PixverseV6ExtendVideoNode - ComfyUI Built-in Node Documentation

This node continues an existing video using the PixVerse V6 model, optionally generating a native audio track alongside the continuation. The source video must be shorter than 40 seconds and no larger than 1920 pixels on either side. The output keeps the source video’s resolution, so the quality setting controls how well the continuation is rendered rather than the frame size.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`video`	Video to continue.	VIDEO	Yes	Under 40 seconds; at most 1920 pixels width and height
`model`	Model and generation settings.	DYNAMIC_COMBO	Yes	”PixVerse V6”

PixVerse V6 Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Prompt describing how the video should continue. (default: empty)	STRING	Yes	1–5000 characters
`quality`	Render quality of the generated continuation: 1080p looks markedly better than 540p or 360p. It never resizes - the output keeps the source video’s resolution. (default: “720p”)	COMBO	Yes	”360p" "540p" "720p" "1080p”
`duration_seconds`	Length of the generated video in seconds. (default: 5)	INT	Yes	1–15
`generate_audio`	Generate a native audio track together with the video. (default: true)	BOOLEAN	Yes	true / false
`seed`	Seed for video generation. PixVerse records it but does not reproduce a run from it. (default: 42)	INT	Yes	0–2147483647
`negative_prompt`	An optional text description of undesired elements in the video. (default: empty)	STRING	No	Up to 2048 characters
`style`	An optional visual style applied to the whole video. (default: “none”)	COMBO	No	Multiple options available; “none” is the default

Note: The source video must be shorter than 40 seconds and at most 1920 pixels on both width and height; longer or larger videos are rejected. The generated output keeps the source video’s resolution, so quality changes rendering fidelity, not the output frame size. The prompt is required and must contain between 1 and 5000 characters after trimming whitespace. The negative_prompt, when provided, is limited to 2048 characters. The seed is recorded by PixVerse but cannot be used to reproduce the same run.

Outputs

Output Name	Description	Data Type
`video`	The generated continuation video, at the same resolution as the source video.	VIDEO
