How to crop to extract a portion of a movie

I have a series of images at a resolution of 1024x768. Inside each image is another image that is 640x480.

I would like to be able to crop out the 640x480 images and creates a movie strip from them.

I tried bringing all the images into Blender at 1024x768 and render that as a single movie.
I then tried to bring that movie in at 640x480. However when I try to crop things to just include the 640x480 images, Blender scales and distorts things.

How can I get Blender to extract the 640x480 movie.

By doing a quick search, under the 2.4 manual it says something about "Strip properties". Not sure if it's changed much under 2.6x. On the panel images, looks like you can crop under the input values.

Also it should be fairly easy to do something like this with VirtualDub if you're on a Windows OS. (In case Blender doesn't cooperate for some reason.)

Not sure how much that helps. (Still fairly new to Blender myself.) But there ya go.

I found a way to crop the images before bringing them into Blender. I think that is going to work for me.
