  2. High Efficiency Video Coding tiers and levels - Wikipedia

    en.wikipedia.org/wiki/High_Efficiency_Video...

    The HEVC standard defines two tiers: Main and High. [1] [2] The Main tier is a lower tier than the High tier. [1] [2] The tiers were made to deal with applications that differ in terms of their maximum bit rate. [1] The Main tier was designed for most applications while the High tier was designed for very demanding applications. [1]

    High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10).

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    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.

    In high bitrate encodings, the content payload is usually large enough to make the overhead data relatively insignificant, but in low bitrate encodings, the inefficiency of the overhead can significantly affect the resulting file size if the container uses large stream packet headers or a large number of packets.

    The tests also showed that it took 60% longer to decode HEVC video encoded at 16×16 CTU size than at 64×64 CTU size. [2] The tests showed that large CTU sizes increase coding efficiency while also reducing decoding time. [2] The tests were conducted with the Main profile of HEVC based on equal PSNR. [2]
