Creating flashy transitions stylizes your edits and keeps the viewer interested in the content of your video. This tutorial goes into depth on how to create a custom transition where two videos are merged seamlessly when panning over an object which covers the frame.
Key takeaways from the video:
- Layering video makes it possible to use masks in order to show both videos at the same time
- The four point polygonal mask tool (rectangle) is found under the Effect Controls>Opacity>Four Point Polygonal Mask
- Masks can be adjusted and keyframed
- Right and Left arrow keys can be used to move forward and backward (respectively) in the timeline
- The toggle animation tool (stop watch) creates keyframes which can then be manipulated over the span of different frames throughout the video
