AKICWLJ-DW - Question for vidders.

I have a poor-quality video file with sort of muddy color, which makes it difficult to tell certain pale areas from certain darker ones. I need to heighten the contrast between them. In Photoshop, it's the sort of thing for which I'd use the Levels or Brightness/Contrast tools, but Windows Live Movie Maker does not appear to have either of these things. (Or, if it does, I can't find them.) Is there some piece of free software that would let me do this?

If it helps, this is a video of a forest with clearings in it, taken from above - the problem is that you can't easily tell where the clearings are. It was taken in the middle of winter, on what appears to have been a cloudy day, meaning that everything's just differing shades of brown and gray.

(I'm doing this for work; we need it for next week, and we don't think we can get a professional video editor in time. Obviously, this means that the IT person is in charge!)

Work-related anxiety.

I can't do anything about it, so I decided to get anxious about internet privacy instead, because of this sort of stuff. So I installed Ghostery and Do Not Track Plus, and switched my default search engine from Google to DuckDuckGo. Then I laid my bloody palm across my face and tore Google CEO Eric Schmidt to pieces with my bare hands, unless I in fact merely watched more Baccano! and subsequently confused it with real life. I'm worried that my personal metaphors may be getting too violent recently.
