I'd appreciate observations on choosing a frame rate when the end product is both NTSC and PAL video.

Thanks.

Basically not 30 fps.

Doesn't really matter whether you shoot at 24 or 25 fps -- the most common method of transferring 24 fps film to PAL is to just run it at 25 fps, so it's really more of a sound issue than an image issue. And probably if you shot at 25 fps, for NTSC you'd run it at 24 fps and add a 3:2 pulldown for 60i.

So the question is whether you want the movie to be slightly sped-up in the PAL version but normal-speed in NTSC, or normal in PAL but slightly slowed-down in NTSC.

The question is whether this is a finished, edited film master, like a color-timed IP, and you are making separate NTSC & PAL transfers, or if this is one transfer that you need to convert to various other formats. Because if that's true, you're probably best off transferring to 24P HD and making NTSC & PAL downconversions off of that. Second best would be to transfer to PAL and make NTSC off of that. Last choice would be to transfer to NTSC and make PAL off of that.

Hi,

I would shoot 24 0r 25 depending on hz of the electricity in the country I was shooting.

The 4% change in speed is not a big issue, the sound should be pitch adjusted.
