Quickest? maybe, but there's still a lot of steps.
Just choose your music, edit it to the correct length, choose the desired clips from all available footage, make your markers using the music track, pre-edit your footage to correct lengths, pre-plan the order of all your clips, select them in that order, then the software does the rest... except transitions, titles, fades, coluor correction, grading, and exporting.
I think "automate to sequence" is useful, I just think they're overselling it.
Really really over selling it.
