The Advanced Media Workflow Association has formally approved the Advanced Authoring Format Effects Protocol AS-05. The AAF Effects Protocol allows greater interoperability between video post-production systems by defining a set of new effects beyond those in the AAF Edit Protocol AS-01. There is often a need to transfer effects information between systems for example from offline editing to finishing says Brad Gilmer the AMWA's executive director. AS-05 provides a means to transfer data in an open and interoperable form between systems from different vendors. Using the AAF Object model the specification supports the exchange of metadata concerning title opacity and color effects. Title data includes the position font and color of video titles. The color metadata is based upon the American Society of Cinematographers Color Decision List format which defines a set of parameters for interchanging basic color correction information. The specification can be downloaded from the AMWA web site at www.amwa.tv.
