how to Synchronizing multi subtitles to another List in Python

[D.LUFFY]

It has 100 asynchronous Subtitles in Indonesian and 100 Synchronized Subtitles into English

Is there a script that adjusts the subtitle of the first line to be synchronous

SUB.Indonesian.srt

1
00:00:02,040 --> 00:00:04,410
"Episode Satu"

2
00:00:05,179 --> 00:00:07,610
"Tujuh tahun lalu"

3
00:00:23,859 --> 00:00:25,800
Ada apa? Kenapa kalian tidak memakai baju olahraga?

SUB.English.srt

1
00:00:07,551 --> 00:00:09,920
(Episode 1)

2
00:00:10,691 --> 00:00:13,231
(7 years ago)

3
00:00:29,440 --> 00:00:31,381
What's going on?
Why aren't you in your gym clothes?

after.sync.srt

1
00:00:07,551 --> 00:00:09,921
"Episode Satu"

2
00:00:10,690 --> 00:00:13,121
"Tujuh tahun lalu"

3
00:00:29,370 --> 00:00:31,311
Ada apa? Kenapa kalian tidak memakai baju olahraga?

batch
SUB.English_%%x.srt SUB.Indonesian_%%x.srt after.sync_%%x.srt

I know a Subtitle Edit , but it only works with one subtitle

All I need is sync from the first line only. Using Python Any suggestions?

this is an example calling for one pair, that could be fed from something, not sure how you store those srt's

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):
    time = time.replace(',','.')
    h, m, s = map(float, time.split(':'))
    return h * 3600 + m * 60 + s

def get_first_time(filename):
    with open(filename, 'r+') as f:
        for line in f:
            if '-->' in line:
                time = line.split('-->')[0].strip()
                return time2sec(time)
                      
def sync_first_sub(used_subtitles_srt, for_first_time_srt, new_srt):
    delay_in_sec = get_first_time(for_first_time_srt) - get_first_time(used_subtitles_srt)
                
    with open(used_subtitles_srt, 'r+') as f, open(new_srt, 'w') as w:
        for line in f:
            if '-->' in line:              
                new_start_sec  = time2sec(line.split('-->')[0].strip()) + delay_in_sec 
                new_start_time = sec2time(new_start_sec).replace('.',',')
                new_end_sec  = time2sec(line.split('-->')[1].strip()) + delay_in_sec 
                new_end_time = sec2time(new_end_sec).replace('.',',')
                w.write(new_start_time+ ' --> ' + new_end_time + '\n')
            else:
                w.write(line)
        
sync_first_sub(used_subtitles_srt=r'F:\path\SUB.Indonesian.srt',
               for_first_time_srt=r'F:\path\SUB.English.srt',
               new_srt=r'F:\path\after_sync.srt')

After trying, an error message appears

If you do a script that works on which path is better

Example


batch

echo off

sync.py  "SUB.Indonesian.srt" "SUB.English.srt"  "after_sync.srt"  

pause

[_Al_]

you need three full correct paths for that script when calling sync_first_sub function
How do you have those srt's in your folder or folders and how are they named?

echo off

sync.py  "SUB.Indonesian.srt" "SUB.English.srt"  "after_sync.srt"  

pause

for that to make it work, instead of that calling sync_first_sub() you can paste::

if __name__ == '__main__':
    import os
    import sys
    source_paths = []
    if len(sys.argv) > 1:
        for i, path in enumerate(sys.argv[1:]):
            if i < 2 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 < 2:
            raise ValueError(f'Three path arguments needed')
        source_paths = source_paths[0:3]
        source_paths = [os.path.abspath(path)  for path in source_paths]
        sync_first_sub(source_paths[0], source_paths[1], source_paths[2])

Thanks bro, it works
