Moyea PPT to Video Converter - PowerPoint to Video
Full user review
"Nice looking interface and very easy to use."
Does the job in record time in a few clicks. None of the free converters I tried worked. And some of the other converters were three or more times the cost of this one.
It'll set you back 50 bucks to rid yourself of the logo. But, if you'll be using it regularly, it'll eventually be worth the money. Or you can grant them free advertising by sporting the logo in all your presentations.
High quality output at minimal expense. Use it, share with it and enjoy the accolades.
