A tool for video similar to audacity?

[Bill Davidsen]

Is there a simple to use video tool similar to audacity? I have a fairly 
manual way of pulling snippets of good material out of a stream of 
mostly crap, but what I would like is an easy to use way of finding the 
start of the undesired material with drame by frame stepping, marking 
it, finding the end, and then just removing the unwanted material with 
some nuke-it feature.
