formed the Joint Video Exploration Team (JVET) to evaluate available compression technologies and study the requirements for a next-generation video compression standard. The new standard has about 50% better compression rate for the same perceptual quality, with support for lossless and subjectively lossless compression. It supports resolutions ranging from very low resolution up to 4K and 16K as well as 360° videos. VVC supports

is expected, depending on the quality of the encoding algorithm (which is outside the scope of the standard). The decoding complexity is about twice that of HEVC. VVC development has been made using the VVC Test Model (VTM), a reference software codebase that was started with a minimal set of coding tools. Further coding tools have been added after being tested in Core Experiments (CEs). Its predecessor was the Joint Exploration Model (JEM), an experimental software codebase that was based on the reference software used for

History

JVET issued a final Call for Proposals in October 2017, and the standardization process officially began in April 2018 when the first working draft of the standard was produced. At

2018, a preliminary implementation based on VVC was demonstrated that was said to compress video 40% more efficiently than HEVC. The content of the final standard was approved on 6 July 2020.

implementations, for VVC a new group called the Media Coding Industry Forum (MC-IF) was founded. However, MC-IF had no power over the standardization process, which was based on technical merit as determined by consensus decisions of JVET. Four companies were initially vying to be patent pool administrators for VVC, in a situation similar to the previous AVC and HEVC codecs. Two companies were later reported to be forming pools: Access Advance and
