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.

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 is relatively good since they are not re-encoded ("untouched" releases). The video (H.264 or H.265) and audio (AC3/AAC) streams are usually extracted from iTunes or Amazon Video and remuxed into a MKV container without sacrificing quality. An advantage with these releases is that, like BD/DVDRips, they usually have no onscreen ...

Botswana's TV and mobile- segment terrestrial broadcast services of ISDB-T uses the H.264/AVC codec, including major broadcaster such as Botswana Television. Brazil's terrestrial broadcast service uses H.264/AVC in ISDB-T. Colombia announced in August 2008 the adoption of the DVB-T broadcasting standard.

In the comparison, the HM-15.0 HEVC encoder had the highest coding efficiency and, on average, for the same subjective quality the bit rate could be reduced by 49.4% compared with the VP9 1.2.0–5183 encoder, and it could be reduced by 52.6% compared with the JM-18.8 H.264/MPEG-4 AVC encoder.
