Random Seed
Sets the random seed so a procedural variation can be reproduced.

Rasterize
Procedural halftone and cell raster generator
Builds a grid of circles, squares, diamonds or custom shapes and can vary their size, position, angle, color and sampling from an image.
This tool belongs to the Krokodove set integrated into DaVinci Resolve 21 and Fusion Studio 21. See the complete Krokodove node list and the comparison with native Fusion tools.
Rasterize
DaVinci Resolve · Fusion
Rasterize is a procedural 2D node for halftone patterns, dot screens, graphic mattes and repeated cell textures.
Overview
What Rasterize does
A virtual grid defines where cells are placed. Each cell can render a circle, square, diamond or custom shape, with jitter controls for position, size and angle.
The selected image channel can influence cell behavior, making Rasterize useful for converting luminance or color information into a stylized dot or shape pattern.
Overlap and supersampling controls determine how cells combine and how clean small repeated geometry remains.
Mental model
Think of Rasterize as a procedural plotter that stamps one shape into every grid cell and can resize or vary those stamps according to image data.
Common uses

Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Channel: Red / Green / Blue / Alpha / Luminance
Chooses the source channel used by Rasterize for the current operation.
Center X / Y
Sets the X/Y coordinates for center.
Size
Sets the overall size.
Angle
Sets the angle of the element.
Aspect
Adjusts the aspect ratio without changing the main scale control.
Grid Size X / Grid Size Y
Sets the horizontal and vertical Grid Size.
Type: Circle / Square / Diamond / Shape
Uses Circle / Square / Diamond / Shape for type.
Jitter Position X / Y
Sets the X/Y coordinates for Jitter Position.
Jitter Position After Sampling
Adds controlled random variation to this property.
Size Black / Size White
Maps dark and bright source values to different cell sizes.
Keep Shape Horizontal
Keeps the Shape element visually horizontal while the surrounding structure is transformed.
Jitter Angle / Jitter Angle Step
Adds controlled random variation to this property.
Lock Black/White Aspect
Adjusts the aspect ratio without changing the main scale control.
Shape Color: Solid / Image / External
Sets Shape Color to Solid / Image / External.
Shape Color / Red / Green / Blue / Alpha
Provides separate controls for the red, green, blue and alpha channels.
Overlap: Maximum / Add / Multiply / Screen
Sets overlap to Maximum / Add / Multiply / Screen.
Super-Sampling: 1x1 / 2x2 / 3x3 / 4x4 / 5x5 / 8x8 / 16x16
Sets Super-Sampling to 1x1 / 2x2 / 3x3 / 4x4 / 5x5 / 8x8 / 16x16.
Practical setup
A reliable workflow
- 1
Choose a grid density.
- 2
Select the cell shape.
- 3
If using an image, choose the driving channel.
- 4
Set black/white size response.
- 5
Add small jitter only after the basic pattern works.
- 6
Increase supersampling if the cells shimmer or alias.

Troubleshooting
Common mistakes

Adding heavy jitter before tuning source response
Rendering small rotated cells without enough sampling
Production notes
Practical tips
Preview at 100 percent pixel scale.
Use Luminance for a predictable halftone start.
A small blur before Rasterize can reduce noisy cell variation.
