Missing Format Black
"Missing Format Black" refers to an asset missing the required 1 second of black and silence before and after program content on the primary video asset..
Missing format black impacts the Technical and Content Quality of an asset. This does not adhere to the Netflix Delivery Specification. As some streams delivered to customers need time to buffer, some portions of content may be lost due to an absence of black at the head and tail of the file. For ident-free workflows, the additional black is required to accommodate a seamless stitching of the Netflix ident within the Netflix internal pipeline.
One second of black and silence before and after program content is not included in the file, or black and silence is shorter than the required one second duration.
How to Prevent:
Review and adhere to the Netflix Delivery Specifications.
One second of black and silence must be added to the head and tail of the file for redelivery.
