Twitch LOW LATENCY Streaming: How to stream with 1 second of latency

[@kossler]

Adam, I love the black background set! It looks super slick! You definitely use it more often!

[@Ponden]

Would love to see a video going through the Stream FX plug-in settings and what's best to use etc.

[@NitroBlaziken]

Would love to see you do a full in depth guide on StreamFX encoder settings for both Recording and Streaming due to there not being many (at least video) tutorial information out there currently would be a huge help to those of us who are mainly visual and auditory learners.

[@Xaymar]

That would be a two hour long video going into extreme detail about H.264, human perception, color compression techniques, and a lot of other things. I'd love to see that as well 😂

[@NitroBlaziken]

Literally just watched this video and implemented the method before starting a stream, my latency now constantly floats between 0.99-1.01 seconds.. #thumbsup

[@lucianoventurieri7628]

How do you achieve that? Even with all the settings in the video my latency is like 4 seconds

[@thetaburnmusic]

Yo, skip to 5:09 for the tutorial. . The first 5minutes is extraneous nerdsplaining and an in video ad.

[@aquamarinerose5405]

At risk of sounding overly dramatic, changing my keyframes made things even worse because it felt like it added frame lag while keeping the delay I had.

[@JG41]

Bro this is badass, thank you!

[@Bombanade]

GREETINGS! Appreciate the video! do you have an updated setting for Streaming with Xaymar's latest version? settings some different settings from this video to the updated one. Cheers!

[@Ellipsis115]

5:07 This is all you need to know. Other than for whatever reason, although a keyframe interval of 1 second should be better than 1.5 which should be better than 2, apparently this guy found only 1.5 worked (possibly only for him?!?). Warning this is 2 minutes of really dense info, might even download and just have a clip of the hundred seconds after 5:07 on my pc.

[@vladvoloshenko5701]

your room is nice, good job) and thanks for the video!

[@Phoenykz]

It works!! Was able to get latency down to 1.05-1.10 seconds with 8k bitrate. Will need to do more tests and see how that affects overall stream and if there is any noticeable issues that comes up in VODs. But this is indeed incredible.

[@seanwatts392]

Do you stream on youtube? I stream on twitch and twitch only let's users stream at 6k bitrate unless your a partner. 😭😭

[@Phoenykz]

@@seanwatts392you don’t need to be partner to stream at 8k bitrate. Within OBS you need to untick “enforce streaming encoder settings”. During the first few minutes of your stream, check to make sure it is at the resolution you are streaming at, and if you have transcoding options. If not, restart your stream. 90% of the time I get transcoding options. Note that YMMV due to specific time of day you stream at.

[@seanwatts392]

@@Phoenykz yes but they will down scale you and they could also shut down your account. It's in there terms. Look into it. It's one of those word of motuths that it's OK to use 8k but many people don't know they will push it back down sometimes way below 6k

[@TTimmy41]

Do you have a tutorial on how you color grade and edit the look fo your footage? It's so pretty.

[@WarMomPT]

Not quite 1 second, but I did see some improvement! With OBS' normal NVENC implementation and StreamFX at a keyframe interval of 2, I had around 4 seconds of latency to twitch (according to the stats tab). With keyframe interval of 1.5 on StreamFX, the stats tab said I had 1.09 seconds of latency, though the actual amount (measuring a timer hitting 0 in my game vs hitting 0 on stream) was just under 3 seconds, but it sure as hell felt a good bit better than before which would be around 4s on the same test - it should also be considered that I'm lucky enough to be on pretty good fiber internet

[@ramon4stunts_]

I followed everything you did but still stuck at 7 secs of a delay on twitch

[@AnthonyGoodley]

Do you have a video where you review the EVGA XR1 that youre last 2 videos mention? How does it compare to the Elgato HD 60 S & S+?

[@ThekappaConvict]

@EposVox any chance there would be a free plugin to do this kind of thing as the person who did this before put it all behind an expensive pay wall???

[@Naigg]

my obs studio menu system looks a lot different from yours. So was hard finding some of the menus you were going into, but found them after some poking around.

[@VPC]

Looks like a 1.5 keyframe interval is possible with the AMD encoder in the advanced settings as well

[@Xaymar]

Yes, but it only works on some cards. For some reason, newer models sometimes ignore it entirely and default back to 1.0s

[@Bombanade]

PSA: UPDATING TO THE NEWEST OBS FOR FEB 14TH 2022 WILL NOT ALLOW YOU TO BROADCAST USING THE STREAMFX PLUGIN FOR SOME REASON. YOU WILL GET THE FOLLOWING ERROR: "Starting the output failed. Please check the log for details. Note: If you are using the NVENC or AMD encorders, make sure your video drivers are up to date."

