The Selected Clips section shows the clips you selected for import. The caption at the top of the section summarizes the total number of clips shown and how many of them were found and that are available to be imported. Clips displayed in black were found and will be imported. Clips displayed in red were not found in their original location. Clicking the Set File Location button finds the source files for clips that were not found. If you select one or more clips and click Skip This Clip, the clips are removed from the list and are not imported.
