ACES issue in 15.12.1

PostThu Dec 06, 2018 9:39 am

We are currently working on ACEScc Color Managements under Version ACES1.1 and our footage is Arri Alexa. Attached image the color bleeding we get it under ACES Color Managed, where as there is no bleeding under YRGB CM. How to solve the issue in ACES Color Managed the bleeding issue?

Also for Arri Alexa and RED footages unable to change INPUT DEVICE TRANSFORM or DISABLE IDT which it takes automatically. Do you have any solution for this too?

Attached screenshot of both...

it's been bundled with Resolve for a few years now, look for "neon suppresion" CLF,

it needs to be in linear light so apply to the cam orig in the media pool, or use a transform node to go to linear->use a neon suppresion node->use a transform node to go back to ACEScct

but if you want the orignal, or really anything to do with ACES, then go to:

I must be missing something, why are you not applying an appropriate input transform for your footage?

For RAW video Resolve automatically maps it, check the RAW settings in Resolve, for non RAW video there are input transforms. For Alexa check Alexa and for RED there are various DRAGON/RED options.
