Extraneous Content is when additional, unnecessary content is included within the program. This may consist of large sections of black (with silence), slates, color bars, the SMPTE Leader, 2-pops, textless elements, ratings cards, FBI warnings, overlay branding, advertisements, or textless materials.
Extraneous content impacts the content quality of an asset as content unrelated to the program they wish to watch is served. There's a possibility that it is of creative intent, but is dependent upon the context of the scene. Any derivatives of the asset will also contain the extraneous content.
There are contextual clues that the extraneous content is creatively intended.
The file contains technical elements that are not creatively intended, and should not be apart of the final product (e.g. black with silence, slates, color bars, SMPTE Leader, 2 pops or text-less materials, etc).
How to Prevent:
Lock video tracks that are not being worked on in order to avoid cross-contaminating tracks. Review timeline to catch out of place or duplicated elements.
Redeliver a corrected video file with the extra content removed. You may encounter a VALIDATOR-1 error upon redelivery as the new file will have a different run-time to the original. Confirm that this is intentional to your Netflix representative via Backlot.
If the use of any of the items listed above is creative intent, then please communicate this fact to your Netflix representative via Backlot and the issue will be reviewed.
If you have also uploaded associated assets for an affected video (i.e. Secondary Audio or Timed Text) then these will need to be adjusted and redelivered as well to maintain sync. Please contact your Netflix representative and ask them to issue Redelivery Requests for those assets as well.
