Apple ProRes is a family of video codecs used for storing and editing high definition video data in Apple's Final Cut Pro. Apple's official whitepaper lists the codec's key features as being:

  • intra-only codecs
  • 4:2:2 / 4:4:4:4 source material
  • 10-bit (12-bit for ProRes 4444) sample depth
  • variable bitrate

Technical documentation on ProRes 422 Standard Definition / High Quality codec

ProRes 422 SD/HQ is the same codec operating on two different bitrates (flavours). Two different FOURCCs are used in order to indicate each flavour:

Flavour name FOURCC Bitrate
Standard Definition (SD) 'apcn' 145 Mbps
High Quality (HQ) 'apch' 220 Mbps
