Will Panasonic have a solution for the noise
I hate to beat the proverbial dead horse, but with so many owners (seasoned pros, I might add) having problems with the unusual noise and artifacts the camera displays, is Panasonic planning to address these issues?
I realize the camera is only a low-level 1/3″ $6,000 camera. No one’s expecting Cinealta performance from this cam (we’re certainly not getting the resolution, which is to be expected.) As someone who works with the camera (and noise/artifact issues) on a daily basis and went out on a limb to get suggest this camera for my dept. it would sure be nice to hear from the manufacturer whether or not they consider this problem a defect and if so, if they are planning a fix.
If it’s not difficult, why do it?

Hi,
There is not a defect in the camera. When we set up this camera we based its look on a very popular look from our DVX100 lineup. If you are coming from a background of another DV camera you may not be familiar with that very popular look of the DVX, which I can only express as an organic feel to it. You can go into the menus and reduce that look by either going to the Black Bress Gamma, putting in more coring and reducing the detail.
When you compare this cameras to other small HD cameras like the Canon and the JVC you will find that it compares favorably.
Hope that helps,
Jan

I have to agree with Jan here.I’ve heard lots of people on the other forum that complain about the noise say they don’t expect cine alta performance at this price point.. I think they kind of do expect it. Most comparisons show that all the 1/3″ cameras actually come much closer in image quality to 2/3″ cameras than anyone anticipated. I don’t find the noise objectionable because the overall picture is outstanding.. like 16mm. I wish it was a little better in low light but all in all a fantastic camera and P2 is like having free film !

Question for you Jan:
I was at Res Fest and the image there was extremely clean with no noise issues. The rep there said it was a Rev. 2 camera. I go to DV Expo where there are Rev 4 cameras with considerable amounts of noise. Based on this, it tells me that a Rev via firmware update in the future can clean up this noise as was in the Revision 2 camera? Or is this false hope? Thanks for your honest answer.

Hi,
Since I was there with the camera at Res Fest, the cameras that I am seeing coming off the production line look just like that one. The samples that we had around the sales floor at DV Expo, were also very close, some were noisier as they had less than ideal situations to be pointed at. Light is an important issue with this camera as it is with all of the small HD cameras. There is no problem with the current camera.It has been my experience that people want 2/3″ performance off of this 1/3″ imager and that just is not possible. Laws of physics cannot be denied. This camera looks very good next to other cameras of its price range.
Best,
Jan

Based on the original DVX100 to the 100a and now the 100b, the noise has been considerably better on each upgrade. Will this also be the case w/ the HVX or can noise be reduced w/ firmware updates?

Jan,
the problem isn’t noise, it’s the “banding blocking” you’ll get with most of the settings in the darker areas of the picture. Block size is 8×8 pixels. There was very clear test made by Saru and lots of discussion in dvxuser about that.Do you have a comment on “banding blocks” or should we just glue our gamma setting to cine-d?

Actually Joselyn the difference between the DVX cameras and the HVX is night and day, ie the size of the pixels and the size of the signal. You should compare the HVX with the other HD cameras below $10,000 and you will see what I mean.
Best,

Jan,
can you tell what is the pixel size of dvx’s ccd?
Same here in Europe? -
understood jan. but can noise be reduced w/ possible firmware updates?

Hi Joselyn,
The AG-DVX100 is internally a completely different camera than the DVX100A. The DSP in the A version and the new chip set made it have a different noise structure than the DVX100. There was no possible upgrade to make a 100 into a 100A. The DVX100B, again is a completely different camera with again a bunch of new internal processes and parts. No software or firmware upgrade could make one into another.
The AG-HVX200 is not a noisy camera. It has a noise level that is to be expected from a 1/3″ HD imager. In fact it is quieter than most of its competition. Point is that even though you saw a difference in the three DVX cameras, none of them could be software upgraded to a different version. I fully expect the same to be true here as well.
The HVX200 is a wonderful little camera, it just isn’t a $60,000 Varicam with a 2/3″ imager. Laws of physics cannot be denied.
Best regards,
Jan
