We suggest using a sole-colored cloth/screen or a painted wall as a background behind you so that you can replace it with Man圜am’s Backgrounds or apply Chroma key to it.
CHROMA KEY IMAGE SKIN
Green and blue backgrounds are more commonly used because they differ most distinctly in hue from all human skin colors and therefore you will have less interference when keying a person on screen. The chroma key feature will not work without a green (or blue) screen placed behind a person or an object in the frame. You can pick any default Man圜am background or add your own custom image. This feature allows you to replace your background without a physical green screen. Replace background (without a green screen) To enable Background blur, navigate to the Chroma key tab, and enable the feature as shown below.
