
A container format is a computer file format that can contain various types of data, compressed by means of standardized codecs.
Simpler container formats can contain different types of audio codecs, while more advanced container formats can support audio, video, subtitles, chapters, and meta-data (tags) - along with the synchronization information needed to play back the various streams together.
Older formats such as AVI do not support new codec features like B-frames, VBR audio, VFR natively, although the format may be "hacked" to add support, creating compatibility problems.

 Material Exchange Format (MXF)
Object-based file format that wraps video, audio, and other bitstreams ("essences"), optimized for the interchange or archiving by the content creation industries, and intended for implementation in devices ranging from cameras and videotape recorders to computer systems.

Typically a middle-state format for material exchange or archiving; also serves as a final state format for use in a delivery context, e.g., broadcasting.
