How To 'Roll' Clips [Vegas]

Okay this is going to be hard to explain but I'm hoping the majority of people will click onto what Im asking.

There was a really good tut for this up on youtube but it seems to have been taken down and I hadn't had a chance to try it out.

But what I'm looking to do is 'Roll' Clips basically have more than one clip of difference scenes roll kinda like a film... most people do this using a film strip image...

Im hoping I explained what I want to be done well enough and Im hoping someone knows how to x]

Hm....well, I for one, never have done this. Though, I'd suggest that you make at least five tracks. Put the clip you want on four of the tracks. Make sure they are about the same length. Then put the film strip ontop of all of them on the first track . Make the flimstrip transparent so you can see what you're doing on the other tracks. Use track motion to mess around with the settings. Make sure it's the same ont he other tracks except for position to make them aligned. Do the key-framing to make each clip move towarda direction and have the film strip move and wala? That's my guess on it

Something I do in Adobe which could probably be replicated is take an extremely long chunk of whatever you're editing with, and speed it up so much that it looks like clips are flickering... but that only works with really fast film rolls. If you want a slower one, you gotta do it manually.
