I want to remove these white spots

[TeNSoR]

Hello!

I need to remove these white spots in this DVD. I tried "RemoveSpotsMC2x" but didn't remove it, any idea?

Maybe it's too big for RemoveSpotsMC. RemoveDirtMC gets rid of it:

MPEG2Source("test.d2v")
QTGMC()
Srestore()
RemoveDirtMC(last, 55, false)

I forget what it needs besides the function itself. Probably the same as RemoveSpotsMC. The error message will tell you. Here's the function:

Thanks so much, manono! I will try

Try keeping the limit argument of RemoveDirtMC() as low as possible. The higher it gets the more likely you are to see artifacts (smearing or blurring during motion, removal of spots that are supposed to be there, etc.). Of course, if you set it very low fewer spots will be removed. So you need to strike a balance between spot removal and artifacts.

If you want to spend the time, after calling RemoveDirtMC(), you can locate individual frames with remaining spots and replace them with the frame before, the frame after, or a motion interpolated frame.

Thanks, jagabo for replying, sorry, but how to replace the individual frames with remaining spots with the frame before?
Also I didn't find this filter "RemoveGrainTSSE2.dll"

I believe the RemoveGrainT link at the bottom of this page is the one you want:
http://avisynth.nl/index.php/Removegrain

You can use ReplaceFramesMC() to replace individual frames or several frames in a row. It replaces the frames with motion interpolated frames from the surrounding frames.

######################################################

function ReplaceFramesMC(clip Source, int N, int "X")
{
 # N is number of the 1st frame in Source that needs replacing. 
 # X is total number of frames to replace, 1 if not specified
 #e.g. RX(101, 5) would replace 101,102,103,104,105 , by using 100 and 106 as reference points for mflowfps interpolation
 
 X = Default(X, 1)

 start=Source.trim(N-1,-1) #one good frame before, used for interpolation reference point
 end=Source.trim(N+X,-1) #one good frame after, used for interpolation reference point
 
 start+end
 AssumeFPS(1) #temporarily FPS=1 to use mflowfps
  
 super = MSuper(pel=2, hpad=0, vpad=0, rfilter=4)
 backward_1 = MAnalyse(super, chroma=false, isb=true, blksize=16, searchparam=3, plevel=0, search=3, badrange=(-24))
 forward_1 = MAnalyse(super, chroma=false, isb=false, blksize=16, searchparam=3, plevel=0, search=3, badrange=(-24))
 backward_2 = MRecalculate(super, chroma=false, backward_1, blksize=8, searchparam=1, search=3)
 forward_2 = MRecalculate(super, chroma=false, forward_1, blksize=8, searchparam=1, search=3)
 backward_3 = MRecalculate(super, chroma=false, backward_2, blksize=4, searchparam=0, search=3)
 forward_3 = MRecalculate(super, chroma=false, forward_2, blksize=4, searchparam=0, search=3)
 MBlockFps(super, backward_3, forward_3, num=X+1, den=1, mode=0)

 AssumeFPS(FrameRate(Source)) #return back to normal source framerate for joining
 Trim(1, framecount-1) #trim ends, leaving replacement frames
  
 Source.trim(0,-N) ++ last ++ Source.trim(N+X+1,0)
}

######################################################

This is a slight variation of someone else's function with a different name -- RX() I think it was.

You call it like:

ReplaceFramesMC(100) # replace frame 100
ReplaceFramesMC(205,3) # replace three consecutive frames: 205, 206, and 207

Beware that this type of motion interpolation doesn't always work well. It sometimes leads to weird distortions.

I have two other functions for replacing a frame with a copy of the frame before or the frame after:

######################################################

function ReplaceFrameNext(clip Source, int N)
{
  # Replace frame at N with frame at N+1
  # N is the frame to replace
  # with frame at N+1

  loop(Source, 0, N, N)
  loop(last, 2, N, N)
}

######################################################

function ReplaceFramePrev(clip Source, int N)
{
  # Replace frame at N with frame at N-1
  # N is the frame to replace
  # with frame at N-1

  loop(Source, 0, N, N)
  loop(last, 2, N-1, N-1)
}

######################################################

I recently saw an easier way to do this. I think there is a built in function now. But I don't remember what it is.

Much appreciated!

Excuse me, jagabo, Can I put these codes together or just one of them

ReplaceFramesMC(100) # replace frame 100
ReplaceFramesMC(205,3) # replace three consecutive frames: 205, 206, and 207

Also, How can I call this code :



Thank you!

You can call the function as many times as needed.

[Attachment 40037 - Click to enlarge]

As with any AviSynth function, include them in the body of your code, or save them as an AVS file and import them into your script, or save them as an AVSI file in AviSyth's plugins folder and they'll automatically import every time AviSynth is started. Then call them with:

ReplaceFrameNext(123) # replace frame 123 with a copy of frame 124
ReplaceFramePrev(234) # replace frame 234 with a copy of frame 233

Call them as many times as needed.

You can also use ReplaceFramesMC over just a part of a frame by cropping off what you don't want interpolated. For the frame in your sample, something like this works:

Yadif(Mode=1)#or QTGMC or your favorite bobber
SRestore()
A=Last
B=ReplaceFramesMC(250,2)###the crud in your sample
B=B.Crop(450,0,0,-400)
Overlay(A,B,450,0)

That way, parts that might be moving and which might get artifacted by frame interpolation (Dharmendra moving), aren't affected.

This is amazing! Thank you, guys!
