Derick Crucius Posted July 1, 2020 Share Posted July 1, 2020 Hey everyone, I wanted to diagnose a problem just to be sure all is good. I’ve always noticed a film burn line going along the soundtrack area of my 16mm film. My assumption is that it’s simply just the film getting flashed because I’m loading my daylight spoils into my bolex in daylight haha, but I just wanted to be sure that it doesn’t seem like anything else is going on here. It doesn’t seem to bleed into my image at all, so it’s not a huge deal. This film burn line seems to run throughout the entire roll. I just wanted to get some professional opinions. I have included stills from my scans as examples. thank you in advance! Link to comment Share on other sites More sharing options...
Doug Palmer Posted July 1, 2020 Share Posted July 1, 2020 I've had a similar effect with a bent spool. Before loading film onto daylight spools in the dark, I always make sure the sides of the spool are parallel, using a piece of 16mm leader held inside as a guide. But as it looks constant, maybe it's just light-fogging when loading the camera, worse obviously with fast films. Link to comment Share on other sites More sharing options...

That all makes a lot of sense, because I also break down all of my film from 400ft loads in the dark with previously used spools. I also noticed its a bit more prominent on the EXR 200t I shot.

Jordan Beard Posted July 1, 2020 Share Posted July 1, 2020 I'd guess that this comes from some light getting into the daylight spool while loading/unloading or while you were recanning the 400' reels. From my experience, in-camera light leaks aren't this uniform across the whole roll. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted July 1, 2020 Premium Member Share Posted July 1, 2020 Could this be a problem with the scanner / telecine? It's odd to see the whole frame plus part of the adjacent frames and yet the white corners match the scan area, not the camera frame. Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted July 2, 2020 Premium Member Share Posted July 2, 2020 Yes I’d check the film neg itself to see if that edge really is like that. Seems more likely to be the scan. Link to comment Share on other sites More sharing options...

On the LaserGraphis Scan Station (I scanned this with ) in overscan the white area is the gate aperture and you will see it move around as the scanner does realtime machine vision based "pin" registration, it is particular to this scanner.
