How Is This Effect Called or Any Tutorial for Adobe After Effects?

Question by Crystal C: How is this effect called or any tutorial for Adobe After Effects?
I want to add a effect to my video, the one that you see many times in videos or movies. When the person is in the middle of a crowd and he is saying something in a normal tempo, normally, while people actually go really faster by, faster than normal…

How is this effect done? Tutorial would be great 🙂

Or what is the name so I could find a tutorial?

This was copy and pasted. I think the name would be speed effects

If you have access to green screen, you can shoot your subject walking normally with the green screen behind him. Then you can shoot a “plate” which is a background of people walking on the street. Put the green screen shot on the track above your plate shot of the street and chroma key the green out. Then speed up the plate shot in the “Change speed” setting (right-click on the shot). That is not a “1 shot ” method, but it is how most filmmakers do it.
