Mixing 24fps & 15 fps?

Let me freely admit up front that I'm brand new to this moving pictures thing;

Hi, my name is Jon and I'm a still photographer.

All right. With that out of the way, my question (in what passes for my mind) is simple - If I shoot footage with a Nikon DLSR @ 24fps, can I also include in the finished piece footage that was recorded at 15fps using a Canon G9 point & shoot without major issues? I've not started this project yet, but there are places where the G9 will simply be much easier to put in place than a DLSR.

I did try searching but perhaps I had too many variable in my parameters and ended up not finding much here. I'm more than happy to go off & read on my own if someone can send me a couple of pointers.

Many thanks.
 
technically it's not a problem in any nle i'm aware of, but the 15 fps stuff will be jerky of course, especially in comparison, unless you play it back at 24fps but then it will be slow instead.
 
What NLE are you using? Your best solution would be to interpret the footage (easily done in FCP or Premiere) to 12fps. That way when you drop it onto a 24p timeline it won't have ugly blended frames. Footage with a frame rate that slow will not look natural but will be ok for certain purposes. I've used 8fps stills from the 7D to create an old style home-movie look in surf videos by playing them back in a sequence with a still image duration of either 2 or 3 frames (3 frames on a 24p timeline = realtime).

You will need to somehow convert the 15fps footage to 24fps footage to be able to freely edit the two together, there are a number of methods with 'pixel motion' type algorithms being the best (Twixtor, Timewarp . . . etc).

15fps played back at 24fps will be faster not slower.
 
yeah i realized that when i hit post but it was such an obvious mistake that i was sure he'd get my point, in any case he will notice. ;-) anyway, since we're concerned with correct info here, you often don't have to convert, many nle's do that on the fly, fcp even intelligently so with a little help from motion.
 
Thank you all for taking your time to answer my question. In the days since I asked, as you may be aware, Nikon has announced the P7000 which shoots at 24fps in 720p.

It should be on the streets in the next couple of weeks, just in time for the beginning of my project.

Problem solved!
