Whether to double the FPS.

dstr class-attribute instance-attribute 

dstr: int = 4

estr class-attribute instance-attribute 

estr: int = 2

Defines the required number of edge pixels (<=) in a 3x3 area, in which the center pixel has been detected as an edge pixel, for the center pixel to be removed from the edge map.

lthresh class-attribute instance-attribute 

lthresh: int = 20

Controls the Laplacian threshold used in edge detection. Its range is from 0 to 510, with lower values detecting weaker lines.

map class-attribute instance-attribute 

map: int = 0

Allows one of three possible maps to be shown: - 0 = no map - 1 = edge map (Edge pixels will be set to 255 and non-edge pixels will be set to 0) - 2 = original scale direction map - 3 = 2x scale direction map

maxd class-attribute instance-attribute 

maxd: int = 24

Sets the maximum pixel search distance for determining the interpolation direction. Larger values allow the algorithm to connect edges and lines with smaller slopes but may introduce artifacts. In some cases, using a smaller maxd value can yield better results than a larger one. The maximum possible value for maxd is 29.

mthresh class-attribute instance-attribute 

mthresh: int = 10

Controls the edge magnitude threshold used in edge detection for building the initial edge map. Its range is from 0 to 255, with lower values detecting weaker edges.

nt class-attribute instance-attribute 

nt: int = 50

Defines the noise threshold between pixels in the sliding vectors. This value is used to determine initial starting conditions. Lower values typically reduce artifacts but may degrade edge reconstruction, while higher values can enhance edge reconstruction at the cost of introducing more artifacts. The valid range is from 0 to 256.

pp class-attribute instance-attribute 

pp: int = 1

Enables two optional post-processing modes designed to reduce artifacts by identifying problem areas and applying simple vertical linear interpolation in those areas. While these modes can improve results, they may slow down processing and slightly reduce edge sharpness. - 0 = No post-processing - 1 = Check for spatial consistency of final interpolation directions - 2 = Check for junctions and corners - 3 = Apply both checks from 1 and 2

Only pp=0 and pp=1 is implemented for the CUDA variant.

scaler class-attribute instance-attribute 

scaler: ComplexScalerLike = Catrom

Scaler used for downscaling and shifting after supersampling.

tff class-attribute instance-attribute 

tff: bool = False

Bases: SuperSampler

Enhanced Edge Directed Interpolation (3rd gen.)

Classes:

  • AADirection –

    Enum representing the direction(s) in which anti-aliasing should be applied.

Methods:

Attributes:

  • alpha (float) –

    Controls the weight given to connecting similar neighborhoods.

  • beta (float) –

    Controls the weight given to the vertical difference created by the interpolation.

  • cost3 (bool) –

    Defines the neighborhood cost function used to measure similarity.

  • double_rate (bool) –

    Whether to double the FPS.

  • gamma (float) –

    Penalizes changes in interpolation direction.

  • mclip (VideoNode | VSFunctionNoArgs[VideoNode, ConstantFormatVideoNode] | None) –

    A mask used to apply edge-directed interpolation only to specified pixels.

  • mdis (int) –

    Sets the maximum connection radius. The valid range is [1, 40].

  • noshift (bool | Sequence[bool]) –

    Disables sub-pixel shifting after supersampling.

  • nrad (int) –

    Sets the radius used for computing neighborhood similarity. The valid range is [0, 3].

  • opencl (bool) –

    Enables the use of the OpenCL variant for processing.

  • scaler (ComplexScalerLike) –

    Scaler used for downscaling and shifting after supersampling.

  • sclip (VideoNode | VSFunctionNoArgs[VideoNode, ConstantFormatVideoNode] | None) –

    Provides additional control over the interpolation by using a reference clip.

  • tff (bool) –

    The field order.

  • transpose_first (bool) –

    Transpose the clip before any operation.

  • ucubic (bool) –

    Determines the type of interpolation used.

  • vcheck (int) –

    Defines the reliability check level for the resulting interpolation. The possible values are:

  • vthresh (tuple[float | None, float | None, float | None] | None) –

    Sequence of three thresholds:

alpha class-attribute instance-attribute 

alpha: float = 0.2

Controls the weight given to connecting similar neighborhoods. It must be in the range [0, 1]. A larger value for alpha will connect more lines and edges. Increasing alpha prioritizes connecting similar regions, which can reduce artifacts but may lead to excessive connections.

beta class-attribute instance-attribute 

beta: float = 0.25

Controls the weight given to the vertical difference created by the interpolation. It must also be in the range [0, 1], and the sum of alpha and beta must not exceed 1. A larger value for beta will reduce the number of connected lines and edges, making the result less directed by edges. At a value of 1.0, there will be no edge-directed interpolation at all.

cost3 class-attribute instance-attribute 

cost3: bool = True

Defines the neighborhood cost function used to measure similarity. - When cost3=True, a 3-neighborhood cost function is used. - When cost3=False, a 1-neighborhood cost function is applied.

double_rate class-attribute instance-attribute 

double_rate: bool = True

Whether to double the FPS.

gamma class-attribute instance-attribute 

gamma: float = 20.0

Penalizes changes in interpolation direction. The larger the value of gamma, the smoother the interpolation field will be between two lines. The range for gamma is [0, ∞]. Increasing gamma results in a smoother interpolation between lines but may reduce the sharpness of edges.

