Apple Pro Res 4444 video looks different outside of Davinci
on Jun 25, 2013 at 11:58:55 am

I'm outputting pro res 4444 video from R3D files in Davinci. As soon as I output into Pro Res it looks drastically different, flat and unsaturated. What's odd is that when I import the same Pro Res file back into Davinci, it looks exactly as I intended it to look. Any ideas as to why this is happening?

Welcome to the wonderful world of color management. Are you evaluating your image on an external monitor. connected through a video IO?

Check in render page if your video levels are set to (auto) instead of scaled to normal video levels.
Ran into a issue with this awhile back.

Unfortunately I only have a 27 inch Imac, which I calibrated the best I could. I'm grading on 2.2 gamma but I have hotkeys set to flip between 1.8-2.5 to check for clips and gamuts.

Also I'm rendering at unscaled as I'm doing some effects work after.

Unfortunately, right now Resolve's GUI image is not color accurate. One of the features in V10 will be the application of a GUI lut, which make it possible to calibrate the GUI display. But that's V10, V9 requires video IO.

Hey Juan,

Is that GUI LUT going to require a strong GUI card?

I have a Windows machine with a Quadro 600 and a GTX 680. I was thinking about purchasing a Titan (due to an earlier post you said that the RAM is a major factor) as a GPU and the 680 for the GUI. Just want to know if that's the best option for now through the rest of the year with Resolve 10.

The application of LUTs is not a particularly taxing operation for a GFX card. I don't think it'll make a huge difference.

Thanks for response Jaun, I've been making progress correcting on 2.4 gamma and flipping between different target gammas
