Hello Paul,

there has been a couple of threads on this topic already.

Graphic text elements issue - ACES in DaVinci Resolve

Hi, When using ACES(ACEScct) in DaVinci Resolve, I am having trouble getting graphic text elements (like maintitles and end credits) looking as intended - often they look rather bad, with very bad staircase(jagged) edges and color shifts. This applies both to text displayed over image and on black. The problem seem to persist no matter the bit depth or if the source file format is TIFF, PSD or PNG. Assigning the correct IDT (usually sRGB) does nothing to remedy said issues. Have anyone exper…

Preserving the look of sRGB graphics

I have a recurring problem with given graphics from clients in an ACES workflow. For example if I get a packshot which has a sRGB 100% white backgorund and the product in front of it. If I bring that in with a sRGB IDT and view it through the RRT/ODT everything looks flat and wrong. And white is no longer white, of course. I would need the original display-referred look. You can grade that a little to it’s original look, but I never really get there. The same happens with logos and any kind …

I don’t know if you had a look at those.

But ACES works for grading only. When working on a project with logos etc., I either have to transform the clips manually so logos etc. won’t get changed or I grade in ACES first and then import the graded footage into another project and there I can add logos on top.

Hopefully, you would not have to do that. Otherwise working in ACES would be a real pain. I have been doing a couple of tests with your logo and I cannot reproduce your issue. First one was with Nuke.

It seems to match perfectly. I also did a test in Resolve 15 (I am not a Resolve User so hopefully I used a correct setup).

The trick as you already know is to use your ODT as an IDT for your logos. This process is called inverted IDT and allows to bypass tone-mapping for any logo you may have. If I may : did the client provide a proper logo file ? The JPEG I downloaded from this forum thread was very low quality.

Thanks,
