New Viable Video Codecs on the Way? Maybe

VVC isn’t far enough along in its development to properly assess its practicality as a next-generation MPEG codec. One of its developers, Fraunhofer, says the technology has gained 30-35 percent improved efficiency over HEVC with an eventual target of 50 percent. A finalized standard is due sometime in 2020. On the licensing side, observers say VVC will not be free, but anything beyond this eventuality is pure guesswork.

There are some caveats cloud MPEG-5/EVC, however:
1.EVC will not deliver as much efficiency over HEVC as VVC promises.
2.What IP will be used and what royalty rates for the EVC main profile will be are not known.
3.MPEG-VCEG (Video Coding Experts Group) is working with VVC, not EVC.
