Commonly, in working terminology, “rolls” tend to imply factory sealed/originated raw stock, which is yet to be or recently shot (including daylight camera spools, which sometimes do exceed 100’). Generally. Super 8 could be an exception but I still say roll.
Reels usually imply projection. “Rolled” film certainly exists after processing and can be stored on a film core in a can / box but require reels for actual projection. Definitely accurate that rolled film could apply to film as prepped for viewing on a flatbed Viewing system(Steenbeck/KEM or similar), which typically does not require reels. “Rolls” predominantly describe camera-ready entities I think due to their minimally prepared state (no “reel” as such, but again many times actually on a spool in 100’ lengths). Fresh film wound onto a 2” core minimizes the contact that the raw stock has with abrasive surfaces and decreases mechanical/camera noise in sync cameras where that issue can matter quite a bit.
