Green screen is a cinematographic technique that allows video editors to add a variety of visual effects to their videos. These effects include : adding virtual backgrounds, superimposing subjects over animated backdrops, placing a subject on another shot and many more. Green screen technology has been widely used in weather and movie industry. But now with the emergence of apps such as the ones below, everyone can use this technology to create engaging clips and presentations. As Do Ink explained “ Green screen technology is used in the movies to make it look like the actors have landed on an alien planet, and it’s used on TV to make it look like your local news announcer is standing in front of an animated weather map. The green screen effect works by combining images from multiple sources into a single video. These images can come from photos or videos in your camera roll, or from the live video camera. “
