Zoom Transition

An instant jump to a tighter frame of the same subject along the same line, with no zoom travel between the two sizes.

This is for a motion graphics video. In [scene], use a "Punch In" (also called a cut-in or axial cut): cut instantly to a tighter frame of the same subject along the same line.
Show no zoom travel between the two sizes and let the action carry on without skipping time — that is what separates it from a zoom and from a jump cut.
Fit it into [duration], and put the cut on the word or detail that should get the emphasis.

The lens focal length changes so every layer scales by the same ratio without any parallax; unlike a dolly, the camera does not travel.

This is for a motion graphics video. In [scene], use a "Zoom" (also called a zoom in or zoom out): the lens changes focal length while the camera stays where it is.
Everything in the frame should grow or shrink together by the same ratio, with no depth shift between near and far layers — that is what separates it from a dolly.
Run it over [duration], and ease into and out of the move so it does not start or stop abruptly.

Two vertical or horizontal edges move from the center to the sides (or the reverse) like opening barn doors.

This is for a motion graphics video. Join two shots in [scene] with a "Barn Door Wipe" (also called barn doors, a split or a center split): two edges part from the middle of the frame toward the sides and uncover the next shot, like barn doors opening.
Keep both shots still while the edges travel — unlike a push, nothing slides out of the frame, and unlike a plain wipe the reveal starts in the middle and runs both ways at once. For the closing version, bring the edges in from the sides to meet in the middle.
Run the transition over [duration], with both edges moving at the same pace.

A radius sweeps around the center of the frame like a clock hand, uncovering the next shot behind it.

This is for a motion graphics video. Join two shots in [scene] with a "Clock Wipe" (also called a radial wipe): a line sweeps around the center of the frame like a clock hand and uncovers the next shot behind it.
Start the hand at the top and take it once around at a steady pace, with both shots staying put — unlike a plain wipe, the edge turns around a point instead of travelling across the frame.
Run the full turn over [duration].

A cut between two tonally opposite images to emphasize the difference between them.

This is for a motion graphics video. Join two shots in [scene] with a "Contrast Cut": cut straight from one image to its tonal opposite.
Make the two sides differ as much as possible — bright against dark, small against large — and hold each long enough to compare; unlike a smash cut the point is the comparison, not the shock.
Fit both shots into [duration], and put no transition effect on the cut.
