wow.
so you are getting a new machine?
what success have you had in the past capturing video while running parallels to do other intensive work?
you want the ioHD unless you are moving to an intel. it is the only product with ProRes encoding on board, period.

you obviously have the other card, go ahead, line up 16 streams of HDV and turn on dropped frame notifications. tell me what you see.
i dont think AJA is known for marketspeak.

well, that would be more toward the opinion end of things and not science. i set up a test, put in 16 HDV clips and see which one renders and which one plays back, there is your scientfic answer.

[Graeme Nattress] “AFAIK the BMD cards also do that hardware scaling – they just don’t go on about it or call it acceleration.”
there is hardware acceleration in the kona product and that is unique to the kona product. it taps into the RT extreme architecture and the kona LH applies hardware scaling to the HDV, XDCAM or DVCPRO HD. it does produce realtime as you can play back more than a dozen streams of those formats at once on a dual 2.0 G-5.
FWIW.

i think that sky footage was an early encoding. a few colorists i know had noted it too. i have worked with some similar footage and have seen nothing like that blatant banding that was displayed on the one piece. it surprised me more not many people noticed it!
i’d chalk that up to early tech anomoly or bad footage selection, i dont think it is indicative of what you will see with the shipping product. it certainly isnt what i am seeing.

if you dont see innovation in AJA, that is likely the starting point of deciphering the problem. the outlook is probably not what their OEM business partners see. obviously apple saw it.
sounds like there is a country song just dying to be written on this topic, but i dont think many people on this forum would buy the record.

[walter biscardi] “No because a Kona 2 only runs on the PowerPC G5’s and those don’t support Pro Res capture”
just a quick clarification–G5’s support HD PRO RES 422. now the SD world of ProRes capture off of signal is not yet defined. The Quad G5 will certainly chug through it. (have your Activity Monitor CPU Usage window up and watch it redline!)
but in all reality, i dont believe based on some tests i did that the PCI-X bus systems will do much.
-
Per the apple tech article, you need an Intel MacPro to capture prores 422 HD.
because the Kona 2 operates in only PCI-x bus slots and those systems operate only in dual G5 2.7 or less…um, no. maybe a chance in hell it can downconvert and capture to SD, you will know soon enough when you test it.

OK, i ran some tests on video i shot this weekend. it appears to confirm what gary adcock posted as well as the new apple tech article
https://docs.info.apple.com/article.html?artnum=305582
i have a Quad G5 3.5GB Ram and kona 3/hd10ava with more than capable storage for 2k if needed.
1080i capture to pro res 1080 and pro res 1080 HQ both failed. frame drops were indicated after a few seconds. failure
now, the one thing i did to get it to work was to cross convert the 1080i to 720p in the kona 3 capture card. i captured 720p (not HQ) and it worked fine with no dropped frames.
so hey, i can capture 720p fine!

excellent, we will all be guided by the “Yoda of Framerates”. i dont know how many funky issues i’d be having without your K-nowledge.
welcome.
