HD 4:4:4 RGB 10bits with FCP?

[Anonymous]

Hi
I have asked this question many times but i have got no answer. Black Magic has a board that captures HD 10-12bit 444 R

Hi tomas,

The reference on the Apple site is probably regarding what FCP can capute over firewire(negating the need for a third party Video card) If however you add the Blackmagic card to your box then you can indeed capture 4:4:4 rgb at 10 bits from HDcamSR or whatever.

Hi Tomas,
Angus (and the Apple technician are right) FCP, like discreet’s IFF/SF systems, is resolution independant. FCP works with Quicktime files so provided the media is in Quicktime format, FCP can see it.
However, as I understand it, the Black Magic card will create 4:4:4 Quicktime files but it doesn’t offer any additional processing or acceleration so most effects have to be rendered. Maybe someone else can shed some light on this.

Cheers

I can’t remeber the specs of the blackmagic card, but it seems likely that it incorporates some kind of acceleration.

What I know is that the AJA Kona2 card does. It lets you reate 4:4:4 files in FCP and gives you hardware acceleration for them (I think you can edit like 5 channels in real time or something like that). This card comes with its own Quicktime codec to do this. It also gives you SDI in/out so you can capture through it.

thank you all.

I have been trying to get info from apple but the only thing i can find is

Supported formats and I/O*
* Uncompressed 8- and 10-bit HD (4:2:2 YUV) via PCI card
* Uncompressed 8- and 10-bit SD (4:2:2 YUV) via FireWire or a PCI card

I think that if they are able to make 444 rgb via a PCI card they would announce it.
Maybe The board captures 444RGB but the software transforms the data. Apple does not develop PCI capture Boards so i asume they refer to AJA or BlackMagic.

thanks

Hi again tomas,

As was stated above FCP is resolution independant so if your board will capture 4:4:4 RGB media then FCP will work with that. The black magic and Kona cards will give you mint picture quality but you might want to try out a G5 using files of that size before you part with your cash. I’ve never tried it, but I think interactivity might be pretty slow.

Angus, don’t you think that it is a strange thing that apple says 4:2:2 yuv with pci board if they could achieve 444 rgb?

Hi again Tomas,

yes that seems kind of strange right enough. I’m not an FCP user you can get some expert opinion on FCP tech issues over at the creative cow FCP forum.

you can find it at

they should be able to give you the full lowdown there

yes in fact yesterday I was there.

5 streams of 10 bit 4:4:4 ? at 1080? at about 198 mb/sec .. 😯 hmm…

If you manage to get the full 300>400 mb/sec from an xserve thats 2 max..

I belive fcp down rez’s.. and looks ahead.. so you can see real time.. least thats what the demo guy Byron (i think) said it did…

in the end… you still have to render….
