Choose the cast and framing
Start with Chandelier party for the reference layout. Portrait remix emphasizes identity; Crowd toast and Celebration crew adjust the reactions. Use landscape 16:9 to keep the guests and chandeliers in view. A second portrait is assigned to the guest beside the lead.
Before you generate
Upload a portrait and choose 480p or 720p. Both options use Seedance 2.5 for a 15-second video. 480p uses 20 purchased credits; the HD rate is shown before generation. A configured video reference guides the host, camera and crowd.
- Use one sharp face in each photo.
- Keep eyes, hair and clothing visible.
- Watch the reference, then review your own result.
