The technique is voice-over written to the cut: the voice ends when the picture does. How it works: write the voice-over to fit this 15-second animation, one line per shot, about 2.2 words per second, the last two seconds left free for the end card. It is right for: ads with a fixed slot of 15 or 30 seconds. A line typed into a voice tool without the timings is a guess: one creator shows a six-second voice-over delivered for a thirty-second slot. This order suits a fixed length. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
