Quick question for Final Cut Express 4

[JamesDV]

I was wondering if anybody could tell me how to apply an effect to a certain area of the clip but not the whole clip?
To do this, the first way that would come to mind would be having 2 layers of the same clip, cropping out, say, a quarter of the clip (as the second layer) so you have the whole clip uncropped as a bottom layer, and the top layer being a cut-out section of the clip, and applying the effect to that layer.
I know it's hard to understand what I'm talking about but what I mean is like at several points in this vid (the first is about one third of the way through) http://movies.apple.com/movies/us/a...ess_tutorial_keyframeanimation_r640-10cie.mov where everything except a small section is darkened.
A better example is at 0:24 of this vid http://uk.youtube.com/watch?v=ZlVOSprPRcs&feature=channel_page where he's taken out a section, applied a red border and converted it to black and white. The effect in the youtube vid is almost exactly what I want to do in the in this vid I'm creating soon.

Any help would be greatly appreciated.
Thanks in advance

That's exactly the way I've done it. ( make another copy of the clip apply the filter, matte it )
I'm sure there are other ways to apply a mask "to the filter", so I'm curious to see there's a more proper way.

Well does anybody know of a more proper way of doing it? I know loads of other people are searching for a way to do this effect.
