## Watch out

- A text-to-speech voice-over has a known script: lay it on the pauses in the audio instead of transcribing it. (measured; House rule)

## Prompts

### Any chat model

```
Write a shot-by-shot outline for a short video about [your product], for [your audience]. Use the b-roll with voice-over pattern: the words explain, the images prove. A text-to-speech voice-over has a known script: lay it on the pauses in the audio instead of transcribing it. How it works: a voice-over carries the script while each line gets its own shot of the thing it talks about. Plain spoken language, no hashtags, no emoji. Tell me which one you would post first and why, in one line.
