pyasstosrt 1.5.0

Convert ASS subtitle to SRT format

pyasstosrt

pyasstosrt – this tool will help you convert Advanced SubStation Alpha (ASS/SSA) subtitle files to SubRip (SRT) files.

Support for str path:

from pyasstosrt import Subtitle

sub = Subtitle('sub.ass')
sub.export()

Support for all Path-like objects, instead of only pathlib's Path:

from pathlib import Path

from pyasstosrt import Subtitle

path = Path('sub.ass')
sub = Subtitle(path)
sub.export()

You can get a sheet with dialogue by specifying output_dialogues.

from pathlib import Path

from pyasstosrt import Subtitle

path = Path('sub.ass')
sub = Subtitle(path)
sub.export(output_dialogues=True)

If you want to remove effects from text, you can use the removing_effects.

from pyasstosrt import Subtitle

sub = Subtitle('sub.ass', removing_effects=True)
sub.export()

You can enable the deletion of duplicate lines with the rearrangement of start and end times.

from pyasstosrt import Subtitle

sub = Subtitle('sub.ass', remove_duplicates=True)
sub.export()

You can get a list of all styles in the file and filter subtitles by style names.

from pyasstosrt import Subtitle

# Get list of all styles in the file
sub = Subtitle('sub.ass')
styles = sub.get_styles()
print(styles)  # ['Default', 'Alt', 'Signs', 'Credits']

# Export only styles with "Default" in name (e.g., Default, Default_dvd)
sub = Subtitle('sub.ass', only_default_style=True)
sub.export()

# Export only Default style
sub = Subtitle('sub.ass', include_styles=['Default'])
sub.export()

# Export only Default and Alt styles
sub = Subtitle('sub.ass', include_styles=['Default', 'Alt'])
sub.export()

# Exclude Signs and Credits styles
sub = Subtitle('sub.ass', exclude_styles=['Signs', 'Credits'])
sub.export()
