Then this above SRT file is converted into the below ASS subtitle

Both when playing the subtitle in any video player or burning into video via FFMPEG, what happens is, multiple Dialogue lines are being displayed at the same time on the screen.


I am doing a lot of research regarding this but still couldn't find out the issue.


Here screenshot of what I mean. So how can I fix this issue ? What is wrong with my ASS file format ?




Here below the functio that I am use to generate that ASS format


def convert_srt_to_ass(srt_content):
 # ASS header
 ass_header = (
 "[Script Info]\n"
 "ScriptType: v4.00+\n"

 "[Events]\n"
 "Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text\n"
 )

 ass_content = ass_header
 # Adjust regex to properly capture subtitle number, start time, end time, and text
 matches = list(re.finditer(r'(\d+)\n(\d{2}:\d{2}:\d{2},\d{3}) --> (\d{2}:\d{2}:\d{2},\d{3})\n(.+?)\n\n', srt_content, re.DOTALL))

 prev_end = None
 
 for match in matches:
 start, end, text = match.group(2), match.group(3), match.group(4)
 start = start.replace(',', '.')
 end = end.replace(',', '.')

 # Calculate the correct start and end times to ensure no overlap
 if prev_end and start <= prev_end:
 # Adjust the previous end time to be a bit before the current start time
 prev_end_time = datetime.strptime(prev_end, '%H:%M:%S.%f')
 adjusted_end_time = prev_end_time - timedelta(milliseconds=100) # Adjust by 100 milliseconds
 prev_end = adjusted_end_time.strftime('%H:%M:%S.%f')[:-3] # Truncate to 3 decimal places

 ass_content = ass_content.rstrip()
 ass_content = re.sub(r'(\d{2}:\d{2}:\d{2}\.\d{3}),Default,,$', f'{prev_end},Default,,', ass_content, 1)
 ass_content += '\n'

 prev_end = end

 # Formatting the text and adding it to the content
 text = text.replace('<u>', '{\\c&H00FF00&}').replace('</u>', '{\\c&HFFFFFF&}')
 text = text.replace('\n', '\\N') # Convert newlines within text for ASS format
 ass_content += f"Dialogue: 0,{start},{end},Default,,0,0,0,,{text}\n"

 
 # Conversion of text and other formatting remains the same

 return ass_content
