4:2:2 isn't happening on this model. The forthcoming 2/3 camera is the only one that's going to support the higher bit rate.

HD SDI out means at least 4:2:2 with the HD SDI right?

Of course, I'm not going to complain if it happens. ;) |
Wasn't it true that the current XDCAM HD cameras actually down converted to 4:2:0 before the live signal was sent out SDI? I remember at one point there were a lot of threads about this. The signal was still uncompressed but the chroma sampling was reduced for whatever reason. I hope what I remember was just false information at the time.
If it was true however I wonder if SONY would limit the SDI output on this camera the same way. As to the 4:2:2 recording mode... I do think it is something that SONY could decide to do. I mean the media and camera itself could handle it no problem at all. It all comes down to how good they want to make this camera. If SONY is really trying to target this camera at HVX200 users which it pretty much is then it may make sense for them to also have the 4:2:2 mode. This would mean the camera would pretty much kill the HVX200 is almost every single aspect. HD-SDI longer recording times cheaper media. full resoultion 4:2:2 recording 1/2" chips These are all things the HVX200 does not have. If the SONY does not have the 4:2:2 mode then I'm sure there will be debates and heated arguments all over this and other forums about how the HVX200 is still better because it records 4:2:2 color right to the card. Regardless if it is better or not the focus of the argument will be there and many people may be afraid of 4:2:0. Many of us already know 4:2:0 is not bad at all but it is hard to try to convince some people of that. |
Given past experience, I think we can assume that any information as to whether the camera is definitely 4:2:2 or not is unlikely to be reliably accurate... even if apparently from the horses mouth!

Sony often try and protect their higher end gear, but I hope they add 4:2:2 50 Mbit/s to this camera because it wouldn't really affect the sales of the largest, shoulder mount cameras.
It would just make this the best "palmcorder" ever made... on paper at least. It would also make it the weapon of choice for B camera shooting in many circumstances. A nice small shoulder mount version would be good too! Like the HD100 line. |

Actually I was thinking more the people who are new to the game and insist on trusting numbers and specs only.

As for the 50mb 4:2:2, that is a feature of the 2/3 full size camera shown at NAB. It is still my understanding that the forthcoming XDCAM EX camera will not offer that high of a data rate. -gb- |
Ok thanks for the updated info on the XDCAM head. It was actually your posts on the XDCAM forum that mentioned that the head may be 4:2:0. After searching that whole forum no mention was ever made of it actually processing 4:2:2 in the DSP.

Everything I heard initially was that this camera would offer 4:2:0 colorspace with a maximum bit rate of 35mb. This seemed to fit with Sony's current crop of HD stuff, offering a "low end" (cheaper with less quality), a "medium" (higher quality and a bit more cost) and a "high end" (very expensive but with very high quality). This is kind of the model that most video manufacturers use and it would be kind of surprising to see that changed.
However, I have been hearing rumors and hints that there may be more "surprises" in store before the XDCAM EX is released. So who really knows? I will say this, if for some reason Sony DOES put in 50mb 4:2:2 colorpace.....they will have a really hard time keeping this thing in stock anywhere. |