[@Quintaslive]

My obs shows 32000 kb/s and my twitch says unstable. I copied the exact same settings as eposvox. Does anyone know what it can be? Using a 1050ti encoder and my internet is 100 mega bit per second

[@meco]

Usually Download speed isnt the same as upload also twitch doesn’t want that high Bitrate

[@Quintaslive]

@@meco I have 500 down and 100 up, I inserted 6000 bit rate, do I need to change anything cuz of my download?

[@Hzuuuu]

@@Quintaslive Try this: Type "-maxrate=6M" in the "Custom Settings" text field in the "FFmpeg Options" section. That should fix the bitrate going way over the limit. StreamFX doesn't have the max bitrate text field shown in CBR mode unlike the VBR modes.

[@MichaelTheBruce]

Not that you haven’t done enough reviews/roundups of capture cards. Any thoughts on the new Genki ShadowCast? I finally got my order. As with most kickstarters, I only ordered on the chance it’s an impressive alternate to others in my setup. Very interesting that a capture card is marketed for “gaming on the go” if the only monitor you have is a laptop.

[@beboobailey]

While this worked initially (getting 1.02s latency), after watching my test stream for a few minutes, the stream freezes occasionally, starts skipping hundreds of frames and latency shoots up to 12 sec and stays there while still skipping frames. No drops in OBS. Any idea why this would happen?

[@Xaymar]

Poor Internet conditions. The player will automatically self correct if your Internet can't handle the latency and forcefully delay the stream in order to provide smooth playback even in the worst conditions.

[@gossamerstyle]

Did you view vod right after publishing/streaming? Give it a couple hours to fully upload. I see this on many streamers vods

[@spinnerx828]

what if my encoder is at nividia nvenc h .264 (new) what do i change it to

Hey does this still work? streamFX has alot of changes now, could you remake this video if you got any new findings?

Is the 1.5 keyframe interval still "a thing" in 2023 with the new OBS encoders released? Does this "trick" still do it's magic or shouldn't it be used anymore?

Hi how do i install the plug-in for NVENC ?

Since keyframes take up more "space" in the encode, and this creates 33% more of them, how much overhead does this cause in terms of bitrate?

4% on Turing/Ampere.

Xaymar's OBS resource area for the FFmpeg Encoder says I'll have to go in and remove the default encoders for them to work. Do you happen to have a video explaining this or does anyone have any idea the steps I need to take here before I do something that'll just brick my OBS. I need help!

how can i add this plug in?

[@senzayyzone]

I have a question about this, so for this when it comes to hardware what is more important the graphics card or the network card to the get best stream quality?

[@EposVox]

Graphics card. Every pc made in the last 15 to 20 years has way more than good enough of a network interface lol

[@technicolourmyles]

Is it correct to assume this would also slightly improve performance when editing (if you also record the VOD with 1.50s keyframe interval)?

[@Xaymar]

It will allow faster seeking, yes.

[@trentbauer7897]

It looks like the dev's have added a 'zero latency' option under 'Other Options' Do we want to enable this?

[@Xaymar]

As addressed in the video and the original blog post, it has no effect on latency. Zero-Latency is primarily aimed at reducing decoding latency, but GPUs these days can decode H264 at 1000 fps or more, so it became a pointless option for anything but Blu-Ray discs.

[@TheHomelessMan404]

Man I do miss mixer

[@napoellisyt]

Can you help me set up the recording settings? I was able to record but then I can't watch the videos/put them into editing software even though it's an .mp4 file

[@SirP3rcival]

Great video! Quick question. Is the buffer size you have universal? If not, how do we adjust it according to our setups? Thanks man :)

[@AngryApple]

Didnt change a thing, but I usually already have a delay of 2 seconds and a streamer I always watch is already on 1 second without any of these settings. Maybe its a europe thing because the servers are much closer here?

[@EposVox]

Xaymar is in Europe lol

[@AngryApple]

@@EposVox hmm setting the Interval to 1 second results in 1.8 seconds instead of 2-2.4 seconds. Will investigate further 🤔

[@pcislocked]

what if we drop the keyframe under 1 seconds?

[@Xaymar]

In my testing, values below 1s had no effect. They would simply snap to the same latency as 1s, although with drastic impact on quality.

[@pcislocked]

@@Xaymarthanks for replying. I also conducted some testing just recently and didn't see any changes below 1.5s. I think most latency is generally on the twitch's CDN side and/or client's playback buffer due to network conditions.

[@n1kobg]

Is this will cause my system more resources, input lag or similar issues when i want to proritize the game not the stream? I would like a video how to setup a stream in a competitive environment when you dont care too much of the quality (stream in 480-720p) that causes as little latency as possible to the game when you play in a cup for example. Is there something else to be done except the usual quality settings and run as administrator. Thanks Ps: many times streaming or recording is a requirement.

[@Syinite]

I'm getting 0.5 seconds consistent!

[@OEGG]

sheesh

[@dunste123]

Gonna try this :)

[@Hzuuuu]

EposVox, have you tried the NVENC CQ mode in StreamFX? Is it worse than VBR or is it a contender for CBR-like quality while also having variable bitrate at the same time?

