What this node does

Paint Strokes lets you draw brush strokes on the node’s video preview; on ▶ Run it applies them to the clip over a chosen time window. Each stroke has a brush mode — clone (paint in offset pixels to cover something), blur (soften an area), or color (paint a flat color) — plus radius and hardness. An optional second video can be used as the reveal source that clone/reveal strokes paint from. Video in/out is COMFYTV_VIDEO. A second optional COMFYTV_VIDEO, reveal_video, supplies pixels for reveal-style painting. Bridge to native ComfyUI nodes via ComfyTV/Bridge — see https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md.

​
The on-node editor

The card overlays a paint canvas on the video:
  • Pick a brush mode (clone / blur / color) and set radius, hardness.
  • Clone mode uses an offset (dx, dy); blur uses sigma; color uses a color swatch.
  • Press and drag to paint a stroke; pen pressure is captured per point when available.
  • Undo removes the last stroke; Clear wipes them all.
You must draw at least one stroke before running, or the node raises “draw a stroke on the node first.”

​
Parameters

​
strokes

The painted strokes, stored as JSON — each entry has mode, points:[{x,y,p}], radius, hardness, and mode-specific fields (dx,dy for clone, sigma for blur, color for color), plus optional life_start/life_end. Written by the on-node editor as you paint. Default empty.

​
t_start / t_end

The time window (seconds) the strokes apply over. t_start 0–3600 default 0; t_end default -1 (end of clip), range -1–3600, step 0.05.

​
video (input)

The clip to paint on.

​
reveal_video (input, optional)

A second clip used as the source for reveal/clone painting. Leave empty for in-clip clone.

Tips

  • Strokes are drawn at fixed positions; they do not track motion. For a moving fix, keep the window short or split the shot.
  • Clone with a small dx/dy offset to cover a spot with nearby clean pixels; use reveal_video when the clean pixels come from a separate plate.
  • Higher hardness gives a crisper brush edge; lower blends more with the surroundings.
  • Spot Remover — box-based removal of a static spot/wire
  • Face Blur — auto-detects and obscures faces
  • Roto Mask — draw a matte instead of painting pixels
