I am a member in the group for development of AV1. The reason it has taken so long to adopt is because it was only in the last two years that the codec was stabilized to an acceptable enough degree for mass deployment. By the end of 2025 most major platforms should have it fully or partially adopted.
You might not be able to answer but I'm gonna ask anyway. How far off is it? Just a ballpark is enough, you can be as vague as you need to be. Just give us hope. We've been hearing about twitch wanting to implement AV1 for years now, and at this point they might as well contribute to AV2's production or switch to VVC.
could you maybe tell us why it's so expensive on the recording side, if we go to to almost no quality loss of recording? it looks realy freaking good, almost 1-1 from my end to the encoding, but damn is it storage intensive. For reference, i encode in CQP lvl19 or 18 and 30-second to 1min can sometimes be already 1gb of storage.
Another massive benefit over H.264 that AV1 has is the ability to encode HDR footage that is tone-mapped for SDR playback as well. Nvidia recently pushed an update for Shadowplay enabling AV1 and now I’m able to play games in HDR and still clip footage for my friends without it looking like a washed out mess on their screens. When it gets added to Twitch and Discord allows it in their streaming pipeline AV1 is absolutely the future.
What gets me is that I'm getting back into the game after a 3-year+ hiatus, and the same day I decide to get back in thor uploads a short mentioning it.
I got a $100 arc GPU just for hardware encoding AV1, still use my 3080ti as primary GPU. (Also you can do CPU encode/decode for AV1 it just takes longer).
Me too! 6700 XT in my main rig and an a380 in my encoding machine. The nice part is that the Intel h246 hardware encoders also aren't half bad, so I've still been able to use it quite a bit. Funny story, I got my a380 right after the launch in the west and so it wasn't supported in just about anything and it was my first PC because I'm an idiot and make my life harder for no reason. Took me a few weeks to get everything working properly (although using Linux also didn't make my life any easier).
@@DekustahOnly issue is that for live streaming, trying to make your CPU do the video encode can often hamper performance on the rest of the system. If it was encoding video for later playback then yeah I’d say do software encode but hardware acceleration is probably best for livestreams
They actually also convert some assets to AV1 and store them on their servers. When an asset is encountered, it checks the servers, and if it doesn't find it, it uses a placeholder, it uploads it for conversion so it will be available in the future.
It seems optimistic to assume that Twitch will retain the current bitrate ceiling so we all get better quality, rather than saving money by reducing the bitrate to offer the same quality at less bandwidth. But hopefully that's how it will turn out, because oh boy does Twitch quality tank whenever there's a lot going on on screen.
The smart move would be splitting the difference. They get to slightly reduce their costs while slightly increasing stream quality, plus eliminate the royalty nonsense.
this is what netflix is allegedly doing too, with 2/3rds of their library in AV1 format now. The biggest complaint about streaming services is the quality reduction from the compression, and AV1 would allow services to offer more quality - but they probably wont when you can just cut costs and free up space.
The biggest price draw is actually re-encoding, which is solved by an entirely different feature in OBS that was just added called "Enhanced Broadcast" where the re-encoding is done locally on the steamers PC. The drawback of this feature is that you are basically streaming the same stream over 3-5 times to twitch, which is much harder on your upload speeds. What AV1 does is allow basically anyone to use said feature, despite having worse internet, as the net bandwidth can greatly be reduced while at the same level of quality as h264.
That's the whole point of using something open source. They don't need to lower the bitrate cap, they're already making a huge saving, and thus have improved margins. Twitch are dumb, but they aren't that dumb.
@@Youshisu and? New technology frequently requires new hardware support. New tech should never be held back until literally 100% of the world is fully complient with it.

