VC-2

Standardized by SMPTE, VC-2 (also known as Dirac Pro) is a video codec technology developed by the BBC. VC-2 is open source and royalty-free for all to use. It is an intra-frame compression scheme aimed at professional production and post production. Compression ratios are in the range 2:1 to 16:1, and typical VC-2 applications are seen to include desktop production over IP networks, reducing disk storage bandwidth in D-Cinema production and moving HD video over legacy infra-structure. A current application provides near lossless compression to enable the use of HD-SDI to carry 1080/50P and 1080/60P, which would otherwise require new 3G SDI infrastructure.
