fps question for PAL shooters

[/p/]

I'v been wondering about video frame rates for a few days now.. Here in Aus we use PAL which means most cameras come with only 25p and 50p options. I was under the impression if I wanted to put something onto a DVD to play in a DVD player or put something on television it would have to be shot at 25p (maybe 50p is acceptable for TV too? Both are fine for DVD) also I was under the impression that you need 25p and 50p to avoid strobing issues.

 

BUT.. Most of the shows I watch on tv are American.......... Also, aren't most movies in Hollywood shot at 24p? And they work fine on a DVD???? I am so confused. Not only that I'v tested 24p 30p and 60p under fluorescent lighting and as long as I double shutter speed (24p 1/50th, 30p 1/60th, 60p 1/120th) I couldn't see any strobing at all.. You get strobing if you don't double your fps with your shutter but that also happens with PAL versions......

 

Can you put 24p onto a DVD and watch it on a PAL DVD player? And what's the deal with the TV stuff? Is there any reason not to shoot at 24p if you don't plan on putting your work on TV?? 

 

Sorry, just confused myself with all these questions.

 

FOR PAL PEOPLE BUYING BMPCC Are you going to shoot 24p or 25p? Why?

your PAL dvd is 25fps

your American films / tv shows are converted from 24fps for films and 30fps NTSC for tv shows to 25p as the dvd is authored

 

I have to make dvd masters for different regions to conform to the spec for each region each time I release a dvd worldwide.

 

but yes yo can shoot 24p if you want to -

If you are wondering why PAL is 25/50 & NTSC is 30/60, then i seem to remember that its all to do with current/power differences between continents.

24fps is all to do with projectors & nothing to do with TV at all.

As mentioned before, the DVDs you buy over there have been converted to 25fps.

 

With Blu-Ray and HD, each system can play any frame rate, so movies can be stored as 24fps, there's no PAL/NTSC anymore, only the region lock, but it doesn't affect the contents.

 

As for strobing... doubling the frame rate for the shutter is supposed to emulate what would be the 180 degrees shutter on a film camera, it's got to do with cinematic motion more than strobing. What causes strobing, or flickering, is using a shutter speed different than your current frequency (50hz in PAL regions, 60hz in NTSC regions). Shooting 25fps at 1/50 will be perfectly fine for you, however, if you take your camera to the US (or any other NTSC region), even though you're still shooting 25fps, you'd get better results using 1/60 as your shutter speed (assuming there's artificial lighting of course).
