Selected recipe

Dolly Zoom

Vertigo Effect is an alias for Dolly Zoom in the Dolly Zoom / Vertigo family. This route selects the family-default recipe.

Free sample card: the complete recipe is open on this page

Free short AI video prompt

A starter line you can copy. The full timed recipe, still-image and production prompts are on the shot card.

Prompt rule: Couple camera translation with the opposite focal-length change. Hold the selected subject height within a designed ±5% tolerance while background scale changes relative to it; never fake this with elastic geometry.

Dolly Zoom: A dolly zoom pairs forward travel with zooming wider, or backward travel with zooming tighter, to hold subject size while changing perspective. Keep the subject readable; motivate camera and light.

Technique guide

When to use
While maintaining the emotional center of the character, create spatial pressure or sudden estrangement.
How it works
Select the main subject measurement frame, arrange a background significantly farther than the subject, and lock the actor's position. Move according to the distance and focal length linkage curve, measure the subject's height frame by frame, and check the relative change of the background.
Common mistakes
The subject and background are scaled proportionally together. The portrait is significantly reduced but is still called compensating zoom.

How to read this page

Dolly Zoom (Vertigo Effect) is one technique in Camera Movement. The definition states the single mechanism the frame has to show. The technique guide covers when to use it, the steps, the usual mistakes, how it differs from the neighbors, and what a successful take looks like.

The clip above is one reading, made with a third-party video model. Another model, or the same model on another day, can land on a different frame. It is an example, not a promise that a prompt will match it.

The free short prompt is a starter sentence. The shot card is the timed recipe: scene, start and end frames, action, light, and color. Three sample cards are free on the site. The rest are part of GrokCine Pro. A second name for the same shot keeps its own URL and points back at this definition.

When you write a prompt, keep the one mechanism in the definition, then name the subject, the motion, and why the light is there. Do not stack a neighboring technique into the same sentence. If the name or the example is wrong, send this page's URL from the contact page.

Prompt versions

Same technique, different prompts. Version A is the latest prompt; older versions are the exact prompts that kept clips were made from. Each version shows every model that used it.

The whitebox in the player above is built from this shot card's prompt. The clips come from several models, and not all of them from this prompt, so their scenes and moves can differ from the whitebox.

How to shoot it

  1. 1Stand the print jogger on a mark in the aisle between the pigeonholes of uncut posters, arms at their sides, with the drawer bank 5 m behind.
  2. 2Lay straight track toward the camera. Tape the start mark 2 m and the end mark 4 m from the print jogger, measured to the camera's film plane.
  3. 3Put the lens at the print jogger's eye height and keep the head level. The eyes then stay on the frame's centre line for the whole move, so nothing needs tilting.
  4. 4Full-frame 40–80 mm zoom framed 16:9, f/5.6, 1/48 s, 24 fps, white balance 4300 K. A constant-aperture zoom keeps the exposure from pumping as it zooms.
  5. 5Hold the first frame for 1 s. From 1 s to 7 s, pull back and zoom in together, hitting each row of the paired marks on the second. Hold the end frame to 8 s.
  6. 6Pull focus with the dolly: the focus marks are the dolly marks.
  7. 7Light it with a soft 5000 K source hung above the aisle in front of the print jogger and small 3000 K reading lamps behind.
  8. 8On playback, the print jogger's height stays within ±5% from 1 s to 7 s, the drawers grow about 1.56 times, and no straight line bends.

Paired marks

Dolly and zoom hit each row together. The dolly speeds up over the first second and slows over the last; the zoom follows at 20 mm per metre.

TimeDollyZoomFocus
1 s2.0 m40 mm2.0 m
2 s2.2 m44 mm2.2 m
3 s2.6 m52 mm2.6 m
4 s3.0 m60 mm3.0 m
5 s3.4 m68 mm3.4 m
6 s3.8 m76 mm3.8 m
7 s4.0 m80 mm4.0 m

The rule

focal length (mm) = 20 × distance (m)

The print jogger's distance doubles (2 → 4 m) and so does the focal length (40 → 80 mm), so the print jogger's size holds. The drawers only go from 7 m to 9 m away, 1.29 times, against the same doubling, so they come out 1.56 times bigger.

