AVS to BluRay SUP/PGS and BDN XML

This program can be used to transform AviSynth scripts, which produce RGBA output, to BDN XML+PNG format. This in turn can be transformed into a SUP file, which can be used to master a BluRay disc with subtitles.

Usage instructions

0. If you want to build it: On Ubuntu:

sudo apt-get install mingw32 mingw32-binutils
make

1. Prepare subtitles. You can either produce subtitles in a normal format like SRT or ASS/SSA, or produce an RGBA video beforehand.

2. Create an AviSynth script. If you made a regular subtitle file, you can use something like this:

video=AviSource("video.avi")
# This requires at least VSFilter 2.39
MaskSub("subtitles.ext",video.width,video.height, video.framerate,video.framecount)

If you created an RGBA video, do something like this instead:

AviSource("subtitles_RGBA.avi")
FlipVertical()

3. Run the program:

avs2bdnxml -t Undefined -l und -v 1080p -f 23.976 -a1 -p1 -b0 -m3 -u0 -e0 -n0 -z0 -o output.xml input.avs

4. You get a BDN XML file in the following format:

    <?xml version="1.0" encoding="UTF-8"?>
    <BDN Version="0.93" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="BD-03-006-0093b BDN File Format.xsd">
    <Description>
    <Name Title="Undefined" Content=""/>
    <Language Code="und"/>
    <Format VideoFormat="[ 480i / 480p / 576i / 720p / 1080i /1080p ]" FrameRate="[ 23.976 / 24 / 25 / 29.97 / 50 / 59.94 ]" DropFrame="false"/>
    <Events LastEventOutTC="00:00:00:00" FirstEventInTC="00:00:00:00" ContentInTC="00:00:00:00"
    ContentOutTC="00:00:00:00" NumberofEvents="[ number of encoded frames ]" Type="Graphic"/>
    </Description>
    <Events>
    <Event Forced="[ False / True ]" InTC="00:00:00:00" OutTC="00:00:00:00">
    <Graphic Width="0" Height="0" X="0" Y="0">000000.png</Graphic>
    </Event>
    </Events>
    </BDN>

5. To convert output directly to BD .sup format, simply change extension for output file in programm call to .sup.

Don't use BDSupEdit or BDSup2Sub if you enabled -b for splitting images in multiple parts!

Commandline Parameters

Usage: avs2bdnxml [options] -o output input

Input has to be an AviSynth script with RGBA as output colorspace

  -o, --output <string>        Output file in BDN XML format
                               For SUP/PGS output, use a .sup extension
  -j, --seek <integer>         Start processing at this frame, first is 0
  -c, --count <integer>        Number of input frames to process
  -t, --trackname <string>     Name of track, like: Undefined
  -l, --language <string>      Language code, like: und
  -v, --video-format <string>  Either of: 480i, 480p,  576i,
                                          720p, 1080i, 1080p
  -f, --fps <float>            Either of: 23.976, 24, 25, 29.97, 50, 59.94
  -x, --x-offset <integer>     X offset, for use with partial frames.
  -y, --y-offset <integer>     Y offset, for use with partial frames.
  -d, --t-offset <string>      Offset timecodes by this many frames or
                               given non-drop timecode (HH:MM:SS:FF).
  -s, --split-at <integer>     Split events longer than this, in frames.
                               Disabled when 0, which is the default.
  -m, --min-split <integer>    Minimum length of line segment after split.
  -e, --even-y <integer>       Enforce even Y coordinates. [on=1, off=0]
  -a, --autocrop <integer>     Automatically crop output. [on=1, off=0]
  -p, --palette <integer>      Output 8bit palette PNG. [on=1, off=0]
  -n, --null-xml <integer>     Allow output of empty XML files. [on=1, off=0]
  -z, --stricter <integer>     Stricter checks in the SUP writer. May lead to
                               less optimized buffer use, but might raise
                               compatibility. [on=1, off=0]
  -u, --ugly <integer>         Allow splitting images in ugly ways.
                               Might improve buffer problems, but is ugly.
                               [on=1, off=0]
  -b, --buffer-opt <integer>   Optimize PG buffer size by image
                               splitting. [on=1, off=0]
  -F, --forced <integer>       mark all subtitles as forced [on=1, off=0]
