There are many many (hundreds?) of options that you can add to ffmpeg

Here is a recent commandline:

ffmpeg -i maskred.mp3 -ss 42 -metadata author="Edgar Allan Poe" -metadata album="The Masque of the Red Death" -metadata comment="The story follows Prince Prospero's attempts to avoid a dangerous plague, known as the Red Death, by hiding in his abbey. He, along with many other wealthy nobles, hosts a masquerade ball in seven rooms of the abbey, each decorated with a different color. In the midst of their revelry, a mysterious figure disguised as a Red Death victim enters and makes his way through each of the rooms." -b:a 128K -c:a aac  "The Masque of the Red Death.m4b"

or this

for i in *; do ffmpeg -n -f concat -safe 0 -i <(for f in $i/*.mp3; do echo "file '$PWD/$f'"; done) -metadata title="$i" -vn -c:a aac -b:a 64K  $i.m4a ; done

or

ffmpeg -i rolf.mp4 -ss 8:37 -to 8:41 rolf2.mp4

or

ffmpeg -i Witches\ 01.mp3 -i Witches\ 02.mp3 -i Witches\ 03.mp3 -i Witches\ 04.mp3 -i Witches\ 05.mp3 -i Witches\ 06.mp3 -i Witches\ 07.mp3 -metadata title="Witches" -metadata comment-"Recorded 16 Jul 1999" Witches.mp3

(just pulled from my `history`)

When this kiss is over it will start again But not be any different
