2. Now you have set up your rough cut. What you would actually want is the ability to fine tune. I would like to have a drag handle functionality that would be able to modify the cut position. It should be able to move to left or right. The limits of this operation are bound by the source videos. One can move to the left beyond the left video, but only up to the point that the right video has data. The same goes for the move towards right. At this moment you can never get this right with trimming or extending, especially not when there is an audio track to match it below. Hence I think this function would benefit every editor.
Like Phyllis wrote, Take a look at https://www.youtube.com/watch?v=voKxhxxUmok for that feature, please. Usually I use Rolling feature. If you want to perform a Rolling together to its Audio you have to use Group feature before. You can see how to Group to https://www.youtube.com/watch?v=PoJKEtaGXc4 Once a Group is created you have to select that Group and using Rolling feature you can drag the left or right edges contemporary for Video and Audio. I don't know if my explanation may be enough. IgorBeg
