Well, an “export” is not usually used if there is a “roundtrip” involved
that includes unused clips and any handles.
To do a round trip, one can send the Library file in it’s entirety.
And then the other user can send back a project file / event file that would fit right in to the original Library of Events.
Are you saying that you want to send someone a set of clips that are 2 minutes all together
and have that person send back one of them with new start and stop times?
