Reading and writing subtitles¶
Using path to file¶
-
classmethod
SSAFile.
load
(path: str, encoding: str = 'utf-8', format_: Optional[str] = None, fps: Optional[float] = None, **kwargs) → pysubs2.ssafile.SSAFile¶ Load subtitle file from given path.
This method is implemented in terms of
SSAFile.from_file()
.See also
Specific formats may implement additional loading options, please refer to documentation of the implementation classes (eg.
pysubs2.subrip.SubripFormat.from_file()
)- Parameters
path (str) – Path to subtitle file.
encoding (str) – Character encoding of input file. Defaults to UTF-8, you may need to change this.
format (str) – Optional, forces use of specific parser (eg. “srt”, “ass”). Otherwise, format is detected automatically from file contents. This argument should be rarely needed.
fps (float) – Framerate for frame-based formats (MicroDVD), for other formats this argument is ignored. Framerate might be detected from the file, in which case you don’t need to specify it here (when given, this argument overrides autodetection).
kwargs – Extra options for the reader.
- Returns
SSAFile
- Raises
IOError –
UnicodeDecodeError –
Note
pysubs2 may autodetect subtitle format and/or framerate. These values are set as
SSAFile.format
andSSAFile.fps
attributes.Example
>>> subs1 = pysubs2.load("subrip-subtitles.srt") >>> subs2 = pysubs2.load("microdvd-subtitles.sub", fps=23.976) >>> subs3 = pysubs2.load("subrip-subtitles-with-fancy-tags.srt", keep_unknown_html_tags=True)
-
SSAFile.
save
(path: str, encoding: str = 'utf-8', format_: Optional[str] = None, fps: Optional[float] = None, **kwargs)¶ Save subtitle file to given path.
This method is implemented in terms of
SSAFile.to_file()
.See also
Specific formats may implement additional saving options, please refer to documentation of the implementation classes (eg.
pysubs2.subrip.SubripFormat.to_file()
)- Parameters
path (str) – Path to subtitle file.
encoding (str) – Character encoding of output file. Defaults to UTF-8, which should be fine for most purposes.
format (str) – Optional, specifies desired subtitle format (eg. “srt”, “ass”). Otherwise, format is detected automatically from file extension. Thus, this argument is rarely needed.
fps (float) – Framerate for frame-based formats (MicroDVD), for other formats this argument is ignored. When omitted,
SSAFile.fps
value is used (ie. the framerate used for loading the file, if any). When theSSAFile
wasn’t loaded from MicroDVD, or if you wish save it with different framerate, use this argument. See alsoSSAFile.transform_framerate()
for fixing bad frame-based to time-based conversions.kwargs – Extra options for the writer.
- Raises
IOError –
UnicodeEncodeError –
Using string¶
-
classmethod
SSAFile.
from_string
(string: str, format_: Optional[str] = None, fps: Optional[float] = None, **kwargs) → pysubs2.ssafile.SSAFile¶ Load subtitle file from string.
See
SSAFile.load()
for full description.- Parameters
string (str) – Subtitle file in a string. Note that the string must be Unicode (in Python 2).
- Returns
SSAFile
Example
>>> text = ''' ... 1 ... 00:00:00,000 --> 00:00:05,000 ... An example SubRip file. ... ''' >>> subs = SSAFile.from_string(text)
-
SSAFile.
to_string

classmethod
SSAFile.
from_file
(fp: io.TextIOBase, format_: Optional[str] = None, fps: Optional[float] = None, **kwargs) → pysubs2.ssafile.SSAFile¶ Read subtitle file from file object.
See
SSAFile.load()
for full description.Note
This is a low-level method. Usually, one of
SSAFile.load()
orSSAFile.from_string()
is preferable.- Parameters

instance. Note that the file must be opened in text mode (as opposed to binary).- Returns
SSAFile
-
SSAFile.
to_file
(fp: io.TextIOBase, format_: str, fps: Optional[float] = None, **kwargs)¶ Write subtitle file to file object.
See
SSAFile.save()
for full description.Note
This is a low-level method. Usually, one of
SSAFile.save()
orSSAFile.to_string()
is preferable.- Parameters
fp (file object) – A file object, ie.
io.TextIOBase
instance. Note that the file must be opened in text mode (as opposed to binary).
Retiming subtitles¶
-
SSAFile.

