PresentationTube is a non-profit that has actually provided a totally free service to teachers for lots of years. That service is the ability to tape-record video presentations based upon PowerPoint files and PDFs. Just recently, PresentationTube launched a Chrome extension that lets you develop video lessons in your web browser..

PresentationTubes Chrome extension will let you record while talking over your PowerPoint slides or a PDF. You can tape-record with your web cam switched on or you can choose to just record your voice talking over your slides or PDF. While youre tape-recording you can make use of the screen, add text notes to the screen, and emphasize text on the screen..
When you have actually ended up tape-recording a presentation with PresentationTubes Chrome extension you can upload it straight to the PresentationTube website where you can then release it publicly or keep it unlisted. Just Like Google Docs, if you make your PresentationTube unlisted then only people who have the direct link to it can see it..
Applications for Education.
PresentationTubes Chrome extension could be a good one for anyone who is looking for a brand-new, simpler method to create video lessons based on their existing slides. Regrettably, it only works with PowerPoint or PDFs at this time. Ideally, in the future there will be support for Google Slides. In the meantime you can constantly download your Google Slides as PPT or PDF to utilize with PresentationTube.
