                Recording videos with OBS
              
          

        

      

        

  

      

    
Why OBS? It's free and Twitch streamers have proven it is quite configurable and reliable.


Configuration


    

  1. Download OBS (Mac, Linux, Mac) from: https://obsproject.com/download
    2. 

  2. Install and Launch OBS.
    3. 

  3. Create an Scene
    4. 

  4. Add Display Capture and Audio Capture
    5. 

  5. Open the Settings window and select Output, then Recording, select mp4
    6. 

  6. Still under Settings, Hotkeys tab, I recommend adding a hot key to start and stop recording.
    7. 

  7. Close Settings window.
    8.
