☀️ Why it stands out
- Context-aware audio generation Automatically generates synchronized audio that matches the visual content — ambient sounds, dialogue, music, and sound effects.
- Reference image support (R2V) Provide 1-3 reference images to maintain subject consistency across the generated video. Ideal for brand assets, character-driven content, and product videos.
- Frame interpolation Supply a start image and an end image (last frame) to create smooth transitions between two scenes.
- Image-to-video Start from any image to animate it into a video while preserving the original composition and style.
- Up to 1080p resolution Generate videos in 720p or 1080p with 16:9 or 9:16 aspect ratios.
- Flexible duration Choose 4, 6, or 8 second clips depending on your needs.
- Negative prompts Explicitly exclude unwanted elements from the generation for more precise control.

🔥 Pricing
| Config | RouteAny | Fal.ai | Replicate |
|---|---|---|---|
| 8s 720p no audio | $0.40 | $0.80 | $0.80 |

| 8s 1080p with audio | $1.20 | $1.80 | $1.80 |
Shorter durations (4s, 6s) are proportionally cheaper.
💡 Best Use Cases
- Short-form social content — Generate TikTok, Reels, and Shorts with synchronized audio in 9:16 format.
- Product demos & ads — Use reference images to keep brand consistency across video clips.
- Cinematic B-roll — Create atmospheric establishing shots with natural sound design.
- Storyboarding & previz — Quickly visualize scenes before committing to production.
- Scene transitions — Use frame interpolation to create smooth transitions between two keyframes.
📝 Notes
- Reference images (R2V) only work with 16:9 aspect ratio and 8-second duration. Last frame is ignored when reference images are provided.
- Ideal input images are 1280x720 (16:9) or 720x1280 (9:16).
- Audio generation adds processing time but produces context-aware sound that matches the visual content.
- Please ensure your prompts comply with Google's Safety Guidelines.
