I used to use Final Cut Express on my iMac. It had a feature where you could apply keyframes, I believe it was called, and wire frames. It was possible to move frames around, creating special effects. For example, you could create an effect where a person got it by a car (yes, I know, a morbid example) by moving a frame of a car from, say, left to right, and moving a frame of a person also left to right. The frame of the car would eventually overtake the frame of the person. It's a loose description, but it gave the illusion of the front of the car striking the person. The clip of the car could be edited to the front of the car would be right up against the right edge of the frame, and the clip of the person edited so that the person was right up against the left edge of the frame. Butting both frames together with the car on the left and the person on the right looked like the car and person were making contact.
Does Premiere Elements 2018 have key framing and wire framing?
