Cropping problem 800x600 -> 640x480

Hi, hope someone can help me with this one.
I need to crop a 800x600 video to 640x480. The cropping that I want is the simplest one: just keep the first 640x480 pixels of the original.
The problem I find is that when I set up the project to 640x480 and crop the video to 640x480, V5 completely re-processes it and this introduces lots of noise... and the video contains text and lines that need to be clear.
The original video is perfect in quality and all I want is to use the first 640x480 pixels without re-processing
However can't get V5 to just crop it
Any ideas?
Regards

Since you're changing the original file, you can't get away without re-processing.
What format is the original file? If it's an AVI, you might find that VirtualDubwill do a better job for you. If it's an MPEG-1, TMPGEnc is a good choice. If it's a WMV, then hopefully someone here has a suggestion for a good tool for that.

Thanks for your reply
The original file is a WMV, the content is mostly text so I really need good definition and the original as excellent quality!!!!
I run tests with Microsoft's WMV enconder and it works perfect for conversions, but it has no editing capabilities and I need to do some minor changes so I need to use vegas.
I find hard to believe that vegas can't do this... cause is a very simple process... just crop!!!
Thanks

Finally got the solution and Vegas5 works Ok.
The problem was that I was applying the cropping to the video TRACK. If I apply the cropping to the individual video EVENTs instead the quality is improved as vegas does a real cropping of the picture.
This is because when aplying the cropping to the video TRACK, vegas actually does a ZOOM of the area that I want to crop. While when applied to individual events it is a real cropping. The size of the final picture in both cases is the same, but for vegas the first one requires Zooming while the second methos requires Cropping.
That's it.

That's what the track one is called "track motion" & the event one is called "pan & crop." They do two different things.

I was going to tell you to do what you did, but i didn't read the thread until now. :)
