Blender always crashes with long shots.

When i try to do some stuff in the compositor where i have many frames, not even big ones, 640 - 480. blender crashes.

So , i want to do a matchmoving composite, and i open my shot in a sequence of png’s, and i also put it in the 3D view to see it as background image and it always crashes.

Does blender dont support this jobs ?

I have 2ram memory and a core2duo processor.

How does your blender behaves with this kind of tasks?

Can’t you see how much memory blender uses of the 2 gigs when doing that. You can see that with task manager if you’re using windows.
