Yesterday morning someone on Twitter asked me for a recommendation for making a whiteboard video in a web browser without using Seesaw. (By the way, here's how to do it Seesaw). My suggestion was to try using Screencastify to record over the free drawing space provided by Google's online version of Jamboard. The online version of Jamboard is free unlike the physical product of the same name that Google sells. Here's a video of how that process works.
One of the benefits of using Jamboard for this kind of video is that when you are done you can share the Jamboard images with your students. You could even share the Jamboard via Google Classroom so that students have a copy of the process that you demonstrated while making your video.
