OBS Studio is a free screen recording software. You can use it to capture anything being shown on your computer screen.
Initial OBS Setup
Step 1: Install the OBS Studio app and launch it.
Step 2: Next review the OBS Studio app permissions. Enable screen recording permissions under Open Screen Recording Preferences.
On an Apple computer, under System Systems, Privacy & Security, then Screen & System Audio Recording, toggle the switch for OBS to on. Revisit the permissions under the menu bar under OBS then Review App Permissions.
Step 3: Important: Make sure to choose to “Optimize just for recording, I will not be streaming”.
Revisit this settings under the Tools menu. Go to Tools then Auto-Configuration Wizard to switch optimization for streaming, recording, or virtual camera. The virtual camera allows you to use the OBS scene output as a webcam in other software such as Zoom.
Step 4: Click Next and choose the Base Canvas resolution and frame rate.
You can choose the highest resolution your monitor supports and it can scale down. In this case I selected 5120 x 2880.
Or choose either 7680 x 4320 (8K), 3840 x 2160 (4K), 2560 x 1440 or 1920 x 1080 (HD) resolution depending on your monitor’s resolution. YouTube can handle all of these resolutions.
Choose your desired frame rate: 60 or 30 frames per second (fps).
On an Apple computer go to System Settings, then Displays, then click the toggle to show all resolutions. Choose your desired monitor resolution.
On a PC go to Start > Settings > System > Display. Look for the Display resolution drop-down menu. Select the resolution you want from the drop-down menu.
Step 5: Under the Scenes column in the lower left of the OBS app click the plus symbol to create a new Scene. Give it a name.
Step 6: Under the Sources column click the plus symbol and select (MacOS) Screen Capture. It will read as MacOS screen capture for an Apple computer.
Method: Display Capture (or choose Automatic on PC)
Display: (Name of your Display) (Ex: StudioDisplay: 2560x1440)
Step 7: Disable any built in mics if you don’t wish to use them. This is the Mic/Aux input that you can choose to mute.
Step 8: Change the scale of the window in the top of the OBS app to fit the screen. You can scale the capture window by grabbing and dragging the corners on the red rectangular selection box.
Step 9: Settings for Recording.
Click the Settings menu. Click the Output menu on the left column.
