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, please take a look:

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
  • Dude: 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. – ldiastx Feb 22 '16 at 15:48
  • Just try running Dude's command inside Terminal! It should loop thru all the MKV files in the current folder/directory, converting them to MP4. It preserves the names of the files, just changing the extension. – jimtut Feb 22 '16 at 17:31

    PERFECT! Thanks so much. Works like a charm. – ldiastx Feb 23 '16 at 13:23
  • Curious what "${f%mkv}mp4" is? Learn more about "String Operations": tldp.org/LDP/abs/html/refcards.html#AEN22828 – beausmith Aug 7 '16 at 19:41
