# minimax-h3-spicy/image-to-video

> MiniMax H3 generates 2K video clips up to 15 seconds with native stereo audio from a source image. Supports first-frame and last-frame image-to-video modes. Animate still images into smooth, cinematic video with synchronized audio.

- **Provider:** AirCube
- **Category:** image-to-video
- **Price:** $0.7000 per run

## Key Features

- Animate still images into 2K video with native stereo audio.
- First-frame and optional last-frame mode — use images as start and end keyframes.
- Up to 15-second video clips from source images.
- Automatic aspect ratio detection from input image dimensions.
- High-fidelity motion generation that respects the original image content and composition.
- Built-in audio synthesis — generates synchronized sound effects and ambient audio.

## Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| `prompt` | Yes | Text description of the motion and audio to generate. |
| `image` | Yes | Source image URL to animate (first frame). |
| `last_frame_image` | No | Optional last frame image URL — the model interpolates between first and last frames. |
| `duration` | No | Video length in seconds: 4-15 (default: 5). |
| `resolution` | No | Output resolution: 480p, 512p, 720p (768P), 1080p (2K) (default: 720p). |

## How to Use

1. Upload a high-quality source image that you want to animate.
2. Optionally upload a last-frame image for keyframe interpolation.
3. Write a prompt describing the desired motion, camera movement, and audio.
4. Select duration and resolution — the aspect ratio is automatically determined from your image.

## Best Use Cases

- Bringing product photos to life with motion and ambient sound.
- Creating social media video content from static photography.
- Animating artwork, illustrations, and concept art.
- Generating video transitions between two keyframe images.

## Pro Tips

- The aspect ratio is automatically derived from your input image — no need to set it manually.
- Describe both visual motion AND audio in your prompt for best results.
- Use high-resolution input images (up to 5,760px per side) for best quality.
- Supported formats: JPG, JPEG, PNG, WEBP, HEIC, HEIF (max 30 MB).
- Use the optional last_frame_image for controlled start-to-end transitions.

## Notes

- Image-to-video and reference-to-video modes are mutually exclusive.
- Input images must have an aspect ratio between 2:5 and 5:2.

## FAQ

**Q: What image formats are supported?**

JPG, JPEG, PNG, WEBP, HEIC, and HEIF — max 30 MB per image, dimensions between 256 and 5,760 pixels per side.

**Q: Can I provide both first and last frames?**

Yes — use the image parameter for the first frame and last_frame_image for the last frame. The model will interpolate between them.

**Q: Does the output include audio?**

Yes — H3 generates native stereo audio synchronized with the video content.