[@binaryatlas]

will views have to toggle the low latency setting too for it to work?

[@EposVox]

Generally no. It’s enabled by default for viewers when you turn it on as a streamer

[@binaryatlas]

@@EposVox well mine was on too but I had to toggle it to get it to go to 1 second. was not sure if a viewer would have to do the same thing

[@Sintexify]

Please can you cover latency on KZbin at the different resolutions :)

[@deivedux9342]

All I know is that KZbin *always* provides quality options for streams, due to them already applying compression on uploaded videos since the beginning. The higher resolution and/or FPS you stream at, the more difficult it is for KZbin to keep up with the compression, not only because of high resolution, but because of the number of transcodes it has to do at the same time. See my latest video, for instance (puu.sh/HC1oK/5efa91591a.png) or, even better, this very video (puu.sh/HC1wX/fac9a24a08.png). Because of that, the higher your resolution of choice, the less chance you have for KZbin even allowing you to stream at low latencies, because it knows that it will not be able to keep up with so many transcodes fast enough.

[@itzhu1k208]

I dont see it on my settings

[@undeadhero9141]

thank you i was having 10 sec delay now with 1 key interval i have 7 seconds at 1440p on youtube

[@Deveron4]

Man, FTL was so cool. Whoah, interval 1.5... crazy

[@Scotts_Arcade]

So something I noticed with your settings, in comparison to my own. First is the encoder, it shows as H.264/AVC Nvidia NVENC, yet in OBS Studio it shows as Nvidia NVENC H.264/AVC (via FFMPEG) for my setup . The second, and I'm guessing this is tied to the first difference, is the B-Frame Reference Mode, it shows as 'Use only middle B-Frames as reference'. So I think it's because of the FFMPEG. Other then that, the setup looks spot on. My question is this, will this difference really affect things overall, or is it in my best interest to remove the FFMPEG driver from OBS Studio. Great video as always and thanks for the concise information.

[@EposVox]

Yours might look slightly different because I’m on an older version of StreamFX. There’s no such thing as a “FFMPEG Driver” and you can’t remove FFMPEG from OBS. Just slightly different UI labeling for the different versions of the StreamFX Plugin

[@Scotts_Arcade]

@@EposVox I just realized that after doing some fiddling around with things. Was just curious is all. That being said, really looking forward to trying this out myself. As for the FFMPEG 'driver', it was just now I realized how wrong that is. Thanks again for the great adive.

[@Chrono-MR]

I got 1.04 pretty consistently!

[@BorrietheBlade]

If you use x264, do you still need to install the plug in? I took it as if you use Nvenc you would need to install the plug but NOT if you are on x264. I missed your class on using the "tune" setting to "zerolatency" but I had it set to that from my own testing when I built my 2nd pc for stream purposes. The quality of the feed was better on that "tune" for some reason. I know, I know. Shame on me. Thanks for the video, as always EposVox

[@EposVox]

Only need the plugin if doing NVENC

[@XcutAngel]

that nvenc encoder you used makes my output fail. What works is the build in one "NVIDIA NVENC H.264 (new)" What fails is the one you chose: "NVIDIA NVENC H.264/AVC (via ffmpeg)" I'm not sure what I should do to fix this, but when I click stream , I get the error: "starting the output failed. note: if you're using NVENC or AMD encoders, make sure your video drivers are up to date"

No. KZbin forcefully transcodes to VP9, which requires quite a high buffer on their end to look decent, so KZbin will always be a significant amount of time behind.

[@jazrael]

Thank you!

[@MateuszZych]

U use bframes=4?

[@Xaymar]

The settings provided here are a slightly earlier version from my recommended streaming settings: blog.xaymar.com/2020/06/24/the-art-of-encoding-with-nvidia-turing-nvenc/ . With Adaptive B-Frames on, NVENC intelligently picks out the best number of B-Frames to use.

[@shanksisnoteventhatstrongbruh]

I wonder if this would be good for the garbage 5700xt encoder, too bad my connection is actual poop(currently 100kbps download and 10kpbs upload :/) and i can't test it. I used to have 200/20 mbps too...

[@ryanlaseter7626]

So looking at my test stream account, when viewing the video from another PC, I see 1.05s of a broadcast latency with my normal CPU encoding settings on a 5900X. However, I see around 4 seconds of effective delay which is not too bad. I tried your suggested 1 and keyint=90 (I stream 60fps). I didn't notice much of a difference, still around a 4 second effective delay. Perhaps I can still leave this keyframe setting here and test it out in my stream? At least it'd make the only potential bottleneck my router and upstream connection to Twitch and not my own settings xD I did not test out/change my ingest server location and I was running some decent networking stuff at the time, perhaps the one that I'm using just happens to have a slower connection for me. I'll try that too!

[@Xaymar]

CPU encoding has an inherent latency based on resolution, framerate and preset chosen.. You won't affect it much on the transport side.
