In most cases you will want to set ‘Main’ as the profile. The slower you set it, the higher the video quality, however the higher the CPU usage is. It will determine how much CPU power you wish to use to render the video. If you want to learn more about keyframes, head over here.ĬPU Usage Preset is only relevant if you’re using software encoding, x264. What this means is that a full video frame will be rendered every 2 seconds. We go into much more detail about how to determine your ideal bitrate in this article about BPP or bits per pixel.įor live streaming you will want to set your keyframe interval to 2. The below table gives you a rough guide on what bitrates to use. Your bitrate will be determined by a number of factors including: Just make sure the platform you’re streaming to supports it. If you have limited upload bandwidth, then VBR or variable bitrate is a good choice. However, the downside to this is that it will require higher bandwidth. Generally speaking CBR also provides the highest visual fidelity, as it will aim to maintain a consistent specified bitrate. CBR or constant bitrate is the most widely used and accepted method. Rate control will determine how consistent or inconsistent your bitrate will be. If you don’t have hardware that support hardware transcoding, or you want higher visual fidelity, then go with the x264 option.

Turning on hardware encoding will reduce the CPU usage, however it can result in slightly lower visual fidelity. Depending on your hardware you might want to enable hardware encoding.
