OBS Studio Configuration

Once you open the program, it might have a popup window called "Auto-Configuration Wizard".

If you tap on "Yes".

Usage information:

  1. Optimize for streaming, recording is secondary.
  2. Optimize for recording, I will not be streaming.

I chose option 2.

Video settings:

  • Base (Canvas) Resolution: Use current 1366x768
  • FPS: Either 60 or 30, but prefer 60 when possible.

Those were the default values.

Final results:

  • The program is now executing a set of tests.

Nothing to do here. Just wait for the test to be completed. Then "Apply Settings".

Adding Screen, Camera and Audio

Add the Screen:

  • Inside the Sources window.
  • Tap the plus sign.
  • Select Screen Capture
  • Create new.

A popup window shows:
