Book Trailer Maker
EchoWave is a free online book trailer maker that turns cover art, pull quotes and a handful of atmospheric images into a cinematic teaser readers stop scrolling for. Add narration from 63 AI voices, drop in your music, time animated text reveals to the beat, and close on an end card that tells readers where to buy. Export vertical for BookTok and Reels or widescreen for YouTube, straight from your browser.
Book Trailer Maker Features
EchoWave's book trailer maker is used by indie authors, publishers and book marketers around the world.
Made for authors
Sell the story before the first page
Template sites give every author the same three-slide trailer. EchoWave is a book trailer maker built on a full timeline editor, the same engine behind our trailer maker and promo video maker. Stack cover art, quote cards and narration on separate tracks, time every reveal to the music, and cut a teaser that feels like a film instead of a slideshow.

Trailer toolkit
Everything a book trailer needs, in one editor
Real editing tools underneath, so your trailer looks produced instead of templated.
-
Cover art, stock photos and AI-generated scenes
Upload your cover and pull b-roll from the built-in stock photo library, or generate atmospheric stills with the AI image tool, think fog-drowned forests for your thriller or candlelit ballrooms for your romantasy. Ken Burns pan and zoom adds slow drift to still images, the same trick our slideshow maker uses to make photos feel filmed.
-
Animated quote reveals
Pick from 81 text animations, 30 entrances, 25 exits and 26 loops, to bring your logline, review blurbs and pull quotes on screen with intent. If quote cards are the whole video, our quote video maker covers that format on its own.
-
AI narration in 63 voices
Paste your logline or a short script and generate voice over with the built-in text to speech tool. 63 natural voices span different ages, accents and tones, so a gravelly narrator can sell your noir while a brighter one handles the rom-com. Voice cloning is available as a paid feature if you want the narration in your own voice.
-
Music, beat sync and sound effects
Upload your licensed music track and EchoWave detects the beat, drawing a snap grid on the timeline so every cut and reveal lands on the downbeat. A categorized panel of 30 sound effect packs covers the whooshes and impacts trailers depend on. There is no stock music library, so bring a track you have rights to.
-
Cinematic transitions and color grading
Move between scenes with 56 transitions, then set the mood with brightness, contrast, saturation and hue controls plus grain and vignette for a shot-on-film feel. A cold desaturated grade reads thriller, warm and grainy reads literary fiction.
-
An end card that closes the sale
Finish with your title, author name, release date and retailers, and add a QR code image that phones can scan from the screen. Exported videos cannot contain clickable links, so put the store link in your caption or bio and let the end card do the reminding.
-
Captions for sound-off viewers
Most BookTok scrolling happens on mute. Auto-generate captions for your narration with word-level timing, style them with any of 176 caption presets, and translate them into 86 languages if your book sells in more than one market.
How it works
How to make a book trailer
From blank canvas to finished teaser in four steps, no editing experience needed.
-
Open the book trailer maker and pick a size
Start a free project at echowave.io, choose 9:16 for BookTok and Reels or 16:9 for YouTube, and upload your cover art, images and music. Everything runs in the browser, so there is nothing to install.
-
Build the scenes
Lead with your hook in the first two seconds, then cut three to five scenes of four to six seconds each. Mix cover shots, quote cards and atmospheric stills, and use keyframes or a drawn motion path where you want the camera to drift.
-
Add narration, music and sound
Generate AI voice over from your script, lay your music underneath, and snap cuts to the beat grid. A whoosh or impact from the sound effects panel on each transition makes the edit feel produced.
-
Preview and export
Preview the full trailer in your browser, then export a free HD MP4 (up to 720p) with a small removable EchoWave badge and a short branded end card. Paid plans remove the badge and raise quality to 1080p and up to 4K. Keep the BookTok cut under 30 seconds and let the YouTube version run to 60 or 90.

