Shift times of multiple .srt files at once with the same time length given

[rby03]

I have a folder of .srt files that are not synced correctly with the RAWs of a TV series, as those RAWs don't include the opening. If it was a single file what I'd do would be using the Aegisub's Times Shift option to to increase/decrease the subtitle's starting and ending position with a given length (in this case I need to "delay" every subtitle by 2 minutes and 56 seconds). However I need to do this for 49 files but I don't know a way to bulk edit all the files.

Open subtitle edit/tools/batch convert/offset time codes then drag the folder into batch convert.

Thanks a lot!

i do this with python script and subtitleedit...
This edits and remerges english srt subs for all mkv files in a folder.


import os
import subprocess, shlex
import re

#LOCATION OF APPS/binaries
subtitleedit = "C:\Program Files\Subtitle Edit\SubtitleEdit.exe"
directory= "C:/Program Files/MKVToolNix/mkvmerge.exe"

#get directory, files
cwd = os.getcwd()
files = os.listdir()

for file in files:
print(f"converting {file}")
if "E01" in file or "E02" in file or "E03" in file: #I had situation where some episodes needed different offsets, and i had manually specified it, this isnt really critical.
os.system(f'"{subtitleedit}" /convert {cwd}/{file} srt /offset:-00:00:10:00') #-00:00:10:00 here sets the subtitles 10 seconds earlier.
else:
os.system(f'"{subtitleedit}" /convert {cwd}/{file} srt /offset:-00:00:10:00')
print("conversion complete\n")

#remerge fsubs into file
files = os.listdir()
