If Teams inverts the image, there is an easy fix for that: in the whiteboardapp source context menu, under “Transform” you can select “Flip Horizontal”. When it does, it should appear in the list of available cameras: Selecting the OBS Virtual Cemara in Teams settings You might need to restart Teams to recognize this new device. This will start a virtual device that is recognized by the OS as a camera. In the Controls menu (bottom right of the OBS window) start the virtual camera. However, other colors will show just fine: Whiteboard superimposed to webcam One last note: do not use the black, since for some reason black is just treated like white by the Chroma Key filter if the key color is white, and it does not show on screen. Now create a new whiteboard and paint something, whatever you draw will be super-imposed on your video image. Stop the Virtual Camera if you are not able to change the canvas settingsĪlmost done! You should be seeing something like this, where the webcam image is too small as compared to the whiteboard (since it does not have as much resolution as the laptop screen): Webcam video too smallĮasily fixed: drag and drop the picture from your webcam (red rectangle delimiting your video image), until it is where you want it to be. After stopping the camera, you should be allowed to change the canvas size. You can stop it going to the Tools menu, there you will see the “VirtualCam” option that will open a small video that will allow you to stop the camera. If that is the case, it is probably because the Virtual Camera is running. In certain situations, OBS would not allow you to change the canvas size “because there is an acitve video output”. Let’s increase the canvas size using the “Settings” button in the Controls menu, in the bottom right side of the OBS window: Changing the canvas size The reason is because the canvas (the size of the scene) is smaller than the size of the screen, so OBS is only capturing a part of the whiteboard. If you have a high-resolution screen, chances are that not the whole whiteboard will be shown on screeen. Let’s change it to white: Changing key color to white You can see the color selected as Key Color is green. In the Filters window add a “Chroma Key” filter: Adding Chroma Key filter to whiteboardĬhroma Key is the filter typically used in green screens, but we are going to do something different with it, and exploit the fact that it turns the selected color to being transparent. Let us make it so: In the contextual menu for the whiteboard source, that you can access by right-clicking on its name, choose “Filters”. Now your webcam image disappeared, because the whiteboard is not transparent (yet). You can rename scenes as well, I have renamed the “Video Capture Device” to “webcam” (I am a very lazy typer) and put it after (behind) the whiteboard: webcam renamed and placed after whiteboard You can change the order of the sources dragging and dropping items in the source list, putting the whiteboard before the “Video Capture Device” (the first item is in front, the last one behind). Mmh, it looks my face is in front of the whiteboard, but it should be behind. Now you should see something like this: Webcam and whiteboard Now add your webcam as second source (“Video Capture Device”): Adding your webcam as second source Click the plus sign below the source list, and add a “Window Capture”: Add the whiteboard as sourceĬall it “whiteboardapp” (or anything else you like), you can leave the other options as they are: Whiteboard scene properties Now we will add our first souce to the scene: your whiteboard. To create a scene hit the plus sign below the scene list at the bottom left of the OBS window: Create a scene The first thing we will do is creating a scene, which is a set of sources. Disclaimer: I am a complete noob with video, so if you read this and have some advise for me, happy to hear it! I finally made it work using Open Broadcaster Software, a tool that can combine videos from different sources into one. I have been wanting for some time to be able to whiteboard in Teams calls without losing my video image, kind of something like this: Our goal
