Sep 20, 2018 · HEVC (H.265) vs. AVC (H.264) - What’s the Difference? BoxCast • September 20, 2018. This post talks about the differences in H.265 and H.264 video compression. It's part of our series on video encoders. We’ve all been there. Apr 23, 2018 · Facebook said in recent tests that AV1 surpasses its stated goal of 30% better compression than VP9, and achieved gains of 50.3%, 46.2% and 34.0%, compared to x264 main profile, x264 high profile and libvpx-vp9, respectively. But it also said AV1 requires longer encoding times vs. current alternatives due to increased complexity. NVENC on Pascal or Maxwell in HEVC is a decent solution if you are encoding offline. If you have tonnes of video to process and bandwidth is not a major concern then this is for you. The H.265/HEVC results are competitive with x265 in bitrate abundance. Maxwell 2nd gen (NVENC 3rd gen) is about 2.5x faster than a stock i7-8086k at 100% CPU usage. AV1 quality comparison. AV1 delivers superior quality at significantly lower bitrates when compared to HEVC, VP9 and H.264. Our tests and evaluations have show that AV1 outperforms all the other codecs when encoded with the same bitrate settings. May 15, 2017 · Google’s Royalty-Free Answer to HEVC: A Look at AV1 and the Future of Video Codecs. Almost 5 years ago Google first released VP9, the royalty free video codec that aimed to replace H.264 as the ... In comparison of HEVC vs. VP9 we can assign a pair (impact on coding efficiency, impact on complexity) to each feature. For instance for intra modes feature the pair is ( + , - ) meaning coding efficiency of HEVC imporved against VP9 and complexity (processing time of HEVC) is reduced against VP9. Recently HEVC adoption has increased, but it is still not supported by many browsers and only has hardware support on newer mobile devices. AV1. Essentially AV1 is a format developed by the AOMedia consortium and is open and royalty-free. Early tests have shown that AV1 can compress videos more efficiently than even HEVC, by up to 30%. HEVC has a clear advantage in exploitation of different directions of spatial redundancy vs. VP9. Moreover, the planar mode of HEVC is much effective than the corresponding TrueMotion mode of VP9. However, this does come with a possible complexity penalty in HEVC for mode selection. Below-Left Intra Predictors In our tests, AV1 takes approximately 160-190x more time than x264 to encode in their lossless mode. AV1 does have a lossless mode, but the output is not lossless at all. VP9 and AV1 can take advantage of multi-threading, but they can not load all CPU cores all the time as x264 and x265 do. subsequent development of VP9 • Given that VP9 was never highly utilized and is about to be supplanted, an infringement suit seems unlikely • That said, an AV1 suit would probably include VP9 as well • Same storage costs at origin as HEVC The AV1 results were derived by the institute using the AOMedia reference codec. The measurements on the VP9 and HEVC codecs were performed by Bitmovin’s encoding platform, which employed the generic implementation of the MPEG codecs known as ffmpeg as an apples-to-apples comparison with the generic AV1 reference codec. NVENC on Pascal or Maxwell in HEVC is a decent solution if you are encoding offline. If you have tonnes of video to process and bandwidth is not a major concern then this is for you. The H.265/HEVC results are competitive with x265 in bitrate abundance. Maxwell 2nd gen (NVENC 3rd gen) is about 2.5x faster than a stock i7-8086k at 100% CPU usage. subsequent development of VP9 • Given that VP9 was never highly utilized and is about to be supplanted, an infringement suit seems unlikely • That said, an AV1 suit would probably include VP9 as well • Same storage costs at origin as HEVC By contrast, VP9 is more challenging in MTU-matching, ultra low-delay modes, parallelization. 3. H.265 vs AV1. AV1(AOMedia Video1), is an open, royalty-free video coding format designed for video transmission over the Internet and is the successor to VP9. Nowadays, Netflix, Facebook and YouTube ect. are adopting AV1 to compress streaming contents. VP9 and AV1 use golden frames, which means every Nth frame has much higher quality than the rest of them. So looking at individual frames can be misleading, because if you're looking at golden frames, or a few frames after them, the quality is much higher than the average quality of the video. x264 and x265 doesn't cheat like that, not to mention golden frames introduce a rather annoying ... The next-generation HEVC/H.265 codec, wit h its many patents, could cost up to ten times more than AVC/H.264. Where did AV1 come from? During the last six years, a number of companies launched projects to create viable alternatives to patented video codecs. Mozilla started work on the Daala Project, Google released VP9, May 30, 2019 · The graph below shows the average bit rates a compressed video of equal quality would have if encoded with AV1 or VVC relative to HEVC. ...

The AL-E210 supports, aside from VP9, H.265/HEVC, H.264/AVC and JPEG, the AV1 Main profile, with which it can encode 4:2:0 Chroma subsampling with 8 and 10 bit color depth. A single core can encode 4K with 30 fps, with multiple cores that should even be higher. Simpler CPUs that are brand new in 2019 may cope quite well with codecs from 15 years ago. But then they suffer drastically with the more recent codecs like VP9 and AV1. Just because your brand new 9900k smashes x264 encoding does not mean it can cope with libvpx-vp9 at all. HEVC has a clear advantage in exploitation of different directions of spatial redundancy vs. VP9. Moreover, the planar mode of HEVC is much effective than the corresponding TrueMotion mode of VP9. However, this does come with a possible complexity penalty in HEVC for mode selection.

On paper AV1 seems like a much more attractive option to HEVC. It is open-source and royalty-free, provides better compression, and has the backing of the powerful AOMedia consortium that created it. However much of AV1’s potential is still unproven, and there is still a lot of uncertainty surrounding it. Jul 30, 2019 · Is HEVC Ready For The MAINSTREAM? | HEVC Vs. VP9 Vs.
