What kind of computer components do I need / what kind of configuration, to take uncompressed HD output of the Sony camera and feed it into a computer.

I want the cheapest setup. Xbox is too expensive.

How much would it cost me? I want to use the same coputer to capture and to edit with.

Is there any laptop I could use?

How many MB do you need for 1 minute in high quality Prospect HD mode?

What's the best deal on Prospect HD?

I assume you mean BOXX is too expensive because Xbox is cheap (although under powered for this application.) :) For any real-time capture apps you will need a decent dual Opteron system which can be purchased for aound $4k. Prospect HD + HDSDI hardware + all supporting software is $6K. So a complete 10bit real-time HD editing system can be built for $10k.

David,

Thank you very much. I did mean Boxx. Let's say someone would fit on Sony HDV camera decent lens, with no color fringing, like Italian guy did, and then recorded 10 bit Cineform codec; how would quality compare to 8 bit compressed 1080p Cine Alta, after highest quality deinterlacing from 1080/50i? How would it compare to original HDV codec? How would it compare to Sony F950?

Does anyone have any thaughts? I know that bigger chips will have better low light performance, etc.; I just want to know how would it look on large theater screen, after film out, if it was shot with plenty light.

10bit CineForm will easily outperform 8bit HDCAM so the quality would be very good, yet your camerra modifications will still most likey fall short of Cine Alta. Plus deinterlacing can never match the resolution of native progressive. All that said, the film out would still look very good.

David,

Thank you. So far reports were film out with the HDV codec looks excellent, that at 1080i, when viewed on top Sony HD monitor it is hard to tell which shots were taken with Z1, which ones F730 HDCAM.

So if we fit beteer lens on Z1 and record with Cineform 10 bit codec, we should maybe have similar type of quality comparison to 25p HDCAM.

Z1 looks nearly as good as 1080p F730. Getting rid of HDV and using better lens and best deinterlacer, we may have a quality that will be close to CineAlta, although not as high.

Is it like it?

It may well look quite nice, but there are still big diff's.
1/3" CCD compared to 2/3". Much better true HD lens. 960x1080 pixel shifted interlaced vs. progressive true 1080p.
