Does FCP degrade 10 bit files/clips?

[David Smith] “I’ve head Macs can’t handle 10 bit. “
They can’t out the graphics card (the Quadro 4000 for example).
FCP and a proper signal path is most definitely 10 bit.
[David Smith] “NEC PA241w – which I’m going to have to take their word for it is 10 bit. “
I wouldn’t. In order for it to be 10bit, it has to be a 10bit capable panel, not just process in 10b.
If we were in the same room I could show you this in about 3.5 seconds.

“If we were in the same room I could show you this in about 3.5 seconds”
Could you explain how to check in 35 words? 😛
Are you saying that there is no way to see a 10 bit image? If a Mac won’t output 10 bit than what computer system does?

[David Smith] “I’ve head Macs can’t handle 10 bit. I’m setting up my system right now. What I don’t understand is: If a Mac Pro is not 10 bit what are people using to color grade 10 on? “
Is nothing about Macs, is about your cards and monitors.
You need and external video card 10b capable and a 10b or CRT monitor.[Jeremy Garchow] “I will disagree with Rafael in that when rendered, the gradient is indeed 10bit. “
So what do you expect from an 8b Ramp when you render it (blur) at 32bFP and export in 1n 10bYUV?
To tell the difference between 8 and 10b just need FC’s scope.

David-
There’s a difference in the graphics card (sometimes referred to asthe video card) that drives your OS display montitors, and a video capture/output device such as a Kona, Blackmagic, what have you.
The graphics card can only display 8 bit. The Kona et al is 10bit (or more) capable. The two are mutually exclusive. You cannot judge the quality on your computer display monitors, but rather you need to use the 10b display path that is available via your Blackmagic card. I looked up that NEC monitor, at first blush, it does appear to be 10b capable.
Rafael-
I dont understand what you are saying, there is no blur necessary. The generators in FCP7 are generators, meaning they will generate at whatever bit depth the timeline is set to and rendered. I don’t know why you never believe me on these points. You seem to think FCP7 is stuck on 8b RGB when it’s not. Some of it is (in RGB rendering, and RT previews) but most of it is not.
I dont know whats happening if you use FCPx which is what you seem to be doing. There is no video out of fcpx yet.
It’s really really easy. Make a 10bit timeline, add the gradient generator, render. That’s all you need for a 10bit gradient. Do you have a 10bit signal path Rafael? Meaning do you have a monitor that can display this properly?

[David Smith] “For that monitor I’m not connected DVI I’m connected SDI > Blackmagic HDLink (which they claim is 10 bit) > Display Port. “
I am unfamiliar with the HD Link, but i know in the similar AJA device (HDP2, which I have and use daily) you specifically have to select “Deep Color”, which in HDMI terms is 10 bit (or sometimes referred to as 30bit) color. It is hard to know if that NEC monitor accepts 10bit over display port, it should, but you never know. When you get in to monitors like these, corners can be cut to save costs, even though the specs are inflated. You would have to test and see.

[Jeremy Garchow] “The generators in FCP7 are generators, meaning they will generate at whatever bit depth the timeline is set to and rendered.”
That’s absolutely wrong.Can you tell me any Graphic application working in YUV?
FCP graphics are generated in 8b RGB, then are converted to the Color Space and bit-deapth of the sequence.
Whatever those setting what you get is converted 8bRGB.[Jeremy Garchow] ” I don’t know why you never believe me on these points. You seem to think FCP7 is stuck on 8b RGB when it’s not. Some of it is (in RGB rendering, and RT previews) but most of it is not.”
This is boring Jeremy.This has been discussed thousand time.FC can’t render but 8b when in RGB.
10b RGB stuff will be converted and rendered in10b YUV; then the 10b YUV converted again to 10bRGB on exporting.You can preserve the 10b, but you can’t keep all the pipeline RGB.
The only problem is letting FC to do that conversion.
Cineform, GlueTools, etc, use their own engine, as the guy of Cineform (Michael Newman) explained here.

There you go again talking about RGB. We aren’t working in RGB here. We are talking about a10b YUV setting.
No, no other graphics programs work in YUV that I know of. Fcp does.
I would ask you to prove anything that you just said (save the 10b RGB, but that is irrelevant to this discussion).
The generators generate at float, but are temporarily displayed at 8b when unrendered. I’ll ask again, do you have a 10b monitor?
All processing is done at float, then compressed to sequence settings.

Rafael, how do you access those scopes you posted in the screen shot?
Jeremy, The HDP2 you mentioned. Does it work with Blackmagic stuff? Like the decklink and Resolve? Also does it have SDI to Display Port ability?
Also, does it get really hot when working? I just bought the HDLink a few days ago and it worked day 1 with FCP, but no more. It does work with Resolve still. It might be a faulty one and I was thinking of trying a different brand.

[David Smith] “Rafael, how do you access those scopes you posted in the screen shot”
The ramp is from AE and generated in 8b and 10b Unc.
The shots are from FCPX wonderful scope.

It’s SDI in (which can come from anywhere) and changes it to DVI or HDMI 1.3a. No display port.
[David Smith] “Also, does it get really hot when working? “
It’s not hot, a little warm, but not hot.
