JOHN FRITH, HEAD OF IMAGING AT MPC ANSWERS 3 QUESTIONS ABOUT HOW AND WHY THE COMPANY USES ACES IN VIRTUALLY ALL THEIR WORKFLOWS.

###Q: How are you using ACES at MPC?

A: We are fully setup to support ACES at MPC and welcome any ACES based projects.

We’ve worked on a number of (large) feature projects using ACES, all graded by Peter Doyle at Technicolor. Most of these features are due to be released in 2016 so we’re in the middle of the postproduction process and can’t talk about them specifically but they will be among the “tent pole” releases of next year.

###Q: What benefit do you see using ACES?

A: One aspect of ACES that is most definitely a benefit for us is having a common colour space for file turnover. In fact, at MPC we do all our Assets/Texturing work in ACEScg space, then convert to ‘show gamut’. For non-ACES shows our ‘show gamut’ is the hero camera gamut. For ACES shows our ‘show gamut’ is ACEScg. Our on-set stills ingest pipeline has been developed to convert raw stills to ACEScg from a variety of cameras.

By virtue of adopting ACEScg for a texture pipeline, one could say that all our productions are now incorporating an element of ACES.

###Q: What are some lesions learned that you could share with other effects companies regarding ACES?

A: ACES is important development for the industry. The ability to have a common colour space throughout the process and among different companies working on a project is a huge benefit in this era of digital production and workflows. We’re looking forward to ACES being directly supported in many of the applications we use, as that will simplify using ACES. In the meantime, we use the ACES OCIO to overcome this, but not all our tools support OCIO so we also need to create custom LUTs for some tools.
