Export subtitle duration

[Eranhy]

Hi friends, thanks for the help.


I need to export the "timing" ("duration") of the dialogues of each subtitle.


---------- For example, export from: ----------

1
00:01:10,000 --> 00:01:50,000
Dialogue 1

2
00:07:20,840 --> 00:09:20,845
Dialogue 2


---------- Convert o export to file to result in: ----------

1
00:01:10,000 --> 00:01:50,000 = 00:00:40,000
Dialogue 1

2
00:07:20,840 --> 00:09:20,840 = 00:02:00,005
Dialogue 2


---------- Or also in: ----------
1
00:00:40,000
Dialogue 1

2
00:02:00,005
Dialogue 2

using python, save this file as totaltimes.py:

def sec2time(sec):
    ''' Convert seconds to 'D days, HH:MM:SS.FFF' '''
    m, s = divmod(sec, 60)
    h, m = divmod(m, 60)
    d, h = divmod(h, 24)
    pattern = '%%02d:%%02d:%%0%d.%df' % (6, 3)
    if d == 0:
        return pattern % (h, m, s)
    return (f'{h:d}:{m:02d}:{s:02d}')

def time2sec(time):
    ''' converts HH:MM:SS.FFF or HH:MM:SS,FFF string to seconds '''
    time = time.strip()[:12].replace(',','.')
    h, m, s = map(float, time.split(':'))
    return h * 3600 + m * 60 + s
                      
def main(old_srt, new_srt):             
    with open(old_srt, 'r+') as f, open(new_srt, 'w') as w:
        for line in f:
            if '-->' in line:
                start_sec, end_sec, *_  = map(time2sec, line.split('-->'))
                difference_time = sec2time(end_sec - start_sec).replace('.',',')
                w.write(f'{line[:-1]} = {difference_time}\n')
                #w.write(f'{difference_time}\n') 
            else:
                w.write(line)



if __name__ == '__main__':
    '''
    Using command line:
    python "totaltimes.py" "old.srt" "new.srt"
    '''
    import os
    import sys
    source_paths = []
    if len(sys.argv) > 1:
        for i, path in enumerate(sys.argv[1:]):
            if i < 1 and not os.path.isfile(path):
                raise ValueError(f'Not a valid path or file does not exist: {path}')
            source_paths.append(path)        
        if i < 1:
            raise ValueError(f'Two path arguments needed')
        source_paths = source_paths[0:2]
        source_paths = [os.path.abspath(path)  for path in source_paths]
        main(source_paths[0], source_paths[1])

if using within python:

import totaltimes
from pathlib import Path
original = r"D:/path/my_subtitles.srt"
original = Path(original)
new = original.parent.joinpath(f'new_{original.name}') #just adds "new_" for a new file
totaltimes.main(original, new)

    return (f'{h:d}:{m:02d}:{s:02d}')

Thanks _AI_, thanks for coding.
