The Society of Motion Picture and Television Engineers (SMPTE) is currently working on a new video coding standard called VC-2, optimised for professional production and archiving applications, where the emphasis is on quality and low latency.

VC-2 is actually the DiracPro codec, a wavelet-based video compression technology developed by the R&D labs of the UK broadcaster BBC. VC-2 is royalty free.

Declared features are:
  • Intra-frame only (Inter prediction also available if required)
  • 10 bit 4:2:2
  • No subsampling
  • Lossless or visually lossless compression
  • Low latency on encode/decode
  • Robust over multiple passes
  • Ease of transport (can use a range of transport standards)
  • Low complexity for decoding
  • Open Specification
  • Multiple vendor
  • Support for multiple HD image formats and frame rates.
