  2. JPEGmini - Wikipedia

    en.wikipedia.org/wiki/JPEGmini

    JPEGmini technology is built around a perceptually aligned image quality measure, which reliably determines the maximum amount of compression which can be applied to each individual image or video frame without introducing visible artifacts. This engine does the image transformation and generates an output that complies with all standards when ...

  3. Lossless compression - Wikipedia

    en.wikipedia.org/wiki/Lossless_compression

    Lossless compression. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only ...

  4. Display Stream Compression - Wikipedia

    en.wikipedia.org/wiki/Display_Stream_Compression

    Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1] It is a low-latency algorithm based on delta PCM coding and YC G C O-R color space. [1] [2]

    HEVC / H.265 / MPEG-H Part 2. High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the ...

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats. The compression may employ lossy data compression, so that quality ...

  7. MPEG-1 - Wikipedia

    en.wikipedia.org/wiki/MPEG-1

    MPEG-1 is a standard for lossy compression of video and audio.It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.

  8. Video file format - Wikipedia

    en.wikipedia.org/wiki/Video_file_format

    Video file format. A video file format is a type of file format for storing digital video data on a computer system. 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 ...

  9. 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; however ...
