Thanks Douglas ! Do you think capturing uncompressed 1920x1080 this way could compete with HDCAM, if we use a 35mm adapter for a better dof ?

In terms of the stream, yes, because it's effectively the same information. In terms of quality, no, because you're still working with 2/3" sensors vs 1/4" sensors, and the relative difference in glass is significant. You can't buy any kind of HD lens for a 2/3" camera even in a used format (that I've ever heard of) for the approximate cost of a new V1 or Z1. Quality HD glass is very expensive, which is why for example, you'd pay around 5k for a JVC HDV body, and 12K for a lens. At that point, might as well step up to XDCAM HD, as you'd get good glass and a 1/2" imager.
As you start looking at uncompressed capture and get all excited about what it *could* do, bear in mind that we've been able to capture 4:2:2 uncompressed out of virtually any DVcamcorder for years, converting to SDI, and bringing it into the NLE as 8 or 10bit 4:2:2 SD. Why haven't more people been doing it?
Cost.
By the time you configure a fast RAID 0, have a system capable of processing the data, etc, you're easily double or more the cost of the camcorder. That *must* be part of your system cost consideration. So, 5K cam, 10K RAID/'puter, etc, might as well be looking at a lesser computer, smaller RAID (if any RAID at all) and XDCAM HD at that point. Certainly worth considering, given the quality difference.

Yes... I don't know if using a 35mm adapter will "override" the limitations of 1/4" sensors. Capturing via HD-SI is still very expensive, far less with this Intensity card. Sure Raid systems are still very costy... maybe by using the appropriate codec we talked about... it's worth a try, at least !

Thanks Douglas (for your V1 samples too !)
