I've just recently made a book trailer for my new release. I have other book trailers for my previous series, and I wanted to continue with them. They had cost me $100 to get made, and recently the price has gone up. So, I thought I'd try it myself. I made it using stock photos and pictures I took in Vegas. I am a member of a service since I use them for blogging too. I used iMovie to edit it all. Took about 3 days.
Book Trailers have gone through some trends too in the last few years. They started out with more photos, music and the story told as a sales blurb. Then, it moved to movie stock clips and voice overs. Some book trailers have gotten to be like small movies. I made mine more like the other book trailers I have. I've included links to the one I made, and the other book trailers I had created for my books.
To note, I also made a book trailer for my children's book, and it has a little over 1,000 hits after 10 years online. I give the link to bloggers, have it posted on my blog, and on Goodreads. It's a selling tool, to help people decide if they want to read the book. I've always thought of them like the blurb on the back of your book> You're trying to get people interested in reading it.
This is the book trailer I made for my recent release: Never Date A Vampire.
Book Trailers made by Apex Reviews for my other novellas:
Style with photos, music, word narration
Style with photos, music, and audio narration with words
Children's Book trailer: I made this in 2009. So, it's of an older style, but it works. I took some of the pictures and put them through different filters. I also used the artwork from the cover and inside the book. I own the artwork that I commissioned for the book.
