Dance Everywhere — ComfyUI Node

Make your dancer appear anywhere.

A ComfyUI custom node that composites a masked dancing person video onto any background image. The person's feet are always anchored to the exact position you specify, regardless of scale — enabling realistic placement of a dancer into any scene.

Features

• Foot-anchored placement — set pos_x / pos_y and the person's feet always land there, even as you adjust scale
• Independent scale controls — scale sets the overall size (as a fraction of background height); height_ratio stretches or squishes the person without changing width
• Mask edge feathering — Gaussian blur on the alpha mask for natural blending
• Brightness matching — optionally blend the person's brightness toward the local background for better lighting consistency

Node: 🕺 Dance Video Composite

Category: 🎬 Video/Composite

Inputs

Parameter	Type	Description
person_video	IMAGE	Dancing person video frames (batch)
person_mask	MASK	Alpha mask per frame — connect from a background-removal node (e.g. InspyreNet, rmbg)
background	IMAGE	Background image to composite onto
pos_x	FLOAT 0–1	Horizontal foot position (0 = left, 1 = right)
pos_y	FLOAT 0–1	Vertical foot position (0 = top, 1 = bottom)
scale	FLOAT	Person height as a fraction of background height (0.9 = 90%)
height_ratio	FLOAT	Fine-tune height only: >1 taller, <1 shorter, width unchanged
edge_feather	INT	Mask edge blur radius in pixels
brightness_blend	FLOAT	Blend person brightness toward background (0 = off, 1 = full match)

Outputs

Output	Type	Description
composited_video	IMAGE	Video frames composited onto the background
