In the interest of discussing the DVCPROHD codec, I wanted to show everyone a few examples of how amazing the codec can in fact be.
I have a few DVCPROHD 1080p QT single frames from a film that was shot in 24p HDCAM.
The entire nearly 40 hours of footage was captured to a 2 TB RAID through FCP 5 and a Decklink HD card via SDI from a portable HDCAM player-only deck. (ain't that a mouthful!) The card captured the footage flawlessly at 23.98 fps without any pulldown removal. (Decklink recognized the 23.98 frame rate)
These are single still frames of twice compressed HD material (HDCAM 144mbs/DVCPRO 80 mbs, approx). The data rate of the material is 11.4 MBs according to FCP. Unfortunately, you will need the DVCPRO HD components of QT to view these frames. I have converted one of the frames to a Tiff, but it's bothersome because something within QT player adds a little aliasing to the 1920x1080 frame upon export, and I'm not exactly sure why. The actual frame from the codec looks appropriate from within QT as a DVCPRO HD clip. If anyone knows how to properly export this frame without adding artifacts, please let me know.
This is the level of quality that we are working with in order to compress an HD h.264 and WMV trailer.
As those who are able to view the frames can see, DVCPRO HD is pretty phenomenal overall. It is my desire that the HVX will produce 1080 res footage at this level of compression cleanliness. I know there are all sorts of issues with just how much res you get from the CCD and at what level of noisiness (disregarding aesthetic issues of DOF with 1/3 chips amongst other items), but I think Panasonic can do it.
Just wanted to show what can be acquired through SDI in that codec.
