MinimaxHailuo03ContextIRNode - ComfyUI Built-in Node Documentation

This node uses MiniMax H3 Context IR to analyze your text description and any attached media, then produces a stronger, structured video prompt. The returned prompt is designed to be connected to the prompt input of a MiniMax H3 video node; if you attach media there, attach the same media in the same order, because the enhanced prompt refers to media by position.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	Model to use for prompt enhancement.	COMBO	Yes	`"MiniMax H3"`
`prompt`	Description of the video you intend to generate. Cannot be empty. (default: `""`)	STRING	Yes	Any text
`duration`	Duration of the video you intend to generate, in seconds (4-15). (default: 5)	INT	Yes	4 to 15
`ratio`	Aspect ratio of the video you intend to generate. `"adaptive"` requires at least one image, video, or audio input. (default: `"adaptive"`)	COMBO	Yes	`"adaptive"` `"16:9"` `"4:3"` `"1:1"` `"3:4"` `"9:16"` `"21:9"`
`reference_images`	Subject or style reference images, referred to in the prompt as “Image 1”..”Image 9” in connection order. Up to 9 images.	IMAGE	No	0 to 9 images
`reference_videos`	Motion or scene reference videos, referred to in the prompt as “Video 1”..”Video 3” in connection order. Up to 3 videos, 2-15 seconds each, 15 seconds in total.	VIDEO	No	0 to 3 videos
`reference_audios`	Audio references, referred to in the prompt as “Audio 1”..”Audio 3” in connection order. Up to 3 clips, 2-15 seconds each, 15 seconds in total. Cannot be used without a reference image or video.	AUDIO	No	0 to 3 clips
`first_frame`	First frame of the video you intend to generate. Cannot be combined with reference media.	IMAGE	No	Single image
`last_frame`	Last frame of the video you intend to generate. Cannot be combined with reference media.	IMAGE	No	Single image

Parameter constraints

The prompt, duration, ratio, reference_images, reference_videos, and reference_audios inputs are part of the model option group.
first_frame and last_frame cannot be combined with any reference media.
reference_audios cannot be used unless at least one reference_image or reference_video is also connected.
When no frames and no reference media are connected, ratio cannot be set to "adaptive".
Reference videos must be approximately 2-15 seconds each, with a total duration of no more than 15 seconds. Their frame rate must be between 23.9 and 60.5 FPS.
Reference audios must be approximately 2-15 seconds each, with a total duration of no more than 15 seconds.
first_frame, last_frame, and every reference image must be at least 256x256 pixels and have an aspect ratio between 0.4 and 2.5.

Outputs

Output Name	Description	Data Type
`STRING`	The enhanced, structured video prompt generated by MiniMax H3 Context IR. It can be connected to the prompt input of a MiniMax H3 video generation node.	STRING
