IŽll be shooting a movie with the hpx500 in january.

The final product is supposed to be shown on the big screen in Europe and the US.
We donŽt know yet, wheather we can afford a blow up on 35mm.
So the material should also work fine with a digital projection and should be able to be transferred to a PAL and NTSC SD-DVD.

Is it better to shoot 24p or 25p?
Any suggestions?

Thanks.

If you're planning for NTSC or a US film print, then shoot 24p.

If you shoot 60i or 50i, you could convert to either PAL or NTSC easily.

24p to 25p is indeed very easy (4% speed up or down) but 60i to 50i is not that simple. 24 to 25 or the other way is only one frame differance but 60i to 50i or 25 interlaced frames to 29,97interlaced is 5 interlaced frames differance and need a good software for that.

And take a big resolution hit when you convert to 24p or 25p.

Hmmm. I really won't compromise the quality of my DVD motion for the sake of theoretical printing to film or digital projection. Let's face it, the money is in DVD sales. But that's not the question you asked. Many apologies.

@David: What do you mean by "taking a big resolution hit" ?

Thanks for all the replies.

Converting from interlaced to progressive involves deinterlacing; this will result in resolution loss because you either try to make a whole frame out of half of one, or you have to blur two interlaced fields together to avoid comb artifacts.

How would it compromise the quality of your motion on DVD to shoot 24p? Hollywood movies are 24 fps from the beginning to the end of the process; I don't think anyone thinks their motion is "compromised" on DVD . . .
