I seem to make lots of small mistakes when assembling my videos quickly, overlaps extra clips etc. Is there an editing setting that acts as if the clips were dominoes on a table? Like an added clip would push the clip in front of it not go over the top, kind of like ripple edit but in both directions.This would allow quick assembly then I could go back and do fades, dissolves fx etc. Not sure of my description but would appreciate any help.
