If no input file is given, audio/video grabbing is done.
As a general rule, options are applied to the next specified
-file. For example, if you give the @option{-b 64} option, it sets the video
+file. For example, if you give the @option{-b 64k} option, it sets the video
bitrate of the next file. The format option may be needed for raw input
files.
@item -comment string

initial complexity for single pass encoding
@item -deinterlace
Deinterlace pictures.
-@item -interlace
+@item -ilme
Force interlacing support in encoder (MPEG-2 and MPEG-4 only).
Use this option if your input file is interlaced and you want
to keep the interlaced format for minimum losses.
@item -acodec codec
Force audio codec to @var{codec}. Use the @code{copy} special value to
specify that the raw codec data must be copied as is.
+@item -newaudio
+Add a new audio track to the output file. If you want to specify parameters,
+do so before @code{-newaudio} (@code{-acodec}, @code{-ab}, etc..).
+
+Mapping will be done automatically, if the number of output streams is equal to
+the number of input streams, else it will pick the first one that matches. You
+can override the mapping using @code{-map} as usual.
+
+Example:
+@example
+ffmpeg -i file.mpg -vcodec copy -acodec ac3 -ab 384 test.mpg -acodec mp2 -ab 192 -newaudio
