MiniMax H3 Image-to-Video
MiniMax H3 Image-to-Video brings a static image to life. Provide a first-frame image — and, optionally, a last frame — plus a prompt describing the motion, and the model generates a smooth, cinematic clip at up to 2K that starts (and optionally ends) exactly on your images.
Why Choose This?
-
Image-driven generation Animate any image with natural, controllable motion.
-
First & last frame control Set the opening frame, and optionally pin the closing frame for a precise transition.
-
High resolution output Generate videos in 2K quality.
-
Flexible aspect ratios Automatically determined by the input image (always adaptive).
-
Selectable duration Produce 4–15s clips.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the desired motion and action |
| image | Yes | First frame of the video (public URL or Base64) |
| end_image | No | Last frame of the video (public URL or Base64) |
| resolution | Yes | Video resolution. Available options: 768P, 2K |
| duration | Yes | Duration of the generated video in seconds. Integer between 4 and 15. Available options: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 |
| ratio | No | Aspect ratio of the generated video. For image-to-video, the aspect ratio is determined by the input image and is always adaptive; passing any other value is ignored. |
| prompt_expansion | No | Enable AI prompt expansion via H3 Context-IR. When true, your prompt is first expanded into a rich, structured description (shot, soundscape, music) before generation, and an additional per-token Context-IR fee applies. Default false: the prompt is used as-is with no extra charge. |
How to Use
- Upload your first-frame image — the video will start from this image.
- (Optional) Upload a last-frame image — the video will end on this image.
- Write your prompt — describe the motion, camera movement, and action.
- Set resolution and duration — balance quality against generation speed.
- Choose an aspect ratio — match your target platform, or use adaptive.
- Run — submit and download your video.
Best Use Cases
- Photo Animation — Bring portraits, landscapes, and product images to life.
- Start/End Transitions — Morph smoothly from one image to another.
- Marketing & Ads — Turn product photos into dynamic promotional videos.
- Storytelling — Animate illustrations and artwork for narratives.
Pro Tips
- Be specific about movement direction, speed, and camera angles.
- When using a last frame, keep the two images' aspect ratios close for a clean transition.
- Use high-quality source images for better video results.
- Describe environmental effects (wind, smoke, dust) for more immersive motion.
Notes
- Both prompt and first-frame image are required.
- The last-frame image is optional; when provided, the clip ends on it.
- Ensure image URLs are publicly accessible.
- Generation is asynchronous — submit, then poll for the finished video.
Related Models
- MiniMax H3 Text-to-Video — Generate video directly from a text prompt.
- MiniMax H3 Reference-to-Video — Keep a subject consistent from a reference image.
