Bases: GeneralMask

Abstract DeferredMask interface

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.

  • 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.
