12.6 PLAY LIST EDLS
On exiting a session, 3Play™ creates an EDL (Edit Decision List) file for each existing playlist.
These files can be used to reconstitute a playlist in NLE (non-linear editing) applications with EDL
file import support.
3Play’s EDL files are created on the master Session Drive for the session, in a folder located at
drivename:\Media\EDL\session name\.
