HappyHorseTextToVideoApi - ComfyUI Built-in Node Documentation - ComfyUI

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.

`seed`	Seed to use for generation. Using the same seed with the same inputs will produce the same result. (default: 0).	INT	Yes	0 to 2147483647
`watermark`	Whether to add an AI-generated watermark to the result. (default: False).	BOOLEAN	Yes	True / False

happyhorse-1.1-t2v Inputs

`prompt`	Prompt describing the elements and visual features. Supports English and Chinese. (default: "").	STRING	Yes	-
`resolution`	The resolution of the output video.	COMBO	Yes	”720P" "1080P”
`ratio`	The aspect ratio of the output video.	COMBO	Yes	”16:9" "9:16" "1:1" "4:3" "3:4" "21:9" "9:21" "5:4" "4:5”
`duration`	The length of the video in seconds. (default: 5, min: 3, max: 15, step: 1).	INT	Yes	3 to 15

happyhorse-1.0-t2v Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Prompt describing the elements and visual features. Supports English and Chinese. (default: "").	STRING	Yes	-
