realtime? really?

I don't think it will do it in what FCP states as "Full Quality RT". You'll get a green bar, probably. I can test this at work in an hour or so.

8-bit will give you full RT however.

Most RT is limited to the following three factors.

1. The speed of your computer and the amount of RAM
2. The Speed of your drives
3. The compression and codec you are working in.


When FCP went to the internal/processor based RT extreme engine which placed the processing squarely on the computerss processors instead of off board, third party processing, then these became the mai factors in determining the RT performance. Rarely does it have anything to do with the video card as it is

I think this is a problem with the KONA driver as I know that this problem does not exist when using "other" cards.
I wonder if an upcoming release will ever solve this?

I have always understood this to be a limitation of the KONA driver, as other configs do have RT in 10bit HD.

[lexerton] "will a Kona LHe do realtime 3-way colour correction?
Project is 29.97 1080i 10 bit 4:2:2 Uncompressed"

Are kidding! There's nothing about 10-bit HD that will be real-time. You will have to render before going to tape, no matter what. Kona doesn't accelerate any effects. The only "acceleration" has to do with offloading some of the scaling inherent in various codecs, like DVCProHD or HDV. You are working in the most taxing common video format there is at the moment. Drive performance is also crucial. For example, an Xserve RAID will barely give you the performance you need here.
