I love this spot, seen it multiple times now, then again I am a DJ and have followed the Scratch Perverts for many years so the interest is multiplied exponentially.
I was reading about this spot on Motiongrapher, the director said:
"We shot the people spinning on turntables at 33.3rpm at high speed and then matched them to the turntables which were working with Serato."
such a smart idea to film them and use Serato (which also can control video via turntable) to create believable movements of the 'record'. Then use that footage and key out the green and composite. so cool!
