Limit the Number of Edits in Your Sequence
Different EDL formats allow for different numbers of edits in your sequence. If your
sequence has more than the allowed number of edits for the selected EDL format,
Final Cut Pro automatically creates additional EDLs, depending on the number of
total events.
The following are the maximum number of edits, or events, allowed in various
EDL formats.
 CMX 340, CMX 3600, and Sony 5000: 999
 Sony 9100 and GVG 4 Plus: 9999
