MoveNote is an excellent free web and mobile app that allows you to create embeddable video presentations that include your video alongside a set of slides or pictures that you have pre-selected.
MoveNote is very easy to use. You first upload your PowerPoint slides or individual images and then you start recording your live video by explaining while you highlight and move through the slides.
Once completed you can save the composite recording and share it or embed on any website or blog.
MoveNote connects directly to your Dropbox, Google Drive or BOX account as well as with Gmail and Microsoft email clients.
Free to use.
