NAME

divxenc - the interactive shell script ripper

SYNOPSIS

divxenc
[-1p|-2p|-3p|-fq|-b|-e|-r|-sc|-scan|-iso|-spr|-bpp|-bpb|-v|-help] [-p
<preset>]

DESCRIPTION

divxenc 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 MPEG-4 SP/ASP video format. For more information and a FAQ, visit http://divxenc.sourceforge.net

REQUIREMENTS

- MEnocder >= 1.0rc2 (SVN highly recommended)
- lsdvd
- LAME (for MP3 audio encoding)
- FAAC (for AAC audio encoding)
- dvdxchap from ogmtools (for DVD chapters export)
- neroAacEnc (for AAC/AAC+ audio encoding)
- aacplusenc (for AAC+ audio encoding)
- oggenc (for Vorbis audio encoding)
- flac (for FLAC audio encoding)
- mkvmerge from mkvtoolnix (for AVI -> MKV container conversion)
- MP4Box from gpac (for AVI -> MP4 container conversion)
- ogmmerge from ogmtools (for AVI -> OGM container conversion)

PARAMETERS

-1p Encode in 1-pass mode

-2p Encode in 2-pass mode

-3p Encode in 3-pass mode

-fq Encode the DVD or video file in fixed-quant mode (constant qual: ity)
<passmode> -p <preset>: Use a predefined DivX quality preset, where <passmode> is the desired encoding mode (-1p or -2p or -fq) and <preset> is the desired quality preset to use (see below).
You can choose from 9 different presets:

nq ---> Normal Quality (NQ) preset hq ---> High Quality (HQ) preset vhq --> Very High Quality (VHQ) preset (recommended)
ehq --> Extreme High Quality (EHQ) preset (recommended)
uhq --> Ultra High Quality (UHQ) preset (recommended)
ihq --> Insane High Quality (IHQ) preset hwp --> Stand-alone HW compatible (HWP) preset ps3 --> Sony PS3 compatible (PS3) preset ipod -> Apple iPod preset

Example of presets usage: divxenc -2p -p vhq

The above example will encode the DVD or
input video file in 2-pass mode using the
Very High Quality (VHQ) preset
-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
down.
-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 '/home/username/.divxenc'
-r Reset configuration file. As of version 1.1.7,: divxenc 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 divxenc 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
/home/username/.divxenc/config
-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/video file 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 only for DVD scans
-iso Create an ISO image out of the DVD content and: store it to disk.
-spr Calculate the Storage and Pixel Aspect Ratios: (SAR/PAR) for various resolutions.
-bpp This is a informative option which lets you calcu: late 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.
-help Display built-in help of the divxenc script and: exit
-v Display version of the divxenc script and exit
