We're doing some restoration work on a 35mm feature right now that was scanned on an Arriscan (at another facility), at 2k. The source was an IP, so no physical splices in the film (or at least if there are, they're rare). At every scene break, we're seeing warping along the lines of what you'd see in a Spirit or other continuous motion line sensor, only it's on the whole frame, not just the top/bottom of the frames surrounding the cut. Sometimes it's on the first frame after a cut, sometimes it's on the second. But it's there every time, and is really noticeable on shots where the camera is locked down. Here's the really weird bit - our client went back and looked at other scans they've done at the same facility, from prints, IPs and cut neg, and all of them have the same problem. I don't really know a lot about the Arriscan, not having used one personally, but how would this happen in a pin-registered scanner with an area sensor? Could it be related to the microscan sensor repositioning they use? If so, why would it only happen at scene breaks (and again, no physical splice in the scanned element, since it's an IP) Any ideas?
