What it does
An OBS Studio video filter that perspective-corrects an angled webcam, such as a handcam filming your mouse from the side. Mounting the camera at an angle keeps your monitor from blocking its view of the mousepad, and the filter turns that skewed picture back into a straight-on one. You drag four corners onto your mousepad in a small browser editor, and the filter warps that area so it fills the output.
