Cinematography : Film Projection Question by Christopher Binder

Film Projection Question

I'm a little bit confused. Traditionally a 35mm film camera can record 10 minutes, so if a film is 120 minutes long, in terms of reels that means it's 12 reels long right? But I've seen in cases things like a film is really long in terms of minutes but in terms of reels only listed at something like 4 or 5 etc. Can somebody clear this up for me?

Print and camera raw stock are 2 different things. 35mm camera raw stock is slightly over 11 minutes for 1000' at 24fps and using a 4 perf pulldown. Print stocks for projection are usually 2000' rolls so 22 minutes maximum if the editor uses absolutely all of the available footage.

At 24fps and four sprocket pull-down is 90 feet per minute.

When your finishing on 35mm, your editor edits on reels, each reel should not be longer than 20 minutes, so if you have a 120 minute film, you'll end up with six reels.
