What editing system is used for this

Or what editing system can do these things?

me and my friends really wanna do this but All I have is iMovie.
I also have an iPad and iPhone if that helps.

I couldnt watch the video, but there's a good iPhone/ iPod app called Splice that i use. Key is, if it's longer than 3 or 4 minutes you should make like three clips of like 3 minutes. Itll make it go faster

I think they used Windows Movie Maker with a few add-on effects. There's nothing really that fancy in it so you could probably use iMovie to make the same kind of thing.

It's not very complicated. You can record a video on your iphone. Send it to your laptop and edit it using various software like Vegas pro 12, iMovie, Adobe Premiere Pro or Adobe After Effects.