Shift may be time-based (the default) or frame-based. In the latter case, specify both frames and fps. h, m, s, ms will be ignored.
- Parameters
h – Integer or float values, may be positive or negative.
m – Integer or float values, may be positive or negative.
s – Integer or float values, may be positive or negative.
ms – Integer or float values, may be positive or negative.
frames (int) – When specified, must be an integer number of frames. May be positive or negative. fps must be also specified.
fps (float) – When specified, must be a positive number.
- Raises
ValueError – Invalid fps or missing number of frames.
-
SSAFile.
transform_framerate
(in_fps: float, out_fps: float)¶ Rescale all timestamps by ratio of in_fps/out_fps.
Can be used to fix files converted from frame-based to time-based with wrongly assumed framerate.
- Parameters
in_fps (float) –
out_fps (float) –
- Raises
ValueError – Non-positive framerate given.
Working with styles¶
-
SSAFile.
rename_style
(old_name: str, new_name: str)¶ Rename a style, including references to it.
- Parameters
old_name (str) – Style to be renamed.
new_name (str) – New name for the style (must be unused).
- Raises
KeyError – No style named old_name.
ValueError – new_name is not a legal name (cannot use commas) or new_name is taken.
Misc methods¶
-
SSAFile.
remove_miscellaneous_events
()¶ Remove subtitles which appear to be non-essential (the –clean in CLI)
Currently, this removes events matching any of these criteria: - SSA event type Comment - SSA drawing tags - Less than two characters of text - Duplicated text with identical time interval (only the first event is kept)
-
SSAFile.
equals
(other: pysubs2.ssafile.SSAFile)¶ Equality of two SSAFiles.
Compares
SSAFile.info
,SSAFile.styles
andSSAFile.events
. Order of entries in OrderedDicts does not matter. “ScriptType” key in info is considered an implementation detail and thus ignored.Useful mostly in unit tests. Differences are logged at DEBUG level.
-
SSAFile.
sort
()¶ Sort subtitles time-wise, in-place.
SSAEvent
— one subtitle¶
-
class
pysubs2.
SSAEvent
(start: int = 0, end: int = 10000, text: str = '', marked: bool = False, layer: int = 0, style: str = 'Default', name: str = '', marginl: int = 0, marginr: int = 0, marginv: int = 0, effect: str = '', type: str = 'Dialogue')¶ A SubStation Event, ie. one subtitle.
In SubStation, each subtitle consists of multiple “fields” like Start, End and Text. These are exposed as attributes (note that they are lowercase; see
SSAEvent.FIELDS
for a list). Additionaly, there are some convenience properties likeSSAEvent.plaintext
orSSAEvent.duration
.This class defines an ordering with respect to (start, end) timestamps.
Tip
Use
pysubs2.make_time()
to get times in milliseconds.Example:
>>> ev = SSAEvent(start=make_time(s=1), end=make_time(s=2.5), text="Hello World!")
-
property
FIELDS
¶ All fields in SSAEvent.
-
copy
() → pysubs2.ssaevent.SSAEvent¶ Return a copy of the SSAEvent.

-
end
: int = 10000¶ Subtitle end time (in milliseconds)
-
equals
(other: pysubs2.ssaevent.SSAEvent) → bool¶ Field-based equality for SSAEvents.

is_comment
¶ When true, the subtitle is a comment, ie. not visible (read/write property).
Setting this property is equivalent to changing
SSAEvent.type
to"Dialogue"
or"Comment"
.
-
property

(fontname: str = 'Arial', fontsize: float = 20.0, primarycolor: pysubs2.common.Color = Color(r=255, g=255, b=255, a=0), secondarycolor: pysubs2.common.Color = Color(r=255, g=0, b=0, a=0), tertiarycolor: pysubs2.common.Color = Color(r=0, g=0, b=0, a=0), outlinecolor: pysubs2.common.Color = Color(r=0, g=0, b=0, a=0), backcolor: pysubs2.common.Color = Color(r=0, g=0, b=0, a=0), bold: bool = False, italic: bool = False, underline: bool = False, strikeout: bool = False, scalex: float = 100.0, scaley: float = 100.0, spacing: float = 0.0, angle: float = 0.0, borderstyle: int = 1, outline: float = 2.0, shadow: float = 2.0, alignment: int = 2, marginl: int = 10, marginr: int = 10, marginv: int = 10, alphalevel: int = 0, encoding: int = 1, drawing: bool = False)¶ A SubStation Style.
In SubStation, each subtitle (
SSAEvent
) is associated with a style which defines its font, color, etc. Like a subtitle event, a style also consists of “fields”; seeSSAStyle.FIELDS
for a list (note the spelling, which is different from SubStation proper).Subtitles and styles are connected via an
SSAFile
they belong to.SSAEvent.style
is a string which is (or should be) a key in theSSAFile.styles
dict. Note that style name is stored separately; a givenSSAStyle
instance has no particular name itself.This class defines equality (equality of all fields).

