I am new to video codec(encoding/decoding) stuffs. I am trying to understand deference between H.264(AVC) and H.265(HEVC) HDR video contents. I thought HDR video 'means' it has 10 bit color depth and H.264 does not support 10 bit HDR content. I would appreciate any clarification on this matter. Thank you.

    h.264 does support 10 bit content, as of 2005. In fact the High 4:4:4 Predictive Profile goes up to 14 bits. en.wikipedia.org/wiki/H.264/… – stib Feb 7 '19 at 12:37
  • 10 bits is necessary, but not sufficient for HDR. – Jason Conrad Feb 10 '19 at 7:13
