Hi I've created a course in 2010 Powerpoint as I was told you can do that. Has anyone else used powerpoint and could give my some help on what I'm doing wrong.. I created my whole course 54 slides with naration over the top of each slide.. for some reason It works find and you can hear all the audio, but when I save it to video file I can't hear the audio.. Plus I can't actually save it in MP4. When I try to up load it in the window wmv file udemy says file upload failed.. Does anyone have any information that might help me... Thank you..
