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 (0d-255d).
  • 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.

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)
