Cintel Scanner capturing full 35mm (+edgecodes)

Hello, I have the desire to capture the full 35mm (image + soundtrack + sprockets) of a film to document the edgecodes and other parts of the film not normally seen when projected.

Am writing to see if someone in the community has done this with the Cintel Scanner or to learn/figure out what steps might be taken to accomplish the task with that machine.

Can it be done with the machine straight out of the box? Can the focal point be raised high enough to get all 35mm not just the 22mm of the typically projected image?

Would it require the machine to have an additional lens to achieve the zooming out?

I do not have day to day access to the scanner, so am hoping to achieve a better understanding before purchasing some machine time.

Thank you for your expertise and suggestions.

Anything is possible, however anything you do to achieve that will require invalidating the warranty and will cause the image stabilizer etc.. not to function basically rendering the machine unusable.

What type of codes are you trying to capture? Does the Cintel Audio and KeyKode reader not capture the codes in question?

I am interested in the production history of a film, so I am doing the academic exercise of documenting the edgecodes (generally Eastman/Kodak film stocks from 1974-1983) for each of the films generations (in-camera negative, post production work steps, interneg/pos, final theater print) with the goal of identifying when the film changed and to learn about the work involved in the early film print versions which was lost as the film evolved afterwards.

An example of the edgecodes to read/document:
[1983 Date Code with an earlier generation EASTMAN film stock underneath]

Will be finding out if the KeyKode reader can produce consistent results. But as many of the codes are written on top of each other and are faded to different degrees, much of this research/verification might end up being looking at the full scans, as the prints suffer from VS and are difficult to be around for long periods of time.

So asking if anyone else has done the full edge to edge 35mm capture or something similar with the Cintel Scanner, or maybe a combination of Black Magic Design equipment. Can the Cintel be sync'd with another Black Magic Design camera so they share the same shutter speed? While the scanner worked in it's traditional functionality, a second camera could be doing the full capture a few frames behind.

Thank you,

Hopefully the audio and keykode reader can do the trick, it's meant to work on all film types, but yes, if they aren't 'barcode' format or are overwriting one and other might be tricky.

There is a 'bi-phase sync' output on the Scanner which could be used as a synchronizing pulse to other cameras, it's configurable to 1/5/10 etc.. pulses per frame.
