Zero Cut
A method of negative cutting specifically for blow up, where every shot is given Frame Handles so that the registration pin of the printer is never engaging with a splice, which can cause the image to wobble at the cut. It is most commonly used when you are blowing up from 16mm to 35mm. Zero cut should be done only if really necessary, because the lab can only print the film as an optical, which is far more expensive than a contact print. Zero cutting is a little more complicated than standard A&B rolls, so the negative cutter also charges more for it.
