The five-second rule

Start with five seconds. A short clip is cheaper to test, easier to review, and less likely to drift into a different face or scene. A single small motion is enough to make a portrait feel alive.

Good first motions: a blink, a slow head turn, hair moving in a breeze, fog drifting, a light sweep, or a slow push-in. Avoid walking, dancing, costume changes, and scene cuts until the short clip is consistently good.

A video prompt that protects identity

The prompt should repeat the visual invariants: face, costume, hairstyle, body proportions, lighting, and number of people. It should describe the motion and the camera separately. It should also forbid identity changes, extra characters, and scene cuts.

The Midnight Braids video prompt is a good template: keep the reference image, turn the head slowly toward the camera, move loose hair and the clothing edge, drift fog through the garden, push in slowly, and maintain stable anatomy and lighting.

What to check before generating

Open the still at full size. Check the eyes, hands, jewelry, hairline, and the boundary between the subject and the background. If the still has a visible error, the video will make it more obvious.

Use a portrait with a clear face and a simple composition. A busy scene gives the model more opportunities to introduce motion artifacts. A centered subject with a stable background is easier to animate.

• Face sharp and fully visible.
• No extra people or ambiguous limbs.
• Costume details that should not change are clear.
• Background simple enough to animate without warping.

Cost, credits, and failure handling

Video jobs use more provider capacity than image edits, so they cost more credits. The workspace shows the cost before you submit. A failed job releases the reservation instead of silently charging you.

If a clip fails, do not keep resubmitting the same prompt. Check the source image and simplify the motion. A shorter, quieter prompt is often more reliable than a long list of effects.

Where the clip works best

A five-second portrait clip works well as a social post, a story, a loop, or a hero background. It is not a replacement for a filmed costume reveal. Keep the clip clearly labeled as AI-generated and do not present it as documentary footage.

For a couple or pet, use the same principle: one subject or one pair, one small motion, one camera move. The more identities and actions you add, the more likely the model is to lose one of them.
