This sounds to me like the mag isn't quite securely fastened. I'm pretty
sure there was a thread on this very subject on one of the cml lists quite
recently regarding Arri cameras/mags. Perhaps the operator isn't too
experienced with Arri cameras.
I've seen this problem from time to time with film recorders, where it
takes several seconds to expose a single frame; normally not a problem,
but when the film is stopped while the recorder recalibrates or renders a
slate, you get exactly this effect.
I'd suggest searching the cml archives.
