Zoom and Follow
Have you ever needed to zoom in on your screen to show some fine detail work, or to make your large 4k/ultrawide monitor appear less daunting on stream? Zoom and Follow for OBS Studio does exactly that, zooms in on your mouse and follows it around. Configurable and low-impact, you can now do old school Camtasia zoom live!
