I used to video edit, and I can't see any split frames or anything. If it's edited, the editor has a sure job ready after college. If not, freakin' amazing.
I do think it's real. But I also think there's about 1000 missed shots per succesful shot. That's where my "too much time on their hands" comment comes from.
There's a TON of editing going on in those videos. That guy is a professional skater and not just some chump in a college house. Him and his friends have lots and lots of editing equipment for their skate videos.
These guys use a bit bigger ball but hey... it's still amazing.
I saw these guys on TV doing a shot from the upper deck of a stadium - it was no BS, into the drain! They admit there are plenty of misses that never make into the videos but they swear all the shots you see are real.
