In this part of the video, the speaker provides a step-by-step guide on setting up a green screen using a video capture device. They begin by adding a new scene named “green screen” and then proceed to add a source, specifically a video capture device from which they select their camera, in this case, a Cam Link 4K. Once the camera is set up, the speaker appears on screen with the green screen in the background.
To remove the green screen, they right-click on the video capture device source and navigate to the “filters” option. They then add an effect filter called “chroma key,” which makes the green background transparent. Various settings within the chroma key filter allow adjustments, including the key color type (green or blue), to refine the transparency effect. The speaker explains the common use of green or blue screens due to their dissimilarity to skin tones. They also demonstrate adjusting additional settings like key color spill reduction to handle any green halo effect around the edges.
