Video editing and enhancing

[Videographer]

1. I use Sony Vegas Movie Studio Platinum 10 and recently I transfered an old black and white 8 mm movie to DVD. The original 8 mm film is scratched, sometimes over or underexposed and therefore the DVD copy is likewise.I'd like to enhance it using the video software that I use. My first question is; are there any free plugs in that I can use with Sony Vegas to clean the video copy of this film and second, if I want to use a video FX to apply to a certain portion of the video only in order to correct the original exposure of the 8 mm film like brightness, contrast, etc how can I select the specific portion of the video and apply the effect to that portion only and not to the whole clip, because I think --and please correct me if I'm wrong--that if I drag the Fx effect to the clip, the effect will be applied to the whole lenght ot the clip. One more question; if I want to edit out a part of a video clip and I know that the part I want to remove starts at 00:00:00 and ends at 00:00:20, if there any way that I could use those figures to edit out that especific part?, like an editing feature in Sony Vegas where I can enter those figures and then remove those 20 seconds of video. If not, what video program does this? a professional one may be?
Thank you all for your answers.

Or Avisynth as second choice.

Vegas is an editor -- wrong tool for restoring video.

You simply zoom way into the timeline and split it where you wish. Then you can either mess with it or hit delete. It's a lot quicker to use editors if you study the keyboard shortcuts.
