Pro Tips for Best Results
- Be specific about motion — describe what moves, how it moves, and the camera behavior.
- Use the Prompt Enhancer to add cinematic details to simple descriptions.
- High-quality source images with clear subjects produce the best animations.
- Describe both subject motion and camera movement for more dynamic results.
- Keep prompts focused — one clear action often works better than multiple complex movements.
- Match aspect ratio to your intended platform: 9:16 for TikTok/Reels, 16:9 for YouTube.
Notes
- If using a URL for the image, ensure it is publicly accessible. A preview thumbnail confirms successful loading.
- Generation time may vary based on current queue load.
- Complex motions or detailed prompts may require iteration to achieve desired results.
