How to make a book trailer from the story itself
Give Vizard Agent the book's premise and the hook you want to open on. Vizard Agent checks the book's details, casts a narrator against the genre, generates a scene for every beat of the story, and cuts the trailer to the narration's own word timings.
What do you type into Vizard Agent?
Write the hook out and let the rest follow. Vizard Agent uses the hook's register to cast the narrator and set the grade, then builds a scene for each beat of the premise you describe. The hook is the only line most viewers will hear, so it's worth writing carefully.
Prompt
What does Vizard Agent actually do?
A trailer built from the cover is a graphic; one built from the story is a film. This one dramatises the premise in generated scenes, so the script is written as beats rather than as a blurb, and the cut follows the narration's word timings. The end card is reviewed composited over the closing shot, not on its own. In the session behind this article it:
- Checked the book's details and the available generation tools, then searched for a narrator three ways (dramatic, thriller trailer, female cinematic) before choosing.
- Generated the narration, transcribed it for word-accurate timings, and downloaded candidate stock footage and cinematic mystery music.
- Generated the scene visuals in two batches and inspected them all as a contact sheet.
- Generated sound effects for the key dramatic beats, measured every audio stem's loudness and tested smooth camera zoom rendering before committing to it across thirteen shots.
- Composited the end screen over the closing shot, reviewed it and rebuilt it twice in a bolder typeface.
- Mixed the music ducked under the voice, regenerated the captions at a size that wrapped correctly and re-rendered: 58.5 seconds at 1080x1920.
When does this not work well?
Dramatising a book in generated scenes means inventing images the author never wrote. They're an interpretation, not the book's own imagery, and readers notice, so settle how closely they should match the text before publishing. Don't depict real people, and if you aren't the author, check what promotion the publisher permits. Faces are the weak point, so keep shots atmospheric.
Common questions
Do I need any images? No. Vizard Agent generates every one of the scenes from the premise you describe to it.
How long should a book trailer be? Forty-five to sixty seconds. Long enough for the premise, short enough to keep it a hook.
Will the scenes match the book? They interpret the premise. Correct any that read wrong and Vizard Agent regenerates them.
