The Perfectone that I know of is a sync motor, that is it's a more or less accurate speed motor with an AC generator on it that provides a sync tone to a recorder.
It's not a crystal synch motor; if you use it for sound you will need a recorder which can accept pilot tone input and some way to resolve the tone when you transfer your sound to synchronized media. Crystal synch was a great revolution when it became available in the early seventies, because it allowed the camera operator and sound man to walk around without an umbilical cord connecting them, carrying pilot. --scott _______________________________________________ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
