Masks are used to “Mask” out or hide specific parts of an element by using an image to dictate what part to hide. We typically use these for webcams to give them a seamless appearance with our webcam frames. Here’s how you use them:
1. Add your webcam source in OBS.
2. Click on Filters and then click on “+” at the bottom left corner.
3. Select “Image Mask/Blend”.
4. Name the source.
5. Click on “Browse” next to “Path” to choose the mask.
6. Under “Type” select “Alpha Mask (Alpha Channel)”.
7. Now your webcam should be in the same shape as your mask. In this case – circle shape.
8. Add your webcam overlay for circle shaped camera.
9. Resize the webcam overlay to fit perfectly over your masked webcam source.
10. Make sure to click on webcam and overlay sources holding ctrl, then right click and then select “group selected items”. This way your webcam and overlay will be grouped together and you will be able to move them without messing with the alignment.
11. Enjoy your stream!
