DELIVER



NETFLIX Delivery Requirements

Netflix requires content to be delivered according to its guidelines in version 8.1.

Netflix requires specific mandatory metadata to be delivered with the programme. This metadata is outlined in the Metadata Template. Due to the complex delivery requirements, producers often use specialised companies for delivery to Video on Demand platforms such as Netflix.

Anyone distributing to Netflix should be aware that these guidelines are legally binding.

Netflix summarises its policies as follows:

Files may not have any of the following: test pattern bars (bars and tone), VITC time code, advertisements, production slates, ratings cards, FBI-warning signs, placards, overlay branding, website links, commercial bumpers, promotional bugs, informational bugs and segment previews or recaps.

All files must contain the main program contain a minimum of 1 frame and a maximum of 1 second of black at the beginning and end of the program). If the source content contains commercial blacks, each commercial black segment must be trimmed down to 2 seconds or less, there are no exceptions to these requirements.

Netflix requires a non-subtitled version of the content. Netflix defines "not subtitled" as a presence of major titles, credits, narrative text, spatial overlays and other supportive / creative text but requires the absences of burned-in subtitles, regardless of the language in the primary video.

Netflix also requires uninterrupted versions for Follow-Content. Bumpers, previews and summaries of segments or episodes are to be removed. Depending on the delivery, there are a range of formats that Netflix supports:

  • SD / HD sources: Netflix accepts MPEG-2 transport stream or iTunes® package ProRes files.
  • All ProRes 422 HQ files must comply with the iTunes package specifications.
  • HD and 2K sources can also be supplied as IMF Application 2 Extended files.
  • 4K / UHD sources: Netflix accepted IMF Application 2 Extended files.

Programmes cannot be supplied as multi-part files, i.e. when a track is 90 minutes long, a single file with 90 minutes should be delivered. Two (2) files of 45 minutes duration will not be accepted. 

Netflix requires that files are delivered in their native frame rates. Netflix defines this as the frame rate which the material was originally recorded or cut at. Whenever it is an original movie, Netflix requires the native film frame rate (either 23.976p or 25p). This is often the frame rate used for tape archive storage and delivery to stations (usually 29,97i df or 25i). No 3:2 pull-down flags allowed.

Netflix requires that files are delivered in their original aspect ratio. Netflix does not accept 4x3 version if a 16x9 version was originally created.

Increasing the resolution of content is not allowed. No SD sources may be used for the preparation of HD deliveries. 4K UHD video must be from an actual 4K UHD source and maintain 4K resolution during the entire post-production process.

The source material must have a quality that corresponds to or exceeds the chosen Specification. Example: 15 Mbit Long GOP MPEG2 HD must not be used for the production of 80 Mbit I-frame HD MPEG2 or ProRes HQ.

The source material has to be uncensored.

Short form content with durations under 11 minutes must be combined to create longer episodes.

The distributor or facilities house should deliver the source material to the Netflix content partner portal (Netflix The Backlot Source Delivery UI). Alternatively an API (Application Programming Interface) integration is available that can be used to interface with the asset management system of a distributor or facilities house.

Due to the huge catalogue and use of acquisitions as well as Netflix Original commissions, it’s vital to refer to the technical delivery requirements and to work with a post production house that is accredited to deliver to Netflix.
