Activity Forums DaVinci Resolve Lack of contrast on output

  • Lack of contrast on output

    Posted by Phil Side on January 17, 2012 at 5:17 pm

    I’ve been playing around with Resolve Lite, and I’m finding that clips which look good within Resolve have a signifcant lack of contrast when rendered. Choosing “Unscaled Full Range Data” on the render dropdown improves things quite a bit, though it’s still not perfect.

    I don’t really understand the implications of changing the “Unscaled Full Range Data” dropdwon, and I don’t know whether I ought to be making the same change in the Video Monitoring section.

    The System is Windows with a single Nvidia GTX 560 Ti. The monitor is a Dell U2711. I’m encoding to H.264 and the final destination for most of my work is Vimeo.

    If anyone could offer any pointers, it would be much appreciated.

    when you check the rendered h264, do you use quicktime, or VLC?
    Even players will play some file types differently.

    (my h264 renders are less saturated played on quicktime, and they’re just about right in vlc)

    I tried VLC, WMP, and Quicktime. Of the three, WMP was marginally the best, but they were all a long way a way from what I was seeing within Resolve. They all improved when I changed to the “Unscaled Full Range Data” setting.

    Are you monitoring through a Decklink card to a calibrated monitor? If not, then what you see is not what you get. 

    I have found that Resolve beta on Windows renders differently than Mac version, when it comes to selecting “full range” or “scaled” on render. On Windows, it seems impossible to get out a full-range render, even if you choose that option. It’s scaled. And the “scaled” option is useless, the blacks are way up and whites are down. On a Mac it works as it should.

    You could also check the preferences- are you monitoring full-range or scaled data? I prefer to monitor “scaled” because output is for broadcast. Not sure about web stuff..

    I’m not monitoring through a Decklink card, but according to the config guide, I shouldn’t have to. I am using a calibrated monitor.

    It sounds as though we’re both seeing the same thing when the output render is set to “scaled” – low contrast, low saturation. I have tried changing the scaled/full setting on the Video Monitoring tab. It didn’t seem to have much effect, certainly not the same effect as making the equivalent change in Render tab.
