So first off, I'm not sure if I posted this in the right forum so if not, sorry.

I'm looking for a program of some kind that I can combine 4 (if not 2 minimum) streams of video into one file. The only program so far that I've found that does this is avisynth but I can't seem to make it work at all. Does it even work under ubuntu? I've tried numerous guides and how to's but nothing seems to be working.

Basically I just need something that will take a video file, from several different sources (cameras placed around a car) and be able to place them in a grid form into one file. basically in a format like this, where each letter is a different video file:

a b
c d

Thanks!

It's a shame that this cool app isn't getting more 'traction' on linux :

You can use AviSynth in Linux: HOWTO: AviSynth video processing with WINE (http://ubuntuforums.org/showthread.php?t=1333264).

it seems to do very well with avi formats, not so good with high byte rate formats from the start, although the end results are fantastic.

I have done this with blender, cinelerra and kdenlive.
In blender : start with a black image on the lowest track; put the video tracks upon each other above the black image; downsize and relocate them with the transform tool. Alpha over the tracks on the black image.
Cinelerra : I have done this with cinerella but is too long ago to remember how I did this exactly. It was similar to blender.
Kdenlive : look for the PIP (picture in picture) tool.
