       h264enc  is  an  advanced  and  powerful  interactive menu-driven shell
       script which uses  the  encoding  utility  MEncoder  from  the  MPlayer
       project.  The  script  can  be  used to encode DVDs, (S)VCDs or regular
       video files to the high-quality H.264 video format (also known  as  AVC
       (Advanced  Video  Coding) or MPEG-4 Part 10). At the moment, the script
       supports virtually all options of the libx264 library and a variety  of
       audio  codecs, including support for up to three DVD audio tracks muxed
       into the MKV/MP4/OGM/TS containers.  h264enc is targeted  primarily  at
       power  users  or users who understand the process of video encoding and
       want to tweak their settings in order  to  achieve  the  best  possible
       quality/file  size  of  their encodes.  For more information and a FAQ,

       h264enc uses a configuration file stored in the user's  home  directory
       inside  a  hidden directory named as .h264enc where the user can enable
       or disable many of the supported audio/video  filters  and  containers.
       This  can  reduce the time it takes to pass through the script when the
       user disables filters  and/or  containers  he  never  intends  to  use.
       Further,  the  configuration  file  stores  the  paths  to the required
       programs and a few other things like some script options, MPlayer flags
       and email support.

       <passmode> -p <preset> [-t <tune>] [-pf <profile>]
              Use a predefined H.264 quality preset, where <passmode>  is  the
              desired  encoding  mode  (-1p  or -2p or -3p or -qp or -crf) and
              <preset> is the desired quality preset to use (see below).  Note
              that  the  -t  and  -pf  options only work with the x264 presets
              below! See examples at the end of this option.

                     Example of presets usage: h264enc -2p -p hq

                     The above example will encode  the  DVD  or
                     input  video  file in 2-pass mode using the
                     High Quality (HQ) preset

                     Load a custom preset from a file:
                     h264enc -2p -p cp /path/to/file/preset.cfg

                     Please have a look at the  preset.cfg  file
                     inside  the  h264enc package to give you an
                     example on how to write  a  custom  preset.
                     The  preset.cfg  file  is  usually  located
                     inside the doc  directory  of  the  h264enc

                     Examples   of   x264  presets/tune/profiles
                     h264enc -2p -p slow
                     h264enc -2p -p slow -t film
                     h264enc -2p -p slow -pf main
                     h264enc -2p -p slow -t film -pf high

                     The first example encodes  the  input  with
                     x264's  slow  preset.   The second one does
                     the same but tunes the encode settings  for
                     film  footage.  The third example is as the
                     first  one  but  selects  the  main   H.264
                     profile  and  the  last example uses both a
                     tuning for film and selects the high  H.264
                     profile. You can also switch the -t and -pf
                     options, eg: h264enc -2p -p slow  -pf  main
                     -t film

       -b /path/to/file/batchfile
              Load  a batch file generated by this script.  This
              option can be useful for testing or debugging  the
              MEncoder parameters and for batch encoding.

       -e     Edit  the  config  file  from within the terminal.
              This option defaults  to  using  the  'nano'  text
              editor  but  one  can  manually  set his preferred
              editor in the EDITOR variable of the config  file.
              The      config     file     is     located     in

       -r     Reset configuration file.  As  of  version  8.5.7,
              h264enc  uses  a configuration file which contains
              the paths to the programs needed for  its  correct
              operation.  This option tells the script to remove
              and recreate the config  file  using  the  default
              values.  It  can  be  used to restore the original
              values of the config file in  case  the  user  has
              modified   it  and  wants  to  get  rid  of  those
              modifications.  It is also used for resetting  the
              config  file  in  case  the  user  has installed a
              required program after h264enc has  generated  its
              config  file. If this is the case, the config file
              will not contain the path to the  newly  installed
              program  so  one has to reset the file in order to
              find it.  This  is  because  the  config  file  is
              generated/updated only once: if it's not available
              on the user's system  and  during  config  version
              updates.   The  configuration  file  is located in

       -sc    Perform a sanity check. This will  check  for  the
              programs   which  are  required  for  the  correct
              operation of this script and  it  will  print  the
              status in a list. It will also display which audio
              codecs are supported by MEncoder.

       -scan  Scan  the   DVD   disc   and   display   extensive
              information  about  it.  With this option, one can
              display or export the information  to  a  file  on
              disk in text, perl, python, ruby or xml format.

       -iso   Create  an  ISO  image  of the DVD disc. Note that
              this option does no do any stripping  of  specific
              titles, audio languages and/or subtitles. It dumps
              the DVD content 1:1 to an ISO image.

       -spr   Calculate the  Storage  and  Pixel  Aspect  Ratios
              (SAR/PAR) for various resolutions.

       -mfr   Calculate  the  maximum  allowed  frame references
              within DPB (Decoded  Picture  Buffer)  limits  for
              different H.264 levels and resolutions.

       -bpp   This  is  an  informative  option  which  lets you
              calculate the Bits  Per  Pixel  (bpp)  values  for
              various resolutions.  The bpp value represents how
              much bits each pixel  gets.  The  higher  the  bpp
              value is, the more distinct colors the pixels will
              have which  leads  to  a  higher  overall  picture
              quality.  Note that these values are not absolute!
              For video content with a lot of black in it, a bpp
              value  of  0.14  may look very good. Video content
              with a lot of high motion scenes  may  still  look
              bad  with  a  bpp  value  of  0.20, so this really
              depends on the content you are willing  to  encode
              and the resolution you choose when scaling down.

       -bpb   This  option is similar to the -bpp one, except it
              calculates the Bits Per  Block  (bpb)  values  for
              various  resolutions.  The bpb value expresses how
              many bits each 16x16  macroblock  gets.  Good  bpb
              values are between 37-52. As is the case with Bits
              Per Pixel, the bpb values  are  not  absolute  and
              depend  on  the  video  content you are willing to
              encode and the resolution you choose when  scaling
