And it has a multi-lingual user interface. You can choose one that you are accustomed to use from the provided six languages, that is, English, French, German, Italian, Japanese, Simplified and Traditional Chinese.
However, I have to tell you that this free powerpoint to video converter is not perfect. In the first place, the video format it can convert to is very limited. It can only convert PowerPoint to WMV, ASF. And it does not support batch conversion, so you cannot convert many PowerPoint files to many video formats at a time. And if your PowerPoint has video clips in it, it may not be kept to the output video.
If you want to solve the above problems, you can consider using Leawo PowerPoint to Video Pro. It can convert PowerPoint to video of 23 formats, so that after conversion, you can have much more choices. For example, if you convert PowerPoint to flash video, you can upload it to various video sharing websites such as YouTube, Google video, Dailymotion, MetaCafe, etc. And if you convert PowerPoint to MP4 video, you can sync it to iPod, iPhone, iPad through iTunes or transfer it to other portable devices that support MP4 video like PSP, mobile phone, etc. and enjoy it anywhere and anytime you want.
And it can batch process as many as 12 PowerPoint files per conversion, which can save you some time. Moreover, it can retain everything for you from the original PowerPoint file to the output video, even music, movie clips and flashes and so on. Of course, it has all the functions that the free PowerPoint to Video Converter has.
