What is the difference between 16mm films with a clear edge vs. one with a black edge?

Is one a copy and the other one an original? These would both be double sprocket, silent film positives I am referring to.

Usually the black edge, or rather, the surrounding region other than the image frame....would be indicative of a Reversal Film, either original or print.   Clear surround usually is a Negative, but if a Positive it would usually be a print, contact print if the emulsion position is inward....or optical print if emulsion position is outward.

Are you referring to the area in the "S16" or Soundtrack area? Even if the film is 2R (Double Perf) it may be from how they were printed.

Film can be printed with our without the optical track lamp lit even if the film does not have the optical track.

So normally on a 16mm sound print the optical track would be printed onto the edge opposite the perfs.

Sometimes prints get made as workprint or silent and the printer setup can then determine if that optical track area is clear or black. And if it was made with a IN and IP or other intermediate step.
