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: Complete a forward periodic state over the loop interval with matching velocity; omit the duplicated boundary sample.
Infinite Loop: A forward-moving cycle returns to its opening state with matching velocity so the endpoint can repeat without a visible reset. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Reach for Infinite Loop when you need this effect: A forward-moving cycle returns to its opening state with matching velocity so the endpoint can repeat without a visible reset.
- How it works
- Complete a forward periodic state over the loop interval with matching velocity; omit the duplicated boundary sample.
- Common mistakes
- If the result does not follow this rule, it is not this technique: Complete a forward periodic state over the loop interval with matching velocity; omit the duplicated boundary sample. Do not change multiple variables at once so the effect becomes unreadable.
How to read this page
Seamless Loop (Infinite Loop) is one technique in Time & Tempo. 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.

The last shot of a seaside drama: in the shuttered shop of an old toymaker who has died, his little wind-driven whirligig of four painted boats keeps turning on the counter in the draught from the broken window.
