PresentationTube is a non-profit that has provided a complimentary service to teachers for several years. That service is the capability to record video presentations based on PowerPoint files and PDFs. Recently, PresentationTube released a Chrome extension that lets you develop video lessons in your web internet browser..

PresentationTubes Chrome extension will let you tape while talking over your PowerPoint slides or a PDF. You can tape with your web cam switched on or you can pick to simply tape-record your voice discussing your slides or PDF. While youre taping you can make use of the screen, include text notes to the screen, and highlight text on the screen..
When you have completed taping a presentation with PresentationTubes Chrome extension you can submit it straight to the PresentationTube site where you can then release it openly or keep it unlisted. Similar To Google Docs, if you make your PresentationTube unlisted then only people who have the direct link to it can view it..
Applications for Education.
PresentationTubes Chrome extension might be a great one for anybody who is trying to find a new, much easier method to produce video lessons based on their existing slides. Sadly, it only deals with PowerPoint or PDFs at this time. Ideally, in the future there will be assistance for Google Slides. In the meantime you can constantly download your Google Slides as PPT or PDF to utilize with PresentationTube.
