adenoise

Designed specifically for film content, this intensive adaptive denoiser removes noise while carefully preserving fine textures and small elements. It combines mc_degrain (luma), NLMeans/CBM3D (chroma), and BM3D (luma), all modulated by adaptive masking.

Presets:

• scan65mm (Light)
• scan35mm (Medium)
• scan16mm (Heavy)
• scan8mm (Very Heavy)
• digital (Optimized for digital sources)
• default (Generic)

Parameters:

adenoise.default(
  clip: vs.VideoNode, 
  thsad: int = 500, 
  tr: int = 2, 
  sigma: float = 6, 
  luma_mask_weaken: float = 0.75, 
  luma_mask_thr: float = 0.196, 
  chroma_denoise: float | str | tuple[float, str] = [1.0, "nlm"], 
  precision: bool = True, 
  chroma_masking: bool = False, 
  luma_over_texture: float = 0.4, 
  kwargs_flatmask: dict = {},
  show_mask: int = 0
)

• clip: Clip to process (YUV or GRAY).

• thsad: Luma and chroma ref denoise strength. Recommended values: 300-800

• tr: Temporal radius for temporal consistency. Recommended values: 2-3 (1 means no temporal denoise).

• sigma: Sigma for BM3D (luma denoise strength). Recommended values: 2-10.

• luma_mask_weaken: Controls how much dark spots should be denoised. Lower values mean stronger overall denoise. Recommended values: 0.6-0.9

• luma_mask_thr: Threshold that determines what is considered bright and what is dark in the luma mask. Recommended values: 0.15-0.25

• chroma_denoise: Denoiser strength and type for chroma. NLMeans/CBM3D/ArtCNN. Reccomended strength values: 0.5-2. Accepted denoiser types: "nlm", "cbm3d", "artcnn".

• precision: If True, a flat mask is created to enhance the denoise strenght avoiding textured area.

• chroma_masking: If True, enables specific chroma masking for U/V planes.

• luma_over_texture: Lower value means more importance to textured areas, higher value means more importance to luma levels. Accepted values: 0.0-1.0

• kwargs_flatmask: Additional arguments. dict values (check hd_flatmask's docstring for more info):

  • sigma1: This value should be decided based on the details level of the clip and how much grain and noise is present. Recommended values: 1-5
  • texture_strength: Texture strength for mask (0-inf). Values above 1 decrease the strength of the texture in the mask.
  • edges_strength: Edges strength for mask (0-1). Basic multiplier for edges strength.

• show_mask: 1 = First luma mask, 2 = Textured luma mask, 3 = Complete luma mask, 4 = Show the Chroma U Plane mask (if chroma_masking = True), 5 = Show the Chroma V Plane mask (if chroma_masking = True).

• return: 16bit denoised clip. If show_mask is set, returns a tuple (denoised_clip, mask).

Usage:

from vsdirty import adenoise

denoised = adenoise.scan16mm(clip)

bore

A powerful edge cleaner (dirty line fixer) that processes borders at their native resolution to avoid scaling artifacts.

Parameters:

def bore(
  clip : vs.VideoNode,
  ythickness: List[int] = None,
  uthickness: List[int] = None,
  vthickness: List[int] = None,
  planes: PlanesT = 0,
  singlePlane = True
)

• clip: Input clip (YUV or GRAY).
• ythickness: Luma border thicknesses to process. [top, bottom, left, right].
• uthickness: Chroma U border thicknesses to process. [top, bottom, left, right].
• vthickness: Chroma V border thicknesses to process. [top, bottom, left, right]. If None, uses ythickness or uthickness.
• planes: Plane(s) to process.
• singlePlane: If True uses bore.SinglePlane, otherwise bore.MultiPlane. MultiPlane works only on 444 clips.
• return: Processed clip with corrected borders, same format as input.

Usage:

from vsdirty import bore

# Fix dirty lines: Top=1px, Bottom=1px, Left=2px, Right=2px
clean = bore(clip, ythickness=[1, 1, 2, 2])

msaa2x

An antialiaser based on ArtCNN that targets edges.

Parameters:

def msaa2x(
    clip: vs.VideoNode,
    ref: Optional[vs.VideoNode] = None,
    mask: bool = False,
    sigma: float = 2,
    thr: float = None,
    planes: PlanesT = 0,
    **kwargs
)

• clip: Clip to process (YUV or GRAY).
• ref: Reference clip used to create the edgemask (clean and denoised).
• mask: If True will return the mask used.
• sigma: Sigma used for edge fixing during antialiasing only if ref is None.
• thr: Threshold used for Binarize the clip, only 0-1 value area allowed. If None, no Binarize will be applied.
• planes: Which planes to process. Defaults to Y.
• kwargs: Accepts advanced_edgemask arguments.

Usage:

from vsdirty import msaa2x

aa_clip = msaa2x(clip)

advanced_edgemask

Generates a high-quality edge mask by combining Retinex preprocessing with multiple edge detectors (Kirsch, Sobel) to capture faint and complex edges.

from vsdirty import admask

emask = admask.advanced_edgemask(clip, luma_scaling=10)

hd_flatmask

A specialized mask for flat areas, useful for protecting textures or targeting specific flat regions for filtering.

from vsdirty import admask

flat_mask = admask.hd_flatmask(clip)

diff_and_swap

A utility to repair damaged frames in a "base" clip using a "correction" clip. It compares frames and swaps them if the difference exceeds a threshold.

from vsdirty import adutils

# automated patching
repaired, _ = adutils.diff_and_swap(correction_clip, base_clip, thr=30000)
