H.266 also known as VVC (Versatile Video Coding) - is a standard of efficient video compression developed by the Joint Video Experts Team (JVET), MPEG group, and VCEG.
The first codec was introduced by Fraunhofer HHI in July 2020.
The standard should support frame resolution up to 16K, chroma subsampling 4:4:4, 4:2:2, and 4:2:0, bit depth from 8 to 16 bit per pixel, high dynamic range (HDR) with more than 16 bits per pixel. Estimated encoding complexity up to 10 times higher than H.264 while provides 30-50% bitrate saving. On the other side, decoding complexity is about 2 times higher.
