I was in the Etsy Forums discussions and someone mentioned a site where you can make free 30 second promo videos. So I decided to check it out and I have to say, I was very impressed with their setup. It was so easy to upload photos for your video and you can either upload your own music or use their wide selection of available music.
For a free subscription, you can make a limitless amount of 30 second vids (which is all you really need for a promo video). You can upgrade your account for what I thought was a nominal fee and have access to longer videos.
I've only made one video so far but the possibilities are endless as far as what you can create with a little time and planning.
Definitely visit: www.animoto.com and check it out.
