Readjusting the size of the screen can also fix the aspect ratio without fiddling with resolution settings. There are two ways you can do this: by applying the Crop/Pad filter or by using a keyboard command. If the image is too large for the OBS screen, you can crop it to a compatible size. Here’s how to do it: 1. Scroll to the bottom of the screen and right-click on the “Sources” box. 2. A pop-up window will appear. Click “Filter.” 3. You’ll be redirected to a new window. Click on the plus icon in the bottom-left corner to add the “Crop/Pad” filter. 4. Adjust the cropping parameters to fit the screen. Click “OK” when done. The other method works great if the image is too small. You can use your cursor to stretch the corners to fit the screen and eliminate Black Bars. It’s super easy: 1. The screen capture is outlined with red lines. Click on the little red circles to adjust the size. 2. Press the “Alt” key and hold it while you move the cursor. For Mac users, hold the “Options” key. 3. Stretch the top, bottom, sides, and corners of the image to adjust the aspect ratio manually. However, while this is the easiest way to fix the aspect ratio, it’s also the least effective. Stretching the image can sometimes distort it, especially when it comes to faces and geometrical shapes. For optimal results, it’s better to stick to changing the resolution settings.
