Merge

Merge

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

Merge (blend) one video clip into another.

clip  clip1 = (required)

clip  clip2 = (required)

Base clip, overlay clip.

float  weight = 0.5

Strength of effect. 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 be in the same colorspace.
• Audio, FrameRate and FrameCount are taken from the first clip.

MergeChroma

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

Merge chroma from one video clip into another.

clip  clip1 = (required)

clip  clip2 = (required)

Base clip, chroma overlay clip.

float  chromaweight = 1.0

float  weight = 1.0

Strength of effect. 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 be in the same colorspace and YUV only.
• Audio, FrameRate and FrameCount are taken from the first clip.

MergeLuma

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

Merge luma from one video clip into another.

clip  clip1 = (required)

clip  clip2 = (required)

Base clip, luma overlay clip.

float  lumaweight = 1.0

float  weight = 1.0

Strength of effect. 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 be in the same colorspace and 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.
