Speed Ramping

Speed Ramping is a variant of Variable-Speed Remap. 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: Use a continuous monotonic source-time map with explicit rate ramps; place the intended action inside the chosen speed segment and preserve order.

Speed Ramp: Playback speed changes within one continuous action, slowing a chosen instant and returning to a faster rate. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Reach for Speed Ramp when you need this effect: Playback speed changes within one continuous action, slowing a chosen instant and returning to a faster rate.
How it works
Use a continuous monotonic source-time map with explicit rate ramps; place the intended action inside the chosen speed segment and preserve order.
Common mistakes
If the result does not follow this rule, it is not this technique: Use a continuous monotonic source-time map with explicit rate ramps; place the intended action inside the chosen speed segment and preserve order. Do not change multiple variables at once so the effect becomes unreadable.

How to read this page

Speed Ramp 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.
