HEVC and AV1 play the leading role in efficient HD/UHD video coding.

Vc1 codec 1080p#

It even exceeds H.266 when dealing with 1080p HD or lower-resolution videos.įor example. Generally, VVC is superior to AV1 in terms of video coding efficiency, but AV1 is not really far behind. Things are a little different from sequence to sequence.

Roughly speaking, the higher the resolution is, the more bit rate VVC saves.Īctually, there are far more testing data than what we present above.

H.266/VVC optimizes both Intra and Inter video coding algorithms.

A negative BD-rate value means reduction of bit rate at the same quality level.

PSNR, abbreviation of peak signal-to-noise ratio, is widely used as the metric of subjective video quality.

BD-rate is used to evaluate coding efficiency, indicating the changing of bit rate and PSNR.

VTM and SCM are performance test models for H.266, while HM/x265/NVenc 265 for HEVC.

To understand the statistics, you need to know: Check the comparison of video coding efficiency (H.266 vs H.265 vs AV1 vs H.264) below. Then what are the exact bit rate savings of VVC? How long does H.266 take to encode a 4K video? Authorities have made the test for us. What makes the new standard H.266/VVC codec eagerly anticipated is that there is no further tradeoff between file size and quality compared with AV1, HEVC, etc.

Overview of codec 4K HDR support Coding Efficiency - VVC vs HEVC vs AV1

Better support for High Dynamic Range (HDR) and 360° video.

VVC is better for streaming UHD content in 4K, 8K and even 16K on TV.

In terms of quality, H.266 now is the one barely any codec can match at the same file size.

A video file encoded in VVC therefore would be much smaller than in HEVC, let alone in AVC.

H.266 comes with new algorithm, 30% to 50% higher compression rate for the same video quality than HEVC.

The higher the compression ratio, the less the bit rate for data transmission, the smaller the file size would be. Normally, one of the reasons that a new video coding standard is worth spreading is due to the huge improvement of video compression algorithm. What is H.266/VVC codec The Advantages of H.266/VVC are proprietary with numbers of patent pool administrators.

It is designed as the successor to High Efficiency Video Coding (HEVC/H.265) for further alleviating stress on large data transmission like 4K, 8K and even 16K UHD videos, as new codec always has been.Ĭompared with royalty-free video coding formats like AVI and VP9, H.26x series including H.266, H.265, H.264, etc. H.266/VVC is MPEG's next-generation video encoding and decoding standard. 1080p File size raw vs compressed What Is H.266/VVC? When it comes to streaming a second of 4K, the number reaches up to around 6 Gbps. How staggering the average bit rate number would be for transmitting a HD video without compression? For a 1080p 30fps video, it would be 1423.82 Mbps. (Besides encoding videos with such lossy video codecs, there are several other ways for video compression.) As you may imagine, with the advance of video resolution, there might be H.267, H.268, etc in the future for 16K and higher. Video compression standards, especially lossy video codecs like HEVC, H.264, VP9 and AV1, are developed with the intention to cut redundant information without damaging quality much, and ease the burden of bandwidth during data transmission accordingly. The goal of video compression never changes If you need both a simple conclusion of what life-changing impacts H.266 would have and an in-depth analysis of video compression algorithm improvements, you are at the right place. Why do people keep moving forward on video coding formats? What makes H.266 better than H.265, H.264, AV1 or VP9? This codec is intended to be rolled out by the end of 2020.Įverybody talks about H.266/VCC and its 30 to 50 percent higher compression ratio, but not enough people dig into the reasons and details lying beneath the surface.

Versatile Video Coding (hereafter referred to as VVC or H.266) standard was finalized by the Joint Video Experts Team (JVET) on July 6, 2020.
