4:2:2

A commonly used term for a component digital video format.

The two chroma components are sampled at half the sample rate of luma: the horizontal chroma resolution is halved. This reduces the bandwidth of an uncompressed video signal by one-third with little to no visual difference.

Many high-end digital video formats and interfaces use this scheme:

  • AVC-Intra 100
  • Digital Betacam
  • DVCPRO50 and DVCPRO HD
  • Digital-S
  • CCIR 601 / Serial Digital Interface / D1
  • ProRes (HQ, 422, LT, and Proxy)
  • XDCAM HD422
  • Canon MXF HD422
