## StackHorizontal / StackVertical

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

`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.

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

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