The introductions of Ultra High-Def (UHD) and high dynamic range (HDR) distribution platforms represent a major force that’s helping to drive adoption and implementation of the Interoperable Master Format (IMF), but challenges to wider IMF adoption remain, according to Eric King, Deluxe Entertainment senior director of technical operations.
With UHD, “obviously the impact is in terms of file size” because, “all other things being held constant, you have four times as many pixels to deliver, so obviously your payload would increase” similarly, King told the Media & Entertainment Services Alliance (MESA) in a phone interview.
Other factors that are driving IMF adoption include delivery specifications requiring Interoperable Master Packages (IMPs) as deliverables and the rapid growth of localized international iterations for over-the-top (OTT), video on demand (VoD) and subscription video on demand (SVoD), King said.
IMF first started being developed back in about 2007 or 2008, evolving out of the Digital Cinema Package (DCP) architecture, he pointed out. The SMPTE standard was designed to streamline the interchange and automated creation of downstream distribution packages, making it cheaper, easier and faster for content to be distributed globally. IMF stores a single master set of file-based elements that can be assembled using multiple composition play lists (also known as “recipes”).
