Bases: HardsubMask

A helper for de-hardsubbing using an ASS subtitle file to generate a hardsub mask.

Parameters:

  • filename

    (FilePathType) –

    Subtitle file.

  • ranges

    (FrameRangeN | FrameRangesN | None, default: None ) –

    The frame ranges that the mask should be applied to.

  • bound

    (BoundingBox | None, default: None ) –

    An optional bounding box that defines the area of the frame where the mask will be applied. If None, the mask applies to the whole frame.

  • blur

    (bool, default: False ) –

    Whether to apply a box blur effect to the mask.

  • refframes

    (int | list[int | None] | None, default: None ) –

    A list of reference frames used in building the final mask for each specified range. Must have the same length as ranges.

Bases: HardsubMask

Helper for de-hardsubbing white text with black border subtitles. Originally written by Kageru from Kagefunc: https://github.com/Irrational-Encoding-Wizardry/kagefunc

Parameters:

  • ranges

    (FrameRangeN | FrameRangesN | None, default: None ) –

    The frame ranges that the mask should be applied to.

  • bound

    (BoundingBox | None, default: None ) –

    An optional bounding box that defines the area of the frame where the mask will be applied. If None, the mask applies to the whole frame.

  • expand

    (int | None, default: None ) –

    std.Maximum iterations. Default is automatically adjusted based on the width of the clip.

  • blur

    (bool, default: False ) –

    Whether to apply a box blur effect to the mask.

  • refframes

    (int | list[int | None] | None, default: None ) –

    A list of reference frames used in building the final mask for each specified range. Must have the same length as ranges.

    (FrameRangeN | FrameRangesN | None, default: None ) –

    The frame ranges that the mask should be applied to.

  • bound

    (BoundingBox | None, default: None ) –

    An optional bounding box that defines the area of the frame where the mask will be applied. If None, the mask applies to the whole frame.

    Binarization threshold, [0, 1] (Default: 0.06).

  • minimum

    (int, default: 1 ) –

    std.Minimum iterations (Default: 1).

  • expand

    (int, default: 8 ) –

    std.Maximum iterations (Default: 8).

  • inflate

    (int, default: 7 ) –

    std.Inflate iterations (Default: 7).

  • expand_mode

    (XxpandMode, default: RECTANGLE ) –

    Specifies the XxpandMode used for mask growth (Default: XxpandMode.RECTANGLE).

  • blur

    (bool, default: False ) –

    Whether to apply a box blur effect to the mask.

  • refframes

    (int | list[int | None] | None, default: None ) –

    A list of reference frames used in building the final mask for each specified range. Must have the same length as ranges.

Bases: HardsubMask

Helper for hardsub scene filtering, typically used for de-hardsubbing signs during fades or hard-to-catch signs. Originally written by Kageru from Kagefunc: https://github.com/Irrational-Encoding-Wizardry/kagefunc

Parameters:

  • ranges

    (FrameRangeN | FrameRangesN | None, default: None ) –

    The frame ranges that the mask should be applied to.

  • bound

    (BoundingBox | None, default: None ) –

    An optional bounding box that defines the area of the frame where the mask will be applied. If None, the mask applies to the whole frame.

  • highpass

    (float, default: 0.0763 ) –

    Highpass threshold. Lower this value if the sign isn't fully de-hardsubbed, but be cautious as it may also capture more artifacts.

  • expand

    (int, default: 8 ) –

    Number of expand iterations.

  • edgemask

    (GenericMaskT, default: SobelStd ) –

    Edge mask used for finding subtitles.

  • expand_mode

    (XxpandMode, default: RECTANGLE ) –

    Specifies the XxpandMode used for mask growth

  • blur

    (bool, default: False ) –

    Whether to apply a box blur effect to the mask.

  • refframes

    (int | list[int | None] | None, default: None ) –

    A list of reference frames used in building the final mask for each specified range. Must have the same length as ranges.
