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: Keep one calibrated distortion mapping and optical center across frames; preserve anatomy while letting line curvature follow image position.
Distortions: A specified optical mapping bends scene geometry consistently, instead of adding color fringe or arbitrary liquid deformation. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Reach for Distortions when you need this effect: A specified optical mapping bends scene geometry consistently, instead of adding color fringe or arbitrary liquid deformation.
- How it works
- Keep one calibrated distortion mapping and optical center across frames; preserve anatomy while letting line curvature follow image position.
- Common mistakes
- If the result does not follow this rule, it is not this technique: Keep one calibrated distortion mapping and optical center across frames; preserve anatomy while letting line curvature follow image position. Do not change multiple variables at once so the effect becomes unreadable.
How to read this page
Lens Distortion 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.

A dystopian satire in the manner of 1980s cult cinema: a nervous junior clerk in a dark red suit rides a narrow cylindrical document lift lined with horizontal slats, stepping toward the doorway as the wide lens bows the walls around him.
