I think he took a screeny of every frame and then put it into a .jpg or whatever slide show, and then saved it as a gif?
Although, I have no idea what I'm talking about.
So, I might, just might, be wrong.
Also, it's a cool gif, Luciano, mind showing me how to do one of those? <;

Shit, Hours.
Loved that one.
I don't care too much about effects in the video.
I only care about camera-work, sync, good and/or fitting music, and good replays.
And that, my friend, was all of the above.
