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 [update] was at version 15. [ 1 ]
WebP's lossy compression algorithm is based on the intra-frame coding of the VP8 video format [24] and the Resource Interchange File Format (RIFF) as a container format. [4] As such, it is a block-based transformation scheme with eight bits of color depth and a luminance–chrominance model with chroma subsampling by a ratio of 1:2 (YCbCr 4:2:0 ...
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.
The DCT, which is fundamental to modern video compression, [73] was introduced by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974. [17] [74] H.261, which debuted in 1988, commercially introduced the prevalent basic architecture of video compression technology. [75] It was the first video coding format based on DCT compression. [73]
JPEG XS is a light-weight compression that visually preserves the quality compared to an uncompressed stream, at a low cost, targeted at compression ratios of up to 10:1. With XS, it is for example possible to repurpose existing SDI cables to transport 4K60 over a single 3G-SDI (at 4:1), and even over a single HD-SDI (at 8:1).

Bink uses a wavelet-based compression algorithm optimized for game video sequences. It supports resolutions up to 4K and can encode at bitrates from 500 kbps to 200 Mbps. The codec is designed for efficient decompression, leveraging multithreading and SIMD instructions on modern CPUs.
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.
