List of video codecs

from Wikipedia, the free encyclopedia

Video codecs are required to provide digital video data for certain applications andto store itin a container file . Some of the programs listed are actually not codecs, as either the encoder (encode / compress) or the decoder (decode / decompress) are missing. Nevertheless, they are usually subsumed under the term codec.

Lossy video codecs

The compression of the video information considerably reduces the need for transmission capacity or storage space ; for this purpose, the video information is simplified and combined with compression algorithms . However, less important information is also discarded.

MPEG video codecs

  • MPEG-1 Part 2 (ISO 11172): typical use: Video CD (VCD) and MPEG-2 Part 2 (ISO 13818) or H.262: 8 bit color depth, 4: 2: 0 color subsampling, restriction to 25 Mbps Data transfer rate, typical uses are: SuperVideo-CD (SVCD) , MVCD , KVCD , DVD , DVB , HDTV

Lossless video codecs

Lossless video codecs retain their original quality. They work without lossy compression and therefore usually require more storage space.

  • Ben Rudiak-Gould HuffYUV : under a free GNU General Public License
    • FFmpeg (both an implementation of the original codec and an advancement)
  • CoreCodec / Jory Stone CorePNG : under free GNU General Public License
  • LCL codec
