Once
            you import an EDL, you can edit any value except the event number. This
            includes:
         
         
            - The tape name for single or multiple
               events
            
- The audio patching information
            
- The transition duration and speed value
               of dissolves
            
- A cut to a dissolve or wipe
            
- The source and record timecodes of events
            
These tasks are described
            in the following sections. You can open multiple EDLs and copy and
            paste events between them. You can also use Auto Edit mode to quickly
            make changes to the entries you specify.
         
         NoteEDLs with references
               to a generated output tape (EDLs created with the Export EDL feature
               using the Output All or Output Generated option) are opened as read-only
               and cannot be edited. To edit a read-only EDL, save it to the filesystem
               with a different name.
