A book trailer fails more often from a weak script than from weak visuals. The good news: once you have a working structure, you can reuse it for every book, every platform and every length. This guide gives you ready-to-adapt script templates for fiction and nonfiction, plus fill-in lines, timing notes and genre-specific tips so you can draft a trailer in under an hour.
Before you write: three decisions
Scripts go faster when you decide these first:
- Platform and length. Social feeds: 20–45 seconds (about 45–100 spoken words). Website or Amazon author page: up to 60–90 seconds.
- Voice. Narrated (you or an AI voice), on-screen text only, or a mix. Narration needs shorter sentences; text-only trailers can use punchier fragments.
- One job for the last frame. "Available on Amazon", "Pre-order link in bio", "Free sample on my site" — pick one call to action and stick to it.
If you need the full production walkthrough after the script is done, see How to Make a Book Trailer.
Template A — Classic fiction trailer (30–45 seconds)
Use this for most novels: romance, thriller, fantasy, mystery, literary. Timing assumes ~140 words per minute of narration.
| Beat | Time | Script line (fill in) |
|---|---|---|
| Hook | 0–3 s | "[One sentence that states a rule, a stake, or a forbidden desire.]" |
| Who / where | 3–10 s | "[Name or role] lives in [place / situation]. [One detail that makes them interesting.]" |
| Inciting problem | 10–22 s | "Then [event]. Suddenly [what they want] depends on [what they must risk]." |
| Escalation | 22–35 s | "But [antagonist / twist / cost]. And [clock or consequence]." |
| Cliffhanger | 35–40 s | "[Question the book answers — never the answer.]" |
| Title + CTA | last 5 s | On screen: cover, title, author. Voice or text: "Available now [where]." |
Filled example (fantasy):
- "Every spell in Veyra costs a memory. She has cast thousands."
- "Lira is the last court mage who still refuses to forget."
- "When the queen orders her to erase a rebellion from history, the price is her mother's face."
- "But the rebels know a secret Lira was never meant to keep — and the queen is already rewriting her tomorrow."
- "How many memories will she trade for the truth?"
- Title card: Ash of Names — Available on Amazon.
Template B — Trope-forward romance (20–30 seconds)
Romance readers often decide in seconds based on tropes. Lead with them, then one emotional beat.
- 0–2 s (on-screen text): "[Trope] · [Trope] · [Trope]"
- 2–8 s: "[She / He] agreed to [fake dating / one last job / a marriage of convenience]."
- 8–18 s: "Then [the moment feelings get real]. And [the reason it should never work]."
- 18–24 s: "[One line of dialogue or thought that sells the chemistry.]"
- Last frame: Cover + "Read now — link in bio."
Filled example: On-screen: "Grumpy/sunshine · Forced proximity · Small town." Narration: "She rented the cabin next door for three quiet weeks. He runs the only hardware store for forty miles — and he has opinions about her DIY skills. One broken porch rail later, neither of them is quiet."
Template C — Thriller / mystery countdown (30–40 seconds)
Thrillers sell urgency. Put a clock or a body count early.
- Hook: "By sunrise, [number] people will know the truth. Only one will survive it."
- Setup: "[Protagonist role] finds [evidence / body / message] in [ordinary place]."
- Complication: "The official story says [lie]. The evidence says [worse truth]."
- Pressure: "[Antagonist] is already [closing in / erasing proof / watching]."
- Question: "Who do you trust when everyone has a motive?"
- CTA: Title + "Out now."
Keep character names to two maximum. Specific places and objects ("blueberry pie", "locker 214") beat vague danger every time.
Template D — Nonfiction problem → payoff (30–45 seconds)
Nonfiction trailers should teach one useful idea and promise more, not summarise the whole book.
- Problem (0–5 s): "Most [audience] try to [common approach] — and wonder why nothing sticks."
- Surprising insight (5–15 s): "The real bottleneck is not [what people blame]. It is [your book's core idea]."
- One concrete takeaway (15–28 s): "Here is the first shift: [one actionable tip the viewer can use today]."
- Scope (28–38 s): "Inside the book: [3 specific chapters or tools], without [jargon / fluff / 400-page theory]."
- CTA: Cover + "Get the book — [link / Amazon / site]."
Self-help, business, memoir-with-lessons and how-to titles all fit this frame. Memoir that is primarily story can use Template A instead.
Template E — Series / episodic hook (15–25 seconds)
If you are posting a multi-part series (the format short-form platforms reward), each episode needs a colder open and a hotter cliffhanger.
- Cold open: Jump into a mid-scene line — no "welcome back".
- One beat only: Advance a single moment; do not summarise the book.
- Cliffhanger line: End on a decision, reveal or threat.
- Series label: On-screen "Ep. 3" plus the same title card style every time.
This is the pattern automated tools like xBookvideo use when they split a book into narrated episodes: hook-first narration, matching visuals, subtitles, and a consistent end card so viewers recognise the next part.
Fill-in phrase bank
When you are stuck, steal the shape of these lines and swap the nouns:
- "She only needed [X] for [Y]. She got [Z] instead."
- "In this [world / town / company], [rule]. Breaking it costs [price]."
- "Everyone thinks [lie]. Only [character] knows [truth]."
- "If you like [comp title vibe] with [extra twist], keep watching."
- "The book for anyone who has ever [specific emotion / situation]."

Timing, word count and formatting tips
- Word budget: ~2.3 words per second of comfortable narration. A 40-second voice-over is roughly 90 words. Write long, then cut.
- Read aloud: if you run out of breath mid-sentence, split it.
- On-screen text: max 6–8 words per frame; large type; high contrast.
- Names: introduce at most two characters in a trailer under a minute.
- Never spoil: stop when the question is clear. The book answers it.
- Export checklist: vertical 9:16, burned-in captions, title card last, no platform watermarks if you will cross-post.
A 20-minute scripting workflow
- Write 10 hook candidates in five minutes. Circle the one a stranger could repeat.
- Pick Template A–E and fill every bracketed line without editing.
- Read the draft out loud against a phone timer. Cut to fit your target length.
- Mark visual notes in brackets after each beat: [cover], [stormy harbour], [two silhouettes].
- Produce three openings if this is for ads or a launch — same middle and end, different first lines — and keep the one that holds watch time.

Common script mistakes
- Opening with your name or "my new book is about…" instead of a hook.
- Summarising the whole plot in sixty seconds.
- Naming five characters and three subplots.
- Ending on a bland "available now" with no unanswered question before it.
- Copying a movie trailer's tone when your book is cozy or literary — match reader expectation.
- Writing for silent viewers without on-screen text (most social video starts muted).
FAQ
Do I need different scripts for TikTok, Reels and Shorts?
Usually no. One strong vertical cut works on all three. You may tweak the first line or caption per platform, but the script body can stay the same.
Should I write the script before or after choosing visuals?
Script first. Visuals are easier to find or generate once you know each beat. Starting with pretty clips often produces a mood board, not a trailer.
Can AI write my trailer script?
It can draft options, but you should edit hard: AI often summarises instead of hooking, and it may invent plot points. Keep your voice and your actual stakes.
How many trailers do I need?
One main trailer for the launch page is enough. For social, plan a short series — Template E — so you have weeks of posts from the same book.
