ACES - Heavily Pixelated PNG Graphics

Working under ACES and using PNG images, they are pixelated, jagged or heavily aliased and unusable.

This looks to be affected by the timeline’s resolution. For example, If I have graphics created for 4096x2160 DCI and place them in a project with a 1920x1080 HD timeline resolution (center crop no resizing,) the graphics are heavily pixelated. However, if I change the project's timeline resolution to 4096x2160 DCI, the issue is resolved and the graphics appear as they should; I’ve not tried rendering yet. FWIW, under the ACES color management, with REC 709 output...I've set the images input as REC 709. Image scaling settings have also been set to Smoother and Anti-alias to On.

Under the same timeline resolution scenarios as above, and changing color management to DaVinci YRGB, the aliasing issue is still apparent, however, minimal by comparison.

Is there a resolution or work around to this issue?

Try setting Image Scaling to Smoother.

Try setting Image Scaling to Smoother.

I already have Image scaling settings set to Smoother and Anti-alias to On, the issue persists. At this point...logos, lower thirds or any overlays using graphics with alphas would have to e done outside of resolve using AE, Motion or other package. Using DaVinici YRGB color management, the result, though much improved, isn't crisp or what I'd find acceptable.

Same issue here. And it's been going up for a while under Resolve 15 too. Awful aliasing in ACES. Better in RCM but still not professional-grade (text edges look much better on other software, such as Premiere).

Just adding my system specs here...

Mac OS High Sierra: 10.13.6,

same here, what can we do, its a massive problem for me

same here!
