This notebook will convert your japanese VobSub subtitles (.idx + .sub) to conventional text subtitles (SubStation Alpha). You might need text subtitles
to adjust subtitle style to your preferences or for automatic dictionary lookup and flashcard creation.
This will also work with subtitles in .sup format. You can convert them to a .idx + .sub combo with bdsup2subpp.
This notebook uses manga-ocr for character recognition, vobsub2png
to parse the VobSub Subtitle format, and pysubs2 to create text subtitles.
This notebook is not perfect; it has problems with mixed vertical and horizontal text, italics, and sometimes it ignores opening parentheses but it's still a lot better than existing software.
