The Media Inspector displays adjustable parameters that define how an image or movie clip is displayed and composited in the project. These parameters define the source media’s essential properties, including frame rate, pixel aspect ratio, interlacing, and alpha channel parameters. There are also parameters that allow you to define source media’s end condition, reversal, cropping, and timing.
Open the Media list (the second list in the Project pane), select a media item, open the Inspector, then click the Media tab.
The Media Inspector shows adjustable parameters for and information about the selected item in the Media list. For information about adjusting source media parameters, see Source media controls in the Media Inspector.
