Trying to join two 4:3 videos into side-by-side widescreen version

[cayblood]

I'm trying to figure out how to take two 4:3 videos and convert them into a single widescreen video with a custom aspect ratio that places one of them on the left side and the other on the right side. I'd like to do this for a presentation, so that a video of the presenter can be show on one side and a video of the presenter's slides can be shown on the other side. Ideally, I'd like to be able to script the conversion process, so that once I had clipped off any timing differences at the beginning, I could just feed both videos into a script and get a single video as output without having to do anything manually inside a video editor.

Is this possible? I would really appreciate any tips or advice anyone can give me.

Thanks,
Carl

One other thing, I'd also like to be able to take this custom aspect ratio widescreen and convert it to a flash movie so that it can easily be viewed online. Are there any good flash players out there that support odd aspect ratios like this? It'd be nice if they didn't just letterbox like google video and youtube do.

Putting two videos side by side is very simple in avisynth using the stack statement. There are a few samples here