FormatBase
¶ Base class for subtitle format implementations.
How to implement a new subtitle format:
Create a subclass of FormatBase and override the methods you want to support.
Decide on a format identifier, like the
"srt"
or"microdvd"
already used in the library.Add your identifier and class to
pysubs2.formats.FORMAT_IDENTIFIER_TO_FORMAT_CLASS
.(optional) Add your file extension and class to
pysubs2.formats.FILE_EXTENSION_TO_FORMAT_IDENTIFIER
.
After finishing these steps, you can call
SSAFile.load()
andSSAFile.save()
with your format, including autodetection from content and file extension (if you provided these).-
classmethod
from_file
(subs, fp: io.TextIOBase, format_: str, **kwargs)¶ Load subtitle file into an empty SSAFile.
If the parser autodetects framerate, set it as
subs.fps
.- Parameters
subs (SSAFile) – An empty
SSAFile
.fp (file object) – Text file object, the subtitle file.
format (str) – Format identifier. Used when one format class implements multiple formats (see
SubstationFormat
).kwargs – Extra options, eg. fps.
- Returns
None
- Raises
pysubs2.exceptions.UnknownFPSError – Framerate was not provided and cannot be detected.
-
classmethod
guess_format
(text: str) → Optional[str]¶ Return format identifier of recognized format, or None.
- Parameters
text (str) – Content of subtitle file. When the file is long, this may be only its first few thousand characters.
- Returns
format identifier (eg.
"srt"
) or None (unknown format)
-
classmethod
to_file
(subs, fp: io.TextIOBase, format_: str, **kwargs)¶ Write SSAFile into a file.
If you need framerate and it is not passed in keyword arguments, use
subs.fps
.- Parameters
subs (SSAFile) – Subtitle file to write.
fp (file object) – Text file object used as output.
format (str) – Format identifier of desired output format. Used when one format class implements multiple formats (see
SubstationFormat
).kwargs – Extra options, eg. fps.
- Returns
None
- Raises
pysubs2.exceptions.UnknownFPSError – Framerate was not provided and
subs.fps is None
.

SubripFormat
¶ SubRip Text (SRT) subtitle format implementation
-
classmethod
from_file
(subs, fp, format_, keep_html_tags=False, keep_unknown_html_tags=False, **kwargs)¶ See
pysubs2.formats.FormatBase.from_file()
Supported tags:
<i>
<u>
<s>
<b>
- Keyword Arguments
keep_html_tags – If True, all HTML tags will be kept as-is instead of being converted to SubStation tags (eg. you will get
<i>example</i>
instead of{\i1}example{\i0}
). Setting this to True overrides thekeep_unknown_html_tags
option.keep_unknown_html_tags – If True, supported HTML tags will be converted to SubStation tags and any other HTML tags will be kept as-is (eg. you would get
<blink>example {\i1}text{\i0}</blink>
). If False, these other HTML tags will be stripped from output (in the previous example, you would get onlyexample {\i1}text{\i0}
).
-
classmethod
guess_format
(text)¶
-
static
ms_to_timestamp
(ms: int) → str¶ Convert ms to ‘HH:MM:SS,mmm’
-
classmethod
to_file
(subs, fp, format_, apply_styles=True, keep_ssa_tags=False, **kwargs)¶ See
pysubs2.formats.FormatBase.to_file()
Italic, underline and strikeout styling is supported.
- Keyword Arguments
apply_styles – If False, do not write any styling (ignore line style and override tags).
keep_ssa_tags – If True, instead of trying to convert inline override tags to HTML (as supported by SRT), any inline tags will be passed to output (eg.
{\an7}
, which would be otherwise stripped; or{\b1}
instead of<b>
). Whitespace tags\h
,\n
and\N
will always be converted to whitespace regardless of this option. In the current implementation, enabling this option disables processing of line styles - you will get inline tags but if for example line’s style is italic you will not get{\i1}
at the beginning of the line. (Since this option is mostly useful for dealing with non-standard SRT files, ie. both input and output is SRT which doesn’t use line styles - this shouldn’t be much of an issue in practice.)
