Some time ago, I helped Ed with setting up those dimensions for the
5000F by scanning the whole platen with film holder in place with film
in it so he could get the dimensions right. I know he was working with
other(s) on the 9950F at that time. I heard on a fourm that he had it
working. You might drop him a line. He is incredibly responsive with help.
I think what you want for a flatbed with multiple frames at once is not
Auto Crop. In the Input tab, select Mode: Transparency. A new box
labeled Film Holder then appears with selections for the various film
holders that come with the scanner. At least on the 5000F, they are very
accurate. That may deal with your problem of getting only the images,
and not the holder, in the scan.

Nope, I understood, I was just mouthing off about how to make batch
scanning less time consuming in VueScan.

CanoScan may be doing some noise reduction too. They are tricky devils.
VueScan also has a noise reduciton feature, but I've never used it.

NO, NO, better than that! You can batch scan the whole 30 frames into
separate files, RAW and/or TIFF and/or JPEG, all at once and unattended.

Nope, once you pick a film holder with multiple frames, the Batch Scan
option boxes will appear. You have never seen them with the FS2710 (I
know, cause I have one) because it can't do batch scanning. With the
FS4000, which can scan a strip of 6 frames or four slides automatically,
the VueScan input window has batch options. I just set Batch to All and
walk away for a bit while it scans all of them into separate files. So
get out of Mode: Flatbed and into Mode: Transparency, then select the
proper film holder. You will find a whole new world. I told you Vue Scan
is a complex thingie!
