Main 4:2:2 10 The Main 4:2:2 10 profile allows for a bit depth of 8 bits to 10 bits per sample with support for 4:0:0, 4:2:0, and 4:2:2 chroma sampling. HEVC decoders that conform to the Main 4:2:2 10 profile must be capable of decoding bitstreams made with the following profiles: Monochrome, Main, Main 10, and Main 4:2:2 10. [24] Main 4:2:2 12
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
On June 10, 2013, Vanguard Video announced that support for the Main 10 profile was added to their V.265 professional HEVC encoder. [51] V.265 is the first real time HEVC software encoder to support the Main 10 profile. [51] On June 20, 2013, Imagination Technologies announced their PowerVR Series5 HEVC decoder. [52]

x265 is an encoder for creating digital video streams in the High Efficiency Video Coding (HEVC/H.265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC). [ 4 ] [ 5 ] [ 6 ] It is available as a command-line app or a software library , under the terms of GNU General Public License (GPL) version 2 or later ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
The maximum NVENC HEVC coding tree unit (CU) size is 32 (the HEVC standard allows a maximum of 64), and its minimum CU size is 8. HEVC encoding also lacks Sample Adaptive Offset (SAO). Adaptive quantization, look-ahead rate control, adaptive B-frames (H.264 only) and adaptive GOP features were added with the release of Nvidia Video Codec SDK 7 ...
Coding efficiency is the ability to encode video at the lowest possible bit rate while maintaining a certain level of video quality. [2] HEVC benefits from the use of larger CTB sizes. [2] This has been shown in peak signal-to-noise ratio (PSNR) tests with a HM-8.0 HEVC encoder where it was forced to use progressively smaller CTU sizes. [2]
