Examples:

import mvsfunc as mvf

# Any input depth
clip = mvf.Depth(clip, depth=16)
# 16-bit integer output

# Any input depth
clip = mvf.Depth(clip, depth=32)
# 32-bit float output

# Any input format
clip = mvf.ToYUV(clip, css="420")
# YUV420P output

# Any input format
clip = mvf.ToRGB(clip, depth=8)
# RGB24 output (e.g. for previewing using vsedit)

# Faster way to preview with RGB24 output, for vsedit
clip = mvf.Preview(clip)

# Preview with CompatBGR32 output, for VirtualDub, AvsPmod, etc.
clip = mvf.Preview(clip, compat=True)

# Compare multiple clips, they will be interleaved into one clip
clip = mvf.Preview([clip1, clip2, clip3])

# Any input format
clip = mvf.BM3D(clip, sigma=[3,3,3], radius1=0) # radius1=0 for BM3D, radius1>0 for V-BM3D
# Same as input format

Mainly some wrap functions, with which it's much simpler to use some functions, especially the BM3D denoising filter, with high internal precision and high quality format conversions.
It's written a few months ago, now finally publish it here. (I thought I should merge nnedi3_resample into it but I'm just too lazy to touch that monster...)

my vapoursynth editor crashes when I do this. The error message said "instruction at 0xe744677c referenced memory at 0x00000020. The memory could not be read".

clip = mvf.BM3D(clip, sigma=[0,0,0], radius1=1)

[mawen1250]

Thanks for your reporting.

Practically, it doesn't make sense when sigma is 0 for all planes (theoretically no processing).
Moreover, for V-BM3D, it probably doesn't have an elegant and efficient way to pass through unprocessed planes.

So for BM3D plugin, I won't do anything to deal with sigma=0.
But for mvf.BM3D, it is easy to skip calling BM3D internally, and here's the fix.

[mawen1250]

Update r7

Depth: now prefer fmtc.bitdepth for full range content
Depth, ToRGB, ToYUV, BM3D, zDepth: new argument "prefer_props"
ToRGB: new argument "compat" to support CompatBGR32 output
***EXPERIMENTAL*** Added Utility function CheckMatrix()
Added Utility function postfix2infix()
Added Helper function GrayScale()
Added Helper function Preview()

[mawen1250]

Update r8

New Main function VFRSplice()
Preview: Set default dither to "random" to avoid banding
Depth, ToRGB, ToYUV, BM3D: When sample conversion is required but 'depth' is not set, use 16-bit for integer and 32-bit for float
LimitFilter: fixed error when thr>0&brighten_thr<=0 or thr<=0&brighten_thr>0
LimitFilter: fixed brighten_thr is not used when elast<=1
Frame properties related fixes

Can you add a "show noise" option for BM3D for each plane? I wanted to know how much noise did I remove

That should be easy to do with std.MakeDiff and hist.Luma (or write an Expr directly).
However this is not a part of the BM3D procedure itself, so I won't add it to the function.

It's a better choice to have a separate function to do the job.
Since the procedure is quite simple, and there're many ways to adjust the difference clip, I couldn't see the convenience to write a function for it...

I wanted something that's a simple on/off switch to show the noise. I'm going to use it repeatedly so I don't want to go through the hassle of commenting/uncommenting lines of codes every time to do this.

And it's not uncommon for denoise filter to have a show noise option, most of the denoise filters in virtualdub have had a show noise option built in on the same UI. It's just more convenience.

You could always wrap it into a function with a "show_noise" parameter.
