MPEG / ITU-T successor to HEVC/H.265 is called Versatile Video Coding (VVC)

The Joint Video Experts Team (JVET), a collaborative team formed by MPEG and ITU-T Study Group 16's VCEG commenced work on a new video coding standard to be known as Versatile Video Coding (VVC) at this meeting. The primary objective of VVC is to provide a significant improvement in compression performance over the existing HEVC standard, aiding in deployment of higher-quality video services and emerging applications such as 360° omnidirectional immersive multimedia and high-dynamic-range (HDR) video. The development of the VVC standard is expected to be completed in 2020. The two bodies issued a joint Call for Proposals, and the responses were evaluated at the San Diego meeting. Responses to the call were received from 32 organizations, with some demonstrating compression efficiency gains of typically 40% or more when compared to using HEVC. The gain was measured in extensive formal subjective tests conducted by independent test labs. Both 360° omnidirectional video and HDR video were tested as well as conventional dynamic range video. Particular effectiveness was shown on ultra-high definition (UHD) video test material. The results of this very successful call led to creation of a first draft, a test model for simulation experiments, and a technology benchmark set for the VVC project. The new standard is expected to enable the delivery of UHD services at bit rates that today are used to carry HDTV. Alternatively, using VVC would enable twice as much video content to be stored on a server or sent through a streaming service

NGCodec Quote in Amazon Press Release on the new F1 instance announcement

“Cloud video encoding is exploding, but traditional software approaches need massive CPU resources and cannot deliver the video quality and latency necessitated by new applications. We have developed a next generation video encoder that, using FPGA hardware acceleration, offers low latency and low cost while maximizing video quality to keep up with today’s broadcasting standards,” said Oliver Gunasekara, Chief Executive Officer and co-founder, NGCodec. “AWS is the first cloud provider to add FPGA instances, which provide massive acceleration. In just three weeks, we ported our RealityCodec™ H.265/HEVC encoder to the new F1 instance type to enable AWS Cloud customers to leverage the benefits of higher video quality, lower latency, and lower cost for live H.265/HEVC video encoding. Updating our install base globally will be as simple as publishing a new Amazon FPGA image and re-launching F1 instances.”
