VueScan, Nikon 4000 ED, half-frame negatives, again

[Hank]

I realize the "how to scan half frame negatives" question gets asked
and re-answered often -- I've read the backlog, try to keep up as
VueScan changes (grin). It is getting better

But, VueScan wants a fixed spacing; the camera doesnt' give one.

Fundamentally, the film camera varies a bit in how far apart the images
fall on the filmstrip, so setting any one number, while it works for a
while, eventually gets off enough to start missing the edges.

Can VueScan identify a bar of unexposed film (the same color as the
unexposed leader used to set the film base color)? Using the actual
(lack of) image content rather than the estimated distance to mark the
edges of a frame?

Has anyone found a way to get VueScan to show three or more half-frame
images at once in a Preview, so there is always at least one complete
image that can be selected?

Ideally, of course, I wish I could put the film strip, uncut, into the
slot of the Nikon scanner, open the exit hatch at the back side, and
get VueScan to simply crunch through taking every image, letting the
film spool out at the back on the pricey takeup reel Nikon sells.

There is a simple modification to the SA-21 adapter that will permit it
to operate just like the SA-30 so that you can scan an entire uncut
roll, without the take-up reel of course.

There are two versions, one completely reversible without opening the
adapter, the other more reliable but requiring access to the internals
of the adapter.

If you use the scanner on a bench, then the film can simply hang on
either side of the scanner. If not then a glass jar can be used just as
effectively to catch the film as it exits the rear of the scanner.
