Tested on the windows 10 side of my laptop with the command:
"C:\Users\Steve\Desktop\ffmpeg-20160105-git-68eb208-win64-static\bin>ffmpeg
-i C:\Users\Steve\Desktop\Jan22016-150PM-b6cs7K.mov -vf fps=fps=30
-c:a copy -vcodec libx264 -crf 20 -preset slow asdf.mp4"

and it spits out a fixed frame rate 30fps video and looks purdy. VLC
plays it no problems. This will preserve the audio feed exactly, and
only re-encodes the video using x264 at a pretty decent quality. Final
size is 9 MB.
