[HELP] Fragments disappear in hand-drawn animation
In the new version, the Killshot checkbox is deactivated, it does not work with parameters, crashes. Without parameters, it worked, as I wrote above. And you previously wrote about SMDegrain, Mctemporaldenoise with high values. What values can you recommend for cartoons? On many filters, black contour lines with McLean are thinned. ((Elements of the face, hands) And it also gives an extra blur, compared to others. Mctemporaldenoise works better in this regard. So in several passes, many points are removed, but due to the thinning of the lines (contours of objects), re-encoding spoils the frame.

a. got no recommendation, parameters have to be adjusted
b. you also can use line darkening filters you thicken and darken black lines

McLean -> mClean
#  +++ Description +++
# Typical spatial filters work by removing large variations in the image on a small scale, reducing noise but also making the image less
# sharp or temporally stable. mClean removes noise whilst retaining as much detail as possible, as well as provide optional image enhancement

# mClean works primarily in the temporal domain, although there is some spatial limiting
# Chroma is processed a little differently to luma for optimal results
# Input must be 8-bit Planar type (YV12, YV16, YV24) or their equivalents in 10, 12, 14, or 16 bits
# Chroma processing can be disabled with chroma=false

#  +++ Artifacts +++
# Spatial picture artifacts may remain as removing them is a fine balance between removing the unwanted artifact whilst not removing detail
# Additional dering/dehalo/deblock filters may be required, but should ONLY be uses if required due the detail loss/artifact removal balance

#  +++ Sharpening +++
# Applies a modified unsharp mask to edges and major detected detail. Range of normal sharpening is 0-20, the default 10. There are 4 additional
# settings, 21-24 that provide 'overboost' sharpening. Overboost sharpening is only suitable typically for high definition, high quality sources.
# Actual sharpening calculation is scaled based on resolution.

# +++ ReNoise +++
# ReNoise adds back some of the removed luma noise. Re-adding original noise would be counterproductive, therefore ReNoise modifies this noise
# both spatially and temporally. The result of this modification is the noise becomes much nicer and it's impact on compressibility is greatly
# reduced. It is not applied on areas where the sharpening occurs as that would be counterproductive. Settings range from 1 to 20, default
# value is 14. The strength of renoise is affected by the the amount of original noise removed and how this noise varies between frames. It's
# main purpose is to reduce the 'flatness' that occurs with any form of effective denoising.

# +++ Deband +++
# This will perceptibly improve the quality of the image by reducing banding effect and adding a small amount of temporally stabilised grain to
# both luma and chroma. The settings are not adjustable as the default settings are suitable for most cases without having a large effect on
# compressibility. Auto balance uses Autoadjust, it calculates statistics of the clip, stabilises temporally and adjusts luminance gain & colour
# balance of the noise reduced clip.
# 0=disabled, 1=deband only, 2=auto balance only, 3=both deband and auto balance, 4=deband and veed, 5=all

# +++ Depth +++
# This applies a modified warp sharpening on the image that may be useful for certain things, and can improve the perception of image depth. Default
# is 0 (disabled), and ranges up to 5. This function will distort the image, for animation a setting of 1 or 2 can be beneficial to improve lines. The
# effect

# +++ Strength +++
# The strength of the denoising effect can be adjusted using this parameter. It ranges from 20 percent denoising effect with strength 1, up to the
# 100 percent of the denoising with strength 20 (default). This function works by blending a scaled percentage of the original image with the processed
# image.

# +++ Outbits +++
# Specifies the bits per component (bpc) for the output for processing by additional filters. It will also be the bpc that mClean will process.
# By default, mClean processes as 12 bits if the input is 8 bit, and converts back to 8 bit. If the input is 10 bits or higher no conversion is
# done unless outbits is specified and is different to the input bpc. If you output at a higher bpc keep in mind that there may be limitations

Thanks! Darkening (Toon) works well.
I haven't solved some problems with large spots and scratches in high-resolution cartoons yet. But in general, it looks much better, at least SpotLess can sometimes be used on small episodes with the replacement of damaged frames where there is rapid movement and the boundaries are erased. I hope some other solution to this problem will appear in the future.
