‘Interoperable Master Format’ for file-based workflow

‘Interoperable Master Format’ Aims to Take Industry Into a File-based World http://bit.ly/bvF6Vk

A group working under the guidance of the Entertainment Technology Center at USC is trying to create specifications for an interoperable set of master files and associated metadata. This will help interchange and automate downstream distribution based on metadata carried in the file. The first draft of the specification is now done based on (no surprises) the MXF wrapper. (Not good for FCP fans, as Apple has no native support for MXF, without third party help).

Main new items: dynamic metadata for hinting pan-scan downstream and “Output Profile List”:

“The IMF is the source if you will, and the OPL would be an XML script that would tell a transcoder or any other downstream device how to set up for what an output is on the other side,” Lukk explained.

The intention is to bring this draft spec to SMPTE, but first, ETC@ USC is urging the industry to get involved. “We need industry feedback and input on the work that the group has done thus far,” said ETC CEO and executive director David Wertheimer. “Anyone who has interest in this topic should download the draft specification and provide feedback to the group.”
