Dolly zoom
A dolly zoom moves the camera toward or away from the subject while zooming the opposite way, so the subject stays the same size while the background stretches or compresses. It is the "vertigo effect" from Hitchcock and Jaws.
The move signals realization, dread or a sudden shift in perspective. In generated video it is a prompted effect; engines with strong scene geometry (Seedance, Hailuo) render the background stretch convincingly when the subject is clearly defined and centered.

One of the 24 camera moves the composer recognises: write "dolly zoom" (or insert it from the Syntax menu), and in Cinema pair it with a Tense tempo and overhead-fall lighting for the corridor shot.
Questions
Can AI video do a dolly zoom?
Yes — as a prompted move; a single centered subject with a deep background gives the clearest effect.
Is a dolly zoom the same as the vertigo effect?
Yes — vertigo shot, zolly and contra-zoom all name the same move. The camera travels one way while the lens zooms the other, so the subject holds its size and the background slides behind it.
Why does my dolly zoom look like an ordinary zoom?
Usually because the background has nothing to stretch. The effect needs a clearly separated subject and depth behind it — a corridor, a street, a landscape — and one slow move per clip with no second action competing.
