  2. Comparison of video container formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_video...

    Overhead is affected by the total number of packets and by the size of stream packet headers. 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 ...

  3. 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.

  4. Video file format - Wikipedia

    en.wikipedia.org/wiki/Video_file_format

    Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9) alongside audio data in an audio coding format (e.g. Opus).

  5. 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 .

    en.wikipedia.org/wiki/Audio_Video_Interleave

    Audio Video Interleave (also Audio Video Interleaved and known by its initials and filename extension AVI, usually pronounced / ˌ eɪ. v iː ˈ aɪ / [3]) is a proprietary multimedia container format and Windows standard [4] introduced by Microsoft in November 1992 as part of its Video for Windows software.

  7. FFV1 - Wikipedia

    en.wikipedia.org/wiki/FFV1

    This can be useful for compression due to the very large size of the context table, but can be disabled to force the encoder to generate a strictly intra-frame bitstream. As the gained compression seems to decrease [65] with later versions of FFV1 (version 2,3), the use of GOP size greater than "1" might disappear in the future.
