Netflix is available in over 190 countries, and a rapidly growing number 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. For non-fiction titles, please check with a Netflix representative for depth of fill required.
Please deliver a fully-filled Music & Effects Package as long-play, discrete channels according to the Netflix Nearfield true-peak requirements (Sound Mix Specifications and Best Practices) with the program content of each file conformed and in sync with that of the final media delivered to Netflix. M&E levels should generally match the original mix. Do not modify Music levels at all, and do not modify FX levels beyond what is required for a properly filled M&E. Optional channel assignment should match that of the top-level mix. Please name files according to Netflix naming conventions outlined here.
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.
Preparing M&E assets
The audio deliverables should sync to the final IMF picture. Head leader and pops may be present on these assets.
A step by step guide to create M&E assets can be found in the M&E Creation Guideline article.
All pertinent information regarding the M&E asset should be included in the file name. Please follow the instructions in this Naming Convention article to properly name the files before uploading to Content Hub.
M&E QC Requirements
To ensure viewers experience an accurate presentation of the creative intent, the following assets are required for M&E QC:
- Reference Video (ProRes, DNxHD etc.) - The same picture used during Mix. (MnE Request).
- M&E Track (5.1 wav) - MnE Request.
- Optional Tracks (5.1 wav) - MnE Request (*see below).
- Dialogue Guide (Stereo) - MnE Request (*see below).
- Print Master (5.1 wav) - This is uploaded to the Printmaster Request in Content Hub (per episode number).
*What is a Dialogue Guide? A Dialogue Guide is a mono mix-down of the final mixed dialog stem. It is used and usually included with an M&E for reference.
*What is an Optional Track?
An Optional Track is a separate audio track containing valuable but language-specific material. For example:
- Language-specific walla, crowd chants, cheers.
- Dialogue from TV show playing on-screen or from real-life/historical people.
- Language(s) being spoken that is foreign to that of the original language of production.
- Vocals from a character singing on-screen (It may be dubbed IF the songs lyrics are story pertinent).
Optional tracks also contain dialogue of other languages that are spoken in a Film/Show. You may provide any number of optional tracks in any channel configuration from Mono to 7.1.2. Below are some examples of how to organize them. When in doubt, add it to the optional tracks.
- Optional A - By CHARACTER: (etc etc)
- Optional B - By LANGUAGE: (etc etc)
- Optional C - Group ADR and Walla (by Language if necessary)
