  Feet & Frames in 16mm?

  Posted by Sebastian Leda on July 8, 2005 at 4:17 pm

  Is there a way to display feet & frames in the timeline for a 16mm (20 frames per foot) project?

  I can only get it to display 16 frames per foot.

  16 frames a foot is for 35mm film. (24fps x 60 sec. = 1440 frames divided by 90 feet per minute = 16 frames per foot) 40 frames to the foot is 16mm. (24 fps x 60 sec. = 1440 divided by 36 feet per minute = 40 frames per foot) I don’t know what 20 frames a foot is. (Could be 16mm at 12 frames per second?)

  You are right. There is 40 frames per foot in 16mm at 24 fps. But when I did the setup in Cinema Tools and FCP the only options I get is for 16mm 20 (i’m not sure how is this related).

  But it makes sense with the keycodes, they advance one foot every 20 frames. After 0000+19 it goes to 0001+00. But the feet & frames counter in the FCP timeline goes 0000+15 and the next number is 0001+00, which is ok for 35mm but not for 16mm in relation to the keycodes.

  Does this makes any sense to anyone?

  16MM 20 means 16mm with 20 frames between keycodes.

  There are still forty frames in a foot, but there are two keycodes in a foot also.

  So if you are rewinding 100 keycode numbers, then it would be 50 feet. Of course, you’re on a computer, so why am I talking about rewinds?

  Ok, now that the whole 20 frames 40 frames issue is clear, can I make the FCP timeline give me 40 frames per foot display on the timeline? or 20 frames per keycode? or any kind of 16mm related reading?

  I can only get it to display 16 frames per foot which is for 35mm.

  Thanks,

  OK this looks like a bug. I don’t have FCP 5 yet, but in FCP 4.5 if one put a “Timecode generator” filter on a clip and switched to 16 mm, you god 40 frames per foot and the feet+frames counter incremented to a foot after 39 frames.
  I know this is not like the timeline footage display, but at least it understood 40 frames per foot. Make sense?

  Thanks, I didn’t know that. Now I found a workaround. I made a nested clip and applied that filter. It’s not as good as having it display in the timeline, but at least now I know the size of my reels in feet & frames!
