it tends to be the camera more often. super 8 does not have a good pressure plate design. even Bolex H16 cameras were redesigned in the mid to early fifties. they upgraded the gates and the prussure plate as well as the claw. but, aside from all that, film will weave. i see it in the theater when watching first run films. in some twisted way, i kina like it. as long as i don't notice it until i look for it.
