You can make a good book trailer yourself. The tools are cheap; the hard part is the decisions. This is the process we use in our studio, simplified for one author with a free weekend.
1. Decide what the trailer is for
A 20-second vertical video for TikTok and a 90-second trailer for your website are different films. Pick one place where it will live first, and design for that screen and that attention span.
2. Choose whose story the trailer tells
The most common mistake is trying to show the whole plot. Choose one character's point of view and one question the viewer should leave with. Write three different versions of that sentence and pick the strongest. Check it against the book: does it sell the book you actually wrote, in its real genre?
3. Write a paper edit
List 5 to 8 moments in order. For each, write who is in it, where, and what changes. Put your best line of dialogue near the end, and end on the question, never on the answer.
4. Cast your characters
Generate a reference portrait for each character and keep using it. Write down age, hair, clothes and one detail that makes them recognisable. Consistency is what separates a trailer from a slideshow.
5. Make the shots
Generate short clips of 3 to 6 seconds, one action each. Expect to make two or three takes per usable shot. Keep camera movement simple and make sure people look at what they are reacting to.
6. Sound first, then picture
Lay down the music and any lines first, then cut the pictures to them. Leave space around dialogue. Add subtitles: most people watch with the sound off.
7. Export for each platform
Export 9:16 for TikTok and Reels, 16:9 for YouTube and Amazon, and keep a 15-second version for ads.
When to hand it over
If you want characters who speak lines from your book, stay consistent across 20 shots and come with an original score, the time adds up to days. That is the part we do. You can start with a free trailer plan: three ideas for your book that you can also use for your own trailer.
