Best Use Cases
- Fashion Editorials — Create runway-style videos with dramatic fabric movement and cinematic lighting.
- Product Showcases — Animate product images with dynamic camera movements.
- Character Animation — Use multiple reference images for consistent character appearance.
- Storytelling — Combine multiple scene elements into cohesive video narratives.
- Social Media Content — Generate eye-catching videos optimized for different platforms.
Example Prompts
- “Model in a flowing silk gown standing on top of a sand dune, golden sunset light illuminating the fabric, camera circling to capture the dress fluttering dramatically in the wind, high-contrast editorial style”
- “Slow camera push in, hair moving gently in the breeze, warm golden hour lighting”
- “Product rotating smoothly on display, studio lighting creating elegant reflections”
- “Dramatic camera orbit around the subject, fabric flowing in slow motion”
- “Cinematic dolly shot revealing the full scene, atmospheric dust particles in the light”
Multi-Image Tips
| Number of Images | Best Use Case |
|---|---|
| 1 image | Simple animation, single subject |
| 2 images | Before/after, transition effects, dual perspectives |
| 3-4 images | Complex scenes, character consistency, multi-element composition |
Pro Tips for Best Results
- Use multiple images when you need consistency across different elements (character + background + props).
- Include cinematic language: “camera circling”, “dolly shot”, “slow motion”, “dramatic lighting”.
- Describe both subject motion and camera movement for more dynamic results.
- Use negative prompts to avoid “blur”, “distortion”, “static”, “jitter”.
- Match aspect ratio to your platform: 1:1 for Instagram, 16:9 for YouTube, 9:16 for TikTok/Reels.
- Start with 5-second videos to test your concept before generating 10-second versions.
Notes
- If using URLs for images, ensure they are publicly accessible. Preview thumbnails confirm successful loading.
- Processing time scales with duration — 10-second videos take longer.
- Enable Safety Checker for content that will be publicly shared.
- Reference images influence style and composition — choose high-quality sources.
