Netflix Originals: Production and Post-Production Requirements v2.1

Scope
Provide a set of technical requirements for production and post-production workflows to ensure that a high level of quality is maintained throughout the lifecycle of a project from capture to archive. This serves the purpose of future-proofing the content as the Netflix platform and viewing experience continue to evolve.

Please see the Originals FAQ for additional information.

Camera Requirements

4K Resolution:
• Camera must have a true 4K sensor (equal to or greater than 4096 photosites wide).

Recording Format:
• Minimum of 16-bit Linear or 10-bit Log processing
• Bitrate of at least 240 Mbps (at 23.98/24 fps) recording
• Recording format must be set to either:

    • RAW (uncompressed or lightly compressed sensor data)
    • Log color space (i.e. S-Log3, V-Log, CanonLog3, REDLogFilm, BMDLog, LogC)

• No looks or color corrections should be baked into the original camera files.
• Files must maintain all metadata (i.e. Tape Name, Timecode, Frame Rate, ISO, WB, etc.)

Aspect Ratio / Framing:
• Aspect ratios greater than 2.00:1 must be evaluated and discussed with Netflix for approval.
• Framing chart must be shot before principal photography begins, and processed through the dailies pipeline which will be shared with editorial, post-production, and VFX.

Secondary Cameras:
• Any cameras other than the primary camera (crash, POV, drone, underwater, etc.) must be approved by Netflix.
• Test footage should be shot and provided to dailies and post-production to ensure compatibility with primary camera.

Color Pipeline Requirements

It is important to ensure that images are stored in the widest possible color space until the very final stages of the color pipeline. This is easily achieved by using ACES, which keeps images in a high dynamic range, wide color gamut space, and allows the user to simply select the Output Transform for the target viewing display. This can also be achieved while working in the dominant camera color space with careful, pro-active color management and the use of conversion and viewing LUTs. Both methods are outlined below. Please contact us with any questions.

Color pipeline documentation must be shared with production and post-production ahead of the first day of photography.

For Non-ACES Pipelines (Camera Native + Show LUT):

  • Working Color Space must be defined and communicated to all departments.
    • Examples: Sony SLog3-SGamut3.CINE, REDLogFilm-DragonColor, Panasonic V-Log-V-Gamut, CanonLog3-CinemaGamut
  • Output / Show LUT must be defined and shared between all departments.

For ACES Pipelines:

  • ACES Version (i.e. v1.0.2) should be defined and shared between all departments.

On-Set & Dailies Color:

  • CDLs only
    • No secondaries, keys, or power windows to ensure compatibility in post.
  • Order of operations is critical
    • CDLs must be applied before Output Transform.
    • See diagram below.
  • On-set and dailies monitors must be calibrated to the Rec.709 / BT.1886 standard, or equivalent HDR standard (i.e. PQ / SMPTE ST.2084)

Dailies Requirements

For all scripted projects, on-set or near-set dailies services are required in order to provide efficiency for downstream processes.

Color & Sync:

  • Production sound must be synced to camera footage for editorial media.
  • Color should be applied, following the color pipeline defined above.
    • If CDLs exist, they must be applied before the LUT.
    • No secondaries, power windows, or keys in dailies.
  • Grading monitor must be calibrated to Rec.709 / BT.1886 standard, or equivalent HDR standard (i.e. SMPTE ST.2084).

Editorial and Review Proxies & Metadata:

  • ALEs / BINs must be generated with all camera and sound metadata including columns with CDLs and LUT names.
  • Editorial media and proxy deliverables must be generated from original camera RAW files, not from a secondary proxy.

Back-up / Data Verification:

  • Two or more back-up copies of all original camera footage and audio with MD5 checksums must be generated.
  • Footage must be QC’d for possible issues, referencing camera reports with scene/take information.
  • Archival of camera RAW footage, audio, and color information should maintain original directory structure, filenames, and metadata that were created by the cameras, audio recording devices, and dailies software to one or more of the following:
    • LTO-5, LTO-6 or LTO-7 tape in LTFS format
    • Netflix’s cloud-based Content Hub
    • High-speed RAID-protected external hard-drive
  • Once multiple backups are complete and verified at another location, the camera magazines / recording media may be cleared.

Post-Production Requirements

Conform & VFX

  • Framing chart must be placed at the head of all timelines (per episode / reel).
  • Conform and VFX pulls must be:
    • Minimum resolution of 4K.
    • One of the following file formats:
      • 16-bit EXR (.exr) in ACES, or camera’s Linear color space
      • 10-bit DPX (.dpx) in the camera’s Log color space
  • VFX pulls should include CDLs, LUT (if any), and dailies color reference.
    • Round-trip tests should be run to verify dailies color match between VFX and editorial.
  • EDLs, AAFs, or XMLs should reference back to original 4K files for the online conform.
  • Proxy or intermediate files should only be used for reference during editing, previews, and/or audio-dub/timed-text generation.

IMF Master

  • IMF must be generated from a final uncompressed Video Master (i.e. DPX, EXR, or TIFF) and not from a compressed file (i.e. ProRes, DNX).
  • Resolutions supported:
    • UHD: 3840×2160
    • 4K: 4096×2160 (if finished in 4K or higher)
