I have a problem with the Arri cam.
The camera is stuck on "wind" when I load a mag. Sometimes it doesn't, but the mag jams after running the film for a few seconds. I hear a scratching sound in the mag.
When I load the film, I make sure to roll the take-in core several times to make sure its tight. Then I close the mag and pull out some film from the feed side to make a bigger loop.
When the camera jams, I open the mag in the changing bag and the film in the take-in side is either loose or "spaghetti".
What is going on?