What the whitebox adds

The prompt leaves these open, so the whitebox picks them: the print jogger is 1.76 m tall with eyes at 1.64 m and stands with arms at their sides, as in the clip; the aisle is 2.8 m between the shelf fronts and the ceiling 3.3 m high; the dolly takes 1 s to reach speed and 1 s to stop. The prompt's light still mentions a worktable, a word left from an earlier version of the scene; there is none in the clip, so the soft top light hangs above the aisle in front of the print jogger. Wardrobe, faces and textures are left out, as in any whitebox.

Recipe

8 seconds · single take

Scene
A print jogger in a tan apron stands before pigeonholes of uncut posters in a letterpress hall, with the racks several metres behind.
Initial state
Camera 2 m from print jogger, 40 mm lens, eye height; print jogger torso centered and storage 5 m behind.
Action / timeline
During seconds one to seven retreat from 2 m to 4 m while zooming from 40 to 80 mm, adjusting focal length to hold print jogger height within a project target of 5 percent. Pull focus with distance. Drawers grow relative to the fixed-size person; no object warps. The pigeonholes, posters and drawers are fixed furniture and never slide, open or move; only perspective changes.
End state
Print jogger remains near starting image height while distant storage appear larger behind.
Lighting
A soft 5000 K source above the worktable gives a cool-neutral key relative to 4300 K white balance. Small 3000 K reading lamps stay warm behind. Flag paper reflections and keep labels readable without exposure pumping.
Color
A tan apron and uncut poster paper sit before deep pigeonholes. Shadows remain cool charcoal, skin midtones retain subdued warmth, and paper highlights stay ivory with gentle rolloff. Moderate contrast, open blacks and no artificial aged-film scratches.
Assembly / finishing
Uneasy psychological-drama look; a smooth, continuous move.

Still-image prompt

For image-to-video: make the opening frame with an image model, then animate it. A still alone cannot show the motion.

Dolly Zoom: first frame for image-to-video
Output: one 16:9 still image showing only the opening moment.
Scene: A print jogger in a tan apron stands before pigeonholes of uncut posters in a letterpress hall, with the racks several metres behind.
Frame: Camera 2 m from print jogger, 40 mm lens, eye height; print jogger torso centered and storage 5 m behind.
Camera: 40 mm on the zoom lens at the initial setting; f/5.6; focus: Follow eyes from 2 m to 4 m
Lighting: A soft 5000 K source above the worktable gives a cool-neutral key relative to 4300 K white balance. Small 3000 K reading lamps stay warm behind. Flag paper reflections and keep labels readable without exposure pumping.
Color: A tan apron and uncut poster paper sit before deep pigeonholes. Shadows remain cool charcoal, skin midtones retain subdued warmth, and paper highlights stay ivory with gentle rolloff. Moderate contrast, open blacks and no artificial aged-film scratches.
Avoid: Subject and background scaling together; Shelves melting or warping; The jogger changing size; A cut in the middle of the move

Production prompt

Paste it into a video model as is: the technique comes out of one generation, with no editing or post work.

Dolly Zoom: AI video prompt
Output: one 8-second clip, 16:9. Generate it as one continuous shot with no cuts.
Technique: A dolly zoom: the camera moves back while zooming in, so the person stays the same size but the background seems to swell and loom behind them.
Scene: A print jogger in a tan apron stands before pigeonholes of uncut posters in a letterpress hall, with the racks several metres behind.
Start: Camera 2 m from print jogger, 40 mm lens, eye height; print jogger torso centered and storage 5 m behind.

Pull focus with distance. Drawers grow relative to the fixed-size person; no object warps. The pigeonholes, posters and drawers are fixed furniture and never slide, open or move; only perspective changes.
End: Print jogger remains near starting image height while distant storage appear larger behind.
Camera: 40-80 mm zoom; simultaneous retreat 2→4 m and zoom 40→80 mm; f/5.6; focus: Follow eyes from 2 m to 4 m
