I'm building an application that exports movies. The movies have one or more audio and video tracks. These tracks are pulled from other movies that contain media of varying compression schemes. When I export my composed movie using QTKit, I want to specify the encoding of each track. As it stands, I only see a way to specify the export format through the QTMovieExportType key passed to QTMovie writeToFile. How can I specify the encoding of each track?
