16mm
Frames Per Foot
Published : 4th June 2004
Hi All :
Momentary brain freeze.
I'm trying to calculate time-lapse film consumption and I
want to check my facts.
16mm film contains 36 frames in each foot, right?
If I'm wrong, I'm going to blame my expertise in Digital filmmaking
for making me forget
Thanks

Thank you...
Now I can do my math and go to bed...it's been a little too
long between jobs with sprockets...
Thanks..

Time to replace the blue belt inside your CP16R, Joe -- they
rot every few years...and can cause damage when they disintegrate.

Kodak has a very handy on-line "Film Calculator"
that calculates running time, film length, etc., for almost
every current film format and frame rate. Here's the link

Forty frames per foot, as Jeff said. However, the number 36
is also relevant and maybe why it stuck in your mind. That's
how many feet of 16mm film run through the camera every minute
when you're rolling at 24-frames/sec. For 35mm it's sixteen,
4-perf frames per foot -- 90 feet per minute at 24 fps.
Handy numbers to remember when you're calculating shooting
ratios.

16mm :
40 frames per foot
36 feet per minute at sound speed (24fps).
35mm : (4-perf)
16 frames per foot
90 feet per minute at sound speed.
Cheers....

There is also a time-lapse calculation chart on page 893 of
