Batch convert a folder of .mkv files to .m4v files using ffmpeg in MAC OS X
17,472
for f in *.mkv;do ffmpeg -i "$f" -c:v copy -c:a aac -b:a 256k "${f%mkv}mp4";done
Or if you don't need to re-encode:
for f in *.mkv;do ffmpeg -i "$f" -c copy "${f%mkv}mp4";done
If you want to put the new files in a separate directory:
mkdir output
for f in *.mkv;do ffmpeg -i "$f" -c:v copy -c:a aac -b:a 256k "output/${f%mkv}mp4";done

Is there a way to batch covert a folder of .mkv files to .m4v files using ffmpeg in Mac?
I setup a service that will do individual files, but I really would like to batch them.
The 'Run Shell Script' that I'm using is:
for f in "$@" do /Users/username/Movies/ffmpeg -i "$f" -c:v copy -c:a copy "${f%.*}.m4v" done
Here is a screen shot of what I have that works for individual files:

ldiastx over 8 yearsDude: I am struggling with this a bit. The name of my files are this format.... tvshow s01e01 - name of tvshow.mkv my script still will do individual files within the folder. I just right click the file and look under services and then select the name of my service that i created. If I try right clicking on my folder name. I get an error.
