Hi,
Since I cannot see your pictures it is really impossible for me to say. Did you buy it from a local dealer and they can help you evaluate it? What are you monitoring it on? Some LCD monitors add noise that folks are attributing to the camera and that isn’t real.
What are your settings in detail and coring? Which gamma are you using?
Best,

Sorry, to my knowledge of the architecture of the camera this could not be added.

Hi Shane,
Normally you are right on the money, but I had to squeak in on this one.you could do DVCPRO50 on FW400 drives. Done it.
How’s the show coming? 🙂

There isn’t a hold up, we are making a lot of cameras, in some cases it is more than 20 per dealer. Take a look around there was a dealer in Washington DC on Monday that had 5 that were not pre-sold. They are gone by now, but take a look at the smaller dealers, may the very one in your back yard.
Best,

Robert is a pretty knowledgeable guy, but I am not going say that is your fix as I have no idea of how to do that. He seems to have run some pretty exhaustive tests, why don’t you ask him.
Best,

[redindian] “Do you mean to say that since its recorded as DVCPROHD it becomes 4:2:2?
Eg: If I shoot with my webcam, play it on TV, and shoot that with 35mm – it does not make the quality of the footage as 35MM.
So if the color is captured at 4:2:0, and thrusted into a 4:2:2 format – where does that unrecorded information come from?”
Actually Redindian if you want to take it to such a ridiculous input, yes it is. It will probably look just as bad as your webcam does but DVCPRO HD is not 4:2:0, or 4: .5 or whatever, it is 4:2:2. It is a SMPTE standard. And frankly the reason that Canon shot their camera demo on the DVCPRO HD format is becaus coming out of the camera it is uncompressed.
The problem here is that nobody wants to understand the engineering behind this. If you want to look at the input to the DVCPRO HD, you back up one step, it is not a web cam. It is the 1080P capture from that previous stage in the system. If you want to see what is the input to the 1080P stage it is not webcam it is the output from the chip set which is an analog output that is generated off of the spatial offset. That spatial offset is 1440 X 810. This is not webcam. It generates some very nice looking pictures.
But to get back to the ridiculous point. Yes, if you fed a garbage picture to a 35mm film would that keep the film from being 35mm. Don’t think so. If you fed the output of the XL-H1 to DVCPRO HD, does that make it 4:2:0, not the standard, 4:2:2 in DVCPRO HD? No, that is why the Canon demo was produced on DVCPRO HD. They know the difference beytween 4:2:2 and 4:2:0. The HVX200 records in DVCPRO HD which is 4:2:2 and DVCPRO50 which is 4:2:2 and DV and DVCPRO which are 4:1:1.
Hope this helps,
Jan

Well my favorite is the EFP-Bag from Kata made by KATA. I think their model is an MC-61 and our. model is the EFP-BAg. I holds the camera and your laptop in the back. Has the ability to take a roller through the back so you can have wheels if you want. Holds tons of stuff.
On the smaller commuter flights I have had to hand carry the camera on the flight and put the bag into the gate check but that has been rare.

Hi Folks,
Gary has been on vacation and I did not have an Apple edit system at home so could not provide an answer. We did ask Apple this morning and this is the answer we received:
“When configured to capture using a non controllable device, FCP does not pull any timecode information from the device. This means that any media captured using capture now will not have any specific timecode recorded, resulting in the clips starting at 00:00:00:00 when used in FCP.”
So there is the answer.
Best,
Jan

[brianluce] “If the HVX won’t do true 4.2.2 in HD mode, how about in dvcpro50 mode? is that true 4.2.2?”
It is true 4:2:2 in HD or DVCPRO 50.
Thanks,
Jan

:Lawrence Marshall–540 vertical pixels also means there are only 540 vertical chroma pixels on a 1080p format.
No Lawrence that is not what that means. Please go back and reread the article. Look at where it talks about pixel shift and how that ups the ante.
>That means color is practically 4:2:0 and not 4:2:2. 4:2:2 was supposed to be an advantage over the competition and it’s not there. The HVX has exactly the vertical chroma a 1080 HDV camera has. And lower recorded horizontal chroma in NTSC HVX. 640 compared to 720.–
You need to look at the part that says that the output of the chip set, which BTW is an analog signal, and pay attention to the part that says it outputs a 60P signal and in a 14Bit A/D converstion to a 19 Bit DSP it is transformed into the digital domain. From there it is recorded in the DVCPRO HD format which indeed is 4:2:2.
>–540 vertical chroma pixels in 1080p format is 4:2:0 color by definition. There is no higher color resolution. The camera is recording 1080 chroma but the sensor only has 540 pixels.–
Again, go back ad read what the article says about the equivalent pixel count after pixel shift.
And:>–Pixelshifting is only reading extra luma by using the sensor offsets. Chroma stays the same. Since we know the native resolution of the sensor now, any output will be limited to 960×540 color.–
Again the signal coming off of the chip is first an analog signal, and then is transfromed into a 1080P/60 signal and from there all other formats are formed.
>I purchased and just received my HVX-200, and wonder what the above translates into “real world” when I go to shoot green screens…
I think you like others that have tried it will be very please at the results. There are numerous examples of this on the dvxuser site and the DVinfo community site as well.
