Here is the most optimal AviSynth script, which uses MVTools v.2 with SpotRemover:
LoadPlugin("F:\DGMPGDec\DGDecode.dll")
LoadPlugin("F:\AviSynth\plugins\mvtools2.dll")
LoadVirtualDubPlugin("F:\VirtualDub\plugins\SpotRemover.vdf","SpotRemover",11)
source = mpeg2source("F:\1\dv.d2v")
source
super = MSuper(pel=1, sharp=0)
b_vec2 = MAnalyse(super, isb = true, delta = 2, blksize=4, overlap=2)
b_vec1 = MAnalyse(super, isb = true, delta = 1, blksize=4, overlap=2)
f_vec1 = MAnalyse(super, isb = false, delta = 1, blksize=4, overlap=2)
f_vec2 = MAnalyse(super, isb = false, delta = 2, blksize=4, overlap=2)
bf2 = MCompensate(super, b_vec2)
bf1 = MCompensate(super, b_vec1)
ff1 = MCompensate(super, f_vec1)
ff2 = MCompensate(super, f_vec2)
interleave( bf2, bf1, source, ff1, ff2 )
ConvertToRGB32()

Thanks to a request by Filip who was trying to clean his old 8mm films,
I found a nice combination of filters that recovers the original progressive sequence with no duplicate frames (well, almost).
This helps very much to the subsequent detection of spots by SpotRemover.
You can download examples of the AviSynth scripts with the original video sample, the one cleaned by SpotRemover, as well as the required
filters here (2,139 kb).

(version 3.5.6)
Updated the filter to enable processing of the HDTV 1080p material without problems.
|
03/11/2009
|
(version 3.5.5)
Fixed a bug that caused spontaneous crashes in the
configuration dialog window.
|
|
The code is now compiled with Intel C++ Compiler for better performance.

Added another example of the AviSynth script with SpotRemover filter (see 04/12/2007).
Now there are two versions: one with temporal noise smoothing and one without.
If you also need to suppress the film grain, you should replace the line
interleave(...)
with this one:
interleave( bf2, bf1, SRC.MVDegrain2(b_vec2,b_vec1,f_vec1,f_vec2,plane=4,thsad=400,idx=1), ff1, ff2 )
And here is a couple of movie samples demonstrating the efficiency of restoration of the damaged films, even with
an intensive motion.
Each example has the original version (before filtering) and the filtered one.

Here are two examples of the AviSynth scripts that combine MVtools with SpotRemover:
Spot removal and temporal smoothing at the same time:
LoadPlugin("F:\DGMPGDec\DGDecode.dll")
LoadPlugin("F:\AviSynth\mvtools.dll")
LoadVirtualDubPlugin("F:\VirtualDub\plugins\SpotRemover.vdf","SpotRemover",11)

b_vec1 = FLT.MVAnalyse(isb = true, delta = 1, idx=1)
f_vec1 = FLT.MVAnalyse(isb = false, delta = 1, idx=1)
f_vec2 = FLT.MVAnalyse(isb = false, delta = 2, idx=1)
bf2 = SRC.MVCompensate(vectors=b_vec2, idx=2)
bf1 = SRC.MVCompensate(vectors=b_vec1, idx=2)
ff1 = SRC.MVCompensate(vectors=f_vec1, idx=2)

I found an interesting and efficient method of cleaining the old film dust
by combining my SpotRemover filter with the MVTools package by
Fizick. His filter does an excellent job at motion compensation, which greately simplifies the subsequent detection of spots by SpotRemover.
The result is quite impressive. Here is a quick look:
|
v.3.5.4
06/18/2003
|
Added support for interlaced video.
However, processing of telecined video is not recommended. Read F.A.Q.
|
|
Minimal kernel size (for smoothing) is reduced to 3 for a faster preview.
|
|
Fixed bug produced "illegal instruction" error on Cyrix(VIA) CPUs.
|
|
Fixed bug caused image shift when attempting to process odd width frames.
|
|
Fixed bug caused occasional memory crashes reported by a few users.
|
v.3.5.3
05/11/2003
|
|
Fixed bug with switching "Interrupted motion history" flag
from script files.
|
|
Fixed bug when the last spot in the motion history chain
was not marked moving while "Interrupted motion history" was set.
|
|
Fixed bug with the display of percentage of saturated pixels when
preview is turned off.
|
v.3.5.2
05/04/2003
|
|
Added a checkbox in "Color" tab to bypass color correction for Preview.
|
|
Added "percentage of saturated pixels" to help finding the optimal
color correction settings.
|
|
No more time lag in preview window when changing frames.
|
|
The effect of Brightness, Contrast, and Saturation sliders is doubled.
|
|
Fixed compatibility issue with Hue/Saturation/Intensity filter.
|
v.3.5.1
03/19/2003
|
Since this release, SpotRemover.vdf module contains all three versions
of the code with different level of optimization:
1) MMX instructions;
2) MMX and CMOVxx instructions;
3) MMX, CMOVxx, and integer SSE instructions.
The appropriate code is automatically activated at startup based on CPU detection.
The optimization level is reported in VirtualDub's list of filters.
|
Now pixels in a spot are replaced by default with the average of the previous and the
next frames.
In script files, it is possible to specify which frame to use
(previous, next or the average of both).
|
|
Fixed problems with dialog metrics at different system font sizes.
|
|
Fixed the crash on the dialog startup at certain conditions.
|
v.3.5.0
03/14/2003
|
|
New configuration options for "Basic" setup.
|
|
New checkbox to allow interrupted history of spot's motion tracking.
|
|
New color control: "Saturation Balance".
|
|
Preview window has no more time lag during color adjustments.
|
New "tabbed" interface.
Tab switching shortcut keys: Ctrl-(Shift)Tab or Ctrl-PgUp/Dn.
If shown, the Help window is synchronized during the tab switching.
Input focus is automatically restored to the last used Tab and Control.
Help pop-ups are invoked by mouse hovering.
|
All configuration parameters can be changed from script files.
Script files may have comments (lines not beginning with a number).
|
The format of the configuration strings of VirtualDub's
VCF and JOBS
files has changed. Old format is still supported. To use your old
VCF and JOBS files you only need to replace the line
VirtualDub.video.filters.Add("SpotRemover (3.4.2)");
with
VirtualDub.video.filters.Add("SpotRemover (3.5)");
|
|
03/12/2003
|
|
FAQ updated. Added topics about processing
interlaced sources and 8-mm film captures.
|
v.3.4.2
01/26/2003
|
|
Motion distances are now input as percents of the frame size.
|
|
Added new mode for script file to change main parameters
of the spot removal at specified frames.
|
|
Fixed the case when restoring defaults resulted in the lost script
file name.
|
|
Minor optimizations in spot detection routine.
|
v.3.4.1
01/24/2003
|
|
Maximal amount of spots per frame is now 96 (was 48).
|
|
Smoothing module was rearranged. Now the Kernel width
can be as low as 5 (was 9) for faster processing or debugging.
|
|
Rounding in integer division is now more correct (from viewpoint of math).
Its accuracy is about 0.4 of intensity step (which is 0...255).
The drawback is that MMX_Only and the MMX+SSE versions do not
produce identical results (MMX_Only uses special tricks to
implement unsigned multiply, see below 2.0.1).
|
|
Spots within the cell with motion (or just touching its edge)
are now marked as moving.
|
|
Motion table size increased to 24x18 (was 14x10).
Optimized processing of the motion table.
Optimized intensity difference comparison.
|
|
Added new modes for script files to change motion threshold
and color controls at specified frames.

older versions.
