According to the Help section on the web site, it can convert just about any video file. In addition the software can also convert YouTube videos into iPod/iPad video formats, HTML5 and other stuff.
From what I can tell reading the log history it should be able to handle:
- Converting video audio to MP3
- OGG (don't know if that is OGG Video or Audio)
- H.264 using Xvid
Windows .wmv I'm not sure about and there are other bugaboo formats. You could always ask the company if the support a certain video format. Just another option for your video tool kit.
