[Cinemacell] “Does the HVX option too shoot for 1080i/24PA mean that it shoots 1080/60i then converts it on the fly to 1080/24p (full frames progressive) before it records to tape?
No, the 24PA in 1080i mode on the HVX works exactly as it does on the DVX for DV.
The camera shoots 24 frames per second, and then adds a pulldown before recording it to tape.
Since 1080 DVCPROHD is interlaced only, this is the only way to carry a progressive stream in the codec.
Just like on the DVX, where the camera shoots 24 frames per second, but records it into an interlaced 29.97 sec codec.This is NOTHING like doing a conversion in software.
You are getting 24 true progressive frames per second, not taking 30 frames per second and trying to retime it.Does that make sense?

[Blub] “So much for respecting our intelligence!
I smell a rat. Put another way, I think you have been encouraged to take the information away for who knows what reason.
Let the information flow, we will get it eventually, why not here, why not now?
Chris”
You can’t be serious?
Chris – I do respect your intelligence, but it’s more important to me not to spread misinformation.
The charts we shot could easily be misconstrued, and I don’t want that.
No conspiracy here.Barry Green put together a great 4way camera test yesterday (Sony, Panasonic, Canon, JVC).
He should have some results up soon enough.Luis Caffesse

[Ron Shook] “Perhaps Panasonic simply wants you to judge from the picture not the specs, by refusing to divulge them”
I agree Ron, that’s clearly the strategy here (much like Canon did with the XL1 back in the day).
You can’t help but question it though, seeing as every single other camera that Panasonic sells has the pixel count right there on the spec sheet. I’d be curious to see if this is going to be become a standard for the company as a whole or if it’s just something they decided to do with the HVX.
Interesting marketing choice I suppose.

I saw a pretty significant difference between the 1080 and 720 modes.
That was the main thing I was looking for.It seems clear that the 1080 image is higher resolution, not simply more pixel shifting.
I will say though that the 720 footage I’ve shot so far seems cleaner than the 1080 footage.
Not by much, but the noise is more noticeable in 1080 than 720.Keep in mind, that’s when I’m LOOKING for noise.
I don’t want anyone to think that the noise in 1080 is bad, or unusable…
Far from it.Luis Caffesse

Unfortunately, after only a few minutes I had to pull the charts offline.
It seems people couldn’t view the charts for what they were, and I’m afraid that many will pull inaccurate numbers from these charts even after I’ve stressed that they should only be used as means of comparisson between the different formats.
The charts are not accurate and numbers can’t be pulled from them.
The last thing I want is to be seen as a source of misinformation or bias – so I’ve decided to pull the charts offline.Sorry about that.

[David Saraceno] “When I and others eventually can report objectively on quality, that’s all that matters to me.”
I just wanted to add that I agree, that’s also all that matters to me.
I can tell you from the footage I was able to shoot with the HVX I was really impressed.
It’s a solid camera with a beautiful image.Luis Caffesse

Sorry David, maybe I didn’t make myself clear.
I didn’t mean that the details of the CCD chips mattered – or that there was some ‘ccd spec cuttoff’ that would make a camera professional or non-professional. All I meant was that it’s strange not to release the full specs on a professional camera, seeing as most professionals should probably be well informed enough to know how to digest that information.I just think that if we are really in a ‘professional’ realm then it should be up to the buyer to decide what specs matter to them, seeing as theoretically we are talking about serious buyers who are making educated purchase decisions – not just people looking for a simple camera to shoot home movies with.

[Noah Kadner] “Yep- couldn’t even begin to tell you how a Prius’ engine works but they sure are fun to drive and get great gas mileage.”
I’ll agree that the native pixel resolution doesn’t really make a big impact – but I do think the car analogy holds.
The HVX isn’t “the Prius” of videocameras.
Panasonic is trying to push this as a ‘professional’ camera.A car at the same level wouldn’t be seen as a ‘consumer’ car, would it?
It makes sense to keep the CCD specs out of consumer gear – I mean a guy shooting his kids birthday party probably doesn’t even know what the CCD specs mean anyhow. But if you’re selling to ‘professionals’ it seems like a strange move not to give all the information about what the camera is doing.Like I said, I don’t think it makes a big difference.
But personally I think it should be up to the buyer to decide what specs are important to them.Much like Canon and their 24F secrecy.

[Bettsy] “One question. You say you’ve shot on Varicam. How does the mosquito noise in the shadows compare to one? I know the image won’t be anywhere near as sharp but just curious about the shadows….”
To be honest, I don’t think it would be fair for me to make too much of a comparison.
I had the HVX for about 3 hours, and was pretty limited in what we could do with it.
It was nighttime, and we were in an underlit house.I’m very familiar with how the DVX would react to such an environment, but everytime I’ve shot with the Varicam it’s been on large controlled shoots, usually in a studio (so lighting was never much of an issue).
So, I won’t stretch myself to make those comparisons – I don’t want to start any rumors about how the HVX would do against a Varicam. People will take a statement like that and run with it.

If you’re asking how the DV recording on the HVX matches up against other cameras, you should probably expect the DV25 recording to look pretty much like the footage you’d get from the DVX100B.
Of course the HVX can also shot to P2 cards in 1080P, 1080i, and 720P in variable frame rates.
So it’s got a lot of advantages.
