    en.wikipedia.org/wiki/Versatile_Video_Coding

    Versatile Video Coding (VVC), also known as H.266, [1] ISO/IEC 23090-3, [2] and MPEG-I Part 3, is a video compression standard finalized on 6 July 2020, by the Joint Video Experts Team (JVET) [3] of the VCEG working group of ITU-T Study Group 16 and the MPEG working group of ISO/IEC JTC 1/SC 29.

  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. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    Video compression algorithms attempt to reduce redundancy and store information more compactly. Most video compression formats and codecs exploit both spatial and temporal redundancy (e.g. through difference coding with motion compensation). Similarities can be encoded by only storing differences between e.g. temporally adjacent frames (inter ...

  5. Apple ProRes - Wikipedia

    en.wikipedia.org/wiki/Apple_ProRes

    Apple ProRes is a high quality, "visually lossless" lossy video compression format developed by Apple Inc. for use in post-production that supports video resolution up to 8K.It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. [1]

  6. H.261 - Wikipedia

    en.wikipedia.org/wiki/H.261

    H.261 is an ITU-T video compression standard, first ratified in November 1988. [1] [2] It is the first member of the H.26x family of video coding standards in the domain of the ITU-T Study Group 16 Video Coding Experts Group (VCEG, then Specialists Group on Coding for Visual Telephony).

  7. 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.

  8. Comparison of video codecs - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...

  9. DV (video format) - Wikipedia

    en.wikipedia.org/wiki/DV_(video_format)

    DV-DIF is the raw form of DV video. The files usually have extensions *.dv or *.dif. DV-AVI is Microsoft's implementation of DV video file, which is wrapped into an AVI container. Two variants of wrapping are available: with Type 1 the multiplexed audio and video is saved into the video section of a single AVI file, with Type 2 video and audio ...