@@dumant7975No. However, you will notice that if Twitch serves you an AV1 stream, your CPU usage might be higher than h.264 because your CPU doesn't have optimisations for AV1
In terms of media storage, I use AV1 10-Bit. For my Blu-ray movies that I back up, I can take a 36GB raw rip and bring it down, with next to no quality loss, combined with 640kbs OPUS audio for surround (128kbs per channel), 2-3gb, while for equiviant quality for other codecs would be 4-5gb in h.264 or 3-4gb in h.265. Downside is AV1 decode is computationally more demanding then h264/h265 if the machine that's doing the decoding doesn't have the dedicated hardware, like my 4k Chromecast w/ Android TV dongle (yeah, I have a dumb TV), meaning I have to set up transcoding back down to h264 on my TrueNAS scale server running Jellyfin. Lukily, I grabed a $50 Intel ARC gpu and its a low power video encoding BEAST. I seriously hope that the new 'set-top' streaming box that Google is releasing soon has dedicated AV1 decoding hardware.
At such high bitrates you're likely getting no benefit from AV1. It is comparable to h.264 and substantially worse than h.265 at bitrates above ~15 Mbps. H.265 is equal to or better than AV1 at all bitrates, however licensing it for commercial use is a nightmare.
@@rightwingsafetysquad9872Judging from their words, I'd say they're actually worried about file size post-encoding, since they're saving backups from discs. They're describing a 20-40% file size reduction for storage. Not everyone is prioritizing stream quality here.
@@impishlyit9780 Yes, but you can do that with any codec. They're not benefiting from using AV1 as opposed to h.264/5. You are always making a choice of either what gets me the best quality at my target bitrate, what gets me the lowest bitrate at my desired quality, or what is computationally the cheapest. The answer to the first 2 is always h.265. The answer to the third is always h.264. It is only when you're in a commercial setting that would necessitate paying royalties that AV1 becomes more desirable than h.265. You never get any benefit for using AV1 as opposed to h.265 for personal use. Furrhermore, I'm asserting that neither AV1 nor H.265 was necessary for this compression because above ~20 Mbps they all look basically the same anyway. His storage reduction did not depend on a new codec.
I don't think any of the devices involved actually have dedicated hardware for any codec, they have dedicated hardware for primitives (certain types of calculations). This means if AV1 doesn't have some exotic demands on the calculations front, even if the hardware was made before AV1 was ready, a sort of driver update could still work.
@@autohmaeYes they do. AMD cards have separate ASICS for H.26x family and for AV1. And different ones for encoding and decoding. IIRC, the AV1 in AMD cards came from XILINX IP. They were the ones already with hardware implementations of the codec. Bot ASICS and blocks for their FPGAs.
I knew that AV1 was a more efficient codec, but I didn't know that it was open source. That's awesome o: If I ever stream again then my 4090 will be outputting only the best quality for my 0 viewers c:
how efficient can it be if you need a 4000 series graphics card to encode and decode it. it kinda sounds like 8k. cool, but most people won't be able to use it for a long time.
@@crediblesalamander8056 It's more about having built in coprocessors in the GPU to make it really easy to encode. AV1 on the whole is also comparatively new (compared to h264/265) so the hardware support has just started showing up in the last couple years.
That's why I have a couple of Arc cards, A310 and A380, for use when I want to encode a great deal of stuff. My media server always has the A310 in it (single slot) for transcoding media to different nitrates and resolutions, while the A380 gets put into a workstation whenever I'm doing meaningful video work on that system. However, as of late, I've started just net catting the video stream over to the media server to process the video and just netcat the stream back.
@@OhhCrapGuy The a380 is such a cool piece of tech, got one myself for my stream encoding machine. Was a pain in the rear to get working in those first few months though.
I’m looking to build a new PC this upcoming winter, and the thing I’m having the most trouble wrapping my head around is PCIe bandwidth. Won’t getting a second card throttle the primary GPU? Or does that not matter for low end ARC cards?
@@RiverM8rix If my knowledge is correct, on most Motherboards your second (and sometimes third) PCIe slots don't interact with the first one at all. Usually, the first PCIe slot is the only one with the full x16 interface connected directly to the CPU, and the rest are either x8, x4, or x1 to save on lanes and are connected via chipset. If your board supports PCIe gen 4 or newer, most graphics cards should function fine on even x8 slots, but if you're only using it for encoding x4 (and even x1) should work fine. Encoding uses way less data than normal gameplay/rendering, so it's pretty easy to put it in a slot with less bandwidth. After doing some Googling, yea that isn't a problem. Using my mobo as an example (Asus x677 Prime-P AM5), I've got 28 PCIe 5.0 lanes supported by AM5. On my mobo (and all AM5 mobos if memory serves), 16 of those lanes are dedicated to the primary GPU slot. Another 8 are given to NVME drives. The last 4 are given to the chipset, which splits them across 2 more slots running PCIe 4.0 at x4 each, a PCIe 3.0 x1 slot, and an NVME slot running at PCIe 4.0 x4. For things running off the CPU directly (so my PCIe x16 slot and my first two NVME slots), bandwidth limiting will never be a problem since the CPU supports enough bandwidth for all of those slots. The chipset run slots theoretically could have bandwidth limiting, since it's splitting the lanes it has into more lanes. In practice, it's rather difficult to fully saturate those lanes since PCIe 5.0 supports 32 Gb/s transfer speed per lane, so I'd need to be using 128 Gb/s at the same time not counting my primary GPU and storage slots. An encoding card doesn't even get close to that under any normal workload, and even if it did it wouldn't touch my card on the x16 lane since that goes directly to the CPU and not through the chipset. Tl; dr: On any modern platform, if you plug your GPU into your primary slot it doesn't matter what the other slots do, they can't touch it.
1:02 You don't need a graphics card to encode AV1. SVT-AV1 at preset 11 is visually identical to what the current gpu generation can produce, and preset 10 already runs 4k60 on many cpus.
2:35 As far as decoding goes, tge software decoders are faster than realtime. That is the entire point behind AV1, complexity on the encoder side shouldn't be offloaded to the decoder side. Hardware decoders are just a tiny bit faster than software decoders, but save on power usage.
@@brettmurf if one is being a "serious" streamer, he probably would already get a cpu with many threads since things like layers, effects, etc, would still be done by the cpu, and some hardware encoders still requires some work by the CPU. Also, NVENC would produce garbage frames or skipping frames if the "gpu" part get overloaded, AMD's AMF and Intel QuickSync (and Arc) to my knowledge, never had this issue. So it can kinda get sometimes into a "pick your poison". I tried recording with SVT-AV1 encoder some Osu! gameplay and it was really fine, my Ryzen 5 1600 had 4 of its 6 cores banged up, but I imagine a faster, bigger processor could do it without losing frames @30fps while playing something more demanding like Cities Skylines 2 or smth
@@m3nguele okay, so a serious streamer would have a powerful CPU and GPU, but why make those components do unnecessary tasks when dedicated hardware for said task will do it faster than the CPU could possibly manage. It's just being inefficient for the sake of inefficiency
I got a cheap intel gpu about a year ago to encode youtube streams. The quality at the same bitrate was noticibly better, i dont get any interference with streaming on my gaming GPU. I used to have intel driver issues with fan speed making it super loud but it got patched at some point. 10/10 now.
I didn't even realize I could have been using AV1. That's pretty awesome to learn since I'm just starting to learn about video editing. Another awesome lesson from Thor

