In this tutorial we’ll show you how to stream on twitch with OBS Studio streaming software.
First of all, you need to download OBS and install it. Then, follow the instructions below.
In the first step you should get a twitch stream key for OBS. You can find it in your Twitch dashboard (tab Stream Key).
1. In OBS Studio go to “File” → “Settings” → “Stream” and set “Stream Type” to “Streaming Services”
2. Choose “Service” → “Twitch”
3. Choose “Server” which is closest to your location
4. Enter “Stream key” which you’ve got in your dashboard on Twitch.TV
In the second step you should configure OBS Studio for the best quality and performance. Twitch developers are recommending these settings:
1. Rate Control: CBR
2. Aspect ratio: 16:9 (that means you need to use resolutions such as 1920×1080, 1280×720, etc.)
3. Video bitrate (kb/s):
* 1080p: 6000
* 720p: 4500
* 1080p: 4500
* 720p: 3000
* 480p: 1500
4. Keyframe interval: 2
5. Audio: AAC with a bitrate 64-128 kb/s
Also it is worth mentioning advanced settings. You can use different encoders (x264, Intel QSV, Nvidia NVENC H.264, AMD AMF) and presets for them. For more information on this and for further instructions about scene setup you can read an article: how to setup OBS Studio for streaming.
