) -> list[tuple[int, int]]
Invert FrameRanges.
Example:
>>> franges = [(100, 200), 600, (1200, 2400)]
>>> invert_ranges(core.std.BlankClip(length=10000), core.std.BlankClip(length=10000), franges)
[(0, 99), (201, 599), (601, 1199), (2401, 9999)]
Parameters:
-
clipa
¶VideoNode
) –Original clip.
-
clipb
¶VideoNode | None
) –Replacement clip.
-
ranges
¶FrameRangeN | FrameRangesN
) –Ranges to replace clipa (original clip) with clipb (replacement clip). These ranges will be inverted. For more info, see
replace_ranges
. -
exclusive
¶bool | None
, default:None
) –Whether to use exclusive (Python-style) ranges. Defaults to False.

normalize_param_planes ¶
normalize_param_planes(
clip: VideoNode,
param: T | Sequence[T],
planes: PlanesT,
null: T,
func: FuncExceptT | None = None,
) -> list[T]
Normalize a value or sequence to a list mapped to the clip's planes.
For any plane not included in planes
, the corresponding output value is set to null
.
Parameters:
-
clip
¶VideoNode
) –The input clip whose format and number of planes will be used to determine mapping.
-
param
¶T | Sequence[T]
) –A single value or a sequence of values to normalize across the clip's planes.
-
planes
¶PlanesT
) –The planes to apply the values to. Other planes will receive
null
. -
null
¶T
) –The default value to use for planes that are not included in
planes
. -
func
¶FuncExceptT | None
, default:None
) –Function returned for custom error handling.
Returns:
-
list[T]
–A list of length equal to the number of planes in the clip, with
param
values ornull
.

normalize_planes ¶
Normalize a sequence of planes.
Parameters:

clip
¶VideoNode
) –Input clip.

normalize_ranges ¶
normalize_ranges(
clip: VideoNode,
ranges: FrameRangeN | FrameRangesN,
exclusive: bool | None = None,
) -> list[tuple[int, int]]
Normalize ranges to a list of positive ranges.
Frame ranges can include None
and negative values. None will be converted to either 0 if it's the first value in a FrameRange, or the clip's length if it's the second item. Negative values will be subtracted from the clip's length.
Examples:
>>> clip.num_frames
1000
>>> normalize_ranges(clip, (None, None))
[(0, 999)]
>>> normalize_ranges(clip, (24, -24))
[(24, 975)]
>>> normalize_ranges(clip, [(24, 100), (80, 150)])
[(24, 150)]
Parameters:
-
clip
¶VideoNode
) –Input clip.
-
ranges
¶FrameRangeN | FrameRangesN
) –Frame range or list of frame ranges.
-
exclusive
¶bool | None
, default:None
) –Whether to use exclusive (Python-style) ranges. Defaults to False.
