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!

Maintained for the current release version of OBS

Inspired by caharkness's Magic Window
