any way to 'de-grain' zoomed in footage?

Hey all,
well, getting close to finishing my first AMV and there are a few scenes that I'm using that are zoomed in (selecting a rectangular area the same ratio as the full frame and stretching it out to full screen so it isn't stretched, but just zoomed in). The effect is what I want (just centering on the important area of the original clip), but the image is now grainy.

Is there any way I can minimize this or is this just something that I'll have to live with?

Thanks in advance!

Well, short of exporting the clip, cleaning it with AVISynth and reimporting back into the timeline, I can't think of any way, unless there's an option in the zoom dialog to not do some operation or another when zooming.

hmm, I could take the clip into AVISynth, but what would I do with it once I got there? As it is my editor that is doing the zooming (Magix Movie Edit Pro 10), I'd have to either clip the file in AVISynth (making it smaller), resize it back to full screen, and then apply some sort of blurring or somesuch filter (no idea)...

so, anyone?

I was referring to taking only the small part you were zooming, exporting it from Magix, opening that in AVISynth using deen() or other type of smoother, and then importing the cleaned clip back into Magix and putting it where the effect is supposed to take place.

Or you use VDub for this task. There exists an external filter "Zoom" (maybe you must download it). I used it for my last project, it seems to work well.