Book trailers for every kind of launch
-
BookTok teasers
Cut a 15 to 30 second vertical that opens on a trope hook like enemies to lovers or locked-room mystery, set in animated text over moody stills. Add captions, because most viewers watch muted.
-
Launch trailers for YouTube and your site
Run 60 to 90 seconds widescreen with fuller narration, more scenes and a longer end card. Embed it on your author site and pin it to your channel for launch week.
-
Cover reveals
Keyframe the cover sliding, scaling or tracing a drawn motion path into frame, timed to a hit in the music. Post a countdown version first with the cover hidden behind the blur region tool.
-
Audiobook previews
Pair a sample of your audiobook narration with one of 93 music visualizer styles so the audio has something to look at. An audiogram with the cover, a waveform and captions makes a strong Reels post.
-
Publisher catalogs and series promos
Build one trailer as a template with placeholders for cover, quote and buy line, then batch render up to 100 titles from a CSV upload. The REST API and MCP server can drive the same renders from your own tooling.
-
Classroom book trailer projects
Students build book report trailers in the browser on school Chromebooks and export them free in HD with a small EchoWave badge, nothing to install. Teachers can share one project structure and let each student swap in their book.

Book Trailer Maker FAQ
What is a book trailer?
A book trailer is a short video, usually 15 to 90 seconds, that teases a book's premise the way a film trailer teases a movie. It combines cover art and atmospheric imagery with music, on-screen text and often narration, ending with the title and where to buy. Authors post them on TikTok, Instagram, YouTube and their own sites.
Is EchoWave's book trailer maker free?
Yes. On the free plan you can upload media, build the trailer, generate AI narration, preview the result and export an HD MP4 (up to 720p) with a small removable EchoWave watermark badge and a short branded end card. Paid plans remove the badge and end card and raise export quality to 1080p and up to 4K, with 8K on Business, plus more formats.
How long should a book trailer be?
For BookTok, Reels and Shorts, 15 to 30 seconds performs best because attention drops fast in vertical feeds. On YouTube or your author site you can run 60 to 90 seconds. Inside the edit, aim for four to six seconds per scene, with a slightly longer open and close.
How much does a professional book trailer cost?
Production studios typically charge several hundred to a few thousand dollars for a stock-footage trailer, and live-action trailers with actors can run five figures. Making it yourself costs a fraction of that, and you can produce separate cuts for each platform instead of one fixed deliverable.
Do book trailers actually help sell books?
A trailer on its own rarely moves sales, but as social content it earns far more shares and watch time than a static cover post. The trailers that work open with a hook in the first two seconds, name the genre or trope quickly, and end with a clear title and buy prompt. Treat it as ad creative for BookTok and Reels rather than a one-off upload.
What should I put in a book trailer?
Open with your hook, the one line that sells the premise. Follow with three to five short scenes mixing atmospheric imagery, a strong pull quote or review blurb, and narration if you have it. Close with an end card showing the title, author, release date and retailers. Exported video cannot hold clickable links, so put the buy link in the post caption.
Can AI make my book trailer for me?
Parts of it, yes. In EchoWave you can generate scene imagery with the AI image tool, create narration from 63 AI voices, auto-caption the result, and ask Echo, the assistant inside the editor, to perform edits on command. It does not generate finished video clips from a text prompt, so you still assemble the trailer yourself on the timeline.
What music can I legally use in a book trailer?
Only music you own or have licensed. Trending pop songs are almost never cleared for promotional videos, even short ones. EchoWave does not include a stock music library, so source a track from a royalty-free library or a composer and upload it. The built-in panel of 30 categorized sound effect packs is included.
What size should a book trailer be for BookTok, Instagram and YouTube?
Use 9:16 vertical, 1080 by 1920, for TikTok, Reels and Shorts, 1:1 square for feed posts, and 16:9 widescreen for YouTube and website embeds. EchoWave resizes the same project between aspect ratios, so you can export all three cuts from one edit, adjusting the crop for each.
