ViduMultiFrameVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

This node generates a video by creating transitions between multiple keyframes. It starts from an initial image and animates through a sequence of user-defined end images and prompts, producing a single video file as output.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`model`	The Vidu model to use for video generation.	COMBO	Yes	”viduq2-pro" "viduq2-turbo”
`start_image`	The starting frame image. Aspect ratio must be between 1:4 and 4:1.	IMAGE	Yes	Aspect ratio 1:4 to 4:1
`seed`	A seed value for random number generation to ensure reproducible results (default: 1).	INT	Yes	0 to 2147483647
`resolution`	The resolution of the output video.	COMBO	Yes	”720p" "1080p”
`frames`	Number of keyframe transitions (2-9). Selecting a value dynamically reveals the required inputs for each frame.	DYNAMIC_COMBO	Yes	”2" "3" "4" "5" "6" "7" "8" "9”

Frame Inputs (shared by all frame count options)

When frames is set to a number, the following three inputs are shown for each frame i from 1 to that number. For example, choosing “3” adds prompt1 / end_image1 / duration1, prompt2 / end_image2 / duration2, and prompt3 / end_image3 / duration3.

Parameter	Description	Data Type	Required	Range
`prompt{i}`	Text prompt for frame {i} transition. Multiline text field. Maximum 2000 characters.	STRING	Yes	Up to 2000 characters
`end_image{i}`	End frame image for segment {i}. Aspect ratio must be between 1:4 and 4:1.	IMAGE	Yes	Aspect ratio 1:4 to 4:1
`duration{i}`	Duration for segment {i} in seconds (default: 4).	INT	Yes	2 to 7

Notes:

All inputs are required. seed has a default value but is still a required input.
start_image and every end_image{i} must have an aspect ratio between 1:4 and 4:1.
Every prompt{i} has a maximum length of 2000 characters.
Every duration{i} must be between 2 and 7 seconds.

Outputs

Output Name	Description	Data Type
`output`	The generated video file containing all the animated transitions.	VIDEO
