Selected recipe

Anamorphic Flare

Anamorphic Flare is a variant of Source-Linked Lens Flare. 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: Tie flare geometry and intensity to the light source and its occlusion; preserve the chosen optical subtype rather than applying a fixed overlay.

Lens Flare: Stray light inside the imaging optics creates source-dependent ghosts or veiling glare that changes when the source is blocked. Keep the subject readable; motivate camera and light.

Technique guide

When to use: Reach for Lens Flare when you need this effect: Stray light inside the imaging optics creates source-dependent ghosts or veiling glare that changes when the source is blocked.
How it works: Tie flare geometry and intensity to the light source and its occlusion; preserve the chosen optical subtype rather than applying a fixed overlay.
Common mistakes: If the result does not follow this rule, it is not this technique: Tie flare geometry and intensity to the light source and its occlusion; preserve the chosen optical subtype rather than applying a fixed overlay. Do not change multiple variables at once so the effect becomes unreadable.

How to read this page

Lens Flare 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.
