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 rain trajectories coherent with wind and gravity, respect shelter occlusion, and tie wetting and ripples to exposed surfaces. Streak appearance follows the capture reference rather than frozen glitter.
Rain: Falling droplets form moving streaks and interact with surfaces through splashes, wetting and reflection. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Reach for Rain when you need this effect: Falling droplets form moving streaks and interact with surfaces through splashes, wetting and reflection.
- How it works
- Keep rain trajectories coherent with wind and gravity, respect shelter occlusion, and tie wetting and ripples to exposed surfaces. Streak appearance follows the capture reference rather than frozen glitter.
- Common mistakes
- If the result does not follow this rule, it is not this technique: Keep rain trajectories coherent with wind and gravity, respect shelter occlusion, and tie wetting and ripples to exposed surfaces. Do not change multiple variables at once so the effect becomes unreadable.
How to read this page
Rain Effect 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.
Prompt versions
Same technique, different prompts. Version A is the latest prompt; older versions are the exact prompts that kept clips were made from. Each version shows every model that used it.
Version A · latest：Courier fastening a canvas bag · bus shelter
Version A · Scene of this version (English, verbatim)
A courier fastens a canvas bag beneath a bus shelter during a shower.
