Fantastic. FB, RU-vid, Netflix, Google are all playing with some AV1 in some way. The real savings are about $$$. But the HEVC/HEIC was weighed down completely by the licensing fiasco. And just as AV1 is getting wider adoption, far in the background AV2 is being worked on. Far away, but experiments are abound. Great video 👍🏾.
if you need to use if or if MP4 then AV1 is a dud. although of course, the ideal is to force the environment to use AV1 (under a container like mkv, which is confusing)
Superb explanation with crisp value and no BS. A question tho, what is H264's licensing model? If it's also fraunhofer product how did it become it so popular?
The H.266, AV1, MPEG-5 aren't completely out yet. There are no fully optimized encoders with all the implemented features, there are no datasets to compare efficiencies. RU-vidrs meanwhile: H.266 will reduce the size by 50%, while AV1 only promises 30-40%. That's not how compression works. Different videos will compress differently and in different cases different codecs will perform better. Think of 2D animation vs Cinema, 3D animation vs Stop motion, Minecraft videos vs Game of life automatas. All of those types of video will perform differently with different codecs and settings. So until the encoders mature and reliable tests are out, you can't just say: "H.266 is more efficient" just because JVET said so. Sorry for ranting. Otherwise your video is good and informative, but jumping to conclusions is a bad habit IMO.
@@Channel8eight True, but you could keep the previews short and focus on talking what you noticed in each one and how they compare. It's better to trust your word than look for differences ourselves with RU-vid compression in-between. However, it'd be a good idea if you offered download links to all the different results.
The best one is H264 as that already works everywhere. Only big video service providers and ISPs care about a 20% compression improvement for the exact same end user experience. Hoping that at least don't make us pay for it (so AV1 please!)
@@balloonsystems8778 AV1 has a 30-50% compression efficiency improvement in relation to H.265, not H.264. Compared to H.264, the savings for AV1 are even bigger. For me the codec of the future definitely will be AV1.
I'm not seeing h266 in any way more compelling compared to AV1. For 10% more efficiency compared to AV1 that also costs you a lot of money as a company for licensing I can only see AV1 as going forward.
I think look at where we are at not can help. RU-vid uses the free VP9 and most UHD Blu Rays are HEVC. I believe even before it was like this as many BLu rays are in AVC.
Ah, noticed the South African accent. I like how you’re South African, but not a stereotype i.t.o. your mannerisms etc. - guessing you’re an expat. Anyway your format, presentation and persona are outstanding. Subbed. Good luck to you.
A very educational video! Thanks! I didn't even know these things existed, I only knew about H.264 and H.265. So when can I stream at 8K @ 240 Hz at Twitch? Just kidding, that's probably a decade away :-D
You said that H.266 gives **UP TO 50%** lower bandwidth over H.265. But you gave it a blue bar instead of yellow in the graph at 6:46 like you did with AV1, this makes a graph misleading, not going to lie...
The crazy thing about it is h264 is capable of *much* more than it's given credit for. I've been playing with video since MPEG2 days, if you tune h264 you can get similar quality and file size as h265. h265 doesn't really begin to shine until you're looking at 4K videos, 1080P and below work better on h264. You can get nearly perfect video quality with h264 with a 1250Kbps bitrate at 1080P.
@@flirtationdance I've got a pretty good preset for h264 that will do 550Kbps for 480P and 750Kbps for 720P, not a constant bitrate so it does occasionally spike to ~3Mbps but most shows do fine, games on the other hand... lol
Latest generation of intel, amd and nvidia gpus support av1 hardware decode yet no video encoder or websites like youtube support uploading in av1 codec. its been 3 years since the release yet still nothing.
The standard H265 codec is actually quite trash.. Better than H264 for sure, but it still has issues with color banding and it really doesn't look good when pushed to the extreme. The only viable way to compress footage reliably these days is by using 2-pass H265 10bit encoding with 50% original bitrate compared to the source file or no less than 3mbps for 1080p 24fps stream when encoding with medium preset. My results are excellent, although it does take roughly 6 times as long to encode compared to a standard H264. And if the original file has an obscenely high bitrate, you don't wanna compress it too much because the little details are the first to go.
With the advent of "deepfake" video and video manipulation is it not time for Digital Video Signatures and who would ultimately be responsible in implementing this?
Oh Netflix uses AV1 ? I thought it is still under development by Google, microsoft, Amazon prime, Netflix , and others. Thanks for the info. Please add VP9 too.
@Johan V - I think you have got that entirely the wrong way around. "AV1 for p!rates?" Not a chance. Such people don't care about such licencing 'fees' (if they're already prepared to do what they do), since they will simply use whatever codec they wish to, without paying any fees. Just look at the current 'scene' no p!rates use VP9 for their elite quality encodes, it's 'all' dominated by the best performing codec, which happens to be HEVC. No doubt AV1 may become popular with official streaming organisations that care about the savings they could make that they would otherwise be legally obliged to pay the licences and fees for. But the 'underground scene' will always go for whichever codec performs better and is widely supported, which apparently following the current trend of the popular HEVC/h.265 will be VVC/h.266. They will simply ignore such fees just as they currently do (and always have done).
It would actually be the opposite dude. If 266 is better than AV1 but for the license, who doesn’t pay for licenses? The pirates. Here’s a good example its easier to find an h.265 torrent for something than to find it on most streaming sties.
Because of HUGE licensing issues, H.265 is not used at all with the exception of UHD Blurays. With the H.266 I am afraid it will be the same. VP9 as a competitor of H.264 has the same problem like AV1 in comparison with H.265 - at the moment its competitor will get a successor, the royalty free alternative is still too slow for real world applications (H.264 encoding = hundreds FPS with hardware codecs or tens with the most exhaustive settings of software codecs, VP9 nowhere near with HW implementations completely missing; H.265 is about one half of the H.264 speed but its competitor AV1 has horrible encoding rate often lower than 1 fps with only 1080p source so it is completely unusable). VP9/AV1 support by editing software is close to zero. Even lossless H.264 is still not supported almost at all and even for 4:2:2 quantization I usually need some upgrades from standard versions of the software.
@@tulenik71 the cpu is not the one responsible for hardware encode/decode. Its the gpu. Nvidia ampere, amd rdna 2 and intel xe grphics all support av1 decode.
@@tulenik71 Intel Arc Alchemist series now supports hardware AV1 encoding, and results are really promising, and being able to encode in realtime without much performance loss! Nvidia and AMD will support it soon too. So AV1 is indeed going to be widely adopted unlike what you said.
@@balloonsystems8778 As far as I know, EVC is being made as an alternative to H.266 and and HEVC in case if the licensing issue is not resolved. That's why EVC has a baseline profile which contains only free tools and is 30% more efficient than H.264. Whereas the main profile is paid and contains premium tools, properly licenced and provides 25% efficiency over HEVC.