for decoding AV1, it shouldn't matter what graphics card you have, you don't need a 30xx card, you can decode in software, it just takes longer. you can buffer.
@@heavygaming6596 mobile devices have powerful CPUs capable of software decoding AV1, but it's still unusable because software decode is power inefficient
@@обычныйчел-я3е Google just updated most modern Androids though to use libdav1d instead of the older AV1 software decoder, so it shouldn't really take that much power anymore.
But twitch/youtube/whatever won't give you an AV1 stream unless you specifically request it, since your machine doesn't report having the capability to hardware decode. If you look in your chrome/firefox settings there's a toggle for AV1 as well, it's off by default if your machine doesn't have hardware decoding.
You can also have it on your iGPU inside your CPU if you don't want to change your graphics card. The AMD CPUs of the 8000G series has AV1 encoding (but not the 7000 or 9000)
I have several n100 mini PCs for this reason It has native av1 decode, so I can watch videos without decreased quality/increased power use from needing to do it in software Fantastic tech.
Vulkan encoding and decoding of h264, h265 and av1 is coming. That is multigpu and multiOS support for all codecs so linux also get windows level of codec support for those last % gamers that dont want to make the switch yet
I had no idea NVENC supported AV1, i thought it was only H.264 and H.265. This is useful for gameplay recording too, you can cut file sizes considerably on recordings while keeping identical quality. Great educational video!
ARC cards dont get enough credit for what they were for their time. They were moderately powerful cards, but their ability to AV1 encode was really good for the price.
Thor, just wanted to reach out to you because I was super excited today and thought you should know, as the "OP" so to speak.

It absolutely infuriates me there's no real stream settings in discord. Half the time it looks bad and there's no way for me to make it better. And the other half the time the stream lags to crap and gives me no feedback as to why.
It still uses av1 if you stream vom a system with a 4000 nvidia gpu (can't tell for other brands cards) to a system with a 4000/or 3000 nvidia gpu. If you enable developer mode you can look up the codecs that are uses for the stream.

