Category Layering
Requirements *YV12, RGB24, RGB32
License
Discussion Doom9

Blend (Overlay, Layer) two clips using MaskTools. Wide selection of blend modes. YV12 sources are supported, but the result may be unexpected. Use RGB sources for correct blending. Unlike Overlay and Layer, there is no support for Masking.


Requirements

  • AviSynth 2.6 or later
  • Supported color formats: YV12, RGB24, RGB32
  • Color format of the two clips must match.


Required Plugins


Syntax and Parameters

uu_mt_blend(clip C, clip D, float "opacity", string "mode", int "cmode", bool "showargs")


clip  C =
Base clip.


clip  D =
Overlay clip.


float  opacity = 1.0
identical to the Overlay opacity parameter:
0.0 = no effect; the base clip appears normally.
1.0 = maximum effect.


string  mode = "blend"
Mode Example Description
 Normal Blending Modes
blend

This is the default mode – ordinary transparent blending.
 Darkening Modes
darken Use overlay only if the overlay is darker than the base image.
multiply Darkens the image in proportion to Overlay lightness.
cburn aka color burn. Darker than Multiply.
lburn aka linear burn (darken)
subtract aka Overlay mode="subtract"
 Lightening Modes
lighten Use overlay only if the overlay is lighter than the base image.
screen Lightens more strongly.
cdodge aka color dodge. Brighter than the Screen blend mode.
ldodge aka linear dodge or add (lighten)
divide Lightens the image in inverse proportion to Overlay lightness.
 Contrast Modes
overlay Uses a combination of the Screen blend mode on the lighter pixels, and the Multiply blend mode on the darker pixels.
softlight Uses a combination of the Screen blend mode on the lighter pixels, and the Multiply blend mode on the darker pixels.
hardlight Uses a combination of the Linear Dodge blend mode on the lighter pixels, and the Linear Burn blend mode on the darker pixels.
pinlight Uses a combination of the Lighten blend mode on the lighter pixels, and the Darken blend mode on the darker pixels.
vivid aka vivid light
linear aka linear light. Uses a combination of the Linear Dodge blend mode on the lighter pixels, and the Linear Burn blend mode on the darker pixels.
gextract aka Gimp GrainExtract, Subtract (darken)
gmerge aka Gimp Grain Merge.
 Inversion Modes
exclude Blending with white inverts the base color values; blending with black produces no change.
 Cancellation Modes
absdiff Absolute difference: identical pixels are black, non-identical pixels are brighter in proportion to the difference.
absdiff4 Absolute difference, exaggerated 400% to view small differences clearly.
absdiff16 Absolute difference, exaggerated 1600% to view small differences clearly.


int  cmode = 2
identical to the MaskTools U and V parameters:
  • -255..0 : all the pixels of the plane will be set to -x (-128 = gray)
  • 1 : the plane will not be processed. Content will be invalid.
  • 2 : the plane of the first input clip will be copied (the default)
  • 3 : the plane will be processed with the processing the filter is designed to do.
  • 4 : the plane of the second input clip will be copied.
(does not apply if sources are RGB)


bool  showargs = false
If true, shows the MaskTools expression being used. For Masktools geeks.
