Turning the cafe portrait into a short video
The saved cafe portrait was used as the image reference for a five-second Seedance 2.0 video request.
CharaSync · Sample generated · Case study updated
Input and method
The cafe image from the character example was reused as the input. The prompt requested a small cup lift, a natural smile, subtle hair movement and a locked camera, with no cuts or additional people. The submitted duration was 5 seconds at the 720p setting.
These are real API samples submitted to APIMart using the project request builders. Prompts were sent directly with smart rewriting off. References are public, project-owned fictional assets; outputs were not retouched. They demonstrate sample results, not an end-to-end customer checkout test.
Reference and original outputs
What the result shows
The resulting clip animates the cup movement and expression in one cafe shot. The original reference and playable video are shown below. The saved file is approximately 5.06 seconds long.
Limits and checks
A short, low-motion clip does not demonstrate consistency across long scenes, large camera moves or multiple shots. Playback starts muted; that does not mean the file has no audio track. Check motion, facial details and audio before publishing.

Animate the woman in the reference photo sitting at the outdoor cafe. She gently lifts the white coffee cup a little and smiles naturally. Keep the same face, freckles, auburn bob, tan jacket and black top throughout. Subtle hair movement in a light breeze. Locked camera, one continuous shot, no cuts, no additional people, no text.Test record: task_01M47AWBKQZN49Z30FQYY1BABR
Model outputs vary. Reusing the same input does not guarantee an identical image or video.
