4.2.2 video 1/3 inch ccds HDV Spring 2008

I have just seen this on anothe HDV forum.

Anybody have anymore information?

"I think we will see a MUCH better HDV experience with the new announced 1/3" models. They have a completely new signal processing unit which works in 4:2:2. Whatever compression type you use, the results will be superb if a clean signal is thrown at it. This is especially true with MPEG 2 = HDV. I am absolutely sure that spring 2008 will be the time for massive jaw dropping."

The title is an oxymoron and the post you're referencing was probably written by one. HDV is NOT 4.2.2, by definition.
MPEG-2 can be 4:2:2, Vegas supports it, well the MC encoder does via the High Profile, in fact mpeg-2 is speced even higher via the Studio Profile.

For what it's worth trying to squeeze 4:2:2 in a HD stream at 25Mb/sec would almost certainly produce some damn ugly images, might be OK if nothing moved I guess. There's a new XDCAM camera that does 4:2:2 at 50Mb/sec but XDCAM is not HDV, not by a long stretch.

can we see a link, so far all I've heard about was the new XDCAM HD 4:2:2 announcment and that's in the middle range of prices and up (15K+ I can pretty safely estimate), and as far as I know the HDV Spec is not even able to do that unless they change it.

As far as 1/3" imagers, that's no big deal, they already are 1/3" in pretty much every case out there on a prosumer and above level.

I think what Lingo is referring to is internal processing at 4:2:2 with a 4:2:0 output, which is what the current crop of HDV camcorders do anyway, but someone has taken that as being a 4:2:2 output vs internal processing to the DSP or output over HDMI or analog.

Thanks for the clarification Spot I am sure you are right.

Sounds like a conflation of the camera sensor processing vs. the recording medium plus the new 1/3 inch CMOS sensors Sony recently announced for their latest, as yet unreleased HDV cams.

=========
Sony HVR-V1U and Sony HDR-FX7 have three 1/4" CMOS sensors.
So does the Canon GL2 to name a few.
