2. Lossy compression - Wikipedia

   en.wikipedia.org/wiki/Lossy_compression

   The compression ratio (that is, the size of the compressed file compared to that of the uncompressed file) of lossy video codecs is nearly always far superior to that of the audio and still-image equivalents. Video can be compressed immensely (e.g., 100:1) with little visible quality loss

3. High Efficiency Video Coding - Wikipedia

   en.wikipedia.org/wiki/High_Efficiency_Video_Coding

   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 same level of video quality ...

4. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/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-measurement issues become important.

5. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   For example, in that model, a zip file's compressed size includes both the zip file and the unzipping software, since you can not unzip it without both, but there may be an even smaller combined form. Examples of AI-powered audio/video compression software include NVIDIA Maxine, AIVC. [23]

6. 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 ...

7. 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] Much like the H.26x and MPEG standards, the ProRes family of ...
