New H.266 / VVC codec will cut video file sizes in half without losing quality

According to analyst estimates, compressed video data today represents up to 80% of all global Internet traffic, and software developers pay close attention to the quality of processing and transmission of “heavy” content on mobile networks. Germany’s Fraunhofer Institute for Telecommunications has introduced a new video encoding standard: according to the developers, it can cut the amount of transmitted data in half without losing image quality.

The codec, whose specification spans more than 500 pages, was created with the popularity of streaming video in 4K and 8K resolutions in mind. It took specialists several years to develop it together with Apple, Ericsson, Intel, HUAWEI, Microsoft, Qualcomm and Sony. The new compression standard is called Versatile Video Coding. It promises to reduce the bit rate and size of video files by about 50% without a noticeable difference in image quality compared to its predecessor (H.265).

H.266 / VVC, according to its creators, makes video transmission on mobile networks more efficient. For example, the old standard requires approximately 10 GB of data to transfer 90 minutes of 4K video, while using the new technology only requires 5 GB of bandwidth. In addition, the codec is suitable for all types of moving images, including 360-degree panoramas and screen capture with live simulcast. Other benefits of H.266 include adaptive resolution switching, as well as support for HDR and 10-bit color depth.

Based on preliminary test results, the efficiency of the new codec turned out to be superior to that of the previously introduced AV1, which was competing with H.265 due to open source code and the lack of a licensing system. Additionally, H.266 has shown significant bitrate savings compared to HEVC, especially when it comes to 4K content. The first software solutions capable of taking advantage of VVC encoding and decoding are expected to appear this fall.

New H.266 codec – same quality, half the file size

Fraunhofer’s company HHI, which created the H.264 and H.265 video codecs, without which today it is difficult to imagine the production of video content, has introduced an updated video encoding algorithm: H.266. The company didn’t get smart with the names and just added one, but under the hood we’re waiting for changes that they’ve been asking for for a long time, that is, the new codec provides half the amount of data while maintaining image quality. at the level of previous codecs.

Video resolution and bitrate are growing day by day, today you will not surprise anyone, for example, with the ability to shoot 4K, rather you will surprise with the absence of such a mode, 8K is on the way, and then scary Think about it, since terabytes of data snowballs, you only have time to swap out the hard drives …

The image does not demonstrate the capabilities of the codec, just an image for a change 🙂

The industry needs a new video encoding algorithm and the H.266 codec came in handy. This algorithm is also called Versatile Video Coding (VVC), that is, a universal video codec. The new standard provides improved compression, reducing the amount of data by approximately 50% while increasing the data transfer rate by the same amount as the previous H.265 (HEVC) standard. Most importantly, without sacrificing image quality.

The H.266 / VVC codec allows you to work with video in all resolutions, from SD and HD up to 4K and 8K, it supports video with high dynamic range and omni-directional 360 ° video, which, although in small steps, continues to gain popularity among users.

Fraunhofer HHI spent more than three years working on the codec, and the description of the H.266 / VVC standard has more than 500 pages of small text, and industry monsters like Microsoft, Apple, Sony, and Intel participated in the work. Benjamin Bross, director of Video Coding Systems, called the launch of the new codec a “quantum leap in encoding efficiency.”

In its press release, Fraunhofer HHI says that while a 90-minute video encoded in H.265 / HEVC is about 10GB, the same video with the new codec will only take up 5GB, and this is the same image quality. “Since H.266 / VVC was designed with ultra-high definition video content in mind, the new standard is especially useful for 4K and 8K video transmission,” the press release says. Also, the codec will support all formats from 480p onwards.

Some experts predict the imminent decline of the era of dominance of the JPEG standard for photographs. So the HEIF image compression format, which Apple implemented on the iPhone, is based on the H.265 / HEVC codec and is used, for example, in the new Canon 1D X Mark III SLR camera. In the same way, the widespread adoption of the H.266 / VVC codec may well lead to the popularization of the “VIC” format for photographs.

The H.265 (HEVC) standard has started to gain popularity recently, and the main problem of its use was quickly clarified: the amount of data that needs to be transferred in some way, stored somewhere, and processed in some multi-core processor systems. Processor and storage manufacturers are, of course, delighted, but the introduction of the new format is quite timely, obvious, and expected by many users and developers alike.

The implementation process itself depends on the hardware manufacturers that could record data using the new codec and on the software manufacturers that could process this highly recorded data. Experts predict the emergence of a new codec by the end of 2020. This process can be greatly accelerated, as recently online streaming has gained particular popularity, and no one will refuse to stream high-quality, high-bit-rate videos, for example, 8K or 4K, and at high speed.

H.266 / VVC video format introduced: same quality as H.265 / HEVC when compressed 2x

The Fraunhofer Institute for Integrated Circuits in Germany, which developed the popular MP3 (MPEG-1 Layer 3) audio encoding format, as well as AVC and HEVC, announced a new video compression format: H.266 / VVC, or Encoding. versatile video player. Someday it should completely replace the current H.265 / HEVC.

The new H.266 claims twice the video stream compression efficiency with the same level of quality as H.265. As noted in the institute, in the case of 90 minute 4K video when using the H.265 / HEVC codec, approximately 10GB of data will need to be transferred, while H.266 / VVC provides identical video quality with half the volume of data.

“By reducing the [volume of] data requirements, H.266 / VVC makes video transmission on mobile networks (with limited traffic) more efficient. For example, the H.265 / HEVC standard above requires approximately 10GB of data for 90 minutes of recording in UHD resolution. The new H.266 / VVC will require only 5 GB while maintaining the same quality, ”said the Institute.

The Institute highlights that the new standard has been developed specifically for 4K (3840 × 2160) and 8K (7680 × 4320) ultra-high definition video, and is especially suitable for transmitting the corresponding signal to flat-screen televisions. The Institute also calls H.266 / VVC the “ideal solution” for all types of moving images, from high-resolution 360-degree panoramic images to screen sharing.

The most widely used codec now is H.264 / AVC, although the H.265 / HEVC standard has been around for quite some time. To avoid previous licensing problems, the developers will authorize the use of the new standard under FRAND (fair, reasonable and non-discriminatory terms), which the Media Coding Industry Forum (MC-IF) will enforce. The first VVC-compliant encoding program will be released in the fall. Hopefully the new H.266 / VVC will not follow the same fate as H.265 / HEVC and will be accepted by the market faster.
