Livestreaming with OBS

Test Internet Speed

Ensure a smooth livestream by conducting a speed test on your streaming device. We recommend a UPLOAD speed of over 10Mbps to prevent choppiness or disconnections during your live stream.

If your speed is below 10Mbps, adjust your OBS settings by reducing the resolution. Double-click on your camera source to make the change.

Verify OBS and Device Connections

Confirm that OBS is running on your computer and check that your camera and audio sources are properly connected. You should see your camera feed and a lit green indicator for your audio source.

Helpful Reminders:

  • Keep your computer and phone charged during the live class.
  • If using your phone as a camera, activate "Do Not Disturb" or airplane mode.
