IMF is an interchange format designed for post-production/studios versioning requirements. It reduces storage required for multi-version projects but also provides for a standard way of exchanging metadata between companies.
Annie Chang covers the history briefly of IMF showing what it was aiming to achieve. IMF has been standardised through SMPTE as ST 2067 and has gained traction within the industry hence the continued interest in extending the standard. As with all modern standards, this has been created to be extensible, so Annie gives details on what is being added to it and where these endeavours have got to.
