Error Code:

UndefinedError-MediaFormat (An error during parsing prevented the completion of MediaFormat analysis)

Error Message:

An error occurred when parsing ISO-BMFF: EditList with ctts not supported


A basic analysis failed due to a parsing error. This may be due to a corrupt file, a formal spec violation, or simply an unsupported variation of the format. One common error is related to the ISO-BMFF edit list. Netflix only accepts edit lists with one edit that matches the presentation delay introduced by the use of B-frames.


Re-encode/re-export a new deliverable created in accordance with our delivery specifications and attempt redelivery. Consult with your Netflix representative if the issue persists.
