Dust Motes
Countable slow-moving particles scatter a beam toward the lens without forming a continuous cloud.
Selected recipe
Particles
Particles is a variant of Visible Volumetric Dust. It retains its own complete execution recipe.
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: Show sparse, non-emissive particles at varied scene depths under directional illumination. For the selected variant, preserve either quiet ambient drift or one declared emission event with coherent forces, fading outside the light and respecting solid-object occlusion. Do not substitute a continuous fog sheet or a camera-fixed texture.
Dust Motes: Countable slow-moving particles scatter a beam toward the lens without forming a continuous cloud. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Display air and time with minimal movement in quiet old space.
- How it works
- Establish a particle visible area with a dark background and directional light to keep the main object readable./Choose static floating or single launch variants with air drift, gravity, settling and observation periods specified respectively./Check out-of-focus and solid occlusion at different depths, not allowing all particles to travel at the same speed or stick to the lens.
- Common mistakes
- Huge uniform snowflakes filled the picture./The grain is bound to the lens coordinates.
How to read this page
Dust Motes is one technique in Atmosphere. 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 gothic drama: entering her dead great-aunt's shut-up parlor for the first time, a young heiress taps the dusty velvet cloth draped over a table, and a sparse cloud of motes rises through the window's backlight.
