Prompt rule: Scale only the chosen subject about a declared contact anchor; keep environment transforms fixed and recompute shadows.

Scale Shift: A body's size changes relative to an unchanged room, requiring new contact and shadow relationships rather than a camera zoom. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Reach for Scale Shift when you need this effect: A body's size changes relative to an unchanged room, requiring new contact and shadow relationships rather than a camera zoom.
How it works
Scale only the chosen subject about a declared contact anchor; keep environment transforms fixed and recompute shadows.
Common mistakes
If the result does not follow this rule, it is not this technique: Scale only the chosen subject about a declared contact anchor; keep environment transforms fixed and recompute shadows. Do not change multiple variables at once so the effect becomes unreadable.

How to read this page

Scale Shift is one technique in Optical Effects. 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.
