A Smile for a Real Shop
Use the small, uneven smile from the shop. A wide identical grin reads as a stock photo, not as your host.
Use the smile that belongs to the shop: small, a little uneven, the kind that shows up when a regular walks in. A wide, identical grin on both sides reads as a stock photo, and it often brings a new face with it. Lock the host first, then ask for that smaller expression. Approve the still before motion, and compare the eyes with the reference. Teeth, if they show, stay a real color. If the host looks real, say the host is AI, and leave the platform label visible. Ask for a slight, uneven smile, compare the eyes with the locked reference, and reject a wide identical grin that brings a new jaw. Keep one speaker. A practical reel is 15–45 seconds. The first 3 seconds show the grocer by the shop window with one corner slightly higher, and they say the shop line. Reject a beaming symmetrical catalog face, a beauty wash, or teeth turned an unreal color. If the face or the voice could be mistaken for a real person, the caption must say it is AI, and the platform label stays visible.
Ask for a small change
Describe a slight smile, not a performance. A closed-mouth lift or a small opening is enough. Words like perfect, beaming, or symmetrical push the face toward a catalog. The eyes should still match the locked still. If the smile replaces the person, reject it. Describe a closed-mouth lift or a small opening, and stop if the smile replaces the person. The first 3 seconds show that small change and say the shop line. Reject the words perfect, beaming, or symmetrical in the description before you generate again.
Uneven is believable
One corner may lift more than the other. That is a person in a room. A mirror-image grin, with identical creases and a full row of even teeth, is the stock look. Skin keeps pores and a real color. The window or the lamp you already use stays the light. Do not add a beauty wash to sell the smile. Allow one corner to lift more than the other, keep pores, and leave the window or lamp you already use. In the first 3 seconds the grin is uneven and the voice says the line. Do not post a mirror-image row of even teeth.
Approve the expression still
The mouth you approve is the mouth that will move. Check it on a phone next to the locked face. Life photos can reuse this host with the same small smile. Label the realistic face as AI, and leave the platform label visible. The shop does not need a bigger expression to be welcoming. Approve the mouth on a phone beside the lock, and reuse that small smile in a life photo of the same host. In the first 3 seconds, viewers see the shop face and hear the line. Throw out the wide grin that also changed the jaw.
A worked example
A grocer stands by the shop window with a small smile, one corner slightly higher, eyes matching the locked reference. The skin is not smoothed. A version with a wide identical grin is rejected because the jaw also changed. The approved still moves, and the caption says the host is AI. Stand at the window, keep the small uneven smile, and reject the version with the identical grin. The first 3 seconds show the grocer's real expression and say the shop line. One speaker, 15–45 seconds. If the face looks real, the caption says the host is AI, and the platform label stays in place.
Before you post
- Keep the smile small and uneven.
- Match the eyes to the locked face.
- Label the realistic host as AI.
Where Scro fits
Scro locks the face so the smile is a change of expression, not a new head. Approve the still before motion. Life photos can reuse that host. Export 9:16, and label the realistic face as AI. Treat the smile as a change of expression on the locked face, then export 9:16. The first 3 seconds show that small smile and say the shop line. Reject a stock-photo grin. If the face or voice could be mistaken for a real person, the caption says it is AI.
Keep the shop smile. Finished samples are on the examples page.
