Our Video Module currently supports MP4 videos only. If you have videos in other formats, it's possible to convert them into MP4s. An added benefit of conversion is that you can often convert to a web friendly format. There are a zillion options for converting videos - Google can tell you all about them - but we've list just a couple of options below. We know these options work but we do not endorse these products or guarantee that they will work for you.
