Resolve environment colors different from outside

PostThu Feb 28, 2013 9:42 am

Hello,
I am trying to render out of Resolve, and regardless which codec I use, the colors are dramatically different from colors within the Resolve environment.

When I reimport the rendered file it is consistent with the original, within the environment.

Also tried generating tiffs and viewing in photoshop to see if this is a QT problem. Files look reasonably similar in QT and photoshop.

So in short, within the Resolve environment saturation is much higher, especially in the reds.

Any tips? could this be a driver problem?

Mac Pro 5,1 single processor 2,8 quad core running system 10,8
with 8gb ram
and standard ATI Radeon HD 5770

thanks,
Dmitri

I don't believe the GUI of Resolve is colour managed. Are you viewing your footage on a reference monitor?

I am only using one monitor, an eizo flat panel.

I understand if my colors don't look right on other monitors, then it is a calibration issue, what I don't understand is the problem within one monitor.

some troubleshooting (I assume the color pipeline is not calibrated correctly)

1) Has the Eizo being calibrated?
2) Has the Eizo an internal LUT loaded?
3) has the Eizo a color profile/ICC loaded?
4) If you get a commercial plasma/LCD flat panel and you put that next to the Eizo and you send the same image, do they look "alike" or you see the same difference than the before/after render?
5) if you do a QT or a Tiff or a DPX out fo the resolve, do they all look the same?
6) do you have a LUT in resolve?
7) what you use to calibrate the system/chain?
8) are you in P3DCI, rec709, BT1886, XYZ? which gamma/primary?

I calibrated my monitor with i1pro, 6500 k.

I am using no LUT, and am working on 7D h264 material.



whatever I render to is consistent. Rendered or un-rendered it looks the same in Resolve and different outside.

It looks saturated and tasty in Resolve and grey and washed out in any other environment.

tried QT, photoshop, in a browser all look the same, grey and unsaturated.

I can't figure out where one adjusts or sets Resolve color space, but shouldn't it be using the same icc profiles as every other program?

Would love to solve this problem, any help appreciated.

Thanks

As pointed out on various threads and in the resolve config guide. Resolve does not use the GUI display for color critical monitoring, all color critical monitor is done on an external video monitor. You need to use a decklink or similar video card to feed the image to an appropriate display in order to evaluate color. Not the GUI.

Thanks!

I am a beginner at this, having worked many years in print, which has different issues.

I was advices to get a quatro 4000 video card, to go along with my intalled 5770. or do I get the card you suggested, or do I need both?


all help appreciated.

The quadro 4000 is a graphics card not a video card. Please look at the resolve config guide which covers this and has recommendations for system config.

Ok thanks, I am starting to understand.
Next newbie question:
Can I use my Eizo with the above mentioned DeckLink Studio or Intensity pro and get something resembling reasonable color? Forgive my ignorance but if I am just using flat panels, do I need the Deck link studio card, or is the intensity pro fine. And is this the best way to start out?


and as to vid cards, I have the mentioned standard 5770, is my best option the quatro 4000, would of course like to spend less rather than more, but heard that the other options don't work out so well.

thanks,
D.

Hi, these and many more questions are answered in the config guides. Give the a read and if something is not clear we can clarify.

I continue to read the Config doc, and all I can say is that my technical knowledge is sadly lacking.

So to grade I need a video card, I get that now. The BMD cards seem quite reasonably priced.

I think I will be working only with digital source.

so the next question is graphics cards.

Should I get the quatro 4000, or dump my 5770 and get a GT 120 for the gui and a gtx 570 for image processing, which is a bit cheaper than buying a 4000.

And once more the problem is not that I haven't read the Config guide, the problem is that I don't understand what it means.

How does everyone else know all this stuff, geez.

You mentioned you viewed the image in a web browser, photoshop, and QuickTime. Web browsers are notorious for not handling colors correctly, especially Safari 6.0.2.
Photoshop - I'm not sure how you opened a movie file, but I'm guessing there are some color space options you need to set properly.
QuickTime - also has some issues with gamma. In QT 7, there is an option to use Final Cut Studio compatibility mode, which changes the gamma. Try that.

But really, you should get a Decklink and a video monitor.

to evaluate color in a monitor you might also want to download NUKE (learning edition), even if it puts a watermark, it can handle the color space correctly without ICC.
