Pro Tip: Batch-remove the audio from a set of video files

I recently wanted to remove the audio from a bunch of B-Roll I was giving to someone else, because lets face it, I’m always talking about something ultra-nerdy in the background.

In my case they were the MOV files straight out of the camera, and I wanted them put into a directory called `no-audio`. On linux or mac, you can do this:

for i in *.MOV; do ffmpeg -i "$i" -vcodec copy -an "no-audio/${i%.*}.MOV"; done

We make use of the ability to write small shell scripts on one line, as well as bash Parameter Expansion to allow us to form the new name out of the old name.
