   en.wikipedia.org/wiki/RealVideo

   RealVideo, also spelled as Real Video, is a suite of proprietary video compression formats developed by RealNetworks — the specific format changes with the version. It was first released in 1997 and as of 2024 was at version 15. [1] RealVideo is supported on many platforms, including Windows, Mac, Linux, Solaris, and several mobile phones.

   Of course, future-LZ compression requires 2 passes over input file but decompression needs tiny memory. [citation needed] In one experiment, 22 GB file compressed with minimum match length of 512 bytes and full 22 GB dictionary required just 2 GB of RAM for decompression. [citation needed]

4. Comparison of video codecs - Wikipedia

   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 ...

5. Uncompressed video - Wikipedia

   en.wikipedia.org/wiki/Uncompressed_video

   Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.

   VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008. Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies. Google provided an irrevocable patent promise on its patents for ...

8. HandBrake - Wikipedia

   en.wikipedia.org/wiki/HandBrake

   HandBrake's backend contains comparatively little original code; the program is an integration of many third-party audio and video libraries, both codecs (such as FFmpeg, x264, and x265) and other components such as video deinterlacers (referred to as "filters").

9. Dirac (video compression format) - Wikipedia

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

   Dirac supports resolutions of HDTV (1920×1080) and greater, and is claimed to provide significant savings in data rate and improvements in quality over video compression formats such as MPEG-2 Part 2, MPEG-4 Part 2 and its competitors such as Theora and WMV. Dirac's implementers made a preliminary claim of "a two-fold reduction in bit rate ...
