toymaker Posted November 23, 2022 Share Posted November 23, 2022 (edited) I'm not sure if anyone can answer this, and I'm not sure I even know how to describe it - or if there is a term for it. Sometimes when you watch movies on an old film projector, the image will seem to "drop" for a second. I'm not sure if it's the film slipping as it goes past the lens. Or maybe the speed isn't constant? Does anyone know what the hell I'm talking about? Is there an explanation for this?

TheGhostRider Posted November 24, 2022 Share Posted November 24, 2022 I'm not an expert on this but I think that's a common thing on film strips for the film to be not be stable all the time. I have heard that sometimes it can happen due to the frame rate being tied to it in someway. 1 Link to comment Share on other sites More sharing options...
goose Posted November 24, 2022 Share Posted November 24, 2022 From what I understand, the most common causes of film projector slipping are momentary changes in tension (which can usually be resolved through lubrication of mechanical components) or flaws in the film's side notches. 2 Link to comment Share on other sites More sharing options...
