Prompt rule: Derive echoes from actual prior frames, localize them to the moving element, and keep the current image strongest.
Echo Print: A delayed weaker copy of prior motion remains visible behind the current pose, producing a time-offset afterimage. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Reach for Echo Print when you need this effect: A delayed weaker copy of prior motion remains visible behind the current pose, producing a time-offset afterimage.
- How it works
- Derive echoes from actual prior frames, localize them to the moving element, and keep the current image strongest.
- Common mistakes
- If the result does not follow this rule, it is not this technique: Derive echoes from actual prior frames, localize them to the moving element, and keep the current image strongest. Do not change multiple variables at once so the effect becomes unreadable.
How to read this page
Echo Print is one technique in Optical Effects. 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.
