Frame-to-Frame Workflow: From First Frame to Final Scene
Use first and tail frames to generate smooth AI video transitions with stable subject identity.
Why Frame-to-Frame
Frame-to-Frame is best when you already know the start and end visual state and need an interpolated clip between them.
Input Requirements
- First frame image URL
- Tail frame image URL
- Prompt
- Optional negative prompt
- Duration:
5or10seconds
Generation Behavior
The API validates required inputs and duration. After task creation, status is tracked through polling and webhook updates.
Reliability Notes
- Task records are saved in
video_generation - Output URLs can be archived to first-party storage
- Repeated webhook callbacks are handled idempotently
Prompting Tips
- Mention continuity requirements explicitly
- Use a negative prompt to suppress artifacts
- Keep style instructions consistent with both keyframes
When to Use It
- Product reveal transitions
- Character transformation sequences
- Day-to-night or scene-mood shifts