For those of you who don't want to/can't shell out mega-moolah for an Nvidia card, AMD's Radeon 7000 and newer cards have this encoder as well, as do Intel's Arc cards. AV1 _decoding_ (aka the viewer's job) is supported by Nvidia 3000 and newer, Radeon 6000 and newer, and Arc cards. An important note: this is a _hardware_ encoder/decoder, as in a physical chip that's really good at doing this one task really fast. If you have an older card, it will simply run the encoding/decoding in _software,_ which works fine, but it'll be slower (leading to buffering).
Let’s be real Thor, Twitch will pocket the difference and still charge you for 4K.😂 Big fan of your content, mentorship and the funny stuff too, thank you for sharing.
@@nicolaspaglione spoken like a true fanboi, AMD has the BEST encoder for AV1, in fact it has major plaudits from anybody that uses AV1 for day to day work, it's just unfortunate that the NVENC encoder from Nvidia is pretty much mandatory for the time being due to software suite available from Nvidia.
AV1 is CRAZY. Re-encoded my H.264 videos to AV1 with the same settings, and it cut out 70% of the size (1GB->300ish MB) and it doesn't have any noticeable difference in quality. But Twitch doesn't support it yet so.......
I’m going through the process of converting everything on my media server to AV1 but it’s definitely been a process. I’ve got literally thousands of hours of video ranging anywhere from 480p x264 videos to 4kHDR x265. That alone would be a challenge but I don’t have new enough equipment to do hardware-accelerated AV1 encoding. So naturally I’m just having it done by the CPU (which most people would argue leads to better compression anyways) but it’s all being done by a measly 12C/24T Xeon from 8 years ago. The lower quality stuff that’s x264 encoded normally can be done in just a few minutes but I’ve got dozens of 4K movies that can easily take 7-8 hours to encode per movie. Thankfully most stuff made in the past 5 years has hardware accelerated AV1 decode but until decide to slap a new GPU in that server, that poor CPU is going to remain pegged at 100% usage for literally weeks
if its already encoded in h265 you're just wasting time and energy, h265 and av1 have similar performance for larger files (especially 4k), please dont waste ur time and go and buy anything new
About decoding: That is only for hardware decoding support, but decoding AV1 isn't that expensive compared to encoding. If your CPU is too old, you are out of luck, but pretty much all desktop CPUs and atleast more recent phone CPUs should work just fine. It most definitely will for 1080p for the vast majority, regardless of hardware support.
I’ve been using AV1 for years now just using my CPU, you are not only limited to GPU encoding. That said it is a very very heavy algorithm and takes up the whole CPU to do, so most cant do it without sacrificing half of your cores or having an entirely separate PC for encoding. Software decoding also is heavy, but I any device since 2017 should have enough power to play back AV1 via software with minimal hiccups
Software Decoding isn't heavy at all, as long as you have something decent enough to use Windows 10/11, it can decode av1 video. I did an informal experiment where I got a modern video player and an av1 encoded video onto my old Core 2 Duo desktop, and it was able to decode 720p30 with some hitches, and this is *without* fastdecode which is likely what most platforms would use.
As a fulltime Warframe streamer, I CANNOT WAIT for AV1, to the point that the moment it's announced I'll be upgrading my GPU instantly to a 7800 or 4080 super. it's going to make my life just so so much easier and better on a scale i can't even discribe. No more multi profiles for recording and streaming, no more worrying about if it looks like a potato (running a 3070 atm), Crispy clear video, being able to actually enjoy warframe at it's most beautiful. I just cannot wait anymore I really really want it asap.
Yep. I use Handbrake to encode some of my own ripped DVDs for putting it on my phone or backing it up. Handbrake supports the Nvidia AV1 hardware encoder. I've never used anything faster. 1 Mbit video(dvd resolution), Opus audio which is close to transparent at 128 kBit for stereo, and you're off to the races. Netflix has used this stuff for years already, as it was also one of the companies that supported the development. All free codecs for both video and audio.
