Combining two clips into one (side-by-side not end-to-end)

How do I take two video clips that were shot at the same time and merge them so they play simultaneously in a single video?

I have video from a scene that was shot with two cameras at the same time from about 50 yards apart. I'm trying to merge them so that in a single video file you can see both of them at the same time.

I realize I'll have to reduce the size of the images to get them to both fit and have no problem with that. I just need to know what software (either on a Mac or a Windows machine) will let me do this.

I'm hoping this can be done with consumer level software. Something like QuickTimePro, perhaps. (Looking at the overview of QuickTimePro, I don't see anything that indicates that it can do this, but it may very well be capable.)

Anything out there that will let me combine the clips without costing an arm and a leg?

I use Adobe Premiere Elements for this. Any decent video editing software should be able to do it.

I use a shell script, mencoder and netpbm to do this for free. Mail me if you need a copy of the script, it's very short.

Apparently you can do this with Windows Movie Maker and the Split Video package available on this site. It seems to be using some kind of transition hack, but people on the forums reported it working.

You can use a similar set of hacks (free/cheap) with iMovie, if you have that on your Mac.

If you have $100 to spend on this and want some more features, your best bet is probably to pick up a copy of Final Cut Express. If it is just for one movie, you might be able to do it with the trial version.

(I should also note that I've looked around Mac's "iMovie" and don't see it there. That said, I don't really know what I'm doing, so it's possible it has the capability and I just don't know how to get to it. The searching I've done has all lead to tutorials on how to combine clips end to end.)

Out of curiosity, are you making a 3D stereogram movie?

You can do this for free in a couple of lines using Avisynth:

TimeTravelSpeed: No, I wasn't doing a stereogram movie, but I'm intrigued with the idea now that you mention it and I've thought about it. I'll have to give that a try too.

turkeyphant: AviSynth did the trick (with some help from VirtualDub which I needed to read the AviSynth .avs files and create the final output). Thank you!

I'm still messing around with some of the options and am probably going to go more with a picture-in-picture format. In the first iteration, AviSynth did the side-by-side just fine. It's just that after watching it, it didn't quite line up with what I had in my minds eye.

To give credit where it's due, I found sample AviSynth scripts to use as a starting point for creating the picture-in-picture version here.

I'll post a link to the video when I've got it posted.
