Base (canvas) resolution

OBS's working resolution — usually your monitor's native size. The output resolution is what viewers get after downscaling.

  • Resolution

    The pixel dimensions of your stream — 1920×1080 (1080p) or 1280×720 (720p). A crisp 720p60 beats a blocky 1080p60 on low bitrate.

  • Downscaling

    Rendering your stream at a lower resolution than your monitor (1440p screen → 1080p stream). Lanczos is the sharpest OBS filter for it.

  • OBS (Open Broadcaster Software)

    The free, open-source app most streamers use to broadcast — it captures your game, webcam and mic, mixes them into scenes, and sends the stream to your platform.
