MPEG-4 Part 10, or H.264
MPEG-4 Part 10 defines a high-quality video compression algorithm called Advanced
Video Coding (AVC). This is more commonly referred to as H.264. H.264 video
compression works similarly to MPEG-1 and MPEG-2 encoding but adds many
additional features to decrease data rate while maintaining quality. Compared to
MPEG-1 and MPEG-2, H.264 compression and decompression require significant
processing overhead, so this format may tax older computer systems.
