EdlMax can convert the tracks of an Omf to multiple Edls, or a single Edl.
Convert to Multiple Edls will create a set of Edls, each containing edit data from tracks of the Omf. Also see Saving Multiple Edls.
Convert to Single Edl will create a single Edl with one video track and up to four audio tracks.
Convert Omf to Edl Dialog presents options for assigning Omf tracks to Edl(s).