What you're thinking of are the encoders x264 and x265, both H264 and H265 have patents which means services pay for their use, most H264 have expired so it's mostly free I think, but H265 is problem for services to use
rdna3 cards support it, but not for FHD, because they have an unfixable hardware bug that makes 1080p encodes impossible, you can only do the closest one, 1082p
And half of the reason why we don't use h.265 for most applications despite many video recorders being able to record it by default is because h.265 was a licensing nightmare compared to h.264. You'd have to convert a h.265 to a h.264 in order to use it in most editing programs like Premier Pro. AV1 fixes that issue in addition to being more efficient.
I used to swear by OGG (Vorbis), but if you're still using OGG, I recommend the newer, better open lossy audio codec, Opus! Opus is also amazing quality, beating every other standard codec at any given bitrate until transparency.
You can also encode using your CPU which is often higher quality than the GPU encoded variants. However requires a lot of CPU power, but if you already have a streaming PC this like won't be news to you. Higher presets using SVT-AV1 yield worse quality but faster encode times. It's a balancing act. But you can achieve H265 like performance and beat H265 in quality with the same encoding time in my testing.
Especially with a regular sized monitor, I have a 28" 4k monitor and I can't see the difference between 4k and 1440p even with my face smooshed up against the screen.
I will never forgive RUclips for killing off 360p60 and 480p60 video in the move to AV1. And even worse because AV1’s compression is most efficient at those resolutions
HEVC still has higher quality for local captures(100gb for 15 mins). Yes, AV1 will be the way to go for streaming as the compression\quality(size) ratio is maintained.
Comparing AV1 vs H264 make little sense, licencing price was never the problem with it, bandwidth is The real fight is between AV1 and HEVC (H265) which is as efficient as AV1 and doesn't require a last gen super expensive GPU to encode/decode, but it is also a paid licensed codec like H264
Dude AV1 is one of the best video advancements we’ve made in a long time and yet we still use H.264. It drives me wild that AV1 hardware is lagging so far behind.
Its hard for Twitch to support AV1 because the majority of streamers do not have the hardware to encode at AV1 smoothly, likewise there are many viewers who cannot decode AV1 smoothly on whatever hardware they are running. Thats why we are running enhanced broadcast over eRTMP so that people with advanced hardware can supply both AV1 and AVC renditions. Twitch cannot supply this on the backend because we don't have a cost effective solution of transcoding AV1, it is ridiculously hardware intensive compared to transcoding AVC (which we supply to streamers already). If you arent part of the enhanced broadcast beta, you can try it!
That's not an excuse, because: 1. Allowing people to stream in AV1 doesn't force everyone to do so. 2. if you're using hardware encoders, it would be trivial for the streamers to transcode to lower resolutions (or maybe even other codecs but I'm not sure) 3. Twitch could transcode av1 to h264 just like YT does (at least for VODs) 4. Outside of power consumption, software Decoding AV1 is quite fast on any decent cpu.
Definitely thinking of upgrading to a Arc A770 from a RX 6600 cause I'm pretty sure AMD Graphics Card's do not play nice with Overwatch. Lots of frames dropped and I want AV1 encoding.
If it was just for AV1 encoding there's a 15x cheaper option than a 4090 lol, the 4090 is cool because it's nice for AI (as much VRAM as the 3090) + it has AV1 encoding
I know Twitch was doing Enhanced Broadcasting Beta, I thought one of the things they were supposed to do with that is allow for AV1 streaming, but I guess thus far they've only allowed it to be used for multi-encoding h.264 on the streamers end for affiliates that may not get access to multi-encoding from twitch during peak usage hours. Although one downside to AV1 is it's very intensive to decode, so currently a lot of people still have computers with pre 11th gen Intel, pre-RDNA 2 AMD GPU or iGPs, or pre RTX-3000 Nvidia cards, or have a mobile phone with a chipset that doesn't do hardware AV1, so it's helpful to those people if at least some of the resolutions are still provided in h.264.
I am a member in the group for development of AV1.
The reason it has taken so long to adopt is because it was only in the last two years that the codec was stabilized to an acceptable enough degree for mass deployment.

