I’ve had a few emails, so let me say briefly:
Book trailers are a fairly new approach to advertising forthcoming novels. There are a lot of them out there, all you have to do is search on Google Video or YouTube. The quality is pretty uneven. Some of the best ones are (as is to be expected) the professional book trailers done by, or paid for by, publishers.
A couple I like a lot:
Bennett’s Portrait of an Unknown Woman
I’m not so enthusiastic about the trailer for Chabon’s The Yiddish Policemen’s Union, but that’s just my taste.
Generally I prefer book trailers that are collage-like with music/audio backgrounds. The ones I’ve seen that are live action with dialog … well, let’s just say that they don’t work for me. At all.
Brenda Coulter has a post about how she created her trailer for A Season of Forgiveness. If I have time I’ll put together a summary of how I did mine. Brenda works in the world of Windows and I’m on a Mac, so my approach was different.
If you look at book trailers on YouTube, you’ll see that some of them aren’t too fussy about where they get their images and/or music and audio. Most do take copyright seriously (as we are, after all, authors and make our living from royalties), but a few don’t. I bought the rights to some of the royalty-free images I used, but most of them were made available for use under the Creative Commons license. Ditto for the music. Full credits at the end of the Tied to the Tracks trailer, in case anybody is interested.
In a comment, Anne reminded me about Cory Doctorow‘s work on behalf of Creative Commons and the principles behind it. Cory releases the full texts of his novels in electronic format on the day the hard copy is released for sale in bookstores. Sometime I’ll have to find out how he and his publisher worked out the details of this.
Finally, a note: if you have time to go over to YouTube to have a look at the Tied to the Tracks trailer, please do. And while you are there, if you’d care to rate the trailer, that would be kind of you. The trolls are already out and active, in force.
