split one subtitles file (.srt) in two (useful if your movie is contained in two files)
This is a very ad-hoc python code. It basically creates a second subtitles file starting from your imput mark (your splitting time point). It is a common issue to have two video files and only one entire_movie subtitles file. This program only adjusts the subtitles by substracting the duration of the first part of the video (so subtitles of second part start at 0 time). If you want to make it adaptable to more situations (ie. video splitted in N files) feel free to fork the project or ask me to do it.
Place your original subtitles file (.srt) in the source code folder (I know, just got lazy to check for paths! :-P )
Edit the config.cfg file with your own parameters
1.1) file_name = <your_file_name_placed_in_your_code_folder> (example: file_name = No Maps For These Territories.srt) <-- no quotes used
1.2) set your partition mark, search for the time mark that comes after the first video part (example: partition_mark = 00:44:23,280)
1.3) the offset to substract is the duration of the first part of the video in seconds (offset_to_substract_in_seconds = 2660, first part ends at 44:20, 44 minutes 20 seconds = 44*60 + 20 = 2660 seconds)
run the subtitles_offset: python subtitles_offset.py
that's it, you'll see your brand new second_part.srt subtitles file!
