i don’t know if pci-x is necessarily going away. there could be pci-x and pci express in the same system. pci-express has far more benefits to storage and video cards than it does for well built capture card…the kona 2 pci-x can operate in the 100 mhz pci-x slot and deliver dual link HD today…
it very well could be “transitional pci express boards” that include both pci-express and pci-x on the same motherboard.
if you need to do more than 4:4:4 10 bit uncompressed 1080 dual link, then wait on pins and needles until apple announces whatever it did not announce today (or at siggraph, or at IBC…). otherwise, i don’t see what pci express is offering specific to editing.
open GL and storage are other matters…

i’d guess it would be more related to an apple announcement of the existance of PCI-express. anyone remember ATI’s thermal freeze a few years back?

i’d wait for the 500GB seagate myself, i think that should prove better for a myriad of reasons i could extrapolate on when it ships…but mostly on finer points…if you are putting something together in large part because of low cost, hitachi is not too bad.

so what do you do with sata when you need raid protection or to expand? Fibre! Fibre! Fibre! 4Gb Fibre!

for DVCPRO HD and SD uncompressed 8 bit, your overhead is about 20MB/sec and i use both the superbigdisk and the g-raid. works great for one stream or so…as you fill these raid drives up, they get slow, so what you see in the first 20% of capacity is nothing like the slowdown you see at 80% capacity.
720 8 bit uncompressed is 110 mb/second which is fairly impossible with a fw 800 raid.

i just played with a kona LH today at a local reseller and tested a myriad of formats. it is very similar to the kona 2, except no upconvert and 4:4:4, less AES audio channels–but it is a kona, that is for sure! accelerated compressed HD formats….hardware downconverter, nice breakoutbox…
it was tested with a 2.7, huge 4Gb array and atto 4Gb card…

your problem is really the slow bus on the 1.8 G5, not the processor or videocard. if it were to install (runs a checker), you could basically never do uncompressed HD capture or even playback from your storage…limitations like that. doing SD and compressed stuff, you can likely get away with…the issue is your storage of choice working with that system…the problem is the dual 1.8 is not a good HD choice

it is pretty simple actually. if you are doing post, compositing, mixing other footage in, keying, color correcting, effects–go dvcprohd. if you are just doing straight cuts, you can have fun with HDV and money to spare. also, who are you selling this to? do they even consider HDV to be HD?

um, yeah, i will take that bet for the following reasons:
AJA was the first FCP card on OS X.
fcp is doing better than anyone could have envisioned and AJA is the only FCP development partner in the card business
their engineering is awesome-10.3.9 supported, 10.4, 10.4.1, 10.4.2, and fcp 4.5HD/fcp 5 from the same driver.
pinnacle developed their stuff for os 9, had various issues brining it to os x, and simply made more money selling pc versions of their stuff for $500 rather than patching up older targa boards to work with newer and newer technologies.
come on in, the water in warm!

i would guess you can be dismissive of HDV if you already own a $90,000 avid system and set clients. i would suspect that FCP is already winning those interested in HDV with their native support. If you put a dollar figure on the Avid solution versus the FCP solution, you will find quite a difference–enough to purchase a high speed SAN for starters. Can Avid Adrenaline do uncompressed HD yet?
i just think it is too sweet the way FCP supports most any major camera native format and not have to drag things to proprietary codecs to get “real time”.
