Experience with grading on a Christie 2K projector ?
I’m so fortunate to have a big cinema center in the same building as my office. I’ve now got a green light to go ahead and do technical testing in one of the theaters. I’ll have a Christie 2K projector to my disposal.
I’ve been told it will need a dual-link XYZ signal, preferably 12-bit.
DaVinci outputs 10-bit if I’m not completely off here. I don’t know if this will be crucial for projection or not, but I hope it will work out nicely.
Does anyone have any experience, either with Christie or any other digital cinema projectors?
Oh, and by the way.. Here’s the beauty. 🙂

Well you are just plain luck, really. I think one of the great things about a projector like this is that they are usually Xenon light source and easily calibrated and that the light source stays consistent until it’s end of life. Pipe dual link from your Decklink card and find out if the projector is setup for 709 or p3 apply lut…

I was thinking I’d apply the XYZ LUT that comes with Resolve and see how that goes. I have no clue how to get a new LUT like this.. hmm.. Crossing my fingers the calibrator at the cinema will have the tools to make one.

We had the technical testing today, and it went very well. Almost plug-and-play.
I had my Mac Pro with DaVinci Resolve and Decklink card play a project with an rgb2xyz output LUT. Then the fun began with hooking it up to the projector.
There’s a lot of settings, so we spent about two hours understanding different settings before we got in range. We didn’t understand the Scope and the Widescreen settings on the Christie projector at first, so we made a grid in Photoshop and used it as a still through DaVinci.
When we figured out what the projector did in the two different settings, it was basically just a simple setting in the timeline/format output resolution, and we were up and running. Colors looked killer!
Happily, it looked very close to what I’ve been doing in my little suite with a Panasonic broadcast monitor.
Next step in the progress is to make a table so it’s possible to work with comfort for long sessions, and to have enough table space for a control surface.

wow … you are so lucky that they let you do that …!!!!

Was your output in 2k or HD? I’m looking to move on Resolve but It’s hard to find informations about 2K output. It would be really appreciated to have feedback about performance with 2K/4K output with Resolve on mac. I’m not sure about the exact hardware I’ll go with but it will be something like a 12 core with a Cubix, 2 FX4800 on on SAN in fibre……
Thanks!

Yup, I had 2K output via dual-link HD-SDI. The Decklink HD Extreme 3D supports 2K output.
