Carlos Baena:

Anticipation:
(Reference: CGChar)

Every time you have a very quick move, you have to be able to prepare the audience for it, and know how to finish the move. It's the anticipation, action and reaction of things. You can totally have a 1 frame move, if you anticipate it properly, and cushion it or overshoot it properly. Sometimes, a action is not really about the action itself, but more the before and after of the action. That's when you are selling the action itself. Think Coyote, or TexAvery...they can have the character literaly dissapear in 0 frames...maybe just add some smoke from how fast they leave the screen. Yet, they know that for such an exageratted move, they need an incredible amount of anticipation...or sle audiences would be like "uh? what? what did just happened?". So it's important to not really think about it in terms of the action itself, but more the before and after the action. Theat's when you can sell whatever the hell you want to sell.
