DVD Subtitle Tools

IfoEdit is an amazing tool allowing to modify and manipulate ifo-files in very comfortable way. Since version 0.94 it contains also simple but effective DVD authoring function that multiplex m2v video files together with mp2/ac3/dts sound files and sup subtitle files without necessity of using expensive official DVD authoring software.
Following tools extend this functionality and give you a possibility to create your own multilanguage subtitles to your movies. DVD subtitle encoder converts source text file into DVD subtitle binary files acceptable for IfoEdit.

DVD Subtitle Encoder

DVD subtitle encoder creates sup-files suitable for IfoEdit authoring.

Source text file contains subtitles in format
{frame_from}{frame_to}line
{frame_from}{frame_to}line_1|line_2

or comments in format
;this is comment line, will be ignored

External bitmaps can be also loaded from given location
{frame_from}{frame_to}{d:\my_pictures\file_name_1.bmp}

Source text file can also contain processing commands:

FrameW=n	frame width (720, 704)
FrameH=n	frame height (576, 480)
FrameRate=n	frame rate (25, 29.97)
Delay=n	subtitle delay (in frames)
(previous commands can be specified only at the beginning of source text)
FontName=name	subtitle font name
FontCharSet=n	subtitle character set (for more detail information see Font Setting)
FontSize=n	subtitle font size
FontStyle=n	subtitle font style (REGULAR, BOLD, ITALIC, UNDERLINE)
Contour=n	creates black contour around subtitle characters (n pixels wide)
Palette=n	color palette used
Alpha=n	alpha channel setting
OnTop=0|1	subtitles are created on the top of the screen
Justify=C|L n|R n	subtitles are justified to the center/left/right (n pixels from the frame border)
Indent=n	subtitles are indented n lines from the bottom/top of the frame (should be even number)
DynamicSize=0|1	subtitle frames have dynamic bitmap size
RightToLeft=0|1	text is read right to left (Hebrew, Arabic)
ShowBitmap=0|1	creates bitmap files during processing

Every command is valid until it is set to new value. Default values are taken from C:\Documents and Settings\<user>\DVDSupEncode.ini,
section [Default], and are predefined as follows:

FrameW=720

FrameH=576

FrameRate=25

Delay=0

FontName=Arial

FontCharSet=238

FontSize=23

FontStyle=REGULAR

Contour=1

Palette=3210

Alpha=FFF0

OnTop=0

Justify=C

Indent=40

DynamicSize=0

RightToLeft=0

ShowBitmap=0

Additional sections [profile] can be specified in DVDSupEncode.ini. These profiles allow you to switch quickly your favorite predefined settings. Profiles can be activated by command line parameter -p:profile. Structure of these profiles (i.e. entries) is the same as for [Default].

The priority of activation of settings is as follows:

1. setting in source-text

2. setting in selected profile

3. setting in Default profile

4. program internal setting

During process of creation of subtitle sup-file is generated log-file. Into log-file are reported warnings and errors in case that created subtitle doesn't fit into the screen.

Loading external bitmaps is also supported. Size of these bitmaps should be the same as size of the frame, color-depth will be reduced to 4 according to luminance, i.e. interval <0,255> is uniformly divided into 4 ranges and every range is associated with one entry in subtitle palette.

IMPORTANT: After authoring in IfoEdit don't forget to set up Subtitle Color properly!

For PALETTE=3210 can be used following colors:
VTS_01_0.IFO
     VTS_PGCITI
         VTS_PGC_1

	[000000a5]	Color 0 Y Cr CB	16 128 128	[10 80 80 ]
	[000000a9]	Color 1 Y Cr CB	32 128 128	[20 80 80 ]
	[000000ad]	Color 2 Y Cr CB	128 128 128	[80 80 80 ]
	[000000b1]	Color 3 Y Cr CB	235 128 128	[eb 80 80 ]

It is recommended firstly to check subtitles on DVD rewritable disk (and thus prevent from damaging of recordable media).

DVD Subtitle Decoder

DVD subtitle decoder creates text files from subtitle sup-file (result of VobEdit demultiplexor).

Result is text file in format
{frame_from}{frame_to}{VTS_01_0.20_000001.bmp}

With option -bitmap are also created related bmp-files.

DVD Subtitle HTML Viewer

DVD subtitle HTML viewer creates html-files from subtitle sup-file (result of VobEdit demultiplexor). This html-file contains useful information about every subtitle block such as address, size, timing, subtitle position on the screen, palette, alpha-channel setting etc..

With option -bitmap are also created bitmaps for every subtitle screen.
