One other thing to remember... the very early hand cranked cameras gave some freedom to the operator to crank at different speeds. If they got excited... I believe they cranked at bit faster... wouldn't you? Second point... on the pull back up on any crank the speed would be faster... ever use rewinds on a bench...? They attempted to keep the speed even but there were no controls at that point that governed the speed... hence the later need for spring drives and constant speed etc. I agree... this "new" system sound a bit strange. What you would really need is a variable/non variable human to crank both the projector and the camera during the transfer to video. Anybody talkin' to the Lumieres or Latham these days... they may have the answer? ---- To signoff SCREEN-L, e-mail [log in to unmask] and put SIGNOFF SCREEN-L in the message. Problems?
