Narrated Slideshow Lectures

Microsoft PowerPoint presentation

If you wish to have your narration alongside PowerPoint slides, you might consider recording slide show – a simple function in Microsoft PowerPoint.

It is also recommended to break the presentations into small sections (not more than 20 minutes for each section). Before uploading it, it is always a good idea to test it and make sure you save it properly.
