how many fps is normal speed?

Post by Guest »

i was wondering what is the normal speed fps? Is it 18 or 24? Also if I was to match it with over dubing voices would it match up timing wise? Is there any small gauge film making books out there? Thanks and sorry for all the questions!

If you're just getting started with Super 8, look up Lenny Lipton's "The Super 8 Book". It answers many of the questions you will come up with in the near future.

Film speed depends somewhat on what you are shooting and what your end format and display medium will be.

"Silent speed", 18fps in Super 8, gives you a longer running time. It makes for a somewhat jerky look in projection or video; if you are shooting for the home movie look, this jerkiness adds to the authenticity of the image. An advantage of 18fps is that the exposure time is longer, so you can shoot in lower light.

"Sound speed", 24fps, is the same speed used in 16mm and 35mm sound film production. Movement is more fluid at sound speed. If you intend to blow up Super 8 to a larger format for theatrical display, you'll probably want 24fps. Film goes through the camera faster, so you'll need more film for the same length of time.

Back when magnetic striped sound film was available, filmmakers would shoot at either speed; 18fps was favored in Europe, 24fps in USA. Sound film is no longer made; you will have to either shoot "double system" with a camera and separate audio recorder, or add all sound in post production.

This post got me thinking (a rare thing). I shot my canon 814xls with 9fps at f1.4 inside a small cottage/diner at 4pm on wintery Howe Sound...you get the picture...may as well have been Sweden!

OK, I was thinking, upon playback, the 9fps is too fast if played at 18 or 24, but since I managed to RENDER an image to the film that was acceptable in exposure, now all I need to do is stretch the footage to make it more life like yet I still retain the exposure! I knew there was a reason I love both video and film. Now my question is, do I dodcap this thing at 18 or 24 or 15/16fps to convert to 29.97 video tv presentation? :oops:

Oh, feel free to use my idea - I am sure I am the first that ever ever ever thought of this.

keep on filmin'

If I understand you correctly, what you need to do is use DynaPel's MotionPerfect (or similar software package) to create in-between frames (interpolations between each of your original frames). At that point you will have video that is equivalent to what you would have had if you had shot the scene at 18fps. Then you use Dodcap/Cinecap to do the speed adjustment to 29.97fps. (Please note that MotionPerfect does a good job in most cases, but not always.)

A more simple minded approach would be to first Dodcap with 15/16 and subsequently with 18fps, but this will look more jerky, since the first pass (15/16 fps) would just simply duplicate each of your original frames.
