MinimaxHailuo03RegenerateNode - ComfyUI Built-in Node Documentation

This node re-renders a MiniMax H3 768P video output at 2K resolution. It uploads the source video and the exact prompt used to create it, starts a MiniMax H3 regeneration job, and returns the re-rendered 2K video. If the original generation used first or last frames or reference media, attach the same inputs.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The model to use for video regeneration. Selecting this model reveals the prompt, resolution, and reference media settings documented below.	COMBO	Yes	”MiniMax H3”
`prompt`	The exact prompt used to generate the source video. Must not be empty.	STRING	Yes	Text
`resolution`	Resolution to re-render the source video at.	COMBO	Yes	”2K”
`reference_images`	Reference images from the original generation, in the same order. Up to 9 images.	IMAGE	No	0-9 images
`reference_videos`	Reference videos from the original generation, in the same order. Up to 3 videos, 2-15 seconds each, 15 seconds in total.	VIDEO	No	0-3 videos
`reference_audios`	Audio references from the original generation, in the same order. Up to 3 clips, 2-15 seconds each, 15 seconds in total. Cannot be used without a reference image or video.	AUDIO	No	0-3 clips
`video`	The MiniMax H3 768P output video to re-render. Connect the unmodified output of a MiniMax H3 video node (24 FPS, 4-15 seconds). 2K outputs cannot be used.	VIDEO	Yes	24 FPS, 4-15 seconds
`first_frame`	First frame image from the original generation, if one was used.	IMAGE	No	Image
`last_frame`	Last frame image from the original generation, if one was used.	IMAGE	No	Image
`watermark`	Whether to add an AIGC watermark to the video. Default is false.	BOOLEAN	Yes	false / true

Constraints

The source video must be an unmodified MiniMax H3 768P output: width and height divisible by 32, at most 1,032,192 total pixels, 24 FPS, and 107 to 362 frames in steps of 17 (4 to 15 seconds at 24 FPS). 2K outputs cannot be used as the source.
first_frame / last_frame and reference media (reference_images, reference_videos, reference_audios) are mutually exclusive. Use frames for an image-to-video prompt, or reference media for a reference-to-video prompt.
reference_audios requires at least one reference_images or reference_videos input.
reference_images: each image must have an aspect ratio between 0.4 and 2.5 and be at least 256x256 pixels.
reference_videos: each video must be 23.976 to 60 FPS and 2-15 seconds long; total duration cannot exceed 15 seconds.
reference_audios: each clip must be 2-15 seconds long; total duration cannot exceed 15 seconds.
