Adds blocks that pile up on a talking-head video as each amount is said, so an accumulation (savings, hours, sign-ups) is seen growing. Timed to the words they say, on their own footage, with their sound kept; 16:9, 9:16, 1:1 or 4:5. Renders locally with Chrome and ffmpeg: no video model, no key and no cost. Use when someone describes something building up over time (savings each month, hours each week).
