Spherical

This is the default recipe for the Non-Anamorphic Imaging family.

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 equal horizontal and vertical image scale with no anamorphic desqueeze; retain the chosen lens’s own projection and iris behavior rather than forcing flare or aspect-ratio stereotypes.

Spherical: A non-anamorphic optical system uses the same image scale horizontally and vertically and needs no desqueeze. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Use the frontal circle and normal human proportions as geometric references for non-deforming optics.
How it works
Position the disk directly facing the camera and choose the specified 65mm rectilinear lens. Only rotate the dartboard with your hand within the plane of the board, without changing the tilt angle between the board and the camera. Output according to the standard color process and check that the circle has not been distorted due to stretching or pixel aspect ratio.
Common mistakes
Applied double lateral stretch by mistake. Classifying the optical type solely because there are black edges or no flare.

How to read this page

Spherical Lens is one technique in Lenses. 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.
