The new feature allows you to take footage recorded against a green screen (a blue screen will also work) and easily replace the background while keeping the subject. You can adjust the strength of the effect and adjust it precisely with a 4-point mask.

In addition to that, you can now also import images with a transparent background in your project, and also use photos to create a picture-in-picture effect or a split-screen effect in your video projects. Add to this 80 new soundtracks that automatically adjust to fit the length of your video project, adds support for ClassKit so students can deliver assignments easily to their teachers and delivers a few bug fixes along the way.
