Dolly

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.

Dolly and zoom run in opposite directions so the subject keeps its size while the background stretches or compresses.

This is for a motion graphics video. In [scene], use a "Dolly Zoom" (also called the vertigo effect, a zolly or a Hitchcock zoom): the camera travels toward or away from the subject while the lens zooms the opposite way.
The subject should hold exactly the same size in the frame while the background stretches away or closes in behind it — if the subject changes size, it is only a dolly or a zoom.
Run it over [duration] at an even, deliberate pace so the warping of the space is what the viewer notices.

The camera flies backward and upward from a close subject, widening to show surroundings.

This is for a motion graphics video. In [scene], move the camera with a "Pull-Back Reveal" (also called a dronie or pull-away): it starts close on the subject, then flies backward and upward away from it.
The subject should shrink in the middle of the frame while more and more of its surroundings come into view, until the whole setting is shown — an ordinary dolly out only steps back a little at eye level.
Run it over [duration], starting gently and widening steadily so the scale of the place is the payoff.

The camera passes through a gap such as a window or beams, then reveals the subject beyond.

This is for a motion graphics video. In [scene], move the camera with a "Fly-Through" (also called a fly-through reveal): it travels forward through a narrow opening, such as a window, a doorway or a gap between beams.
The opening should fill the view and hide most of what lies beyond, then rush past the edges of the frame as the camera clears it and the subject on the far side comes into full view — a plain dolly only moves closer to something already in the open.
Run it over [duration] as one continuous forward move, and settle gently once the subject is revealed.

An aerial camera travels forward above a landscape, then often rises to open the scene behind.

This is for a motion graphics video. In [scene], move the camera with a "Fly-Over" (also called an aerial shot): it travels forward high above the scene, looking down on it.
Everything should stream toward the camera and slip away beneath the bottom of the frame as it is passed over, then the view lifts to open up the scene that lies beyond — a dolly at eye level only brings things closer, it never passes over them.
Run it over [duration] at a smooth, steady speed, like a drone gliding forward.
