30fps vs. 24 fps?

Hi,

We're starting to animate our final project for class, and we're wondering what difference it makes to use 30fps or 24fps. Obviously 24 is film and 30 is US video, but does that matter when you're working with 3D? If we render in 24fps, will we have trouble putting it on a DVD and watching it on a TV set? Would animating in 24fps save us time, since there would be fewer frames?

Thanks!

I thingk PAL is 24 and SVCD is 30.
Go with what suits you best I would say.

PAL (UK TV) is 25fps, because their electrical currents run at different cycles than ours.

So now my group is thinking that maybe we can render and play our movie at 15fps, saving us half of the rendering time. Would this work? Would it look really bad with motion blur and stuff, or would it be the same as shooting on twos in 2D animation?

You are delving into a very complicated and intense subject here and the question cannot be answered with a simple yes or no.
If you are planning to view the finished video on a pc then you could really do it at whatever FPS suits. However if you are planning on putting it on DVD that is a different story as the video and audio have to be a specific type and standard (ie. you cannot use any audio other than MP2 for a NTSC 29.970fps dvd)and the video standard has to be mpeg 2 otherwise a standalone DVD player will not play it.
Most new European players will play NTSC or Pal, but from my understanding it is harder to find a player in the U.S that will play both colour systems.
15fps is not a good idea for finished playback speed in general because of the motion blurr problems and it will be difficult to avoid it being jerky...ect.
Hope this help...goodluck.
