When I use 'add file to library', nothing seems to happen. I don't get this..

For starters you should have -i a lot earlier on the line. There are some other errors as well, here is what I got so far: INFILE="$1" OUTFILE="$1.mp4" ffmpeg -i "$INFILE" -f mp4 -vcodec mpeg4 -maxrate 1000k -b 700k -qmin 3 -qmax 5 -bufsize 4096k -g 300 -acodec libfaac -ab 192k -s 480x320 -aspect 4:3 "$OUTFILE" Sadly it still doesn't produce any results to be proud of, the video encodes into a half-speed, double-length monster. Audio plays back fine. Whups I spoke too soon, this doesn’t work at all. For starters you should have -i a lot earlier on the line. There are some other errors as well, here is what I got so far:

INFILE=”$1″

ffmpeg -i “$INFILE” -f mp4 -vcodec mpeg4 -maxrate 1000k -b 700k -qmin 3 -qmax 5 -bufsize 4096k -g 300 -acodec libfaac -ab 192k -s 480×320 -aspect 4:3 “$OUTFILE”
