### Interframe versus Intraframe Compression

While the data stream supports both interframe and intraframe compression, no specific distinction is made between frame types. An intraframe compressed frame is one that does not contain any unchanged data. This does not preclude the file format from making such a distinction, as in the Audio/Video Interleaved (AVI) file format. Capture or compression software generally enables periodic insertion of intraframe compressed video frames.
