Rapid Zoom In

The lens closes fast enough to feel like a decision made in front of you. It is the sound of somebody spotting something.

It sits in a useful gap. A slow zoom hides itself and a crash zoom shouts, so a rapid zoom moves with intent and still leaves the audience able to follow the frame.

It has a tone that the slower version does not. The speed is visible, so the camera is openly reacting, and the audience reads a point of view behind it.

The lens runs its travel in roughly a second, then settles. The settle is part of the move, because a rapid zoom that stops dead reads as a crash.

A small amount of ease at the end sells it as an operator rather than a machine. The shot usually holds on the tight frame afterwards, so the audience has somewhere to land.

A small ease at the end is what separates it from a snap. The lens decelerates over the last part of its travel and arrives rather than crashes.

The shot normally holds on the tight frame for at least a beat afterwards. Cutting immediately on arrival turns the move into a transition and wastes the size it just reached.

Use it when a character notices something, when a scene turns, and in comedy and action where the camera is allowed to have opinions.

Avoid it in a scene playing for stillness. The speed announces the camera, and a quiet moment does not survive that.

It also works as a cut substitute. Two beats that would otherwise need a wide and a close can run in one take, with the zoom doing the work the edit would have done.

A crash zoom in snaps under a second with a hard stop and usually some radial blur. A rapid zoom in takes about a second and settles. If the frame arrives with a thud, it is a crash.

The difference is duration and landing, so state both. Fast lens change over about a second, settling on the tight frame, is a rapid zoom every time.

Models collapse the middle speed and give you either a creep or a snap. Put the duration in words, since about a second is the whole definition.

The second failure is forward travel instead of a lens change. Say the camera body does not move.

A third problem is a zoom with no hold. Say the shot settles and stays on the tight frame, or the model runs the move and ends the clip on the same frame.

A fourth problem is a start frame that is already tight. Give the wide size as well as the close one, or there is not enough travel for the speed to register.
