H.266 Video Codec VVC 50% smaller compared to h.265 at the same quality
Fraunhofer issued a press release that is making a pretty interesting claim, as the h.265 video of yours, can be halved in size, at the same quality. Fraunhofer's successor to H.265/HEVC for encoding would be H.266, also referred to as Versatile Video Coding (VVC) and offers significant improvements.

After devoting several years to its research and standardization, Fraunhofer HHI (together with partners from industry including Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm, and Sony) is celebrating the release and official adoption of the new global video coding standard H.266/Versatile Video Coding (VVC). This new standard offers improved compression, which reduces data requirements by around 50% of the bit rate relative to the previous standard H.265/High Efficiency Video Coding (HEVC) without compromising visual quality. In other words, H.266/VVC offers faster video transmission for equal perceptual quality. Overall, H.266/VVC provides efficient transmission and storage of all video resolutions from SD to HD up to 4K and 8K, while supporting high dynamic range video and omnidirectional 360° video.
Today, compressed video data make up 80% of global Internet traffic. H.266/VVC represents the pinnacle of (at least) four generations of international standards for video coding. The previous standards H.264/Advanced Video Coding (AVC) and H.265/HEVC, which were produced with substantial contributions from Fraunhofer HHI, remain active in more than 10 billion end devices, processing over 90% of the total global volume of video bits. Both previous standards were also recognized by collectively three Emmy Engineering Awards for contributing substantially to the progress of television technology.
Through a reduction of data requirements, H.266/VVC makes video transmission in mobile networks (where data capacity is limited) more efficient. For instance, the previous standard H.265/HEVC requires ca. 10 gigabytes of data to transmit a 90-min UHD video. With this new technology, only 5 gigabytes of data are required to achieve the same quality. Because H.266/VVC was developed with ultra-high-resolution video content in mind, the new standard is particularly beneficial when streaming 4K or 8K videos on a flat screen TV. Furthermore, H.266/VVC is ideal for all types of moving images: from high-resolution 360° video panoramas to screen sharing contents.
“After dedicating almost three years toward this standard, we are proud to have been instrumental in developing H.266/VVC," says Benjamin Bross, head of the Video Coding Systems group at Fraunhofer HHI and editor of the +500-page standard specification of H.266/VVC. “Because of the quantum leap in coding efficiency offered by H.266/VVC, the use of video will increase further worldwide. Moreover, the increased versatility of H.266/VVC makes its use more attractive for a broader range of applications related to the transmission and storage of video.”
"If you consider that Fraunhofer HHI already played a key role in the development of the previous video coding standards H.264/AVC and H.265/HEVC, then we are happy with the fact that more than 50% of the bits on the Internet are generated by a Fraunhofer HHI technology,” adds Dr. Detlev Marpe, head of the Video Coding and Analytics department at Fraunhofer HHI.
A uniform and transparent licensing model based on the FRAND principle (i.e., fair, reasonable, and non-discriminatory) is planned to be established for the use of standard essential patents related to H.266/VVC. For this purpose, the Media Coding Industry Forum (MC-IF) was founded. In addition to Fraunhofer Society, the MC-IF now includes +30 companies and organizations. The new chips required for the use of H.266/VVC, such as those in mobile devices, are currently being designed. Dr. Thomas Schierl, head of the Video Coding and Analytics department at Fraunhofer HHI, announced “this autumn Fraunhofer HHI will publish the first software (for both encoder and decoder) to support H.266/VVC.”

Sure but the silicon travel from the factory to your house ONCE, while the data travel every day.
I'm skeptical about same identical quality, probably on some particular test video.
I can understand how going up on 8k, on normal video content there is space for a lot of optimization, but i can't believe you can get to 1080p half size and same quality.

How are "same quality" defined? In my view contets transition into more plasticy look for every generation of compression and "intelligent" image enhancements. Espescialy annoying for fine details like grass, trees, skin, fur, hair, textiles and dirt. Mad Max wont be the same with plastic treatment.

I am still waiting for decent HEVC encoder for high-quality BD rips that doesn't take ages.. Post AVC codecs improvements looks like in real life only for low-quality content due bad encoders. Yes, yes HEVC is a must for proper HDR content, but encoders are still terrible for HQ rips and speed...

as soon as your encoder speed goes double the video fps, they manage to bring it down to half again lol they must love slow encoding (joking)
good news I guess for bandwith, not so for nature as my H.265 encoding experiences meant having a nuclear power plant at home

You make the footprint smaller but you increase the footprint of the silicon required to decode it.
