n. A specialized type of negative film stock that is part of the intermediate process that goes from an original negative to a release element (most common in the motion picture film post-production process). The material used is itself the same as in an interpositive. The differences is that an IN has a negative image on it, while an IP has a positive image.

"They can always drop frames to film out from the digital interpositve at 24fps without needing to worry about skip printing from a film internegative, but high-end LCOS projectors and Blueray are already 60p capable. 48fps is nice for Maxivision and backwards compatibility, but not necessary if we're going to digital."
