Need quick way to remove audio from mp4 file

I have about 30-40 hours worth of .mp4 video files and I need to remove the audio from each of the files (there are about 30 files or so).  Is there a quick and efficient way to do this without having to encode all of the files?

Nope!!
 there is no easy way or simple way.
So you have a problem.
The first this is a quicktime format not common so it's probably managed by Quicktime too.
MP4

These are the most popular
