Transition in still image or video overlaying on another video?
Just starting out with Hitfilm and really enjoying it so far.
I had a question of how to do a transition effect in making an image or video appear as it is overlaying over another video as the background.
As a video example, at 3:52 of this video: https://youtu.be/JxiPHBQBeAI?t=232 it does a block swipe effect to bring in another image and at 4:48 https://youtu.be/JxiPHBQBeAI?t=288, it does something similar with circular bubble effect. I imagine you should be able to use a variety of shapes to do something similar.
I was wondering how I would be able to use an effect like that to make an image/video appear or disappear over another one.
