Animoto | Social media kitbag |
This tool - which has a free version limited to a 30 second video - enables you to create video slideshows from photos and video clips and then share or embed in your website. So this could be good for illustrating multimedia in stories.

This from the site's blurb: "Video Slideshow Maker with Music Animoto turns your photos and video clips into professional video slideshows in minutes. Fast, free and shockingly simple - we make awesome easy."
