Well, after finding out that Miro does not really handle WMV files on Windows, I had to look for another option for video compression on that platform. Fortunately, one of my co-workers suggested Quick Media Converter HD. QMC is a Windows only freeware program that converts to a number of formats, including H.264 MP4 for iPhone. I tried converting the sample HD video (which is in WMV format) that ships with Windows 7 and it reduced the video from 25MB to 4MB using the MP4, 640 X 380 preset. The performance in terms of the time it took to do the conversion was pretty good, even though this was a short clip. The interface for QMC is not the prettiest, but I think it’s a good tool to have if you work with videos and need to support teachers using Windows.
