You can create videos from PowerPoint presentations in the following three formats:

2. Internet & DVD - For uploading to the Web and burning to standard DVD (640 x480)

3. Portable Devices - For devices like iPod or Zune (like a video podcast); Small text may be difficult to read (320 x240)

PowerPoint will create videos in the Windows Media (wmv) format only.
