An image-to-video model: the source image provides the first frame, and the prompt guides the subsequent motion. Creates a short video with optional accompanying audio.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

HappyHorse-1.1-I2V is an Alibaba model that starts a video scene from an existing image. The image becomes the first frame, while text can specify what happens next: a character's movement, changes in the scene and the camera's direction. It is suited to animating an illustration, a product photograph or a prepared visual concept.

A text prompt is optional. Without one, the model infers possible motion from the initial image. When a prompt is supplied, the source image determines the composition and the appearance of objects, while the words guide how the scene develops over time.

#### From the first frame to motion

Alibaba highlights preservation of character appearance, visual consistency, smooth movement and the combination of visuals with audio. Its stated aims also include stable text and textures. These properties describe the model's intended capabilities; they do not mean that every pixel is literally preserved in every generated frame.

This mode uses one initial image. It defines the starting scene rather than providing a set of independent references for a new composition. The ability to specify a separate final frame is not stated for this particular version.

JPEG, JPG, PNG and WEBP are accepted. Each dimension of the input image must be at least 300 pixels; the permitted aspect ratio ranges from 1:2.5 to 2.5:1, and the file size limit is 20 MB. The output video's aspect ratio follows the first frame.

#### Video parameters

The duration is selected as an integer from 3 to 15 seconds. Available resolution levels are 480P, 720P and 1080P; the output format is MP4 at 24 frames per second. Audio can be generated alongside the video.

The prompt may be in any language and contain up to 5000 non-Chinese or 2500 Chinese characters. Any excess is truncated, so important actions and motion details should fit within that limit. The same random seed may produce similar videos, but does not guarantee a frame-by-frame match.

    for x in r.get("data",[]):print(x)
PY_STATUS
```

##### Save all completed assets

GET all completed assets

```bash
set -eu
