Color in ACES - VFX in LOG

(Gillian Eve) #1

Hi Everyone,

What workflow would you suggest upon the following scenario?

Footage is being shot using a R3D - RedWideGamutRGB - BT1886 - Client wants to work in ACES.

We figured out it would be best for us to work our VFX in EXRs RWG-LOG3G10, We would however need to revew shots as per final output ACES - how can this be possible in Nuke/AE? We need to understand what method to use to convert LOG3G10 to ACES, . Is this possible and how would you suggest converting the LOG3G10 to ACES?

You do not want to write Log3G10 to EXR files. EXR should be linear.

OCIO in Nuke, using the ACES 1.0.3 config, can convert between different colour spaces including ACES and RED Wide Gamut (linear or Log3G10).

OCIO is also available as a plugin for After Effects, which can emulate the Nuke colour pipeline.
