Animoto is really easy to use and is fun. As it says on their website "Create your own Animoto video now! Animoto is fast, free and shockingly easy. Pick a video style, add photos, choose a song. Post it. Send it. Share it." - This is all very true. And their App for the iPhone is simple and user friendly.
After being out with family the other day I wanted to create a quick video slideshow of the fun we had. In under 2 minutes (literally!) a 30 second video clip with music had been created, uploaded and e-mailed all from the palm of my hand (and an iPhone 4). It looked great too if I might add.
You can take pictures saved on your phone, arrange it in the order you like, add music to go along with your pictures and voila- you've 'animotode!' Check out these sample videos from the Animoto website. Today's technology is truly incredible.
