G Posterise is an improvement on the standard posterise type effects, which shift the video tones into discreet steps or bands, because it has the control Softness, which enables you to blend the transition between bands of colours. G Posterise also has the fantastic feature of adding an outline, if desired, on the transitions between the steps of the posterise effect. This can be used to make the video look like a cartoon. Due to the advanced nature of G Posterise, a Show Mapping option draws a graph on screen to show the brightness steps and the softness adjustment for diagnostic purposes.
Control
Settings
Notes
Type
Luma
RGB
Selects whether the posterisation is applied to the luma of the video, or to the RGB channels.
Posterise Steps
1 to 255
The number of individual steps that make up the posterisation effect.
Mix
0 to 100
Controls the blending of the original image with the posterised image. Zero is no posterised and 100% is the full effect.
Offset
-1 to 1
Moves the steps to the left or right in the mapping graph - changes the positioning of the tonal bands.
Brightness
0 to 2
Moves the steps higher or lower, increasing or decreasing the brightness of the effect.
Smoothness
0 to 200
Sets the amount of pre-blur on the effect which make the results smoother - useful for when producing a cartoon effect to reduce the detail.
Softness
0 to 100
Softens the edges of the posterisation steps.
Force Black and White
on
off
Makes the effect black and white.
Add Outline
on
off

Outline Threshold
0 to 255

Outline Opacity
0 to 100
Sets the percentage opacity of the outline.
