comparing 2 same clips from different source

[Lee82]

I have 2 exactly same clips, recorded from different sources (dvdrec & capture card)

I wish to merge both clips onto a single file, having the left half of the screen playing the 1st source, and the right half playing the second.

This is usually done when you see comparisons between xbox and playstation and such stuff.

I actually wish to compare my capture card against my dvd rec for noise settings and such. (and to kill time)

any particular way/software which does this?
Thanks

Exactly how you do it depends on the format of the 2 clips. If AVI, then the script goes something like this:

A=AVISource("C:\Path\To\Video1.avi")
B=AVISource("C:\Path\To\Video2.avi")
StackHorizontal(A,B)

Time to learn some AviSynth.
