StackHorizontal

From Avisynth

StackHorizontal(clip1 clip, clip2 clip [, ...])
StackVertical(clip1 clip, clip2 clip [, ...])

StackHorizontal takes two or more video clips and displays them together in left-to-right order. The heights of the images and their color formats must be the same. Most other information (sound track, frame rate, etc) is taken from the first clip - see here for the resulting clip properties. StackVertical does the same, except from top to bottom.

Examples:

# compare frames with and without noise reduction:
StackVertical(last, last.!SpatialSoften(2, 3, 6))

# show clips in variables a,b,c,d in a box like this:
# a b
# c d
StackVertical(!StackHorizontal(a, b), !StackHorizontal(c, d))
