Prompt templates are written from how generation models usually behave and have not yet been verified one by one with real generations. “Common pitfalls” are judgment from experience, not official limits.

When to use it

Giving background, inner monologue, documentaries and explainers, tying loose images together.

Prompt template

(for a voice tool) voice-over, young female voice, slow pace, calm with a touch of nostalgia, pauses between sentences: 'That summer, I left home for the first time. On the platform, my mother never waved.'

The technique comes first, followed by the scene, action, performance and duration. Paste it straight into a video model and swap in your own characters and plot.

(For a voice tool) Voice-over, a man in his twenties, speaking slowly, calm with a trace of guilt, a one-second pause between lines: “That New Year's Eve, I didn't tell my family I'd lost my job. I just said work was busy and I wasn't coming home this year.” (On screen: he walks alone down a snowy street, without saying a word.)

Common pitfalls

The voice-over repeats what you can already see on screen.
Too much voice-over leaves the picture no room to breathe.
The voice's emotion doesn't match the picture.

Parameter tips

The voice-over says what the picture can't (thoughts, the past, outcomes); leave 1 s between lines.
