"Mozilla's Popcorn Maker is a free tool for crafting videos that incorporate images, remixed video clips, links, and social feeds. It can take some time to get the hang of all of the features of Popcorn Maker, but it is a powerful tool. Kevin Hodgson recently published a nice screencast that walks you through the process of using Mozilla's Popcorn Maker."

This tool will take me a while to learn, but this screencast and the PopCorn Maker Tutorial at https://popcorn.webmaker.org/ will give you lots of ideas and instructions.
