What all Windows editing application Read mores have in common is that they love .WMV files. If we can change .MP4 files (and even files from other camcorders) into .WMV files, simply and cheaply, and preserve the fidelity, we’re in the sweet spot of easy editing. There is a free program available for all Windows users that does this. It’s called “Any Video Converter.” I have already written a couple of articles about this program, but I now propose it as a general solution – the Rosetta Stone for Windows Movie Maker of all flavors, on all platforms.
