Rapid Zoom In
A rapid zoom in snaps focal length faster than a polite crash, almost a cut, the world tightening in a few frames, then a hold. The camera body does not travel.

Narrative function
No time for a dolly. Emphasis as a weapon: a face, a gun, a sign.
The snap is so short it can read as an axial cut with a trail of glass. A crash zoom is already fast; this is faster than a polite crash.
If you can feel a leisurely enlarge, it is not rapid. If the body moved, you dollied.
How it works
Locked sticks or a locked handheld brace, zoom thrown to the end stop in a fraction of a second, then hold. Wide to tight.
No parallax. Prompt: Rapid zoom in on [Subject], faster than a polite crash, almost a cut, the world snapping tight.
When to use it
Use it when a fact must arrive as a snap, not a walk. Do not use it on every line.
Compared with similar shots
Crash Zoom In is the punch that is still readable as a zoom. Rapid is nearer a cut.
YoYo Zoom comes back out. A true cut would have no optical trail.
In film
Hot Fuzz weaponizes snap zooms as punctuation. Kill Bill uses snap zooms as comic and violent emphasis.
Grammar: almost a cut, then a hold.
Prompt it
Faster than a crash, then hold. Still: Rapid zoom in on [Subject], faster than a polite crash, almost a cut, the world snapping tight.
Video: Extremely fast zoom into [Subject], nearly a cut, then a hold. Body still.
Forbid wheels.
What usually goes wrong
The usual wrong cousin is a dolly-in or a slow crash. The tell: parallax, or a leisurely enlarge.
The fix: locked body, snap to tight in a few frames, hold.
