No, the PAL version will offer 1080/25p. And yes it is confirmed from the New Zealand rep that the European/Australian/NZ version will indeed offer 1080/25p.
Whether it offers 720/24p is still an unknown; we do know it will offer 720/25p but as to whether 720/24p is offered as one of the variable frame rates is not confirmed yet.

Why would you need to output to tape? You’d only send it to tape if the intended recipient also had a DVCPRO-HD deck. You could just as easily burn the project to a DVD (if under 5 minutes) or to a Dual-Layer DVD (if under 9 minutes) or copy it to a hard disk and distribute that, or render it as a WMV9 file, or many other ways.
Do you have a specific company you plan on distributing the program to, and do you know for a fact they have a DVCPRO-HD deck in-house? If not, tape becomes irrelevant.
If they *do* require a DVCPRO-HD tape, you could perhaps arrange for a rental or dub facility to make the tape for you.

One of my favorite links on the web.
Yes, if anyone is planning to spend thousands of dollars on a web transaction, you might be very interested in seeing the “places of business” that these shops operate out of. Might make you think twice.

Backing up data to DV tape is, with all due respect, a terrible idea. It is neither practical, nor fast, nor cheap.
DV tape is designed to store video data. The error correction involved is designed to trap and correct video errors. If a dropout occurs on the tape, error correction in the firewire signal will try to mask it. That will lead to a complete *corruption* of the data! It works okay with video because we’re expecting to see the video displayed as video, and a little block of garbage in one frame out of 30 doesn’t seem like a big deal. In data backup, it’s disastrous.
Read Coolatoola’s description, and you’ll see that they pretty much recommend that you have to store two copies of your data on a tape in order to have any hope that it’s actually backed up. That means you get, at max, about 5 gb of data.
Run the math: 5gb, for $5, which takes an hour to back up.
VS.
A 50-cent DVD-R, which stores 4.7gb, and can be burnt in about 5 minutes.
DVDs are a vastly better backup medium than trying to use a DV camera as a data tape drive.
If you want to back up to tape, use a drive that’s designed for backing up data, like a DLT or SAIT or something. You’ll be infinitely happier with a properly-engineered solution.
But if you’re just looking for a cheap and easy way to back up 5gb at a time, forget DV tape. DVD-r’s are 1/10 the cost and 10 times as fast.

I’m seeing this false rumor all over the web. For the fourth time today, let me try to put this false rumor to rest.
The camera unquestionably, without a doubt, definitely, absolutely DOES shoot 1080/24p and 1080/30p. I really don’t know how anyone can be confused on this. Look at Panasonic’s website for it here:
https://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?displayTab=O&storeId=11201&catalogId=13051&itemId=93120&catGroupId=14571&modelNo=AG-HVX200&surfModel=AG-HVX200Or, look at the new 12-page brochure — you’ll see on page 12 that the shooting modes are clearly listed.
Or, just listen to Jan, who is the product line manager for the camera and is the single most authoritative voice. Nobody knows more about the HVX than Jan does. And she says: YES 1080/24p, and YES 1080/30p.
Hopefully we won’t have to see this “no 1080p?” rumor repeated again.

If you want a warranty, do *NOT* buy from Broadway! Broadway is not an authorized reseller, they do not carry Panasonic USA product (they only carry gray-market imports). If you buy from an authorized dealer you get a warranty, the DVX Book/DVD, the $300 rebate, the CGR-D54 battery, and a box of the new AMQ tapes, all for free. If you buy from a gray-marketer you get NONE of that stuff. Instead you’ll get a Japanese or Canadian camera, one that has no warranty at all in the USA. You’ll have to send it back to Japan (or Canada) for warranty work.

Blub, I don’t follow your argument at all. Nobody’s talking about focal planes here. We’re talking about the ability of a lens to resolve an image sharply enough that it delivers adequate resolution to the chip.
Standard-def video lenses are typically engineered to provide 30 to 40 line-pairs per millimeter. That’s more than enough to resolve a standard-def image on a 2/3″ chip.
High-def video lenses are typically engineered to resolve much more detail (which is why they cost 10x to 50x more!) High-def lenses typically can resolve around 85 line-pairs per millimeter, which is enough for a 2/3″ high-def chipset such as the CineAlta or Varicam.
These new 1/3″ cameras have the same # of pixels on them, but in 1/6 the physical space! Meaning, they need a lens sharp enough to resolve between 133 line-pairs per millimeter (for 720p) and 200 (yes, 200!) line-pairs per millimeter, to adequately resolve a 1080-line image on a 1/3″ chip.
Think about it — a 1/3″ chip is about 2.95mm in height. 1080 lines in 2.95mm = 366 lines per millimeter, or about 183 line-pairs per millimeter. That means that, to resolve a comparable level of sharpness, you need a lens that can resolve twice as much resolution per millimeter as a typical high-def lens, such as would be used on a VariCam or CineAlta.
That is no small feat.
And that’s why Graeme and I tend to believe that these little chips are pushing the limits of what we can expect in the way of high-def, and that their ultimate resolution will probably be more limited by the lens than by the chips themselves.

At DV Expo East they mentioned an anticipated timeframe of November/December.

The VariCam doesn’t support 1080 at all, it’s 720p-only.
As for frame rates, the VariCam can record at any frame rate from 4 to 60 frames per second. Any frame rate other than 60 will have some duplicate frames added (and flagged) to “pad” the data stream up to 60, because that’s what the tape needs to receive in order to be able to record it.
The VariCam offers frame rates of 4, 5, 6, 7, … 58, 59, 60 frames per second. Any frame rate from 4 to 60. And you can change the frame rate during a shot, so you can do speed-ramping and things like that.

All i-frame compression schemes always compress whatever’s in its frame. There is never a savings on duplicate fields/frames when you’re working with a frame-based compression system.
