 It is very easy to create a scene like this where you show a camera view and a presentation in the same screen. Check out my previous video if you don't know how to do this. But what if you want to show your camera view inside a shape like this? In this video, I'm going to show you how to create such a scene. Let's get started. To achieve this effect, we are going to use an image mask. An image mask allows you to manipulate the shape of a media layer in OBS. In this example, we will add a circular image mask to our camera. What is an image mask? An image mask is simply an image made up of two colors, black and white. The black area indicates the part that you want to hide and the white area indicates the part that you want to show. You can use any program to create the image mask. I'm going to use a popular website called canva.com to create my image mask. I start by creating a design and I will choose custom size because I want to make sure that the size of my image matches my camera resolution. And since my camera is a full HD resolution, that resolution is 1920 by 1080 pixels. Click on create a new design and this is my image area. First, I will set the background of this image to black. Next, I will go to elements and choose a circle, resize the circle, center it and color it white. And my image mask is done. All I have to now do is download it. Next, switch to OBS and select the scene that has your web camera as a source. In my case, I have this camera view Nikon. Right click on it and choose filters. Click plus sign and choose the filter image mask blend. Give any name to your filter. I will leave it as it is and click OK and click on the browse button and select the file that you had just saved from canva and click open. Now your image is masked with the circle shape. Click close and this is how it will appear. If you have another scene with the same source, the image mask will automatically apply to that scene too like this. If you want to remove the mask, right click on the filter and either disable it or delete it by clicking the minus sign. I hope this short tutorial gave you an idea how to use the image mask to create interesting shapes for your own video source. I wish you all the best.
