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.


Contents


[edit] Requirements

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

[edit] 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 Layer-base-Lena.png Layer-over-grad.png

Uumtblend-example-blend.png

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