PAL versus NTSC Shooting
I am planning an upcoming shoot with my EX1 that will be converted to SD DVD. The potential clients are both from Europe, Australia, and North America. I am thinking of producing the DVD in PAL, but I need to know if NTSC DVD players will play back PAL discs. I know that many PAL DVD players do play back NTSC - but is the opposite the case. Just hoping that some of the guys in North America might be able to give me a leg up on this.
Any help is much appreciated.

My old US Pioneer DV-606D had no problem displaying PAL (or NTSC) video on a PAL TV; this may however be a different story on an NTSC TV. But "back in the day" you needed to be careful what you bought, video wise, and I believe the 606 was a 'multisystem' player.
To be safe I'd say produce the DVD in NTSC; PAL DVD players will play it back. George/ |

I'd advise against shooting any of the 60Hz frame rates in a 50Hx country unless you take care with your lighting choices. The rolling shutter in the EX1 makes the problem much worse as well. I'd suggest shooting 25p.
This can be slowed down to 24p for NTSC distro. You can put NTSC and PAL on the one DVD using a trick a learned of recently. You use a DVD10. One side PAL and the other NTSC. No room for a label though but a simple "If one side doesn't play, turn over" instruction is all you need on the slick. |

AFAIK 24p is not part of the DVD standard and you cannot use it; it's either 25p (PAL) or 29.97p (NTSC).
As for lighting flicker, it shouldn't be worse for CMOS/Rolling Shutter than with CCD's as your shutter is typically not synced to the AC. Use the Flicker reduction function from the CAMERA SET menu and set it to the appropriate frequency if you experience problems (flicker, banding). Some experimentation may be needed with the exact number (or try 'auto'). Filming under (old) fluorescent lighting may give you the most trouble as can HMI's. Tungsten and incandescent sources are usually fine. George/ |

It is my experience that at the level of 'consumer' the NTSC world is blissfully unaware that there is such a thing as PAL, and most NTSC gear is unable to play/read PAL material. There are odd exceptions -- some of the cheapest Chineses made DVD players are capable of playing back just about anything -- but in general the NTSC gear as found in North America is 'blind' to PAL. Twenty years ago the same was true of PAL gear when it came to NTSC, but currently almost any PAL player can play back, at some level, an NTSC recording.
As for shooting, I suggest you stick with simple, which is either 50i or 60i and have your results transcoded if you must; if you can't justify a conversion then I'd say 60i offers a closer to 'universal' result. Cheers, GB (stuck somewhere between UK & USA) |

I've had no joy getting rid of the banding issue from off frequency fluro lights. They were possibly some really wierd frequency though. I tried all the settings. The flicker filter in the Z1 though worked a treat when I've tried 60i down here and I know it works the other way around. |

Still, writing a NTSC DVD will get you the largest base for playback. Acquiring in NTSC then makes sense to me. George/ |

No, 30p isn't in the BD specs just like 25p, however using 50i templates, I have no problems authoring my 25p stuff (and playing it back on many players, including stand-alones). I don't see a reason why 30p couldn't be burned as 60i, per analogy...
