I know that if you place your playhead right on a cut and you press 'Q' twice, it will cut 1 frame and move the entire sequence to the left 1 by frame. Basically it takes 1 frame away.
I'm wondering if there is any shortcut that with a double click, instead of cutting 1 frame, it would add 1 frame and push the entire sequence to the right.
Basically the exact opposite of the 'Double Q' shortcut.
No, If you press Q twice it will cut 2 frames.
Shift+W will extend the clip to the left, i don't know of any shortcut that will also ripple.
