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.

2. IMF Specifications

2.1 Packaging

All deliveries to Netflix must be compliant to either SMPTE ST 2067-21:2016 or SMPTE ST 

2067-21:2020 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.

IMF packages must be created from the Video Display Master (VDM), or directly out of a capable color grading tool, and must be delivered in the highest quality and resolution, including High Definition (HD) and Ultra High Definition (UHD). Netflix may explicitly request other resolutions.

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 in 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 df, 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 feature program with one (1) second of black and silence at the head and tail of the program.

• Video must not contain commercial blacks.
• Video must not contain color bars, bumpers, segment recaps or previews, 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 a single 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.

• 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.
• 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.
• The textless version IMF composition must not change or replace the audio/IAB track(s) of the approved texted IMF delivery.
• 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; instead, the entire shot should be provided).

4. Non-Graded Archival Master (NAM)

The Non-Graded Archival Master (NAM) is a fully texted image sequence of the non-color graded, fully conformed and locked picture, including final VFX, rendered in a single scene-referred color space with no output or display transform applied. The archival resolution will be specific to the project and will be communicated by Netflix. At minimum, the archival resolution will be no less than 3840x2160 (UHD) and must include the final delivery active picture area with no cropping, matting or masking applied over the image. If your primary capture format was less than 3840x2160 (UHD) please reach out to your Post Production Management or Creative Technologies Workflow contacts at Netflix to discuss your best options.

The file format of the Non-Graded Archival Master (NAM) will depend on the transfer function of the scene-referred color space as well as the bit-depth of the source files:

 

Color Space	Transfer Function	Source File	Format
Scene-Referred Color Space (i.e. camera native color space, CF color, T-CAM or ACES*)	Logarithmic	RAW or Compressed in More Than 10-Bits	16-bit DPX (.dpx)
		Compressed in 10-Bits	10-bit DPX (.dpx)**
	Linear	RAW or Compressed in More Than 10-Bits	Uncompressed 16-bit Half-Float OpenEXR (.exr)
			ZIP Losslessly Compressed 16-Bit Half-Float OpenEXR (.exr)
			PIZ Losslessly Compressed 16-Bit Half-Float OpenEXR (.exr)

*ACES projects must be Linear / AP0, per SMPTE ST 2065-1. ACEScct encoded files will not be accepted.

**10-bit DPX (.dpx) will be accepted only if 50% or greater of the primary capture footage was 10-bit or lower.

Frame Numbering

• Frame numbering must be continuous within each delivered asset and must always be consistent across all picture archival assets.
• For feature films working in reels the frame number must be continuous within each reel. The initial frame number for each reel/segment is at the discretion of the finishing partner.

Textless

• Textless inserts must be delivered with image properties identical to the corresponding texted asset.
• Textless inserts must include a textless background/backplate for any shot/sequence of the content that contains on-screen graphic text. If the content includes a significant amount of on-screen graphic text throughout, it is acceptable to create a full-length textless asset rather than providing segmented frame ranges.
• Textless inserts must be provided cut-to-cut (i.e., the textless insert should not begin or end in the middle of a shot, the entire shot should be provided).
• Textless main titles or credits do not require a distinct naming convention from other textless inserts.
• Textless inserts must be numbered to match the numbering of the corresponding texted shot/sequence.
• Graphic overlays such as emojis or text balloons should be considered texted elements.

Quicktime Wrapped Non-Graded Archival Master Exceptions

Quicktime wrapped compressed formats may be acceptable under limited circumstances, particularly in Animation workflows where source media is entirely compressed. Please consult Netflix to determine if QuickTime delivery is acceptable for your project.

Minimum acceptable compressed formats:

HDR: 12-bit, DNxHR 444 or ProRes 4444 XQ 

SDR: 10-bit, DNxHR 444, or ProRes 444
