yeah I was gonna say clone yourself,
but it is much easier if you do the tripod thing get a good long shot of yourself with your expressions interacting with your "other self"
then without shutting off or pausing the camera "do" your otherself" on the otherside(Not litterally, unless your makin's some kinda funky porn flik.)on the other side of the couch.

take the clip , split it, place one on one vid track the second on another,
align as nesc.
use either track motion or pan/crop tho split the screen between the two.
you can repeat the same steps for more of you,.......unless its a loveseat

<extra silly>

If you just want to get silly and do some stunts like maybe kiss yourself or even just talk to yourself instead of going through all the bother of setting up a camera and shooting multiple scenes then joining them together and messing around geting the alignment just right you can play around with the mirror filter.

Just shoot some footage of yourself doing whatever... Now drop the mirror filter on the timeline, select either the reflect left or right option then slowly and carefully move the controller in the work area (that little square) so the reflected image moves just enough away from the original. Because you're working from just a single image it will of course be a perfect mirror image.

Go to this site:

Duals Reloaded

and download the film clip. After viewing it, click on the "Behind the Scenes" link to get all sorts of ideas of what programs are available to produce the effects you just saw. He does exactly what you want to do.

I get green with envy every time I watch this. Remember when you watch it that this guy did this with no budget, no crane (watch the opening shot), and one actor -- himself.

Wow! And one camera operator -- himself. Give the man a medal. I wonder how long it took.

When I first viewed this last summer, I wrote the guy to congratulate him. I think he said, at the time, he was out of work. I gather it took quite a long time. As you've seen, however, the result is absolutely brilliant.

ditto's on the brilliant thing, the behind the scene's page was very infomative too!
All though I must admitt some of the stuff was over my head in terms of the icarus stuff butI got the jist of it.
Even his music score was done by himeself and his wife(she's quite the hotty if you look at his other web pages).
very impressive work, makes me feel like grade school kid popped into a college class but I guess this is how we learn, with people like him and people the great people in this forum willing to pass on their knowlege.

The bit I'd love to know how he did was was the head rebuilding itself.
I know there's some high end particle effects tools that will do that but I'd doubt he had the budget for that.

He claims 3D Studio and After Effects.
