These two services allow you to add questions and comments to an online video which cause the watcher to pause and respond before they continue. This is a wonderful method to increase engagement in video delivery.
The video below discusses the similarities and differences between the two services. One feature about Zaption that it does not mention is the ability to "Present" your video to the class. Using this method, you can engage in a Kahoot!-like experience where students all respond to the video questions using their laptop or mobile device.
Whichever tool you choose, online videos just got a whole lot more interesting!
