Video settings in OBS are the second stop in the configuration. The settings determine the canvas dimensions (the OBS preview window size), the output dimensions (the resolution streamed to the platform), and the frame rate.

The configuration: in OBS Settings, navigate to Video. Set the Base (Canvas) Resolution to 1920x1080 (the standard reference resolution that lets you scale to lower outputs cleanly). Set the Output (Scaled) Resolution to 1280x720 for entry-tier streaming (this is the resolution actually transmitted to the platform). Set the Common FPS Values to 30 for entry-tier broadcast.

The reasoning behind 720p 30fps at entry tier: the bitrate budget on most entry-tier connections cannot sustain 1080p or 60fps cleanly without frame drops. A clean 720p 30fps stream beats a buffering 1080p 60fps stream on every viewer-experience metric.

The save discipline: apply each change. Restart OBS after the Video settings save (some OBS versions require a restart for canvas-resolution changes to apply correctly throughout the application).