The biggest complaint about streaming services is the quality reduction from the compression, and AV1 would allow services to offer more quality - but they probably wont when you can just cut costs and free up space.
The biggest price draw is actually re-encoding, which is solved by an entirely different feature in OBS that was just added called "Enhanced Broadcast" where the re-encoding is done locally on the steamers PC. The drawback of this feature is that you are basically streaming the same stream over 3-5 times to twitch, which is much harder on your upload speeds. What AV1 does is allow basically anyone to use said feature, despite having worse internet, as the net bandwidth can greatly be reduced while at the same level of quality as h264.
Twitch been having 4k support bitrate since spring in alpha/beta. A Higher bitrate should be available by end of year, maybe next spring.
google it.
That's the whole point of using something open source.
They don't need to lower the bitrate cap, they're already making a huge saving, and thus have improved margins.
Twitch are dumb, but they aren't that dumb.

@@dumant7975No. However, you will notice that if Twitch serves you an AV1 stream, your CPU usage might be higher than h.264 because your CPU doesn't have optimisations for AV1
@@dumant7975if youtube is fine now it will be fine.
In terms of media storage, I use AV1 10-Bit. For my Blu-ray movies that I back up, I can take a 36GB raw rip and bring it down, with next to no quality loss, combined with 640kbs OPUS audio for surround (128kbs per channel), 2-3gb, while for equiviant quality for other codecs would be 4-5gb in h.264 or 3-4gb in h.265.
Downside is AV1 decode is computationally more demanding then h264/h265 if the machine that's doing the decoding doesn't have the dedicated hardware, like my 4k Chromecast w/ Android TV dongle (yeah, I have a dumb TV), meaning I have to set up transcoding back down to h264 on my TrueNAS scale server running Jellyfin. Lukily, I grabed a $50 Intel ARC gpu and its a low power video encoding BEAST.
I seriously hope that the new 'set-top' streaming box that Google is releasing soon has dedicated AV1 decoding hardware.
At such high bitrates you're likely getting no benefit from AV1. It is comparable to h.264 and substantially worse than h.265 at bitrates above ~15 Mbps. H.265 is equal to or better than AV1 at all bitrates, however licensing it for commercial use is a nightmare.
@@rightwingsafetysquad9872Judging from their words, I'd say they're actually worried about file size post-encoding, since they're saving backups from discs. They're describing a 20-40% file size reduction for storage. Not everyone is prioritizing stream quality here.
@@impishlyit9780 Yes, but you can do that with any codec. They're not benefiting from using AV1 as opposed to h.264/5.
You are always making a choice of either what gets me the best quality at my target bitrate, what gets me the lowest bitrate at my desired quality, or what is computationally the cheapest. The answer to the first 2 is always h.265. The answer to the third is always h.264. It is only when you're in a commercial setting that would necessitate paying royalties that AV1 becomes more desirable than h.265. You never get any benefit for using AV1 as opposed to h.265 for personal use.
Furrhermore, I'm asserting that neither AV1 nor H.265 was necessary for this compression because above ~20 Mbps they all look basically the same anyway. His storage reduction did not depend on a new codec.
I don't think any of the devices involved actually have dedicated hardware for any codec, they have dedicated hardware for primitives (certain types of calculations).
This means if AV1 doesn't have some exotic demands on the calculations front, even if the hardware was made before AV1 was ready, a sort of driver update could still work.
@@autohmaeYes they do. AMD cards have separate ASICS for H.26x family and for AV1. And different ones for encoding and decoding. IIRC, the AV1 in AMD cards came from XILINX IP. They were the ones already with hardware implementations of the codec. Bot ASICS and blocks for their FPGAs.

@@crediblesalamander8056 It's more about having built in coprocessors in the GPU to make it really easy to encode. AV1 on the whole is also comparatively new (compared to h264/265) so the hardware support has just started showing up in the last couple years.
Apparently using one of lowend Intel Arc cards a secondary GPU in your system is a price efficient way to get access to AV1
That's why I have a couple of Arc cards, A310 and A380, for use when I want to encode a great deal of stuff.
My media server always has the A310 in it (single slot) for transcoding media to different nitrates and resolutions, while the A380 gets put into a workstation whenever I'm doing meaningful video work on that system.
However, as of late, I've started just net catting the video stream over to the media server to process the video and just netcat the stream back.

