20230812Use python3 to convert SRT format subtitles to SSA format under WIN102023
/8/12 20:58
The SSA format of this article is based on the format of [Batch Subtitles Converter v1.23]!
1.
Origin: None of the various subtitle conversion software/gadgets found on the Internet fully satisfy me!
[There are all kinds of small flaws]
So I decided to write a practice by myself using python3!
The python script in this article only handles UTF8-encoded SRT format subtitles. For ANSI-encoded SRT format, please refer to this article for modification!
! ! ! ! Batch Subtitles Converter (batch subtitle conversion) v1.23 Green English version: The position and color/font/font size of the required SSA subtitles cannot be modified/customized.
subresync.exe: UTF8 encoded subtitles are not supported! And the position and color/font/font size of the required SSA subtitles cannot be modified/customized.
vobsub.dll
Technical points:
Red.Eye.2005.2160p.BluRay.REMUX.HEVC.DTS-HD.MA.5.1-FGT.cn9.srt
converts the English letters of "Imminent" into Chinese SRT format subtitles after google translation into SSA format !

Important: To modify the timeline in SRT format to SSA format, you need to use the string processing/splitting function of python3!

This article will discuss how to split strings using delimiters in Python.
1. Use the re.split() function
A simple solution to split a string by the occurrence of a pattern is to use the built-in function re.split(). A pattern can consist of one or more delimiters:
Split on a single delimiter
To split a string using a single delimiter, you simply pass that delimiter to the re.split() function.
import re
if __name__ == '__main__':
s = 'Hello,World'
res = re.split(',', s) # split with comma
print(res) # ['Hello', 'World']
