Welcome

Below partners will find delivery specifications required by Netflix; however, some of these specifications may not apply to your production. Please refer to your Netflix Delivery Requirements List or your Netflix Representative to verify which assets apply to your delivery. 

 

Table of Contents

 

1. General Asset Requirements

There are no exceptions to the following requirements, unless previously approved by your Netflix Representative.

  • Source material must be uncensored.
  • Content must be delivered as long-play and cannot be split into multiple deliveries, e.g., if the content is 90 minutes in duration, a single asset with a 90-minute duration must be delivered. Two (2) deliverables with 45-minute durations will not be accepted.
  • PSE (Photo-Sensitive Epilepsy) Compliance testing (e.g. Harding, Tektronix, or any other algorithm that complies with ITU-R BT.1702-1 guidelines) must be performed for all animated content.

 

2. IMF Specifications

2.1 Packaging

All deliveries to Netflix must be compliant to either SMPTE ST 2067-21:2016, SMPTE ST
2067-21:2020 or SMPTE ST 2067-21:2023 Interoperable Master Format (IMF) Application #2E. Packages containing immersive sound must additionally comply with SMPTE ST 2067-201:2019 Immersive Audio Bitstream (IAB) Level 0 Plug-in.

Netflix IMF Packages should be created directly from the color timeline out of a capable color grading tool OR from an intermediate mezzanine asset. IMF Packages must be delivered in the highest quality and resolution, including High Definition (HD) and Ultra High Definition (UHD). Netflix may explicitly request other resolutions.

If you are creating your IMF package from an intermediate mezzanine asset,  Netflix recommends:

HDR Delivery: 

  • Uncompressed 16-bit TIFF (.tiff)
  • Resolution and aspect ratio must match that of the delivered IMF: UHD (3840x2160) or HD (1920x1080).

SDR Delivery

  • 10-bit or 16-bit DPX (.dpx)
  • Resolution and aspect ratio must match that of the delivered IMF: UHD (3840x2160) or HD (1920x1080).

If creating a mezzanine asset is necessary for your IMF packaging workflow and you need additional guidance, please reach out to your Netflix representative.

The final IMF package must contain the following:

  • 1 Asset Map XML file.
  • 1 Packing List XML file.
  • 1 or more Composition Playlist (CPL) XML file(s), representing a single audio language each, containing.
    • For titles mixed in Dolby Atmos®
      • 1 image virtual track.
      • 1 IAB virtual track.
      • 0 or 1 surround audio virtual track (6 channels).
      • 0 or 1 stereo audio virtual track (2 channels).
    • For titles mixed in 5.1 surround
      • 1 image virtual track.
      • 1 surround audio virtual track (6 channels).
      • 0 or 1 stereo audio virtual track (2 channels).
  • All MXF Track Files referenced from the ingested CPL, that have not previously been delivered.
  • Volume Index and Output Profile List XML files may be present, but are not required.

For titles mixed in Dolby Atmos® and delivered in IAB in IMF, 5.1 and 2.0 (channel-based) audio tracks are optional within the IMF. 5.1 audio is required as a separate Content Hub delivery for dubbing reference only. Deliveries containing only image and IAB tracks, i.e. no channel-based stereo/surround audio track(s), must be compliant to SMPTE ST 2067-21:2020 (since the absence of channel based audio tracks is not supported by the 2016 edition of the standard).

Special consideration must be taken for 29.97 or 59.94 IMF deliverables. The total number of frames contained within a 29.97 or 59.94 IMF CPL Segment must be divisible by 5 to preserve integer value audio samples. If necessary, trim the picture and audio by the required number of frames (1, 2, 3, or 4) before wrapping IMF to ensure total frames per Segment are divisible by 5.

Note: Track files containing timed text essence are not currently supported.

2.2 VIDEO

2.2.1 GENERAL

  • Netflix requires video to be delivered at their native frame rates. Netflix defines this to mean the original capture and editing frame rate. If it was originally a film, Netflix requires the native film frame rate (23.976p, 24p or 25p). This is often different from the frame rate that is used for tape, archival storage, and delivery to broadcasters (typically 29.97i Drop Frame, or 25i). No 3:2 Pulldown flags allowed.
  • Netflix requires video to be delivered in the original aspect ratio (e.g. Netflix will not accept a 4x3 version when a 16x9 version was originally created).
  • Video must consist of the full feature or episodic program with one (1) second of format black and silence at the head and tail of the program.
    • For redeliveries, supplemental IMPs may include video inserts only OR a full video track replacement + any combination of full audio track replacements as applicable.
    • Supplemental IMPs must reference all MXF track files which have not been previously successfully delivered and ingested.
    • Please confirm with your Netflix representative before proceeding with a full video track replacement supplemental IMP OR a new complete IMP for any redelivery.
  • Video must not contain commercial blacks.
  • Video must not contain color bars, bumpers, advertisements, slates, ratings cards, FBI warning cards, VITC time code, placards, overlay branding or website link callouts before, during and/or after the program. URLs present during end credits are permissible.
  • Video must be non-subtitled. Netflix defines “non-subtitled” as the presence of main titles, end credits, narrative text, location call-outs, and other supportive/creative text, but no burned-in subtitled dialog, regardless of the language in the primary video. This does not apply to textless IMF deliveries (see Section 2.4).
  • Track files containing image essence mastered in Dolby VisionTM must embed dynamic metadata for color volume transform within the video track file. At a minimum, L1 Dolby VisionTM metadata must be present for every frame in the track file. Note: We do not support material mastered only for HDR-10 distribution.

