Was hoping to collaborate with a friend on a Chupacabra teaser trailer... but it doesn't look like it's going to work out. Got some good ideas out of the process that I'll likely use, so it wasn't a complete bust. :)
So, since this is all about as speculative as you can get, I'm going to have to try and cobble something together myself. I've done it before, but it's been a long time. I did dip into my large library of stock video footage and found some stuff I think I can use, along with the recent Mexico footage I shot in September and just a month ago.
And, I sound some creative commons music I like that fits the mood I'm going for. Still sorting through my clips, but here's a little title sequence I'm playing with using some heartbeat and the music I found. Will add the credit for the musician who's work I used to the actual teaser trailer.
