Usage

Merge

Merge(clip clip1, clip clip2 [, float weight ] )

Merges pixels from one videoclip into another.
There is an optional weighting, so a percentage between the two clips can be specified.

clip  clip1 = (required)
The clip that has the pixels merged into (the base clip).
clip  clip2 = (required)
The clip from which the pixel data is taken (the overlay clip).
float  weight = 0.5
Defines how much influence the new clip should have. Range is 0.0–1.0.
  • At 0.0, clip2 has no influence on the output.
  • At 1.0, clip2 replaces clip1 completely.
  • Default is 0.5; output is average of clip1 and clip2.
  • Clips must have the same pixel-type.
  • Audio, FrameRate and FrameCount are taken from the first clip.


MergeChroma

MergeChroma(clip clip1, clip clip2 [, float chromaweight ] ) (depreciated since v2.60)
MergeChroma(clip clip1, clip clip2 [, float weight ] ) (*v2.60 only)

Merges the chroma from one videoclip into another.
There is an optional weighting, so a percentage between the two clips can be specified.

clip  clip1 = (required)
The clip that has the chroma pixels merged into (the base clip).
clip  clip2 = (required)
The clip from which the chroma pixel data is taken (the overlay clip).
float  chromaweight = 1.0
float  weight = 1.0
Defines how much influence the new clip should have. Range is 0.0–1.0.
  • At 0.0, clip2 has no influence on the output.
  • At 1.0, clip2 replaces clip1 chroma completely.
  • Default is 1.0; output chroma taken only from clip2.
  • Alternate name weight added in AviSynth v2.60
  • Clips must have the same pixel-type and be YUV only.
  • Audio, FrameRate and FrameCount are taken from the first clip.


MergeLuma

MergeLuma(clip clip1, clip clip2 [, float lumaweight ] ) (depreciated since v2.60)
MergeLuma(clip clip1, clip clip2 [, float weight ] ) (*v2.60 only)

Merges the luma from one videoclip into another.
There is an optional weighting, so a percentage between the two clips can be specified.

clip  clip1 = (required)
The clip that has the luma pixels merged into (the base clip).
clip  clip2 = (required)
The clip from which the luma pixel data is taken (the overlay clip).
float  lumaweight = 1.0
float  weight = 1.0
Defines how much influence the new clip should have. Range is 0.0–1.0.
  • At 0.0, clip2 has no influence on the output.
  • At 1.0, clip2 replaces clip1 luma completely.
  • Default is 1.0; output luma taken only from clip2.
  • Alternate name weight added in AviSynth v2.60
  • Clips must have the same pixel-type and be YUV only.
  • Audio, FrameRate and FrameCount are taken from the first clip.


Examples

# Blur the Luma channel.
MPEG2Source("main.d2v")
clipY = Blur(1.0)
MergeLuma(clipY )
# Do a spatial smooth on the  chroma channel
# that will be mixed 50/50 with the original image.
MPEG2Source("main.d2v")
clipC = SpatialSoften(2,3) 
MergeChroma(clipC , 0.5)
# Run a temporal smoother and a soft spatial
# smoother on the luma channel, and a more aggressive
# spatial smoother on the chroma channel.
# The original luma channel is then added with the
# smoothed version at 75%. The chroma channel is
# fully replaced with the blurred version.
MPEG2Source("main.d2v")
clipY = TemporalSoften(2,3)
\       .SpatialSoften(3,10,10)
clipC = SpatialSoften(3,40,40)
MergeLuma(clipY, 0.75)
MergeChroma(clipC)
# Average two video sources.
vid1 = AviSource("main.avi")
vid2 = AviSource("main2.avi")
Merge(vid1, vid2)


Changelog

v2.60 Added alias weight for chromaweight and lumaweight.
v2.56 Added Merge.
