Script that shifts (delay/advance) subtitle time in a file or across an entire folder. Supported files are .srt, .vtt, .sub, .sbv, .lrc, .ass and .ssa.
python SubShift.py <file_or_folder_path> <time_to_shift>
-
file_or_folder_pathpath to a file or a folder. -
time_to_shifttime to advance the subtitle or delay it. time can be 0.0 ,00:00:00.00 or 00:00:00,000(milliseconds)
in this example, subtitle will be delayed across all sub files in 'Salam' folder by 2 seconds.
python SubShift.py "C:\subs\Salam" -0.2
in this example, subtitle will be advanced in 'hello.srt' sub file by 3 seconds.
python SubShift.py "C:\subs\hello.srt" 00:00:03
in this example, subtitle will be delayed in 'hello.srt' sub file by 1 hour 3 seconds and 500 milliseconds
python SubShift.py "C:\subs\hello.srt" -1:00:03,500
I tested the script in two file formats .ass and .srt. Other formates are supported because timestamp format in other file formats fall under these two. So make backup before using the script just in case.
