Is there a way to get the sound from an MP4 file to work in Windows Movie Maker? I tried doing some research and found that some people suggested just converting to a WMV file format, but both the converters I downloaded degraded the quality of the video. So 1. Is there a way to use MP4 in Movie Maker and keep both sound and video quality? or 2. Is there a good converter I can use that won't degrade the quality of my video when converting to WMV? I have a Windows 8.1 machine.
