[Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/HappyHorseTextToVideoApi/en.md) ## Overview Generates a video based on a text prompt using the HappyHorse model. This node sends your prompt and settings to the HappyHorse API, waits for the video to be generated, and then downloads the result. ## Inputs | Parameter | Data Type | Required | Range | Description | | ----------- | --------- | -------- | --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `model` | DICT | Yes | See Description | A dictionary containing the model selection and its associated parameters. The model must be `"happyhorse-1.0-t2v"`. This dictionary includes the following sub-parameters:

**`prompt`** (STRING): The text description of the video you want to generate. Supports English and Chinese. (default: "").
**`resolution`** (COMBO): The resolution of the output video. Options: `"720P"`
`"1080P"`.
**`ratio`** (COMBO): The aspect ratio of the output video. Options: `"16:9"`
