The Slide

One of the main effects of the video which I also did in my first edit was the "slide" of the chaser when he was coming round a corner. I got the idea from one of my research videos, "Dubstep Guns", where one of the characters slides round a corner without moving and then raises his guns up. I'm not sure exactly how they did this, but I had a good idea as so how. This was one of the more labour intensive effects to do, however due to its un-realism, it works well in a music video.

I used After Effects CS5 for the compositing, these are the steps I took to make it

The first thing i had to do was film a clean plate of the background and then film the actor on a green screen so I could easily seperate him from the background.

I masked out just the actor and some of the green leaving the clean shot to show through.

 Using Keylight, I keyed out the green from the actor so it now looks like it is just one shot and not two layered.

In order to actually make the slide, I keyframed that layer with the actor on it to come in from the right of the screen. Motion blur was added so it looks less fake and then I ramped the speed

To make it look as if he was coming from behind the wall, all I did was duplicate the clean plate, mask out the wall section and put that on top of everything.

Finally I added a shadow to follow him, keyframed the camera to bulge in and out and then added it to my edit.
