Is the variable shutter system of the Bauer A512 allows to film — streaming — with the adjustable shutter speed (in manual mode, without using the crossfade)?

Does the automatic exposure system is modified by the aperture of the shutter?

Does the automatic exposure system may be changed (by changing the internal settings of potentiometers) to make it compatible with the film Ektachrome 100D?

As far as I understand the 512a should in any case work with the 100D, it did not work properly with the 64T.
I never used the the variable shutter so I don't know this part, but theoretically the manually changed shutter angle should only give shorter exposure times but still correct exposure.
Try to frame an evenly light subject and and check what the automatic exposure says. with the manual shutter set to 1, it should show you 1 f stop more then with the shutter in open position.
If the f-stop does not change, than it will result in a fade out or underexposure.
