I've seen this effect is practically every music video... but I can not find any tutorials on how to do it, and I imagine it would simply suck if I had to do it manually.
Imagine 2 video clips playing simultaneously, and it rapidly flickering between the 2. Maybe go back and forth from one clip to the other 10 times in a second.
An example of what I am talking about can be seen all throughout this video:
Gucci Mane - Everybody Looking ( Official Video ) - YouTube
Just watch 15 seconds of it and you'll see more than enough examples of what I am talking about.
It also seems he syncs it to the snares in the back ground, or to the tempo of the beat. How can this be done without manually zooming in and clipping off miliseconds of clips?
On a side note: There's another effect I'm curious about.
From :29-:31 in the video, there's a part when the video seemingly studders going forward and reverse back and forth where the lamborghini is turning.
Can any of these effects be done in vegas? if so, how? If not, what program can?
