MergeRGB

MergeARGB(clip clipA, clip clipR, clip clipG, clip clipB)
MergeRGB(clip clipR, clip clipG, clip clipB [, string pixel_type ] )

Merge the alpha (transparency) and color channels from the source video clips into the output video clip.

clip  clipA =

Provides the alpha data to merge into the output clip.

• For a YUV format clip, the data is taken from the Y (luma) channel.
• For an RGB32 format clip, the data is taken from the A (alpha) channel.
• RGB24 clips cannot be used.

clip  clipR =

clip  clipG =

clip  clipB =

Provide the R, G and B data respectively to merge into the output clip. Input clips may be a mixture of all formats.

• For YUV format clips, the data is taken from the Y (luma) channel. Source data should be full range (0_d-255_d).
• For RGB format clips, the data is taken from the respective source channel: R to R, G to G and B to B.

string  pixel_type = "RGB32"

Specifies the output pixel format. Valid values are "RGB32", "RGB24".

AVS+ also supports "RGB48", "RGB64"

The unused channels of the input clips are ignored. Audio, FrameRate and FrameCount are taken from the first clip.

[edit] Examples

# Blur the Green channel only.
MPEG2Source("main.d2v")
ConvertToRGB24()
MergeRGB(Last, Blur(0.5), Last)

# Swap the red and blue channels;
# load the alpha from a second source.
vid1 = AviSource("main.avi")
vid2 = AviSource("alpha.avi")
MergeARGB(
\    vid2, 
\    vid1.ShowBlue("YV12"), 
\    vid1, 
\    vid1.ShowRed("YV12")
\ )
AudioDub(vid1)
