Line Carry Transition

An accent underline is drawn under shot A's title, rests a beat, then keeps running right out of the frame; the camera follows the line 960px (2s power2.inOut — during the pan the line grows exactly as far as the camera moves, so the pen tip stays pinned at screen x≈640, never leaving the frame and never falling behind), then the line turns hard right angles up, right, down and left to enclose a 560×330 frame; on the frame the frame closes the pen tip disappears and shot B's content fades in inside it — no cut anywhere, one line stitches the two shots together
