OBS – Basic Recommend Settings for New Streamers

These are some simple basic, and recommended, settings which I generated while working at Mixer for new streamers. These settings are for lower end 720p 30FPS streams, however, you can use them as a baseline and update them as needed. These settings are designed for users with low upload speed, however you should note that if your upload is less than 1.8Mbps (1800kbps bitrate) then you will (most likely) not be able to upload a watchable quality stream.

The first thing you’ll do is access the settings option in OBS.

Open Broadcast Software (OBS)

Once in the Settings window, you will want to pay attention to the left navigation pane. General, Stream, Output, Audio, Video, Hotkeys, Advanced. For this example, we’ll be paying attention to only video settings which means we will be using the Stream, Output and Video sections.

Service: Mixer FTL
Server: Choose the server that is closest to you.
Stream Key: Your stream key, from mixer.com.

Stream settings in OBS

Output -> Advanced
Encoder: x264
Rate Control: CBR
Bitrate: 1800
Keyframe Interval: 1
CPU Usage Preset: very fast
Profile: None
Tune: None
x264 Options: b-frames=0

Base (Canvas) Resolution: 1920×1080 (or make this the same as your desktop resolution, for example, if your desktop resolution is in 720p then set this to 1280×720).
Output (Scaled) Resolution: 1280×720
Downscale Filter: Lanczos (32 samples)
Common FPS values: 30

Video settings in OBS

Now that you’ve copied these settings into OBS, you can start streaming. Check the quality of your stream by watching your channel while it’s live. Keep in mind, that you should never watch your own stream for very long while streaming, especially if you’re watching on the same computer you are streaming or playing from. If you watch your stream while you are live it will cause higher CPU usage.

Some other options you will want to note is that b-frames=0 is crucial for Mixer FTL as it does not accept b-frames. Encoder x264 means the CPU is doing the encoding. If you choose, NEVENC then the GPU will do the encoding (for NVIDIA GPUs only).

You will want to stream using an Ethernet cable vs Wi-Fi. It will ensure that you are not running into issues such as distance from your PC to your router, wifi card issue in your PC or just low bandwidth limitations on your Wi-Fi adapter.

  1. Hi

    So I’ve follow your set up guide and I’m still experiencing a laggy stream. I messaged originally on Reddit. I’ve including my mixer so you can see for yourself if that helps

    1. If you follow this and still have a laggy stream, you’ll have to check your upload speed and your log files for errors and to see if you are losing frames due to network or encoding.
