A system for streaming adaptive bitrate media content comprising: a reconciliation engine configured to evaluate metadata in a given manifest file of a plurality of manifest files generated for redundant copies of a given media asset, the metadata describing a condition of a given chunk of media content in one of the redundant copies of the given media asset and comprising a wellness score indicating the extent of any damage of the given chunk of media content, wherein each of the plurality of manifest files for the redundant copies of the given media asset are generated via separate media production pipelines to reference interchangeable chunks of media content for the given media asset; and a manifest modification function configured to modify the given manifest file for the given chunk of media content in response to the reconciliation engine detecting that the given chunk of media content is damaged based on the evaluation of the metadata and the wellness score associated with the given chunk of media content in the given manifest file, wherein the another copy of the given chunk of media content is at a lower bit rate to the originally referenced chunk; wherein the reconciliation engine further comprises a placeholder generator configured to generate a placeholder entry in the given manifest file for referencing the given chunk of media content in response to determining that the given chunk of media content is damaged, wherein the placeholder includes metadata that identifies the entry as a placeholder entry and whether the corresponding chunk of media content is missing or damaged, and wherein the placeholder preserves sequence alignment across redundant copies of media content even if one or more of such copies may contain a damaged or missing chunk, and wherein the reconciliation engine is configured to employ the placeholder entry to locate a corresponding manifest entry in another manifest file of the plurality of manifest files referencing another copy of the given chunk of media content. a reconciliation engine configured to evaluate metadata in a given manifest file of a plurality of manifest files generated for redundant copies of a given media asset, the metadata describing a condition of a given chunk of media content in one of the redundant copies of the given media asset and comprising a wellness score indicating the extent of any damage of the given chunk of media content, wherein each of the plurality of manifest files for the redundant copies of the given media asset are generated via separate media production pipelines to reference interchangeable chunks of media content for the given media asset; and a manifest modification function configured to modify the given manifest file for the given chunk of media content in response to the reconciliation engine detecting that the given chunk of media content is damaged based on the evaluation of the metadata and the wellness score associated with the given chunk of media content in the given manifest file, wherein the another copy of the given chunk of media content is at a lower bit rate to the originally referenced chunk; wherein the reconciliation engine further comprises a placeholder generator configured to generate a placeholder entry in the given manifest file for referencing the given chunk of media content in response to determining that the given chunk of media content is damaged, wherein the placeholder includes metadata that identifies the entry as a placeholder entry and whether the corresponding chunk of media content is missing or damaged, and wherein the placeholder preserves sequence alignment across redundant copies of media content even if one or more of such copies may contain a damaged or missing chunk, and wherein the reconciliation engine is configured to employ the placeholder entry to locate a corresponding manifest entry in another manifest file of the plurality of manifest files referencing another copy of the given chunk of media content.