If lines are not connecting properly, try increasing alpha and possibly decreasing beta/gamma. If unwanted artifacts occur, reduce alpha and consider increasing beta or gamma.

mclip class-attribute instance-attribute 

mclip: (
    VideoNode | VSFunctionNoArgs[VideoNode, ConstantFormatVideoNode] | None
) = None

A mask used to apply edge-directed interpolation only to specified pixels. Pixels where the mask value is 0 will be interpolated using cubic linear or bicubic methods instead. The primary purpose of the mask is to reduce computational overhead by limiting edge-directed interpolation to certain pixels.

mdis class-attribute instance-attribute 

mdis: int = 20

Sets the maximum connection radius. The valid range is [1, 40]. For example, with mdis=20, when interpolating the pixel at (50, 10) (x, y), the farthest connections allowed would be between (30, 9)/(70, 11) and (70, 9)/(30, 11). Larger values for mdis will allow connecting lines with smaller slopes, but this can also increase the chance of artifacts and slow down processing.

noshift class-attribute instance-attribute 

noshift: bool | Sequence[bool] = False

Disables sub-pixel shifting after supersampling.

  • bool: Applies to both luma and chroma.
  • Sequence[bool]: First for luma, second for chroma.

nrad class-attribute instance-attribute 

nrad: int = 2

Sets the radius used for computing neighborhood similarity. The valid range is [0, 3]. A larger value for nrad will consider a wider neighborhood for similarity, which can improve edge connections but may also increase processing time.

opencl class-attribute instance-attribute 

opencl: bool = False

Enables the use of the OpenCL variant for processing.

scaler class-attribute instance-attribute 

scaler: ComplexScalerLike = Catrom

Scaler used for downscaling and shifting after supersampling.

sclip class-attribute instance-attribute 

sclip: (
    VideoNode | VSFunctionNoArgs[VideoNode, ConstantFormatVideoNode] | None
) = None

Provides additional control over the interpolation by using a reference clip. If set to None, vertical cubic interpolation is used as a fallback method instead.

tff class-attribute instance-attribute 

tff: bool = False

The field order.

transpose_first class-attribute instance-attribute 

transpose_first: bool = False

Transpose the clip before any operation.

ucubic class-attribute instance-attribute 

ucubic: bool = True

Determines the type of interpolation used. - When ucubic=True, cubic 4-point interpolation is applied. - When ucubic=False, 2-point linear interpolation is used.

vcheck class-attribute instance-attribute 

vcheck: int = 2

Defines the reliability check level for the resulting interpolation. The possible values are: - 0: No reliability check - 1: Weak reliability check - 2: Medium reliability check - 3: Strong reliability check

vthresh class-attribute instance-attribute 

vthresh: tuple[float | None, float | None, float | None] | None = (
    32.0,
    64.0,
    4.0,
)

Sequence of three thresholds: - vthresh[0]: Used to calculate the reliability for the first difference. - vthresh[1]: Used for the second difference. - vthresh[2]: Controls the weighting of the interpolation direction.

AADirection

Bases: IntFlag

Enum representing the direction(s) in which anti-aliasing should be applied.

Attributes:

  • BOTH –

    Apply anti-aliasing in both horizontal and vertical directions.

  • HORIZONTAL –

    Apply anti-aliasing in the horizontal direction.

  • VERTICAL –

    Apply anti-aliasing in the vertical direction.

BOTH class-attribute instance-attribute 

BOTH = VERTICAL | HORIZONTAL

Apply anti-aliasing in both horizontal and vertical directions.

HORIZONTAL class-attribute instance-attribute 

HORIZONTAL = auto()

Apply anti-aliasing in the horizontal direction.

VERTICAL class-attribute instance-attribute 

VERTICAL = auto()

Apply anti-aliasing in the vertical direction.

double_rate class-attribute instance-attribute 

double_rate: bool = True

Whether to double the FPS.

etype class-attribute instance-attribute 

etype: int = 0

The set of weights used in the predictor neural network. Possible values: - 0: Weights trained to minimise absolute error. - 1: Weights trained to minimise squared error.

nns class-attribute instance-attribute 

nns: int = 4

Number of neurons in the predictor neural network. Possible values: - 0: 16 - 1: 32 - 2: 64 - 3: 128 - 4: 256

Wrapper default is 4, plugin default is 1.

noshift class-attribute instance-attribute 

noshift: bool | Sequence[bool] = False

Disables sub-pixel shifting after supersampling.

  • bool: Applies to both luma and chroma.
  • Sequence[bool]: First for luma, second for chroma.

nsize class-attribute instance-attribute 

nsize: int = 0

Size of the local neighbourhood around each pixel used by the predictor neural network. Possible settings: - 0: 8x6 - 1: 16x6 - 2: 32x6 - 3: 48x6 - 4: 8x4 - 5: 16x4 - 6: 32x4

    clip: VideoNodeT,
    rfactor: float = 2.0,
    shift: tuple[TopShift, LeftShift] = (0, 0),
    **kwargs: Any
) -> VideoNodeT

Supersample a clip by a given scaling factor.

Note: Setting tff=True results in less chroma shift for non-centered chroma locations.

Parameters:

  • clip

    (VideoNodeT) –

    The source clip.

  • rfactor

    (float, default: 2.0 ) –

    Scaling factor for supersampling.

  • shift

    (tuple[TopShift, LeftShift], default: (0, 0) ) –

    Subpixel shift (top, left) applied during scaling.

  • kwargs

    (Any, default: {} ) –

    Additional arguments forwarded to the scale function.

Returns:

Raises:

  • CustomValueError –

    If resulting resolution is non-positive.
