The technique is giant and knockout captions: for one line the caption itself becomes the picture. How it works: the caption box grows into a slab across the lower half of the frame, the words cut out of a cream block so the footage shows through the letters. It is right for: the loudest line of a talking-head video. The effect fires on the word that names it. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
