How do I clean up video with noise?

Every once in a while I get have some analog footage that has noise in the signal. I like to clean this up before I start editing. After I capture it, I run the raw footage throughVirtualDub with the Border Control and Dynamic Noise Reduction 2.1 filters to clean it up. Border Control allows me to remove the noise that often occurs around the border of analog footage. This is never shown by the TV so it’s OK to just blacken it. It also saves bits when encoding. Dynamic Noise Reduction is a temporal processor that compares frames before and after to determine what is signal and what is noise. It does an excellent job of removing analog video noise.

I also use that opportunity to trim the in and out points since analog capture is not that exact. Once that’s complete, I bring the video into Vegas and edit. If I had to color correct all my clips, I’d probably do the same thing. I usually capture a clip and then run it through VirtualDub while I’m capturing the next clip. So this really does save time.
