FAQ

Q. Which version of Media Composer is the Legalizer LUT compatible with?

A. The Legalizer LUT is compatible with Media Composer v8.3.0 to v8.8.5, on Mac or PC. However there is a problem with v8.6.0 and v8.6.1 where color channels are clipped at incorrect levels. We recommend updating to v8.6.3 or above.

 

Q. What range of signal levels does the Legalizer LUT limit to?

A. The Legalizer LUT limits Luma between 0% and 100% and RGB components between 0mV and 700mV. This is very conservative legalizing and is well within broadcasters' tolerances.

 

Q. Will the Legalizer LUT ensure my masters are EBU-R103 compliant?

A. Yes. All material passed through the Legalizer LUT will be within the EBU-R103 specification.

 

Q. Why can't I just use the Media Composer 'Safe Color Limiter'?

A. The 'Safe Color Limiter' effect works, with the correct settings, but offers hard clipping only.

 

Q. What is the advantage of soft-clip legalizing over hard clipping?

A. Soft clipping gives more visually pleasing results, retaining detail rather than simply clipping off any illegal values.

 

Q. Will the Legalizer LUT legalize video in editors other than Media Composer?

A. No. When using the LUT in Premiere Pro and FCPX, signals are clipped to the incorrect levels. The Legalizer LUT has been designed and tested specifically for Media Composer. LUTs for Premiere Pro and FCPX will be released at a later date.

 

Q. What formats will this LUT legalize?

A. The LUT was made for all Media Composer HD formats. It will also work with any of the Media Composer project formats labeled '709', including UHD and 4K.

 

Q. Is this a real-time process or will I need to render?

A. Using the Legalizer LUT in Media Composer is real-time. There is no need to render.

 

Q. Can I use the Legalizer LUT in a shared Avid environment?

A. Yes. When the LUT is used in a project, Media Composer automatically creates a copy of the LUT and places it in the project folder. In a shared environment, anyone can open a sequence with the LUT applied without having to install the LUT themselves.
