What this node does
Pattern synthesizes aCOMFYTV_VIDEO from scratch (no input clip) — you choose a kind and a resolution/frame rate/duration, and it renders a procedural clip on ▶ Run. Each kind uses its own subset of the parameters below.
Output is COMFYTV_VIDEO. To feed native ComfyUI nodes, insert a Bridge — see the bridge guide.
When to use it
- Generate backgrounds, mattes, or transition fills (ramps, radial, noise, plasma).
- Make broadcast test patterns —
colorbars,colorwheel. - Drop in a countdown/count-up leader before a clip.
- Produce a moving noise/turbulence source to drive other effects.
Parameters
kind
Which pattern to generate. Options:ramp, radial, rectangle, noise, perlin, turbulence, cellular, plasma, checkerboard, colorbars, colorwheel, count. Default ramp.
width / height / fps / duration
Output size (16–4096, default 1280 × 720), frame rate (1–120, default 24), and length in seconds (0.5–120.0 step 0.5, default 5.0).
color0 / color1
The two colors used by two-color patterns (ramp/radial/rectangle/checkerboard). Hex strings, defaults#000000 (color0) and #FFFFFF (color1).
p0_x / p0_y and p1_x / p1_y
Start and end points of the ramp gradient, normalized0.0–1.0. Defaults place it as a left-to-right horizontal ramp (p0 = 0.0, 0.5, p1 = 1.0, 0.5). Move them to angle or reposition the gradient.
interp
Ramp gradient easing. Options:linear, smooth, ease_in, ease_out. Default linear.
softness
Edge softness for shape patterns (radial/rectangle),0.0–1.0, default 0.0. Higher feathers the shape edge.
noise_scale / noise_octaves / noise_speed
Controls for the noise-family kinds (noise, perlin, turbulence, cellular, plasma). noise_scale feature size 4–512 (default 64), noise_octaves detail layers 1–8 (default 4), noise_speed animation rate 0.0–10.0 (default 1.0).
seed
Random seed for noise-family patterns,0–99999, default 7.
box_size
Cell/box size in pixels forrectangle and checkerboard, 2–1024, default 64.
bar_intensity
Brightness of thecolorbars pattern, 1.0–100.0 (step 1), default 75.0 (standard 75% bars).
wheel_gamma / wheel_rotate
Forcolorwheel: wheel_gamma 0.0–4.0 (default 0.45) shapes brightness falloff; wheel_rotate -180–180° (step 1, default 0) spins the hue wheel.
count_style / count_direction
For thecount leader: count_style displays seconds or frames (default seconds); count_direction counts down or up (default down).
Outputs
Tips
- Most parameters only apply to their pattern family — e.g.
wheel_gamma/wheel_rotatedo nothing outsidecolorwheel,box_sizeonly affectsrectangle/checkerboard. - Set a long duration and animate
noise_speedto get a moving texture; static kinds (likecolorbars) ignore time. - For a countdown leader, pick
kind = count,count_direction = down, and set duration to the count length.
