I think he meant replay making but who knows here is how to manip in replays
Manipulations are when you hit uke to make him spin in the air.
Usually manips start slow then gradually get faster.
A tip for a better manip is to make uke spin in the air in the same direction.
I attached two replays one is a bad example and the other a good example.
ps larfen is the one true god of manips
