Animoto is a very, very simple video creation site (and app). You can use it to make short (30-second) videos with photos and text.
It takes only a few minutes. For this one, I used music and a couple of photos from Animoto’s library and a few photos of my own.
When you choose a template, it will ask you if you want to purchase it or make a 30-second video for free. Start with the free.
