OBS does the same: The background is a source. Then he paints some animals in front of the house. The painter starts by putting some background color on it. But it will use even less system resources.Ībout the canvas: think of OBS as a painter who paints his paintings upon a canvas. In this case, it might be wise to also reduce canvas size and webcam resolution to 720p, because without compositing of multiple sources you can reduce the resolution of the canvas and the webcam to the output resolution with no visual impact.

If your machine isn't powerful enough to encode this 1080p video, it may be necessary to reduce the output resolution, for example 720p, because reduced resolution means less CPU requirement in the video encoder. This way, your webcam is never rescaled but output verbatim as it is captured by your webcam device. Set all to 1920x1080: canvas size, output size, webcam size. If you don't need all that and just want to capture a webcam and just want to stream exactly that webcam with exactly this one webcam source without any added source or overlay, you don't need all this rescaling. Game streamers use this feature to create all their fancy overlays and widgets.įor all this flexibility it is possible and important to be able to rescale stuff at various stages. This overlaying of multiple sources is called compositing.

For example, you can include some tiny source in some corner that displays added information. OBS is able to include more than one such source into an output video. Keep in mind that OBS is a universal streaming and recording application that is able to do much more than just capture one source (for example your webcam) and stream exactly that webcam.
