===4:2:2=== [[File:Yuvformats422sampling.svg|thumb|4:2:2 sampling]] The two chroma components are sampled at half the horizontal sample rate of luma: the horizontal chroma resolution is halved. This reduces the bandwidth of an uncompressed video signal by one-third, which means for 8 bit per component without [[Alpha compositing|alpha]] (24 bit per pixel) only 16 bits are enough, as in NV16. Many high-end digital video formats and interfaces use this scheme: * [[AVC-Intra|AVC-Intra 100]] * [[Digital Betacam]] * [[Betacam SX]] * [[DV (video format)#DVCPRO50|DVCPRO50]] and [[DVCPRO HD]] * [[Digital-S]] * [[CCIR 601]] / [[Serial digital interface]] / [[D-1 (Sony)|D-1]] * [[ProRes|ProRes (HQ, 422, LT, and Proxy)]] * [[XDCAM|XDCAM HD422]] * [[Canon XF-300|Canon MXF HD422]]
