When I received my scanned footage (Kodak 7203) back from Spectra, they indicated "camera flicker." It's inconsistent (not in all shots) but very noticeable towards the end of my edited footage: https://vimeo.com/170814555.
The camera is a Bauer C61XL. It has a low-light, 225-degree shutter. When I looked at the problem shots frame-by-frame, it was clear that the exposure was inconsistent. It reminded me of the flicker in an old wind-up Bolex. Can others confirm by looking at the footage that the shutter is the likely problem, rather than something else? Otherwise, the scanned 7203 looks very good.