@@OhhCrapGuy The a380 is such a cool piece of tech, got one myself for my stream encoding machine. Was a pain in the rear to get working in those first few months though.
I’m looking to build a new PC this upcoming winter, and the thing I’m having the most trouble wrapping my head around is PCIe bandwidth. Won’t getting a second card throttle the primary GPU? Or does that not matter for low end ARC cards?
@@RiverM8rix If my knowledge is correct, on most Motherboards your second (and sometimes third) PCIe slots don't interact with the first one at all. Usually, the first PCIe slot is the only one with the full x16 interface connected directly to the CPU, and the rest are either x8, x4, or x1 to save on lanes and are connected via chipset. If your board supports PCIe gen 4 or newer, most graphics cards should function fine on even x8 slots, but if you're only using it for encoding x4 (and even x1) should work fine. Encoding uses way less data than normal gameplay/rendering, so it's pretty easy to put it in a slot with less bandwidth.
After doing some Googling, yea that isn't a problem. Using my mobo as an example (Asus x677 Prime-P AM5), I've got 28 PCIe 5.0 lanes supported by AM5. On my mobo (and all AM5 mobos if memory serves), 16 of those lanes are dedicated to the primary GPU slot. Another 8 are given to NVME drives. The last 4 are given to the chipset, which splits them across 2 more slots running PCIe 4.0 at x4 each, a PCIe 3.0 x1 slot, and an NVME slot running at PCIe 4.0 x4. For things running off the CPU directly (so my PCIe x16 slot and my first two NVME slots), bandwidth limiting will never be a problem since the CPU supports enough bandwidth for all of those slots. The chipset run slots theoretically could have bandwidth limiting, since it's splitting the lanes it has into more lanes. In practice, it's rather difficult to fully saturate those lanes since PCIe 5.0 supports 32 Gb/s transfer speed per lane, so I'd need to be using 128 Gb/s at the same time not counting my primary GPU and storage slots. An encoding card doesn't even get close to that under any normal workload, and even if it did it wouldn't touch my card on the x16 lane since that goes directly to the CPU and not through the chipset.
Tl; dr: On any modern platform, if you plug your GPU into your primary slot it doesn't matter what the other slots do, they can't touch it.
1:02 You don't need a graphics card to encode AV1. SVT-AV1 at preset 11 is visually identical to what the current gpu generation can produce, and preset 10 already runs 4k60 on many cpus.
2:35 As far as decoding goes, tge software decoders are faster than realtime. That is the entire point behind AV1, complexity on the encoder side shouldn't be offloaded to the decoder side. Hardware decoders are just a tiny bit faster than software decoders, but save on power usage.
Okay, but do you want your CPU doing that while it is also running a game?
@@brettmurf if one is being a "serious" streamer, he probably would already get a cpu with many threads since things like layers, effects, etc, would still be done by the cpu, and some hardware encoders still requires some work by the CPU.
Also, NVENC would produce garbage frames or skipping frames if the "gpu" part get overloaded, AMD's AMF and Intel QuickSync (and Arc) to my knowledge, never had this issue.
So it can kinda get sometimes into a "pick your poison".
I tried recording with SVT-AV1 encoder some Osu! gameplay and it was really fine, my Ryzen 5 1600 had 4 of its 6 cores banged up, but I imagine a faster, bigger processor could do it without losing frames @30fps while playing something more demanding like Cities Skylines 2 or smth

Those days that I lost can't be recovered .
@@m3nguele okay, so a serious streamer would have a powerful CPU and GPU, but why make those components do unnecessary tasks when dedicated hardware for said task will do it faster than the CPU could possibly manage. It's just being inefficient for the sake of inefficiency
I got a cheap intel gpu about a year ago to encode youtube streams. The quality at the same bitrate was noticibly better, i dont get any interference with streaming on my gaming GPU. I used to have intel driver issues with fan speed making it super loud but it got patched at some point. 10/10 now.

For those of you who don't want to/can't shell out mega-moolah for an Nvidia card, AMD's Radeon 7000 and newer cards have this encoder as well, as do Intel's Arc cards. AV1 _decoding_ (aka the viewer's job) is supported by Nvidia 3000 and newer, Radeon 6000 and newer, and Arc cards.
An important note: this is a _hardware_ encoder/decoder, as in a physical chip that's really good at doing this one task really fast. If you have an older card, it will simply run the encoding/decoding in _software,_ which works fine, but it'll be slower (leading to buffering).

I’m going through the process of converting everything on my media server to AV1 but it’s definitely been a process. I’ve got literally thousands of hours of video ranging anywhere from 480p x264 videos to 4kHDR x265.
That alone would be a challenge but I don’t have new enough equipment to do hardware-accelerated AV1 encoding.
So naturally I’m just having it done by the CPU (which most people would argue leads to better compression anyways) but it’s all being done by a measly 12C/24T Xeon from 8 years ago.
The lower quality stuff that’s x264 encoded normally can be done in just a few minutes but I’ve got dozens of 4K movies that can easily take 7-8 hours to encode per movie.
Thankfully most stuff made in the past 5 years has hardware accelerated AV1 decode but until decide to slap a new GPU in that server, that poor CPU is going to remain pegged at 100% usage for literally weeks
If you have access to A310 just get it

I’ve been using AV1 for years now just using my CPU, you are not only limited to GPU encoding. That said it is a very very heavy algorithm and takes up the whole CPU to do, so most cant do it without sacrificing half of your cores or having an entirely separate PC for encoding. Software decoding also is heavy, but I any device since 2017 should have enough power to play back AV1 via software with minimal hiccups
Software Decoding isn't heavy at all, as long as you have something decent enough to use Windows 10/11, it can decode av1 video.
I did an informal experiment where I got a modern video player and an av1 encoded video onto my old Core 2 Duo desktop, and it was able to decode 720p30 with some hitches, and this is *without* fastdecode which is likely what most platforms would use.

