The `inference.minimax.h3.chili.img2vid.v0` job animates an uploaded image
into a 24 fps video with synchronized stereo audio.

Upload the starting image as a job input and set `first_frame` to its
filename. You can also upload an ending image and name it in `last_frame`
to guide the closing frame. If these fields are omitted, the first upload
is the starting frame and the second upload, when present, is the ending
frame.

```json
{
    "type": "inference.minimax.h3.chili.img2vid.v0",
    "config": {
        "prompt": "the scene comes to life, camera slowly pushing in",
        "first_frame": "input.jpg",
        "duration": 8
    }
}
```

`prompt` is required and must contain 3–7000 characters. Describe both the
visual scene and the sounds you want to hear.

`duration` accepts whole seconds from 4 to 15 and defaults to 6. The actual
video may be slightly longer than requested: 4 seconds produces about
4.46 seconds, and 15 seconds produces about 15.08 seconds.

`resolution` supports only `768P`, which is also the default. Exact output
dimensions depend on the aspect ratio. `seed` accepts an integer from 0 to
2147483647 for reproducible generation; omit it to use a random seed.

The output aspect ratio follows the starting image. `aspect_ratio` accepts
only `adaptive`, which is also the default.
