You know what a "green screen" effect is, right? It's 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.

Green Screen by Do Ink has all the features you need to make great green screen videos, including:
• use the live video camera, or import prerecorded videos and photos
• combine up to 3 image sources at a time
• scrollable timeline makes it easy to sequence your videos and photos
• add as many image sources to the timeline as you'd like!
• move image sources around on the timeline
• trim videos on the timeline to keep only the parts you need
• easy color picker tool to set the chroma key color
• use the front or back camera
• exposure and white-balance lock
• set an automatic stop time for your video
• rehearse your video before you record it
• preview your video before you save it
• save your recorded videos to your camera roll (and from there to YouTube, email, etc.)
