o you have an overlay for your stream and you're ready to add a new source for your webcam or some other display. Awesome! Just one problem - how can you adjust just 1 side of the window? Every time you click and drag on one of the sides, the entire source gets resized! Never fear, you need to use the magic of cropping the source.
Follow the steps below to crop just one side of the source:
1. On your keyboard, press and hold the Alt key.
2. Click on the red square for the side that you want to adjust.
3. While still pressing the Alt key, drag the red square to your preferred position.
You can do the same thing to any of the sides of a source window. Be sure to lock the source once you have your desired size.
