Output (Scaled) Resolution refers to the resolution of your output video. If you’re capturing a custom-sized window, you can enter the width and height manually.
If you’re recording your entire screen, for example, and you know your monitor is 1920 × 1080, you’ll select this option. The numbers you see here are the width x height of the video capture. The Base (Canvas) Resolution refers to the dimensions of the window or area that you’ll be capturing for your video. When you click here, you’ll see options for Base (Canvas) Resolution, Output (Scaled) Resolution, Downscale Filter, and Common FPS Values. Whether you’re a new OBS user or a veteran, you can adjust the video settings to capture better quality videos by clicking on the Video option in the Settings window.
