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.
Version 1: (April 13, 2013) First approved version of the HEVC/H.265 standard containing Main, Main10, and Main Still Picture profiles. [34] [35] [36] Version 2: (October 29, 2014) Second approved version of the HEVC/H.265 standard which adds 21 range extensions profiles, two scalable extensions profiles, and one multi-view extensions profile.
On March 9, 2015, Nvidia released VDPAU version 1.0 which supports HEVC decoding for the Main, Main 4:4:4, Main Still Picture, Main 10, and Main 12 profiles. [ 110 ] On March 31, 2015, VITEC announced the MGW Ace which was the first 100% hardware-based portable HEVC encoder that provides mobile HEVC encoding.

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 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 ...
Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types of restrictions are intended to simplify the construction of multimedia recorders and players.
