If your CPU is not powerful enough, you might choose slow. Set x264 for the encoder, fixed CPU usage preset to slower. The main parameter to change if you have a powerful CPU computer or device is to choose CPU x264 encoding as it provides the most finetuning for quality.In OBS > output, set output mode to advanced. Powerful CPU and/or hardware-encoding capture card as a source? Consider GPU transcoding below if you have multiple applications open on your streaming desktop or a HARDWARE video capture device. If you can not, streamline operations on your single device, so your other application doesn't affect too much CPU/GPU. More than that, you better quit all other applications as they use your CPU and GPU, leading to artifacts in your video output.

Your streaming computer must be dedicated to that for the time of your live stream and recording. Use a different computer for streaming and operations (for a DJ or a video game player, for example) whenever you can Available resources (CPU/GPU), slow encoding, long keyframe period, and network buffer are way more important than resolution and bitrate, which are usually only the settings you are recommended to change by streaming services for their comfort (less transcoding complexity for them means less cost) Nobody knows streaming is late when there is no real-time interaction except for the broadcaster. You should care about latency only if interaction matters more than video quality. The slowest you encode and transmit, the better quality you will get, as you provide more room for the encoder to “ look ahead,” meaning it can look at what's coming before encoding to optimize encoding. It emerged as an offshoot of OBS Studio (in fact, it was called Streamlabs OBS) and has additional paid features in its Prime version (use multistream, overlays, sponsorship, etc).Encoding is like sex: faster is not better. Streamlabs Desktop is another free and open source live streaming software that is available on Windows and macOS, with a separate mobile version for iOS and Android.

OBS is fine to start with, not only because it’s free, but because of the customization options to your liking. OBS is still an interesting alternative if you are looking for greater compatibility with other platforms and software.

Free multistream (simultaneous broadcast on multiple video platforms).

Open source and backed by community support.

Among the main advantages it offers are the following. OBS Studio allows you to fully customize your stream using its built-in features and extended functionality via plugins.
