Hi Alan,
I think you’re right that it is an issue caused by the scaling… and either the GPUs are getting data too slow over the shared PCI or are too slow themselves. I will be replacing the GPUs soon and so that will be one test…
I might test playback with some s3d 4K HD set to 1/2 res debayer… that would avoid any scaling by the GPUs, if I’m thinking about it right…

Hi Sascha,
There are two red-rockets in there… any trick to tell if they’re both being utilized?

Try duplicating the .tif a few times and renaming to make a sequence out of them… Occasionally Resolve doesn’t play well with single-frame image sequences…

Hi Miran,
It sounds like you are using the still store preview with the alpha mix mode, and DaVinci won’t render the still store part. If you want to render the final composite, you should bring the still BG into the media pool (I usually make it an image sequence first) and put in in a layer below the green screen footage. When you pull the key and connect that node to the alpha output, you should see it as expected without having to play a still.

[Joakim Ziegler] “Apple seems to be moving back to Nvidia for GPUs.”
Right on cue, somebody seems to have drilled down on the Mountain Lion Developer Preview 4 and found GTX 680 / kepler support. Dave P. posted this over at macrumors:

Hi Gabriel,
I think you’ll be able to experiment and learn the software with just about any display. You might be looking at an inaccurate image, but learning the layout and tools it won’t make a huge difference.
Discovering what you think is pleasing/seamless/expressive does require an accurate and consistent display, and I don’t think anybody has figured out a solution in your price range. My recommendation however, would be to look for a used HP dream color (HP LP2480zx). I like as an entry-level monitor for these reasons:
– While not the most stable, you can get a fairly inexpensive calibration probe and HP’s software that will allow you to easily put it into Rec. 709 in a very short time.
– It doesn’t suffer from the power management of consumer plasmas.
– It’s a 10-bit display and Rec. 709 gamut so it represents HD material very well.It has a high black level like most LCDs, but comparable to a FSI 2461-w. It also is picky in that it only takes RGB true-progressive signals, and so you might need an AJA HDP2 converter to work with certain output signals. You can find a lot more info on that elsewhere on COW.
I’ve tested it in a dark room along with a DCI projector and FSI 2461w, and the image holds its own.
However, I’ve also returned 5 in a row where the panel died or didn’t meet my expectations. HP basically never supported it, and they’re no longer selling it. But if you find a used one at that price, it might be the closest to solving your dilemma.

Hi Markus,
We bring projects from Lite to the full version almost daily, and have had no problems. You are restricted to HD but none of the other limitations affect the conform. We usually just export the project from one machine and import it on the other for color grading.

Here’s a rumor that goes out on a limb a little more:

Hi Chris,
Are you on 8.2? I had this problem repeatedly on an earlier version but not on 8.2..
