DaVinci Resolve has limited support for importing EDLs. I think its limited support is a good convention to replicate in Ftrack. Basically, when you import a clip into Resolve (a single movie), you can also import an EDL. The EDL is only used to determine where the cut points are; the actual clip filenames in the EDL aren't used. Also, the EDL must be very simple - a single track. The same functionality would be useful when uploading a long video to Ftrack, to provide cut points to jump between.
A further improvement would be associating those cut points to Ftrack entities, for example if each cut point represents a "shot", being able to associate the long movie with the actual Ftrack shots. But I can see that being difficult.
