XAVC

A video compression system developed by Sony and released in 2012. Designed for professional use in acquisition and post production, XAVC uses the highest level (5.2) of H.264/MPEG-4 AVC and offers some things that plain vanilla H.264 XAVC does not, such as encoding 1080/50P and 1080/60P. At the high performance end it supports 4K at both 4096 x 2160 (cinema) and 3840 x 2160 (video) resolutions at up to 60 f/s. With available bit depths of 8, 10 and 12, 4:2:0, 4:2:2 and 4:4:4 sampling and bit rates ranging from 15 to 960 Mb/s, XAVC can be used for a wide range of applications.

As H.264 is an advanced compression system, XAVC can offer high quality performance at relatively low bit rates (and smaller / longer storage) with a choice of either intra-frame or long-GOP codecs. The compressed video can be wrapped in an MXF OP1a container which is widely used in broadcast.

XAVC-S is the 8-bit consumer version of XAVC. It offers lower bits rates than XAVC and is wrapped in an MPEG-4 container. It is designed for the shorter, less complex workflows typical of consumer production.
