VeryPDF PowerPoint to Video Converter is an application that helps you convert your PowerPoint presentations to the following video format files: AVI, MPEG, MP4, MOV, FLV, ASF, SWF.
In terms of appearance, the program comes with a beautiful and modern interface. The conversion itself consists in recording the on-screen animation.
In other words, whatever motion appears on your screen, it will occur in the video presentation too. For instance, if you move the mouse, the cursor motion on the desktop will be part of the clip. Since the conversion is actually a faithful recording of what is happening on the screen, the converting time is equal to the duration of the PowerPoint presentation. When starting the conversion, a new window will appear. From this point, you can't work simultaneously with other apps, because this program uses almost all your computer resources. Even interrupting the running process is a hard thing to do.
One option that I liked is the ability to resize the video appearance on the screen, ranging from 100x100 to 1680x1050. The program doesn't boast with other special features. However, it has more drawbacks than advantages. It has neither a preview section, nor the ability to add sound to the video file.
To make things short, VeryPDF PowerPoint to Video Converter is a tool that turns your PPT, PPS or PPTX format files into ordinary clips, which can be uploaded to whatever website you want. But the absence of adjusting settings and the negative effect on my PC activity (in the sense that it is very much slowed down) are what stop me from using it.
