I wanted to test Overlay Slides, one of the new features in Captivate 2019. For my example I used two videos, one (local) .mp4 and one YouTube video.

I added bookmarks, overlay markers, created some knowledge check questions and ‘normal’ content slides.

I can see this feature being used in language training: A video shows a conversation, questions are displayed throughout the video and, when answered incorrectly, learners are directed back to the applicable video segment.

Here is my example project.
