PresentationTube is a non-profit that has actually provided a totally free service to instructors for several years. That service is the capability to tape video discussions based upon 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 record while discussing your PowerPoint slides or a PDF. You can tape-record with your cam switched on or you can pick to simply tape your voice discussing your slides or PDF. While youre tape-recording you can draw on the screen, include text notes to the screen, and highlight text on the screen..
When you have completed recording a presentation with PresentationTubes Chrome extension you can submit it straight to the PresentationTube website where you can then release it publicly or keep it unlisted. Much like Google Docs, if you make your PresentationTube unlisted then just people who have the direct link to it can view it..
Applications for Education.
PresentationTubes Chrome extension might be a great one for anyone who is searching for a new, easier method to produce video lessons based on their existing slides. It just works with PowerPoint or PDFs at this time. Hopefully, 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 use with PresentationTube.
