Creating a video narrator
I've been searching for tutorials and haven't been able to find any. I'm looking for examples and the process of inserting a video narrator into my powerpoint presentation where the person is speaking and the background is the ppt presentation itself. Of course the video would synch with the powerpoint content. I'm guessing that the video of the speaker would need to be done with a green screen in order to cut out their background so only the speaker show up on the ppowert?
