video edits; a different technical version; etc. Most important, the MAM content delivery needs to fit seamlessly into an IMF specification so that the package that is delivered takes advan- tage of these “logical versions,” supporting a flexible mechanism to automatically select the proper components to deliver (video, audio sub- titles, attachments, XML, etc.) in the correct order and with the proper media transformations required for a particular reception site. To maxi- mize monetization of the media, new Media Asset Management Systems need to be able to support: • • • IMF Media Import - Processing the IMF pack- age and creating assets that can be physical or virtual, preserving and extending the IMF Composition Play List without media duplica- tion. Content Enrichment - By creating new ver- sions establishing logical references to the Master and taking advantage of the logical references to the media from the Master(s). IMF Delivery not limited by the original IMF received packages - Ready to generate new compliant pack- ages with any compatible com- bination of the components for a specific Title: Video (SDR, HRD, different aspect ratios), Audio Languages, Subtitles, attach- ments, XML, etc. An effective IMF MAM solution must be focused on a specific product: a collection of media files that com- prise a feature, an episode, a trailer, etc. A MAM solution that best lever- ages the IMF methodologies employs the concept that the MAM does not need to archive the intact IMF pack- ages as they are received. IMF is a vehicle to deliver and interpret different versions of that media asset. To get the maximum benefits of these efficiencies, IMF end-to-end workflows must fully support the IMF packages at all levels of the asset management tools and workflows. Beware of ‘IMF-ish’ solutions that store and man- age the media using “IMF labels” without actu- ally processing the assets and maximizing the advantages of this new content management and exchange methodology. It is easy to put new IMF labels on a screen--true IMF compliant MAMs ingest newly acquired media into Component Play Lists (CPLs) and use IMF markers for media file annotations, making version “cut and splice edits” a simple transcoder task. IMF compliant MAMs require a title concentric design, where a title encompasses much more than it has in the past--a key requirement of IMF compliant MAMs is the support for multiple Master versions co-existing within the same title. New version workflows depending on your company’s business rules, can automatically manage slate insertion, pre/mid/post rolls, and any formatting of the video content including bars, audio tones, blacks, etc. that might be needed to support your client’s destinations, with or without an offline editor. The key feature for an IMF compliant MAM is to be able to manage new version assembly or control the import of the EDL from an editor to identify new fragments and create a logical asset referencing the Master in the MAM. To implement a true end-to-end IMF workflow, the MAM needs to be able to handle the relationships between different versions of the same title to represent the product that is created incrementally through the reception of the IMF packages, all their com- ponents and any supplemental packages that are received. IMF compliant MAMs can significantly reduce storage requirements through maximizing the use of logical versions. And by employing the IMF Broadcast Beat Magazine • www.broadcastbeat.com • 77
