2. Comparison of video codecs - Wikipedia

   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.

3. Video coding format - Wikipedia

   en.wikipedia.org/wiki/Video_coding_format

   A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .

4. VP8 - Wikipedia

   en.wikipedia.org/wiki/Vp8

   VP8 is a traditional block-based transform coding format. It has much in common with H.264, e.g. some prediction modes. [8] At the time of first presentation of VP8, according to On2 the in-loop filter [9] and the Golden Frames [10] were among the novelties of this iteration.

5. Video codec - Wikipedia

   en.wikipedia.org/wiki/Video_codec

   A short video explaining the concept of video codecs. A video codec is software or hardware that compresses and decompresses digital video.In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.

6. Video compression picture types - Wikipedia

   en.wikipedia.org/wiki/Video_compression_picture...

   Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame ( intra-coded picture ) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame.

7. x265 - Wikipedia

   en.wikipedia.org/wiki/X265

   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 ...

   iLBC – Low bitrate compression, primarily voice; iSAC – Low bitrate compression, primarily voice; (free when using the WebRTC codebase) TTA – Lossless compression; WavPack – Hybrid lossy/lossless; Bonk – Hybrid lossy/lossless; supported by fre:ac (formerly BonkEnc) Apple Lossless – Lossless compression (MP4)

9. Dirac (video compression format) - Wikipedia

   en.wikipedia.org/wiki/Dirac_(video_compression...

   Dirac (and Dirac Pro, a subset standardised as SMPTE VC-2) is an open and royalty-free video compression format, specification and software video codec developed by BBC Research & Development. [4] [5] [6] Dirac aimed to provide high-quality video compression for Ultra HDTV and competed with existing formats such as H.264. [3]
