well what i do is to make a “bin unused” in the project pane. then go to “edit” “remove unused” then hit undo and all the unused clips will be highlighted. then drag the highlighted clips to “bin unused”. now you have a bin used and a bid unused.
i tried sync lock and it worked fine.
4 video tracks and 1 audio track.
shift-click sync lock in both video and audio tracks
click sync lock for the track you want to extract audio or video.
mark your in and out.
hit extract.
You could select a clip in the timeline and hit “Match Frame”. That will call up the master clip in the Source monitor, then with audio only selected in the timeline, hit “Overwrite”.
i found what you are talking about frustrating also…so i made a default folder named “HOLDING TANK” and i know that always premiere will place my .mov’s in the same place. it’s an ok work-around for me.
