You can modify the alignment of each strip anytime you want. Click the right mouse on the strip you want to change, and select command Modify strip origin. You can change the origin with the mouse (by aligning the new origin to existing snaps, such as tiles, objects, corners, …) or typing the exact offset with the numeric fields (remember that you can switch between them using Tab keyboard button). When typing it is recommended not to move the mouse, as moving it will cause the fields values to change. Press Enter keyboard button when finished typing.
