Content Hub (Web UI) Upload Tool


A web-based UI with drag-and-drop functionality is available to upload assets into Netflix Content Hub. A user account with project-specific permission is necessary. Please request access from your Netflix Post Production or Distribution contact if needed. Please follow the file naming and folder structure outlined in Picture Archival Assets: Folder Structure and File Naming Convention.


API Upload to Content Hub


Deliver LTO or HDD to a partner with access to a Content Hub API-integrated system. Coordinate shipping of assets with your Netflix Post Production contact and follow naming and folder structure outlined in Production Assets: Folder and File Naming.


Preparing Physical Assets for Iron Mountain (IM)

  1. Only LTO tapes and physical film deliverables should be sent for long term storage at the Iron Mountain facilities. If you have paper deliverables or hard drives, ask your Netflix post contact for guidance.
  2. Where possible, LTO tapes should be made in duplicate. The primary copy should go to Iron Mountain, and the secondary copy should be held by the Partner at least until production wraps.
  3. To package your materials for IM you may use your own sturdy boxes, or boxes can be ordered from IM (Email imfscustomerservice@ironmountain.com with what you’d like to purchase & the Netflix account number)
  4. If shipping multiple shows at once, they must be arranged in separate shipments.
  5. Original Camera Files (OCF), Original Production Audio (OPA), and Production/Dailies Assets should always be placed in separate boxes from Archive Deliverables (Final DI, NAM, Editorial, Music, etc). OCF/OPA/Source Materials in one box and Archive Deliverables in another box.
  6. LTO tapes must ALWAYS be packed standing on edge, not flat on their side. To prevent tapes from falling on their side during transport, please include enough packing material sufficient to keep tapes upright and insulated from drops. 
  7. Please refer to the Preparing Physical Assets Guides, Domestic or International, and the Packing Instructions for more detailed information and box manifest templates.


 LTO Specification

  • LTO 6, 7 or 8
  • LTFS Format Specification: v2.0.0 (or later)
  • Write data to the cartridge without LTO hardware compression.
  • Error Correction must be enabled
  • MD5/MHL checksum manifest (for Dailies and Picture Mastering assets)
    • Stored in the folder of files upon which the checksums are being run
  • If frame sequence is larger than LTO capacity, please span multiple tapes sequentially and label accordingly (Tape 1 of 2, Tape 2 of 2, etc.)
  • If project is broken into reels:
    • EXAMPLE: Reel 1 NAM > Reel 2 NAM > Reel 3 NAM
    • EXAMPLE: If Reel 1 & 2 can fit completely onto a single LTO , but Reel 3 will not, please only include Reels 1 & 2.   Reel 3 should be placed on the next successive LTO tape.
    • Load reels of a single deliverable type successively onto tapes
    • If multiple reels can fit onto a single tape, load as many reels onto each LTO tape WITHOUT splitting or spanning any reels across tapes.


Barcode on LTO Tape 

An LTO barcode on the spine of the tape is required for use in LTO tape robots. There are specific requirements for barcodes (e.g. number of characters allowed and the format designation at the end). It’s not recommended that you use generic barcodes; these come in a variety of sizes and character counts, which makes it difficult for our robot barcode readers to scan/identify.

Use the label below as an example of what should be on the spine of the actual tape, NOT on the flat side. There must be a machine-readable barcode, with a three-letter show code.

 For LTO6:


 For LTO7:


 For LTO8:


Note: "LTO" should be replaced with three-letter show code, chosen by production.  The labels don’t have to be color coded.


Example LTO Tape: correctly barcoded on its spine, with the flat side blank.


Ordering/Generating LTO Barcodes:

Suggested LTO barcode stock is Avery 6577. It’s more durable and the adhesive is tacky but not hard to remove and reposition if necessary.  

These are good resources for LTO barcode formats, style numbers, creation and/or ordering:


Label on Exterior Case of the LTO Tape 

The following information should be included on a label that affixes to the outside case of the tape, NOT ON THE TAPE ITSELF.
