Use the Repeat tool
            to repeat individual frames, clips, or all frames in clips. 
         
         To repeat frames or clips:
         
         
            - With Video selected from the A/V Tools
               box, click Repeat.
               The Repeat controls appear.
                
- Select the item to be repeated in the
               Repeat Item box.
                  
                     
                        
                        
                        
                           | Select: | To repeat: |  
                           | Frame | The current frame in the selected clip. |  
                           | Clip | The selected clip. |  
                           | Frames in Clip | Each frame in the selected clip. (This can be used to
                              create a slow-motion or stop-action effect.) |  
 
 TipWhen you repeat with
                     the Frame option, the clip becomes virtual (no handles) so you can
                     trim it to any duration on the timeline.
                   
- Specify the number of repeats in the
               Repeat Number field. The item selected in the previous step will
               be repeated the number of times indicated in the Repeat Number field. 
            
- Select a clip and a destination.
               The result clip appears
                  in the selected destination.
