I came across an interesting web based tool for developing recorded presentations.
PresentationTube offers a presentation recording software & online platform to help teachers, students and all business professionals record & share quality video tutorials!
The presentation recorder allows you to narrate and annotate PowerPoint slides, and synchronize a variety of visual media, including webcam, whiteboard, drawing board, Web browser, YouTube video, and screen activity.
The online platform uses the latest YouTube APIs technology and modern video uploader with progress bar to upload, process, and host the video presentation and combine it with scrollable slide navigator.
You can control the privacy level, share video presentation link or embed the video in any website or blog. The audience can move to the respective video content and control both the progress and length of video presentation.
