Capturing 4:4:4 RGB 10 Bit: Any Troubles with FCP 6.0.1?

[Matt Devino]

Works fine for me with a Decklink card and Xserve. FCP6 doesn’t have any problems, I actually think it’s more stable than 5 in this format.

I agree – we’ve not had any troubles here in FCP 6. The only times I’ve had trouble capturing was when the disks started filling up (oh and the several hours of cursing and screaming trying to get the damn thing setup in the first place).

[Kevin Monahan] “Hi Guys,
I am having trouble capturing 4:4:4 RGB 10 Bit with my Kona 3 and Terrablock setup. I am pushing well over 300 MB/sec and I am experiencing dropped frames. Has anyone captured this format with FCP 6, or should I downgrade to 5.1.4 which is the version that has worked for me before?”

NOT ENOUGH INFO…..

and you know better dude.

Just upgraded to 7.3.1 and driver 5 for kona 3, I was finally able to play back my 10bit RGB 444 project and was thinking that finally all was well again when I noticed that my clips were being compressed in the black gamma range.

Check it out, take bars with pluge or a grayscale and put in on the timeline and look at the black gamma area from 0 all the way up to 50 and you’ll notice on the external HDSDI scope what I’m talking about.

I discovered this while I was doing round trips from Color trying to see if there were any shifts, there actually still are shifts but very border line, a purist might be right to refuse to use it and rightly so but it’s so awfully close that I’m tempted. It was during these looks that I discovered the problem with RGB.

When looking at bars with pluge the pluge above the 0 and below the 0 are gone, compressed and clipped, which means I still can’t finish my online for this particular project, as my deadline nears I must decide to finish in 422 and gluetools myself up to dpx for a film out.

Too bad FCP is still not ready for the silver screen with any sort of accuracy or integrity.
