LHi & DreamColor

[Gary Adcock]

[Jim Curtis] “All the problems I reported here seem to have been fixed at this point. I’m getting smooth playback from my 1080i material, and viewing in 709. So, no need for the Gefen box with this footage. I’m not planning on using the DreamColor for NTSC, so I wouldn’t need the box for that. “

Jim,

Glad my setting advice worked for you too. I ran into this issue prior to NAB and never got around to sharing it.

Hi Jim, I seem to have a very similar setup. I still can’t get my Dreamcolor to unlock the color space menu. The footage I’m working with is XDCAM EX shot at 23.97 1080p. Any thoughts?

Hi Geoff,

What you need is an AJA HDP2 Mini-Converter and a DVI-to-HDMI cable.

Go out of your LHi via HD-SDI to the HDP2, and from there, DVI to the HDMI in your DreamColor.

Remember that the DreamColor only displays Deep Color, 709/601 in 60p mode. So, the HDP2 will take care of that, and convert your 24p or whatever other frame rate to 60p for display.

These are my settings for the HDP2:

Video Format: 444 RGB
Deep Color: On
Color Range: SMPTE
Scaling: Scale
SD Format: Anamorphic
Output Format: 1080p – 60/59.94
HDMI/DVI: HDMI

I get simultaneous downconvert to NTSC with my setup, which I find valuable when color-correcting.

Best,
Jim

The Dreamcolor engine will run at 48Hz and 50Hz as well.

Please tell exactly how it’s hooked up.

Ok so backing up for a second here –

I too am running a KONA LHi-RO with a Mac Pro, and using HDMI to send signal to my HP Dreamcolor monitor. I’m working in FCP 6.0.6, and I want to use the monitor as my main video display in Rec.709, and view 1080p XDCAM footage at 23.98. I am currently using the LHi NDD driver from the AJA website.

Has anybody successfully done this?

At this point I am not even sure if I am running the correct driver…disclaimer, I didn’t put this package of equipment together, I’m just the poor sap tasked with making it all work…can it be done?

I download the drivers, get the monitor up and running, but I can see that the image is stretched and the correct color space is grayed out when I try to select it on the monitor, and of course I try to rectify this by selecting what seem to be the right options in the AJA control panel and FCP preferences, and then I just get nothing and have to start all over again.

Is there a crucial step that I missed? Thoughts would be greatly appreciated

Did you uninstall the drivers first beofre downloading and installing the new ones?

Did you also update the firmware with the AJA Kona Updater (found in Applcations > AJA Utilities)?

Your Kona needs to be in true p mode, not psf. So quit FCP, open the control panel and choose the ‘Setup’ tab. Make sure the 23.98 (et al) box is checked and also the 1080 progressive box is checked.

Then, open FCP and choose the 23.98p easy setup that matches your footage. Problem is, I’m not sure if there’s a 23.98p HDV setting. i can check in the morning. If not, you can always edit in a ProRes timeline and use the 1080p 23.98 ProRes easy setup (control-q).

Uh, yeah.

The part that you are required to send the monitor an RGB signal over HDMI- the Dreamcolor THEN converts that signal into Y’Cb’Cr in the Rec709 color space.

You really need to follow Jeremy’s article here on the cow.

jeremy, thanks for the proRes tip, i’ll give that a shot after i get home today.

gary, i agree with you. could you provide a link to that article? i’ve been hearing about it but haven’t been able to dig it up.

thanks again,

Here’s some screen shots of the how the Kona control panel should be setup. This is from an ioExpress as the LHi is working at the moment, so it might look a little different, but the parameters are exactly the same. Now, Quit FCP. Then…

First, the Setup tab:

Then the HDMI tab:

Please note that you can change the Color Space to RGB 8 bit as well.

Then reopen FCP and hit control-q and choose the proper 1080p23.98 XDCam easy setup (I have chosen one of the three that is available on this ioExpress system, it might be different for the LHi):

HTH,

Jeremy
