Chips are analogue devices. They don’t have bits.

My best guess is that it is nothing to do with shutter speed, but that the footage is upper field and the filter defaults to lower field. I think when you change that, things will look better. Failing that, arrange to send me the footage to look at and I’ll sort it out for you.

Remember 24pA allows you extract the frames without decompressing the DV and hence preserving the quality. 24p Normal does not allow that. Yet still Sony don’t understand 24p…..

1280×720 is the current “best guess”, but as no details have been revealed, it’s just a guess. All we were told at NAB is that Panasonic are optimizing for dynamic range, resolution and low noise, and that they’d give us the best on all three (or words to that effect.)

It’s got nothing to do with electricity these days. I have a multi-standard PAL /NTSC TV running on 60hz mains. That was an issue in the dim dark past, but not today. The only thing that stops it now is archive material.

Sure it’ll be 10bit if they employ 10bit A to D converters, although it will be noise limited by the D to A converter and other circuitry, so although it may well carry 10bits, there could be 2 or more bits of noise in there…..

Glad to know I’m on the right track and not going gaga.
I really appreciated your comments that you’re going to go for good dynamic range, resolution and low noise on the sensors. Normally people just pick one. I am looking forwards to learning how you’ve managed to optimize all three.

It might be a good time, but it’s not going to happen. Europe and PAL land may say to the USA that they’ve botched their introduction of HD, and that they should adopt the superior European format. With the intro of HD, remember, the USA could have gone from 29.97fps back to 30fps if they’d wanted, just like Japan sensibly ditched 7.5IRE setup in the 80s.
But basically, the archive programming argument is the big one. And that’s going to mean that HD in PAL land is 50hz based.

I agree that an international model, if possible would be best. These days, especially with HD, I don’t see a need for models that don’t handle all possible international frame rates.
However, I doubt that Europe, and 50hz countries in general would adopt NTSC frame rates. NTSC is less used than PAL around the world, so, indeed, if there was to be any change, it should be NTSC that adopts PAL frame rates. One reason why nobody in PAL-land would adopt NTSC is because the fractional 29.978fps frame rate and all the daftness with drop-frame and non-drop frame is something that is laughed at, as is 7.5IRE analogue setup. Sure broadcasters can standards convert, but it should be the NTSC broadcasters who fit themselves in with the rest of the world, not the other way around.
or…
what is likely to happen is that NTSC stays as is, as does PAL, and neither accomodate the other in any real way.
As for arguing – lets keep discussions to facts, not people, and lets always agree that although you might not agree with someone’s facts or their interpretation of facts, or conclusions based upon them, that they are to be respected and discussed in a friendly manner.

Does the box that converts firewire HDV to HD SDI only work with one format, all or some?? I think what you are saying Barry, is that HDV has more than one nail in it’s coffin. For that degree of incompatibility under the “same” video format name to be allowed is ludicrous! How is any consumer going to navigate that minefield??
