Camtasia
Many may not know that you can export a Camtasia video to GIF. That may be cool, but why would you do that? I probably wouldn't want to do this for full-length videos with audio. The most practical solution would be to use these short animated GIFs on help documents, static web pages, or PDFs.
Imagine a help document with text explaining the step, and instead of just a static screenshot, you see an animated GIF showing that step in the process. You could create an animated GIF to be easily shared and played on a social media channel. Most GIFs play automatically without you having to press play.
