If using variable bitrate, the actual bitrate will vary depending on the complexity of the scene. Tells the video encoder (x264) to target this bitrate in kbps. 5 is usually the "safest" value for most situations. Recommended: Varies depending on resolution/fps relative to the bitrate.If you get undesirable pixellation on higher motion, it generally means you should turn down this value until it stops, or increase your bitrate. If you have a high bitrate relative to your resolution/FPS, you can safely set this higher, but if you have a lower bitrate relative to your resolution/FPS, higher values will cause pixellation in higher motion scenes, so the value needs to be lowered. Generally the value you should set this to depends on your bitrate, resolution, and FPS. This value is not used and disabled if using CBR (constant bitrate). This is only used with variable bitrate, and determines how the video encoder should spend bits for quality. When using variable bitrate, this controls the CRF (constant rate factor) parameter in x264 (10 is CRF 22, 0 is CRF 32). Recommended: Generally safe to have on unless you're worried about total bandwidth usage.The quality cost of CBR is quite low and the issues it can fix such as viewers complaining of lag when there are no dropped frames can make this worth using, and it also eliminates the burden of having to pick an appropriate quality value. This results in a less spiky (bandwidth wise) stream, but will also cause both you and your viewers to consume more total bandwidth as scenes with no motion at all will still use the specified bitrate.ĬBR can help with QoS/latency issues caused by variable bitrate as TCP is not well designed for variable bandwidth.
The "quality balance" setting will have no effect as the quality will be determined entirely by your bitrate, and x264 will try to ensure your stream goes out at exactly at bitrate specified. This will set x264 to use constant bitrate rather than variable bitrate. For online streaming this is the recommended encoder. Each of the encoders has different abilities with x264 being probably the most stable one. If available on your system you can switch between the x264 encoder, the Intel Quick Sync encoder and the Nvidia encoder included in newer gen graphic cards by nvidia. OBS supports more than just the standard CPU encoding using x264. Video Encoding Encoder (x264/Quick Sync/Nvidia NVENC) For all other settings, there is an official OBS settings estimator. When configuring encoding, make sure to test your available bandwidth first, typically using a site like. Each streamer should experiment with their own settings.)
