Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image
Mask	Mask of the sweep

Vertical Scan¶

Adds a vsync scanline, similar to the effect when shooting a computer screen with a number of frames per second lower than the screen’s refresh rate.

Inputs	Description
Scale	Height of vertical scan
Position	Position (in Y)
Opacity	Opacity of scan
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image
Mask	Mask of the scan

Simple Film Grain¶

Simulates film grain.

Inputs	Description
Image	Original image
Coarse Grain	Intensity of larger, base grain
Fine Grain	Intensity of smaller, detail grain
Scale	Scale of the grain

Offset	Offset position. Useful to animate.
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image

Vignette¶

Adds a vignette effect.

Inputs	Description
Image	Original image
Blur	Soften vignette edges
Center X	X position of the vignette
Center Y	Y position of the vignette
Width	Width of the effect
Height	Height of the effect
Opacity	Vignette opacity
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image

Vignette Blur¶

Applies a vignette effect, but instead of darkening around the image it blurs. It can be used to suggest a fantasy environment, a smaller scale or a special kind of vision. It can also be used for a tilt shift effect by plugging in a mask.

Inputs	Description
Image	Original image
Strength	Opacity of the blur effect
Image Blur	Blur of the original image
Vignette Blur	Blur of the vignette mask
Width	Width of the vignette
Height	Height of the vignette

Outputs	Description
Image	The resulting image

CRT Scanlines¶

Simulates scanlines like those found in old CRT monitors/tube TVs

Inputs	Description
Image	Original image
Opacity	Opacity of the scanlines
Color	Color of the scanlines

Outputs	Description
Image	The resulting image

Posterize¶

Converts continuous gradation of tone into several regions of fewer tones.

Inputs	Description
Image	Original image
Levels	Regions to separate gradation into
Alpha Level	Levels for the alpha channel
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image

Infrared¶

Simulates infrared vision. It uses the color data in the image to figure out infrared radiation. The results are not hyper realistic since it’s based on the color data but they are fairly accurate.

For more information on Infrared vision, check Wikipedia

Inputs	Description
Image	Original image
Hue Shift	How much of the hue to shift in the image
Color Wash	Adds a tint of color
Colorization	Adds color from the original image
Noise	Add extra noise for realism
Gamma	Final gamma adjustment
Gloom	Gloom effect (adds blur)
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image

Thermal Vision¶

Simulates Thermal Imagining, sometimes called “Predator vision” too. Thermal vision allows too see the differences in Infrared radiation. Since hotter objects emit more infrared than cooler, it’s possible to see the variation in temperature this way. This node will push reds to show more temperature than blues and greens.

You can read more about Thermal Vision on Wikipedia

Inputs	Description

Noise	Add noise to the final image (more realistic)
Mask	Mask out areas of the effect

Outputs	Description
Image	The resulting image
