I get a lot of emails from various organizations about all sorts of topics related to talent development.
Here is a free webinar on keeping learners engaged with video.
It's being put on by TechSmith, which makes the Camtasia video-editing software, so it is part of their marketing plan; however, they can often be some good nuggets of info to discover.
I like Camtasia; it's easy to use. I used it for promoting a Design Thinking workshop back in November led by our own Marvin DeJean.
