VIDEO ENCODING
  • 8-bit or 10-bit pixel depth
  • Chroma sub-sampling 4:2:0 or 4:2:2
  • BT.709 color space and WCG (BT.2020)

  • SDR and HDR - HLG or PQ (ST 2084) 

  • Configurable Group of Picture (GOP) size
  • I, IP, IBP, IBBP, IBBBP and IBBBBP Framing
  • Bitrates SD/HD from 32 kbps to 120 Mbps**
  • Configurable frame rate

  • Intra-refresh

  • Slice-based encoding 

    Note

    **Maximum bitrate depends on the configuration.

H.264/AVC Profiles
