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-T2V is an Alibaba model for creating short video scenes from text. The prompt specifies characters, actions, surroundings and visual treatment; this mode does not require a source image. The model produces video and can generate accompanying audio.

The manufacturer highlights understanding of a scene's meaning, cinematic staging and expressive movement. Text can define the atmosphere, a character's actions, object behavior and physical dynamics. This makes it possible to build a scene around what should happen, then guide it through lighting, viewpoint and camera movement.

#### Staging with words

A prompt is required and may be in any language. It can contain up to 5000 non-Chinese or 2500 Chinese characters; any excess is truncated. The action, surroundings and important visual details need to be described within that limit. This approach leaves the model room to create a new scene rather than supplying it with a finished first frame.

In this mode, text is the main controlling input. The specific appearance of a character or object can be described in words; supplying separate images to establish that appearance belongs to another mode in the family. The result depends on the entire prompt, so the same random seed can help produce similar variations without guaranteeing an exact repeat.

#### Video and accompanying audio

For HappyHorse-1.1, video duration is selected as an integer from 3 to 15 seconds. Resolution levels of 480P, 720P and 1080P are supported. The finished file is MP4 at 24 frames per second. The model can generate audio alongside the visuals, connecting the soundtrack to what happens in the scene.

The frame shape can be specified in advance. Available ratios are 16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4, 9:21 and 21:9, ranging from a wide cinematic frame to an elongated portrait video. Resolution, format and duration determine the dimensions of the result; text defines its content and movement.

This variant is intended to create a new scene from a verbal concept. It is suited to a short episode, a visual idea or an atmospheric video whose staging needs to be expressed in text.
