30fps anyone ??

[izanaki]

I don't know a lot when it comes to movies but from my understanding they are filmed at 24 frames per second. Are there any films that are 30fps or more? Is it on the horizon?

The reason for the question is 24fps goes into 120hz evenly but its still not exactly "smooth" compared to doing 30fps upsampled to 120hz or 60hz for televisions.

Thanks!

"Oklahoma!" and "Around the World in 80 Days" were shot using the original 65mm Todd-AO format (which was conceived as a 30 fps format). They both had to be shot with a second camera at 24fps in order to be shown not in the "roadshow" theatres. Given the huge cost and difficulty in that method, the Todd-AO format went to 24fps after those two films.

Since then, everything has pretty much been 24fps for film. There are possibilities for change as cinema moves into the digital realm, though. My understanding is that DCI's (Digital Cinema Initiative) current proposal calls for 2k and 4k digital projection at 24fps and 2k digital projection at 48fps. All other framerates are precluded. 48fps standard can be used either as a way to project in 3d, or simply to double the frame rate. 25fps, 30fps, 60fps, etc, all would need to be reformatted to either 24fps or 48fps for digital cinema exhibition.

So, really, it's just 24fps at the moment (with the possibility of 48fps on some upcoming presentations). But Blu-ray spec is limited to either 1080p24 or 1080i30, so there's not actually any way for it to handle 48fps anyway.

I agree, though, 24fps isn't completely smooth... but it does look "film-like." If you've ever seen a demo of something like Super Dimension 70, it really is amazing what higher framerates (and larger film stock) can do.
