ComfyCloudMiniMaxH3TextToVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

Runs the MiniMax H3 text-to-video workflow on a Comfy Cloud GPU and returns a video with a matching soundtrack. Picture and audio come out of the same pass instead of being dubbed on afterwards. This is a beta node and is billed by GPU second.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	The text description of the video, including the sounds the shot should carry. Leading and trailing whitespace is removed before submission.	STRING	Yes	1 to 4096 characters
`seed`	Random seed that controls the generated result (default: 42).	INT	Yes	0 to 18446744073709551615
`aspect_ratio`	Aspect ratio of the generated video (default: `"16:9"`).	COMBO	Yes	`"1:1"` `"3:4"` `"2:3"` `"3:2"` `"4:3"` `"16:9"` `"9:16"` `"21:9"`
`resolution`	Frame size budget (default: `"480p"`). 720p costs roughly twice the GPU-seconds of 480p.	COMBO	Yes	`"480p"` `"720p"`
`duration_seconds`	Length in seconds (default: 5). The pipeline quantises to 17-frame steps at 24 fps, so the clip lands within about two thirds of a second of this value.	INT	Yes	5 to 15

Outputs

Output Name	Description	Data Type
