3 way too responsive
on Aug 23, 2012 at 11:35:54 pm

I always hated how sensitive the 3 way color wheels were with a muse in resolve when grading prores files. I just downloaded a raw file from the new BMD camera and it is way better. Is there any way to change the sensitivity of the color wheels when using prores and a mouse?

Hi Matt,

What kind of ProRes files give you trouble? Are they Log-C or are you adding a LUT at some point in the chain?

I believe that since Resolve is applying the changes to a fully decoded RGB image, and that there wouldn't be a difference based on the source media. But there would be a big difference if you color before vs. after a LUT.

Cheers,

No Luts applied. I barley have to move the highlight wheel before I get a huge color cast! I have no idea why it does this.

Sure you are using V 9 ?
In 8 I agree, but 9 is totally smooth

Yea its v9. Is there not a setting for the sensitivity. I couldn't believe how much easier it was with the DNG file. I could push the wheels about halfway before it really started to alter drastically.

Heres an example of a neutral image and then a heavy color cast from minimal adjustment to the highlights. This is a prores 422 file from FCP :

well with out seeing your scopes - the sky is all highlights and you have made a push ( not a huge one but a push none the less. Perceptually, I've always found that highlight corrections are more "sensitive" to slight adjustments

Same thing happens in the midtones. My point is I can take a scene from a DNG raw file and push it way further before this strong of a cast happens. It feels much better and I'd love to grade that way. Thats the one thing I like about colorist plugin vs resolve.

That seems like a pretty big movement to me, you should see a rather pronounced color cast on any footage if you move it that far towards one color. I just replicated the same values from your picture with the BMCC sample DNG, and it has a very noticeable color cast.



If the wheels are too sensitive while using a mouse, maybe try doing all your adjustments with the primaries, I think it's easier to have fine grained adjustments using those with the mouse, though they are slower than the wheels.

Thanks ernest. I realize if you replicate the values, then it will be the same. But did replicating those values put your ball on the 3 way that close to the center?
