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: Use stylized virtual geometry and a continuous close approach through the lip plane by only the declared short distance. Keep teeth topology stable; no fantasy throat tunnel or body horror.

Mouth In: A mouth-in camera advances beyond a portrait so lips and teeth become the surrounding space. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Used for stylized scale changes or visual transitions from outside to inside.
How it works
Establish coherent virtual geometry for the face, lips, and teeth, and define the endpoint depth. Approach along the axis, briefly pause after crossing the lip surface, and do not arbitrarily expand the internal space.
Common mistakes
Eating zoom is mistakenly called penetration Facial deformation or unrelated tunnels appear

How to read this page

Mouth In 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.
