![]() This makes your actual network bitrate quite spiky, which can lead to latency issues if queuing occurs on your modem or router. if you have a bitrate of 3000 and a buffer of 6000, x264 could decide that if a scene is complex enough, to use 5000 of the 6000 buffer at once. ![]() If there is a sudden scene change and high motion, it can fill up this buffer at a rate faster than the average max bitrate. x264 will encode everything into a fixed size buffer of this size. Recommended: 70%-80% of your upload speed or 3500kbps (whichever is lower).If you have high upload speed, keep in mind that your viewers will require an equivalent download speed to be able to view your stream, so you probably don't want to go over 3500kbps or so unless you're a partnered streamer and have access to the transcoders (lower resolution selections for viewers). Combined with the audio bitrate, this will determine how much upload you want to be used. If using variable bitrate, the actual bitrate will vary depending on the complexity of the scene. 5 is usually the "safest" value for most situations.īasically tells the video encoder (x264) to target this bitrate in kbps. Recommended: Varies depending on resolution/fps relative to the bitrate.If you get undesirable pixelation 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 pixelation 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). Technical Explanations of most OBS settings General
