<p>What portion of a video file is audio information? I have a large number of m2t video files where the audio is worthless to me. I'm curious if removing the audio portion from these files will notably decrease the file size. Could someone give me a ballpark estimate of how much this will decrease file size? For example, how much will a 5 GB m2t video file be reduced?</p>

Not enough to bother re-encoding it - typically single figure %
