PowerPoint presentations are a very useful medium to convey your message but the lack of portability and the hassle of having MS Office installed on the receiving computer has decreased its popularity. People are ditching powerpoint for cloud applications like Google Docs.
However, there is something you can do to smooth this out and make your PowerPoint presentation more portable and efficient. The solution is to convert the presentations into videos.
One of the best tools to do that is PowerPointVideoConverter. This free utility allows you to convert your presentations into popular video formats such as AVI, WMV and MPG. You can even convert it to an MP3 Audio file. During the conversion process, you can actually specify the transition time you want between each slide and even choose the desired quality of the video. Do remember though, that a higher quality video will lead to a large file.
