1. A computer-implemented method comprising: displaying, by one or more computers, within a user interface of a digital media system, a bounded region representing at least a portion of a media item, the bounded region comprising a plurality of locations, the media item comprising a plurality of frames, wherein a location of the plurality of locations corresponds to at least one frame of the plurality of frames; displaying, within the user interface, a preview pane adjacent to the bounded region; detecting, by the one or more computers, a selection of a location of the plurality of locations in the bounded region, wherein the selected location corresponds to an associated frame of the plurality of frames; identifying, by the one or more computers, the associated frame to which the selected location corresponds; displaying, by the one or more computers, the associated frame within the bounded region in response to detecting the selection of the selected location; and displaying simultaneously within the preview pane the same frame that is displayed within the bounded region in response to detecting the selection of the selected location.
