Media encoder (ffmpeg wrapper)

  It helps to convert media files into different
  formats in a simpler way with friendly UI showing
  progress, eta, and compression rate.


Arguments:
  files                        one or more files to encode

Options:
  -v, --version                print version
  -i, --info                   print media information
  -d, --dir <name>             output directory
  -s, --start-time <hh:mm:ss>  trim start time
  -e, --end-time <hh:mm:ss>    trim end time
  --copy                       copy the input stream (the output will not to be re-encoded)
  -c, --custom <value>         use custom ffmpeg options
  -f, --format <format>        output format (choices: "mp3", "ogg", "mp4", "sd:480p", "hd:720p", "fhd:1080p", "qhd:1440p", "2k:1080p",
                               default: "mp4")
  -h, --help                   display help for command

Hint:
  You can also use short names for the "--format" argument.
  For example, instead of "--format sd:480p", you can type
  "--format sd" or "--format 480p".

Formats:
  mp3 (mpeg-1 Audio Layer 3) is a music format that can compress files by up to 95%.
  ogg is a multimedia container format commonly used for audio and video files.
  mp4 is a widely used multimedia file storage format for storing video.
  sd or 480p is a video format with 4:3 ratio and 640x480 size.
  hd or 720p is a video format with 16:9 ratio and 1280x720 size.
  fhd or 1080p is a video format with 16:9 ratio and 1920x1080 size.
  qhd or 1440p is a video format with 16:9 ratio and 2560x1440 size.
  2k video or 1080p is a video format with 1:1.77 ratio and 2048x1080 size.

Examples:
  $ npx menc <filename>

  Since "--format" argument is default to "mp4", this command
  will compress your input file and create a new <filename>.mp4
  file inside the current directory.

  $ npx menc -d 123 *.mov

  It will compress all MOV files from the current directory and
  put them inside the "123" sub-directory.

  $ npx menc -f hd <filename>

  It will convert the <filename> video to HD:720p format and
  create a new <filename_hd>.mp4 file inside the current
  directory.

  $ npx menc -s 10 -e 1:09:04 <filename>

  Compress the input file into a new <filename>.mp4 from
  the 10th second until 1:09:04.

  $ npx menc -e 1:05 --copy <filename>

  Trim the input file (no re-encoding) into a new file from
  the beginning until 1:05.

  $ npx menc --custom '-vf scale=320:-2' <filename>

  Scale the output video, making the width equal to 320, keeping
  the aspect ratio ("-2" ensures that the aspect ratio always
  conforms to the codec requirements).

  $ npx menc -c '-qscale:a 6' -f mp3 <filename>

  Set audio quality (variable bitrate) for the output MP3 file
  to 6 (smaller size).
