Consistent Character Video Generator

Write the prompt in four parts: subject and reference, one action, environment, and camera. For example: “@Mara stands at a café counter and turns toward a friend with a natural smile. Morning light enters from the left. Medium shot, locked camera, realistic body motion, one continuous take.”

The reference already supplies the face. Repeating a long biography can compete with the visible direction. Add only the fixed clothing or object details that must appear in this shot.

First check facial structure and age. Then inspect hair and clothing edges, hands and object contact, background geometry, and the rhythm of the body movement. Look for flicker, rubbery expression, sliding feet, floating objects, texture changes, or a background person who freezes while the main subject moves.

A clip can be attractive and still fail continuity. Review at normal speed first, then pause only where the problem appears.

Slow movement often reads as generated even when the face is stable. Use concrete timing such as “turns in one natural motion,” “walks at an ordinary pace,” or “background guests continue talking and moving.” Do not ask every element to move. Name the two or three motions that make the scene feel alive.

If the action becomes frantic, simplify the camera before reducing all motion. The subject should move naturally while the shot remains easy to read.

For a multi-shot sequence, create and approve each clip separately. Match wardrobe, light direction, location markers, and the character’s screen position at the cut. A frame near the end of one approved shot can become the reference for the next opening angle.

This keeps failures local. If shot three drifts, you can replace shot three without regenerating the first two or promoting the bad identity into shot four.

A living scene does not require every pixel to move. Name the subject action first, then add one or two background behaviors that support it: curtains shift in a light draft, traffic continues outside, or two guests talk behind the character. The consistent character video generator can then focus on a readable hierarchy instead of inventing motion everywhere.

When a background figure freezes, ask for a small repeating behavior rather than a new story event. When the background warps, reduce camera travel and keep the environment description stable.

Test three clips before committing to a long sequence: a subtle expression change, a natural head turn, and a short full-body action. Together they expose facial, profile, hand, clothing, and gait problems without hiding several failures inside one clip. Use the same reference and similar light so the comparison remains useful.

Record which motion passed, which frame failed, and whether the fix came from a better reference, simpler action, or calmer camera. That record is more valuable than keeping a folder of unnamed retries.
