Thanks for your answers.

I have some questions about the 4:2:2 feed.

It seems the processing power is needed to convert the raw stream into a compressed, easier to edit stream.

Would it be less taxing to actually capture the raw stream and compress it after the fact, not in realtime?

Or would the raw 4:2:2 files be huge and take up too much space?

Thanks

There is this trade-off of sorts that occurs between the two extremes. When you have uncompressed material, you need a wider I/O pipeline and more storage than you do CPU performance. When you work with highly compressed material, the opposite is true...more taxing on CPU, less I/O bandwidth and storage size.

With hard drive prices getting so cheap these days, I see no reason not to build a RAID set up and then you are looking at about $1000 for a decent capture card. Working with uncompressed helps maintain image integrity throughout the post process also.

Another option would be to use Cineform Prospect HD.

www.cineform.com

You can capture on a single drive without much trouble. It's a pretty good way to edit, especially for Premiere Pro users. I do believe they have other solutions for other NLE systems.

So in order to make best use of the EX I'd have to:

Get CS3 and Prospect 2K for my Dell M90 (that has 4g ram) to get decent results editing HD.

I want to get this right as mistakes will be costly.
Think I may hold off on CS3 for the moment to see how soon they bring out support for the camera directly.

Thanks for the responses o this thread.

4:2:2 SDI sounds great, but seems like it is pretty intensive to get running.

So it looks like to aquire from the SDI port there are two ways to go:

Flash DXR - no computer needed, records on to CF cards, $5,000

Tether to a computer - needs a hardware card, software to go with the hardware card, and a computer.


Is there a piece of hardware that interfaces with a laptop for the second solution?

Thanks

Aidan,

You should only need Prospect HD, not the 2K version.
Also, Prospect HD should be backward-compatible with PPro 2 as I downloaded the trial version with only PP2 installed, and it worked.

Another option would be to use the Black Magic Intensity Pro card along with Black Magic HD Link and a box like this: http://www.dvinfo.net/conf/showthrea...ight=Intensity

Or you could use the same box with a Black Magic DeckLink HD Extreme.

This solution along with Cineform should work fairly well.
