How to split dual language subtitle?

[vgallotti]

Hi everybody

I have been reading and learning a lot on this forum, but this time I need help!

After ripping a dvd I noticed it has a dual language sub/idx which I converted to srt.
Now I want to split this file so I have one subtitle file for both languages.

Found this post with similar problem

https://forum.videohelp.com/threads/388522-Separate-dual-language-subtitle-ass

I tried the offered solution

The Japanese seems to be limited to lines using the "PP-OP1-RO" or "PP-ED1-RO" styles. Just delete those. E.g. in Aegisub

But this didn't work for me. Probably because the subtitles have a different style...

If someone knows how I can solve this I would very much appreciate it!
Subtitle file is attached.

Kind regards

FR.srt
EN.srt

There must be a smarter way than this but I don't know it.

import re


def parse_srt_file(file_path):
    with open(file_path, 'r', encoding='utf-8-sig') as file:
        srt_content = file.read()

    subtitle_blocks = re.split(r'\n\n', srt_content)
    subtitles = []

    for block in subtitle_blocks:
        lines = block.strip().split('\n')
        index = int(lines[0])
        time_interval = lines[1]

        dialogue_content = tuple(lines[2:])
        subtitles.append((index, time_interval, dialogue_content))
    return subtitles


def process_and_write_subtitles(subtitles_list):
    with open('FR.srt', 'w', encoding='utf-8') as fr_file, open('EN.srt', 'w', encoding='utf-8') as en_file:
        for index, time_interval, dialogue_content in subtitles_list:
            fr_file.write(f"{index}\n{time_interval}\n{dialogue_content[0]}\n\n")
            en_file.write(f"{index}\n{time_interval}\n{dialogue_content[len(dialogue_content) // 2]}\n\n")


process_and_write_subtitles(parse_srt_file('FR-ENG.srt'))

Damn this is amazing! Thank you very much, what program did you use to execute this command?

That's a Python script. You execute it using Python. You shouldn't bother with it though. I just added it to prove that it can be done. The script may fail for other cases since I've written it only using your fr-eng srt as a reference. I added the split subtitles as attachments.
