	Motion JPEG is a sub-category of motion video codecs where successive frames are encoded using the standard [[JPEG]] algorithm. No interframe compression is performed and the resulting encoded data generally does not achieve the same level of compression as a codec using interframe techniques. However, decompression is usually faster and any frame can be referenced independently since there are no dependencies on other frames. Plus, there are fewer legal caveats when using the open JPEG standard.		Motion JPEG (a.k.a.