Wait a minute, isn't H,264 open source but less efficient, and H.265 encoding being what cost money...
What you're thinking of are the encoders x264 and x265, both H264 and H265 have patents which means services pay for their use, most H264 have expired so it's mostly free I think, but H265 is problem for services to use

@@rzr82Intel was first, followed by Nvidia and finally AMD.
And half of the reason why we don't use h.265 for most applications despite many video recorders being able to record it by default is because h.265 was a licensing nightmare compared to h.264. You'd have to convert a h.265 to a h.264 in order to use it in most editing programs like Premier Pro. AV1 fixes that issue in addition to being more efficient.

You can also encode using your CPU which is often higher quality than the GPU encoded variants. However requires a lot of CPU power, but if you already have a streaming PC this like won't be news to you. Higher presets using SVT-AV1 yield worse quality but faster encode times. It's a balancing act. But you can achieve H265 like performance and beat H265 in quality with the same encoding time in my testing.

They keep using the Chad thor face and I love it everytime
I will never forgive RUclips for killing off 360p60 and 480p60 video in the move to AV1. And even worse because AV1’s compression is most efficient at those resolutions
HEVC still has higher quality for local captures(100gb for 15 mins). Yes, AV1 will be the way to go for streaming as the compression\quality(size) ratio is maintained.
Comparing AV1 vs H264 make little sense, licencing price was never the problem with it, bandwidth is
The real fight is between AV1 and HEVC (H265) which is as efficient as AV1 and doesn't require a last gen super expensive GPU to encode/decode, but it is also a paid licensed codec like H264
As a fan of Warframe, thank you for mentioning it.
AV1 can be decoded in software by practically any modern desktop CPU so its pretty nice as long as companies implement it
intel Arc is the best for AV1 encoding and is much cheaper than a 4090. You can use it conjunction with your discreet GPU for gaming.

I think it's because AV1 is something new, they want to do it right and thus are taking their time to get it right.
Its hard for Twitch to support AV1 because the majority of streamers do not have the hardware to encode at AV1 smoothly, likewise there are many viewers who cannot decode AV1 smoothly on whatever hardware they are running. Thats why we are running enhanced broadcast over eRTMP so that people with advanced hardware can supply both AV1 and AVC renditions. Twitch cannot supply this on the backend because we don't have a cost effective solution of transcoding AV1, it is ridiculously hardware intensive compared to transcoding AVC (which we supply to streamers already). If you arent part of the enhanced broadcast beta, you can try it!
That's not an excuse, because:
1. Allowing people to stream in AV1 doesn't force everyone to do so.
2. if you're using hardware encoders, it would be trivial for the streamers to transcode to lower resolutions (or maybe even other codecs but I'm not sure)
3. Twitch could transcode av1 to h264 just like YT does (at least for VODs)
4. Outside of power consumption, software Decoding AV1 is quite fast on any decent cpu.
4k 60fps becoming the standard is actually insane
Circletoons is what gaming journalism should be.
For a moment I thought we went back to the early 2000 with the .avi video files
Definitely thinking of upgrading to a Arc A770 from a RX 6600 cause I'm pretty sure AMD Graphics Card's do not play nice with Overwatch. Lots of frames dropped and I want AV1 encoding.
Not sure how nicely Arc will play with dx11 so make sure you do your research first
The other saving is that they can push the same res at a lower data cost
That last question was probably meant to address bandwidth, not royalties, because that was already said before.
If it was just for AV1 encoding there's a 15x cheaper option than a 4090 lol, the 4090 is cool because it's nice for AI (as much VRAM as the 3090) + it has AV1 encoding
AMD 7000 GPUs also encode it. My 7900xt does it.
I know Twitch was doing Enhanced Broadcasting Beta, I thought one of the things they were supposed to do with that is allow for AV1 streaming, but I guess thus far they've only allowed it to be used for multi-encoding h.264 on the streamers end for affiliates that may not get access to multi-encoding from twitch during peak usage hours. Although one downside to AV1 is it's very intensive to decode, so currently a lot of people still have computers with pre 11th gen Intel, pre-RDNA 2 AMD GPU or iGPs, or pre RTX-3000 Nvidia cards, or have a mobile phone with a chipset that doesn't do hardware AV1, so it's helpful to those people if at least some of the resolutions are still provided in h.264.
7900 gaming rig to Pixel via AV1+Remote Desktop is a dangerous combo for keeping you in bed
