Green Screen by Do Ink

Green Screen by Do Ink is a featured app because it makes creating green screen videos easy. Sometimes called chroma keying, green screening refers to a special effects technique created by first shooting the main subject with a solid colored background (often green), then replacing the background with a new image or video. DoInk allows for the solid background chroma key color to be a color of your choice. Different backgrounds can be replaced in the same video. DoInk is a paid app that only works on an iPad.
