RT 3 Way Colour Corrector in HD

[David Battistella]

The card has nothing to do with this. It all depends on your drive speed, computer and RAM.

Actually NO
the color corrector is built into the card and yes you can make realtime CC on they fly even in HD with the exception on 4:4:4 RGB format

thanks for this info! I thought the card was doing som ework….

Is there a list of what RT effects can be used in full resolution in HD on the card??

Kaspar,

Is there daughtercard processing on this card? Can you select the Declink HD to do the FX from within the final Cut Ro effects handling pane? I just don’t see where the cards “extra” processing power is coming from.

I am sorry
I havent cheked how things are done in FCP 5 but int FCP 4.5 yes you could choose blackmagic for effect handeling and yes there are hardware aplications on the card for CC tools

I dont know how the things work under the hood – what I do know is that I have set the effect handeling to FCP all other than BMD 8 bit 2Vuy codec and when I remove the card – no longer are CC tools realtime – not to mention any HD monitoring

I heard the monitoring is now OK on cinemadisplay so only thing we need is someone without the hardware to try uncompressed 8 or 10 bit 1080i/p CC tools and we should have an answer?

[David Battistella] “I just don’t see where the cards “extra” processing power is coming from.”

Now I am really confused. I posted in an earlier thread a question about the diff. regarding RT effects, bet. the HD 4:2:2 (which also handles SD) and the forthcoming Matrox Axio.

The answer was, the Blackmagic card is strictly i/o, all processing for RT effects (dissolves, etc.) is on the CPU.

This thread seems to suggest otherwise…? Or am I reading too much into it?

Actually, the effects are done on the CPU through the Blackmagic driver. Thus, RT Extreme or Blackmagic can be selected as the FX architecture.

On the Decklink HD Pro, however, downconversion is actually done in hardware on the card. I would imagine that upconversion would work the same way one day.

On the Decklink HD, downconversion is performed by the Blackmagic driver on the CPU.

I hope that clears it up.

The main question to ask Apple is “Which built-in FX are 8-bit and which are 10-bit?” I’m dying to know.

Keep in mind that AE Compatible Plug-ins in FCP can only work in 8-Bit RGB. The spec does not allow for YUV processing. It also allows for 16-Bit RGB processing, but FCP doesn’t go beyond 8-Bit RGB.

Thus, I think the future could be found in Motion’s FX plug-in architecture called ‘FxPlug’ that can also enable real time processing. Time will tell.
