The best bitrate for streaming at 1080p depends on a few factors. These factors are your hardware, upload speed, and target frame rate. You should also find out whether your streaming provider allows adaptive and multi-bitrate streaming. This will ensure that your audience has a consistent viewing experience. If the server you are streaming to supports it, a rate of 6,000 is ideal for 1080p at 60 FPS. Try the following settings in order to reach optimal quality: Your Upload Speed: (equal to or greater than) 6 Mbps / 6,000 Kbps Resolution: 1080p Streaming Bitrate for 1080p: 6,000 Frame Rate: 60 Rate Control: CBR Keyframe Interval: 2 seconds X264 Preset: veryfast
