How do I make before-and-after videos with AI?
Short answer
Anchor the first frame as the "before" state and the last frame as the "after" state, then let the AI generate a satisfying transformation transition between them.
Recommended mode: DirectorScenario: Home renovation, beauty, fitness, and product transformation content for ads and social proof.
Execution Steps
- 1Capture or select a clear "before" image and a polished "after" image from the same angle.
- 2Set the before image as the opening anchor frame and the after image as the closing anchor.
- 3Generate a smooth transformation transition — wipe reveal, gradual morph, or time-lapse style.
- 4Add context text overlays showing the timeline and key changes for viewer clarity.
Prompt Template
Create a 10-second before-and-after transformation video. Use frame A as the starting state and frame B as the final state. Apply a smooth time-lapse morph transition.
Common Failure Points
- Using before and after photos taken from different angles or lighting conditions
- Making the transition too fast for viewers to appreciate the change
- Forgetting to add context about what changed and how long it took
