If you record anything that is artificially lit, and you record in NTSC, you willget a “beat pattern” as NTSC and the American HD formats are based on 60Hz electricity, while China uses 50Hz. You see this a lot when someone shoots with an NTSC camera in Europe.
I have been asked a number of times in other forums about “frame averaging” or other effects to get rid of this annoying beat pattern.
Now, if all you are doing is shooting out-of-doors under sunlight, you’re good to go in any format. But something tells me that you won’t be doing that. And that is why I advise you to purchase a PAL camera.
I do realize you want to use it when you get back, but you may be able to either use eBay or some other service to get a lot of your money out of your PAL camera (which may be hard to find in the US) so that you can purchase an NTSC rig for here.
What if there were no hypothetical questions?
