Description

This plugin is based on Trevlac's VirtualDub filter ColorLooks and Donald Graft's Colorize (well it works a bit similar). I also added some new stuff. The plugin contains the following filters:

• Colorize provides the ability to convert a video to a monochrome video based on a selectable color. For example, the old-style brown photograph look can be easily obtained, or grayscale clips can be made to look a bit more interesting.

• Posterize just chops down the bit depth of the video. It reduces the number of colors while maintaining a resemblance of the original image characteristics.

• Sepia gives the sepia effect resulting in a monochrome video based on a selectable color.

• Technicolor is a two color process that uses red and cyan as opposed to red, green, blue. So to get this effect, the green and blue level is set to cyan.

Requirements

• [x86]: AviSynth+ or AviSynth 2.5.8 or greater
• Supported color formats: RGB24, RGB32, YUY2, YV12

Syntax and Parameters

Colorize

Colorize (clip, int "color", bool "scale")

clip   =

Input clip, must be YUV.

int  color = 0xa28a65

Color is defined in RGB hexadecimal.

bool  scale = false

scale=false uses the luma of the source clip, and scale=true scales the clip by "luma of source clip / 240" (bright objects stay bright, and dark objects get darker).

Posterize

Posterize (clip, int "pbits")

clip   =

Input clip, must be RGB or YUV.

int  pbits = 8

The pbits setting determines the amount of chopping. pbits=8 means no chopping, and pbits=0 means chopping everything resulting in a black clip.

Sepia

Sepia (clip, int "color", string "mode")

clip   =

Input clip, must be YUV.

string  mode = 0xa28a65

Color is defined in RGB hexadecimal.

bool  scale = "triangular"

Sepia gives the sepia effect resulting in a monochrome video based on a selectable color. It does so by applying color to mid-tones (mode="triangular"), or high-tones (mode="linear").

The luma is copied from the source clip. The default values produce the "true" sepia effect.

Technicolor

Technicolor (clip, string "channels")

clip   =

Input clip, must be RGB or YUV.

string  channels = "R"

The channel option indicates what color should be kept: "G" sets the red and blue levels to magenta, "B" sets the R and G channels to yellow. The default values produce the "true" technicolor effect.

Examples

Colorize (clip, color=0xa28a65, scale=false)

Posterize (clip, pbits=8)

Sepia (clip, color=0xa28a65, mode="triangular") # default values gives the Sepia effect

Technicolor (clip, channel="R") # default values gives technicolor effect
