Well shooting with 60fps instead of 30 would be better for making slowmotions, however I would have to cut down the resolution (shooting with 60fps means 720p instead of 1080p as it is now). Having the resolution to be 720p unfortunately makes the cards look less detailed, due to the Moiré-Effect (quite a problem for DSLRs). Thats why I rather shot the footage with 30fps.
The name C.O.F.F.E.E comes from the scripting language "Coffee" that is part of the 3d programm Cinema 4d, which is the programm I use for my 3d work.
Glad you liked the tutorial.
