Swapping Side-by-side 3D Video Images

[MrVideo]

I know how to crop video, but do not have a clue as to how to take a side-by-side 3D video and swap the two video images.

Before you ask why I would want to do that, here is the reason... to be able to look at the video without a 3D TV. I can do the cross-eyed thing where I can cross the eyes with two images and get the 3D to appear. But, TV 3D has the images reversed for doing that trick.

So, as an experiment, I want to swap the two images. Is there an easy way of doing that?

Thanks.

Assuming a 1920x1080 source...

left=crop(0,0,-960,-0)
right=crop(960,0,-0,-0)
stackhorizontal(right,left)

Thanks, much appreciated.

left=crop(0,0,Width/2,-0)
right=crop(Width/2,0,-0,-0)
stackhorizontal(right,left)

A little more general.
