HD Pro Res doesn’t work on G5 Quad.
Well, finally upgraded here today.
And much to my disappointment, The Pro-res codec does not work in HD on the G5 Quad machine for capture.
It drops frames and fails within 4 seconds on my setup here.
Thanks for the forewarning apple!
Just venting…I realize a new mac pro is in order but its a damned disappointemnt that the Quad Core couldn’t at least handle it.

It sounds like the only way around this will be the AJA IO HD, which takes the load off of the CPU and puts it onto internal processors. Though it’s possible that you still might need Intel processors. Anyone find a data sheet on that?

[Lee Berger] ”
What type of media drives are you using?”That actually doesn’t play into the equation with ProRes, that’s a CPU thing. Yes you want fast drives, but even Fibre Channel with the G5 Quad would most likely not work.

[Lee Berger] “What type of media drives are you using? “
that has nothing to do with it ( for once it is not a drive issue)
You need an Intel machine running FCS2 to be able to encode HD files into ProRes
It is a CPU issue and not my normal mantra “if it’s dropping frames it must be the storage ” speech.gary adcock

Did you try the capture via SDI in or component in?
The reason I ask is that I’m currently reading the Apple white paper on ProRes 422, and it does seem to imply that video captured via an SDI input may require fewer and less complex computations. If that’s true, then its possible going SDI might enable one to capture ProRes on the non-Intel lower-end MACs. In any case, its worth a shot…

Ciprico 4210 disk array rated for up to HD 4:4:4 RGB HDCAM-SR or VIPER Filmstream.
More than adequate. 🙂

Interesting that David.
I was capturing over component from my JVC HDV Deck.
I don’t have any SDI HD capable decks yet.

Yep, we all need somebody to test that pronto. Wish I had an HD deck here. Anybody???

David
just tested it with a Kona LHe on a 3Ghz dual and see no difference with the Prores encode.Same source, component vs HDSDI. No difference on the my Leader scopes either.
My guess that is a error in the manual is written since technically there is no analog HD capture on Pro Decks. They say HDCAM is a 4:2:2 codec in the Color setup manual too.
