If you mean the rainbow background, it's a green screen shot. I'm sure you can Google some tutorials on the technique.
Thanks for the answer.
My problem is not to put a person in the clip. Just Imagine the video without the person in the front, just the expanding rainbow lines in the back. Maybe I should make a post in the Photoshop forum, because if I dont need the expanding thing, just the rainbow stripes, i could use a picture, but i still have no idea how to create such a shape symmetrically correct.
That rainbow background is likely a purchased clip, something the guy bought and added to his video.
With some diligence and patience you can create those shapes even in PrPro Titler. Then animate them with keyframes - such Motion effect properties as Position, Scale and Rotation is at your disposal.
So as to be able to rotate all those shapes as a group, place them in a separate sequence (nest them), and then manipulate Rotation property of that nested sequence within your master sequence.
It's definitely easier (i.e. more convenient) to create this animation in After Effects.
If you need some sort of shapes precision, create them in Illustrator and then import into After Effects.
Hope, this gives you a start.
Thank you very much. I didn't work with Illustrator yet, guess I'll start now .
