Weird, Unexplained Darkening

[Kaboom]

So I'm in the process of editing an AMV (which I am now finally back to doing now that my laptop is up and running again... hooray!). Things are going smoothly, until something weird just happened, and I'm not sure how.

For some reason, Vegas has suddenly started darkening one specific little chunk of footage for no apparent reason. Take a look at this screencap. The one shot of Goku with Nyoi-Bo is the one I'm talking about.

When I view and play it from the Trimmer in the bottom left, it's fine, and the thumbnail for it is the correct color when I put it on the timeline, as well. But when I view it in the timeline, it's darkened, as you can see in the lower right. It renders that way, too.

I'm showing the FX Window for the clip, and as you can see, all I've actually done to it is add the slight radial blur, Which doesn't seem to be related to the problem, as removing the filter doesn't change the colors, and the colors are even wrong when I retake out the chunk from the AVI and put it on the timeline. Only thing I can think of doing is rerendering the AVI for that part of the movie, or using some brightness filters to try to fix the mysteriously darkened filter.

But still, that and only that one, little, 5-second long chunk of an otherwise unaffected 15-or-so-minute AVI is being affected, and only when I put it on the timeline. And it wasn't doing it before; it only started just the other day. Does anyone have ANY idea whatsoever as to what could be causing it?

EDIT: Actually, upon further testing, I have to amend that. It's doing this darkening for ANY clip I pull from the AVI, but not to any from the AVI that are already in the timeline. I tried re-rendering the AVI, but that didn't change anything. I'm gonna try using the AVI in another project, and see if that does anything differently...

Well, looks like I fixed it. I still don't know why the original clip was acting up. I had it rendered using HuffYUV, but now with it rendered with Lagarith instead, the problem's disappeared. Weird, but I guess the problem's resolved...

IMO it looks better dark; looks more like a flashback.
