HD monitoring and the RAID issue
Hey Folks, just looking for a piece of advice here – we’re considering doing color correction and final FX post uprez to HD via a Teranex machine, and we’re looking into the possibility of using an HD monitor with our G5. Now, other than the option of AJA/Kona2 (which is unfortunately out of our budget), how are we going to interface with a monitor? Is it possible to just interface with an HD monitor via the second DVI port on my video card (providing my card has dual monitor support)? Or will I need a specific interface card, and if I do, do you have any suggestions?
Second issue is storage; I’m not even going to go into capture, because I already know what’s best for that – AJA Kona2, which I will be able to have access to for the capture of the footage. Now what I’m capturing TO – that’s an issue. What kind of transfer rate am I going to need for working with HDCAM footage on the G5? Will a FW800 RAID suffice, or will I need to go to SATA2? Am I going to need a big huge RAID 5 array, or can I get away with a couple more LaCie Big Disk Extremes? (an inexpensive RAID 0, with two 250GB drives)
Thanks much for any input, I truly appreciate it.

Um… yeah…
If your going to monitor on a consumer HDTV connected to the mac Via a dvi cable, your color is going to be way off (at lease 50% off). Unless if you use a Pantone Spyder Pro on the HDTV and set the calibration to NTSC. I do not recommend this. And for storage, with HD you need speed much more than space but at 130MB/s for 720p your going to need a lot of space too. HDCAM is NOT like DVCPROHD. The mac can not decode the digital information of HDCAM. You must recapture at uncompressed or some other compression system. If your really thinking of doing HD on anything less than SCSI 320 or FC raids, you’ll have nightmares.
A much better solution is to dub everything to a deck format that you have in your possession, like DV (d25), with timecode. Edit the DV, and then go do an online on a purpose built system that has the drive speed and storage that you need.
This is about baseline for me:

HD and SD On-lines
FCP 5, OS 10.4.2
G5 dual 2.7, 8GB ram, x800xt
Kona 2, aja io full
Medea SCSI 320 5TB Raids -
Wow, thanks for the heads up! I’ve had a hard time finding information on what kind of bandwidth 10 bit uncompressed 1080P @23.98 was going to require… Suffice to say, I’m thinking that my workflow is going to have to adjust around that.
Thanks again,
Kris
