I have a 15'34" video, with alot of clips, transition and narration. I need to trim the video by 34 seconds. I need to remove pieces in the middle, with out effecting the rest of the video. The extract tool seems to only allow me to extract one track at a time, and is destroying the transisions. How do I extract or remove just a portion of V1,V2,A1,A2 all at one time, as to close the gap and not effect the narration and the transisions?
