Hi Rupert,
Simply drag your QT movie file onto the FrameLink application icon. This will mount a disk image on your desktop that has the DPX files.
To create a QT movie from a series of DPXs, double-click on the FrameLink application and fill in the preferences about the type of movie you’re creating and an empty disk image will show up on the desktop with a QT movie of the same filename. Just copy the DPX files into the disk image and the QT movie will update itself.
