Frame-to-Frame Workflow: From First Frame to Final Scene

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: 5 or 10 seconds

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
