Twitch Enhanced Broadcasting (Multi-Encode Streaming) Powered by NVIDIA GeForce RTX GPUs

Today many streamers must choose between higher resolution and reliable streaming. High-quality video provides more enjoyable viewing experiences but causes streams to buffer for viewers with low bandwidth or older viewing devices. Streaming lower-bitrate video allows more people to watch the content seamlessly, but introduces artifacts.

Twitch, OBS and NVIDIA have collaborated on a new feature to address this — Twitch Enhanced Broadcasting, releasing in beta later this month. Using the high-quality dedicated encoder (NVENC) in modern GeForce RTX and GTX GPUs, streamers will be able to broadcast up to three resolutions simultaneously at up to 1080p.

NVIDIA GPUs accelerate your work with incredible boosts in performance. Less time staring at pinwheels of death means bigger workloads, more features, and creating your work faster than ever. Welcome to NVIDIA Studio—and your new, more creative, process. RTX Studio laptops and desktops are purpose-built for creators, providing the best performance for video editing, 3D animation, graphic design, and photography.

In other words, Twitch is offloading their server-side transcoding to the broadcaster to save money on server costs. Stay tuned for the reviews to see if the extra workload is worthwhile.

Considering so many people have GPU's with completely underutilized encoding chips on them, and Twitch don't give a lot of their streamers transcoding, this could be a really good compromise. It just might cost someone their upload connection. What you have to love about AV1 is that your crappy internet connection (there are still plenty of connections around the world that are VERY asymmetrical) can finally make your stream look acceptable, so I hope transcoding on the streamers end at multiple resolutions/FPS is optional.

So instead of sending one high quality 1080p60 stream at 8000 bitrate and having Twitch transcode we get to send multiple lower quality streams at lower bitrates because we still have to stay below 8000 bitrate... But AV1! Yeah, the 40% quality increase that AV1 provides goes out the window once streamers are forced to encode multiple streams and fit them within 8000 bitrate. Twitch and Nvidia are trying to make this sound like a positive thing but the only reason they are adding AV1 is so that they can offload transcoding to streamers and save money.

AV1 isn't new though it came out with 29.0 OBS? Just be nice for Twitch to give us atleast 10-15k bitrate.

[ArthurTully]

Why would I take on transcoding? This is done on twitches side but AV1 is nice I guess.
Also why does it show 4k since twitch does not support 4k at all?

[UnfairMode]

Wow. I never thought high-quality streaming could be a problem for viewers. I thought Twitch could manage the quality according to the user's connection.

[sergeygorbov]

I dont really get why i should use this transcodind (also sacrificing up to 15% of my gpu perf) instead of twitch server-side transcoding?

[promithos]

Finally AV1 being adopted by Twitch! but...not sure if this means we have to stream from one PC? Will dual PC stream setup be possible?

[windseries]

So the beta twitch studio actually could use AV1 or not ?

[AgentSmith]

I don't wanna watch 4K at 60 FPS, but rather 1440 at 120 FPS

[proguni]

Will this allow ultrawide res streaming to Twitch? (3440X1440 enjoyer here)

[Flafik_]

nvidia once every 100 years. releases a video that talks about cool improvements on streams, but a lot of time passes before it all starts working. Stupid advertising. Twitch promised us a beta test of AV1 a very long time ago, where is at least one video on YouTube that AV1 is already working in OBS on Twitch? no. and most importantly, you didn’t show how much better your Avi1 is than the Av1 through a good processor or through the cheapest Avi1 Intel card! since a normal streamer will stream through 2 PCs. and your method is only suitable for saving in the case of 1 pc.

[TheMinigato]

Don't forget Twitch already did this for you, but they no longer want to do it because it costs them money! It's not a feature....

[thecooldudes]

This is why I've upgraded from an AMD GPU to an NVIDIA GPU.

[AzumDzumHzumS]

does multi stream work with amd 7000 cards? ;)

[derios]

And how does this actually work?
Will a twitch streamer need a 100M/bit upload rate todo this? If the GPU can handle multiple resolutions for the live stream thats fine for me.
BUT the twitch streamer needs to upload ALL resolution stream to the witch servers?
Doesnt this more or less DOUBLE the bandwith usage you need to make this streams?

[SevendashGaming]

Honestly, very excited for this. Hoping to get into the Twitch Beta to put this 4080 to good use!

[RambossTV]

wait what? Do they really want to sell this to us as a new function that allows viewers with bad internet to lower the resolution? xD

[MajinErick]

The problem is the GOP in the software. For our modern systems, the GOP is too low.

[Czari]

imagine have any rtx and some high-end processor and have lags 💀💀
