M&E Creation Guidelines

Netflix is available in over 190 countries, and a majority of our subscribers will consume our titles in a language other than the original. It is therefore imperative to the creative intent of the film or series that the Music and Effects Package reflects the original version mix.

Please deliver a fully-filled Music & Effects Package as longplay, discrete channels according to the Netflix Nearfield loudness and true-peak requirements (Audio Mix Specs and Best Practices) with the program content of each file conformed and in sync with that of the final media delivered to Netflix. In order to facilitate QC, please conform files to Netflix timing of final picture (i.e. no leader or tail). Optional channel assignment should match that of the top-level mix.

For selected titles, Netflix will provide specific notes for the mixing of the M&E elements. Unless those notes specify otherwise, please apply the following general guidelines to the M&E mix and contact Netflix Post or International Dubbing if they cannot be followed:


The M&E effects content must match that of the Print Master. Any effect present in the Print Master must also be present in the M&E.
