Technical Explanation
Stop motion animation can create a disorienting, and distinctive, staccato effect, because the animated object is perfectly sharp in every frame, since each frame of the animation was actually shot when the object was perfectly still. Real moving objects in similar scenes of the same movie will have motion blur, because they moved while the shutter of the camera was open.
Go motion was designed to prevent this, by moving the animated model slightly during the exposure of each film frame, producing a realistic motion blur. The main difference is that while the frames in stop motion are made up by images of stills taken between the small movements of the object, the frames in go motion are images of the object taken while it is moving. This frame-by-frame, split-second motion is almost always created with the help of a computer, often through rods connected to a puppet or model which the computer manipulates to reproduce movements programmed in by puppeteers.

“A technical objection is the first refuge of a scoundrel.”

“Are cans constitutionally iffy? Whenever, that is, we say that we can do something, or could do something, or could have done something, is there an if in the offing—suppressed, it may be, but due nevertheless to appear when we set out our sentence in full or when we give an explanation of its meaning?”
—J.L. (John Langshaw)
