Need "2x2 video wall" merge utility

[markm]

Hello,

I am looking for a utility to create the effect of a 2x2 video wall. I want to take 4 video files encoded at 320x240 resolution and merge them into a single video file at 640x480 resolution, with the 4 videos being played simultaneously in quadrants (see illustration below).


|---|---|
| 1 | 2 |
|---|---|
| 3 | 4 |
|---|---|


Please respond to this post or e-mail me if you are aware of a utility (or combination of utilities) that can be used to do this!

Cheers,
Mark

You should be able to do this in avisynth

From the avisynth language reference

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

See the avisynth homepage for more info
