Found your channel from your comment on the high speed camera teardown, all your footage from high speed and normal speed cameras is great! You seem to be a big enthusiast in them - and pinball! Just wondering, why does the mirror move back and forth? Did Arri patent the mirror shutter or something and they had to do something else? I figured splitting it up like this wouldn't be desirable at all, especially since this camera was made with a mechanism so silent it didn't need a blimp. But this adds another thing that spins and moves back and forth.
Well it's possible this helps make it even more quiet, but I think really the biggest advantage is that it is way more compact. Compare an ACL to the Arri 16S, for instance,. That angled spinning mirror takes up a lot of room. Secondary benefit: when an ACL shutter is closed, no light reaches the film. When an Arri 16S shutter is "closed" light can still leak around the mirror and expose the frame of film sitting there. (Really only a critical issue in things like time lapse and stop motion.)
