This question has been asked before (back in 2006)! But I haven't found a solution to it since...
I need to sync many video and audio clips. I need to mark the sync points (e.g. clapper board) in the clip itself and then line them all up. Doing it in the trimmer isn't particularly helpful because I often need to line up the clips visually (and by listening) on the timeline and then mark the sync point in the clip in question itself.
How can I do this - without having to open each clip in the trimmer?