2.4 TEXTLESS VERSION IMF PACKAGING

Netflix may request the delivery of a textless version IMF package in addition to the texted IMF delivery. Such a textless version IMF package must be created and delivered after the texted IMF package is approved by Netflix. Additionally, the following requirements apply:

  • The textless version IMF package should be created as a supplemental IMF package. That supplemental IMF package must be based on the last approved texted IMF package successfully delivered to Netflix.
  • A textless background/backplate must be included for any shot/sequence of the content that contains on-screen graphic text. Replacing the entire video track with a full-length textless version is acceptable if the content includes a significant amount of texted shots throughout.
    • Please confirm with your Netflix Representative before proceeding with a full-length textless version video supplemental.
  • The textless version IMF composition must not change or replace the audio/IAB track(s) of the approved texted IMF delivery. This applies even if a full-length textless version with an entire video track replacement is approved by Netflix.
  • Textless inserts must have image properties identical to those of the texted IMF package, e.g. no changes in image resolution, color space etc.
  • Dolby VisionTM mastering metadata trim values for textless inserts must be identical to the associated values in the texted IMF package, i.e. any changes in image characteristics due to removal of on-screen text must not be accounted for.
  • Textless inserts must be provided cut-to-cut (i.e., the textless insert should not begin or end in the middle of a shot, fade, dissolve, or other transition; instead, the entire shot(s) should be provided).
  • Graphic overlays such as emojis or text balloons should be considered texted elements.

 

3. AUDIO MASTERING & ARCHIVE SPECIFICATIONS

3.1 Audio Prerequisites

Discrete audio is required, except in the following circumstances:

  • When muxed audio is inherent to the source, such as audio in an IMF, Quicktime or Atmos® BWAV ADM container.
  • Interleaved Secondary Audio .wav deliveries.

48k/24bit sample rate and bit depth for Original Language Mix or M&E Mix - applies to Stems and Mix Masters.

All audio must sync to the final picture, including 1 second of black before the program start FFOA, and 1 second of black after LFOA.

Printmasters, M&Es and stems may include standard 8 second Academy leader and 2-pops.

For all titles, 5.1 audio is required and 2.0 is optional.

Mono audio is acceptable if the program’s original source is mono and no stereo and/or 5.1 mix exists. Mono audio must be duplicated on channels 1 & 2 and delivered as 2-channel.

3.2 Audio Mix Requirements

  • We recommend setting True-Peak limiters on all beds and objects at -2.3 or lower. Loudness should be checked via a 5.1 rerender.
  • For Atmos® mixes, delivering 5.1 is required and 2.0 audio is optional. The 5.1 and 2.0 re-render outputs must conform to Netflix loudness specification. 5.1 and 2.0 must conform to the Netflix peak specification only if they are delivered for streaming. We suggest achieving this by limiting the output from the renderer, rather than lowering beds and objects.
    • Atmos® - Delivered to picture finishing facility for IMF creation and streaming.
    • 2.0 - Optional.
  • All beds and objects are encoded and will always be audible. A printmaster may utilize a composite of all bed material OR multiple beds, but not both.
  • For all series/doc/unscripted/comedy content, beds and objects must be separated and groups labeled as “Dialog”, “Narration”, “Group ADR”, “Music”, “Effects”, “Backgrounds”, or “Foley”. For film content, DME separation must be maintained whenever possible. See BWAV ADM Creation Guidelines for a full list of acceptable group labels. Fill the 128 channel ADM file before summing Dialogue, Music and Effects material.
  • If an 85 db reference theatrical mix is created, two complete sets of deliverables are required. One for theatrical, one for near field.
  • Leader and sync pop are preferred but not required. The IMF vendor will sync Atmos® in the IMF.

  • For Original Version: Provide 5.1 Dialog, Music and Effects stems that equal the 5.1 mix when combined.

3.2.3 Near Field 2.0 Stereo Mix - Mastering and Archive - Original Language Version

  • Use 79dB SPL or 82dB SPL as your standard reference level for mixing.
  • Provide a Lo/Ro or LT/RT mix with -27 LKFS (+/- 2 LU) dialogue loudness using ITU-R BS.1770-1 measured over entire program.
    • Lo/Ro mix is preferred.
  • Lo/Ro or LT/RT mix to be mono compatible.
  • Do not exceed +18dBu (-2 dBFS) maximum level (true-peak) over reference of -20 dBFS, achieved by peak limiting and not lowering the mix level.

        • Channel format should be determined by the re-recording mixer to match the intent of the original mix.

3.3.2 Near Field 5.1 Surround M&E Mix

  • Provide a fully filled 5.1 surround submix containing only Music & Effects (no dialog).
  • Ambiences and foley fill should be included to correctly match the original mix. Any non-dialog sound present in the main mix must also be represented in the M&E mix.
  • All levels should mirror what was used for final Mastering and Archive so that any newly added dubbed dialog can be mixed in easily later.
  • Optional tracks are required in addition to the 5.1 M&E when necessary.
  • For Dolby Atmos® mixes, the 5.1 M&E should be rendered from the Dolby Atmos® M&E.
