The camera jumps forward or back along the same axis for emphasis and shock.
A surprised expression, or approaching in two steps at a product reveal.
Generate a start frame separately that keeps the center of the frame and only enlarges the subject, or use crop+scale when editing. 1080p footage gets mushy past 120% enlargement, so generate anything beyond that separately.
Three-shot sequence, camera fixed on the same axis and centered on a lone lighthouse at dusk: Shot 1 wide, the lighthouse small in the distance; hard cut to Shot 2 medium, the lighthouse larger; hard cut to Shot 3 tight, its glowing lamp fills the frame. Same sky color and center position, 1.5 seconds each, a bass hit on every cut.
