Creepy Devil Smile — a grin with sharp fangs.
Creepy Devil Smile takes a warm, friendly smile and slowly stretches it too far. The mouth widens, pointed fangs appear and the eyes open wide and stare. The sample opens on a woman with long auburn hair in a white fluffy bunny-ear hat and a cream knit sweater, holding a steaming mug.
The sample
What happens in the Creepy Devil Smile sample.
The sample is a reel of two runs. First, a woman with long auburn hair, a white bunny-ear hat and an off-shoulder cream sweater holds a steaming mug and smiles softly. Her smile grows into a wide grin, then sharp upper and lower fangs appear and her eyes go round. In the second run, a man with dark swept hair in a navy t-shirt smiles in front of a blurred city skyline. His grin stretches from ear to ear, fangs show and his brows lift into a fixed stare.
In both runs the clothes, hair and background never change. Steam keeps rising from the mug, and the city stays soft behind the man. The change is all in the face: the mouth, the teeth and the eyes. The framing also tightens a little as the grin grows, most clearly in the second run. Both runs start from a clear, front-facing smile, so a photo like that gives the grin the same starting point.

Your photo
Photos that suit it.
One-tap effects have one input. The photo you pick is your creative control.
Look into the lens
Both people in the sample face the camera, so the growing grin and fangs stay in full view. A photo taken straight on keeps that view.
Start with a smile
Each run opens on a relaxed smile that then stretches wider. A photo where you already smile mirrors the sample's opening frame.
Chest-up framing
The sample frames both people from the chest or waist up with the face large. Similar framing keeps the teeth and eyes easy to see.

Creepy Devil Smile, answered.
What does the Creepy Devil Smile effect do?
Two short clips: a woman in a bunny-ear hat holding a mug and a man in a navy t-shirt each smile wider until their grins show sharp devil fangs.
Does the creepy devil smile add horns or change the background?
Not in the sample. Both runs keep the same clothes, hair and backdrop: a grey studio wall for the woman and a blurred city for the man. Only the face changes, as the smile widens, fangs appear and the eyes open wide. This effect uses a single photo.
How much does Creepy Devil Smile cost?
2–8 credits per run: 2 credits (~$0.80) at the default length and resolution, more for a longer or sharper clip (2 credits at 5s 720p · 4 credits at 8s 720p · 4 credits at 5s 1080p · 8 credits at 8s 1080p). New verified accounts receive 3 welcome credits once. The welcome bonus covers one supported first run costing 2 credits.

5s or 8s at 720p or 1080p. It follows the shape of your photo. Nothing you export is watermarked, on any plan.
