Please suggest a good deinterlacer for DVD source

[navarannan]

Hi Im trying to de interlace a DVD source, using AVISynth filters in MEGUI
Here is a sample clip
sample.vob

I tried

ord = last.getparity() ? 1 : 0
leakkernelbob(order=ord,threshold=6)
Srestore()
vinverse()

But this has resulted in jerks.
Am I doing something wrong here?

If not could you please suggest a proper filter.(like Yadif, Tdeint, Tfm etc).

Note:- Im not quite sure why I used Srestore() and vinverse(), a friend just gave me...

[davexnet]

Can you provide a small sample? If so, open the source in DGindex, use the [ and ] to set the start and end points,
and try to find a clip with steady movement.
File/save project and demux video
upload the m2v to the thread

Something like this to give 25 FPS. If you want 23.976, you can slow down the video and audio.

Load_Stdcall_plugin("J:\StaxRip_1.1.7.2\Applicatio ns\AviSynth plugins\Yadif\Yadif.dll")
import("F:\Program Files\AviSynth\plugins\srestore.avs")
mpeg2source("C:\Users\davex\Desktop\avs_test\sampl e.d2v")
yadif(mode=1,order=1)
srestore()

Thanks
I have done my first encode with my limited knowledge

I would like to know feedback of experts here.

Basically this is what I did

Import("D:\Plugins\Srestore.avsi")
LoadPlugin("D:\Plugins\vinverse.dll")
LoadPlugin("D:\Plugins\Deblock.dll")
LoadPlugin("D:\Plugins\MSharpen.dll")
LoadPlugin("D:\Plugins\LeakKernelDeint.dll")
LoadPlugin("D:\Plugins\mt_masktools.dll")
LoadPlugin("D:\Plugins\degrainmedian.dll")
LoadPlugin("D:\Plugins\removegrain.dll")
LoadPlugin("D:\Plugins\RepairS.dll")
LoadCPlugin("D:\Plugins\Yadif.dll")
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", info=3)
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
yadif(mode=1,order=1)
Srestore()
vinverse()
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
degrainmedian(mode=4)
MSharpen(threshold=10, strength=100, highq=true, mask=false)
Tweak(sat=1.1)
Deblock(quant=25, aOffset=0, bOffset=0)
#denoise

The source is in the first post.
And here is the encode...
Encode.mp4
Any suggestion on how to improve...

Load_Stdcall_plugin("J:\StaxRip_1.1.7.2\Applicatio ns\AviSynth plugins\Yadif\Yadif.dll")

yadif(mode=1,order=1)
srestore()

yadif? Why?

An encoder from a well known group said he usually uses leakYadif, Tdeint, Tfm apart from leakkernelbob.
Is there any better way, kindly advise

[jagabo]

I would use mpeg2source's deringing, deblock_qed() for deblocking. Alternatives to Yadif(mode=1, order=1) include QTGMC(preset="fast") or Interleave(TFM(field=GetParity()?1:0), TFM(field=GetParity()?0:1)). I'd put vinverse() before srestore() (not needed if you use QTGMC). And run a good noise reducer. Maybe:

Mpeg2Source("sample.d2v", CPU2="ooooxx", Info=3) 
AssumeTFF()
Deblock_QED_i(quant1=24, quant2=28) # edge, internal
QTGMC(preset="fast", EZDenoise=1.0, DenoiseMC=true)
SRestore()

deblock_qed_i():

function Deblock_QED_i ( clip clp, int "quant1", int "quant2", 
 \                     int "aOff1", int "bOff1", int "aOff2", int "bOff2", int "uv" )
{

quant1 = default( quant1, 24 ) # Strength of block edge deblocking
quant2 = default( quant2, 26 ) # Strength of block internal deblocking

aOff1 = default( aOff1, 1 ) # halfway "sensitivity" and halfway a strength modifier for borders
aOff2 = default( aOff2, 1 ) # halfway "sensitivity" and halfway a strength modifier for block interiors
bOff1 = default( bOff1, 2 ) # "sensitivity to detect blocking" for borders
bOff2 = default( bOff2, 2 ) # "sensitivity to detect blocking" for block interiors

uv    = default( uv, 3 )    # u=3 -> use proposed method for chroma deblocking
                            # u=2 -> no chroma deblocking at all (fastest method)
                            # u=1|-1 -> directly use chroma debl. from the normal|strong deblock()

last=clp
par=getparity()
SeparateFields().PointResize(width,height)
Deblock_QED(last, quant1, quant2, aOff1, aOff2, bOff1, bOff2, uv)
AssumeFrameBased()
SeparateFields()
Merge(SelectEven(),SelectOdd())
par ? AssumeTFF() : AssumeBFF()
Weave() 
}

Im completely confused on dependencies.
From Avisynth wiki I have loaded dependencies
But script shows many errors

The error messages , are they the javascript pop ups you get when you load the script?

[manono]

You load the script into VDub. Then you provide both the complete AviSynth script and the error message VDub gives you.

An encoder from a well known group said he usually uses leakYadif, Tdeint, Tfm apart from leakkernelbob.

Your encoder friend is probably ten years out of date.

Here is what I did. As this is the first time Im doing this, please excuse unwanted details...

Initial script

LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", info=3)
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
#denoise

1. Changed Mpeg2Source to include "CPU2="ooooxx"" and reload success
2. Added "AssumeTFF()" and reload success
3. Added "Deblock_QED_i(quant1=24, quant2=28) # edge, internal" and reloaded to receive error.


So I have copied the deblock_qed_i(): Code: to a file named "Deblock_QED_i.avsi" and imported it and reloaded.

Import("D:\Plugins\Deblock_QED_i.avsi")
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", CPU2="ooooxx", info=3)
AssumeTFF()
Deblock_QED_i(quant1=24, quant2=28) # edge, internal
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
#denoise

Got error on reload


4. So I have imported "Deblock_QED.avs"

Import("D:\Plugins\Deblock_QED_i.avsi")
Import("D:\Plugins\Deblock_QED.avs")
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", CPU2="ooooxx", info=3)
AssumeTFF()
Deblock_QED_i(quant1=24, quant2=28) # edge, internal
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
#denoise

Then reloaded to get error


4. Upon checking http://avisynth.nl/index.php/Deblock_QED, I see this needs DctFilter, DeBlock, MaskTools2
So I have added all the dlls.

Import("D:\Plugins\Deblock_QED_i.avsi")
Import("D:\Plugins\Deblock_QED.avs")
LoadPlugin("D:\Plugins\DctFilter.dll")
LoadPlugin("D:\Plugins\Deblock.dll")
LoadPlugin("D:\Plugins\MaskTools.dll")
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", CPU2="ooooxx", info=3)
AssumeTFF()
Deblock_QED_i(quant1=24, quant2=28) # edge, internal
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
#deinterlace
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
#denoise

Then reloaded to receive error


5. So I have commented line "ColorMatrix(hints=true, threads=0)"
Then reload is success.

6. Now I included "QTGMC(preset="fast", EZDenoise=1.0, DenoiseMC=true)" and reloaded


7. Upon checking I see following dependencies
MaskTools2
MVTools2
nnedi3
RgTools
SMDegrain

So I added each dlls.

Import("D:\Plugins\Deblock_QED_i.avsi")
Import("D:\Plugins\Deblock_QED.avs")
LoadPlugin("D:\Plugins\DctFilter.dll")
LoadPlugin("D:\Plugins\Deblock.dll")
LoadPlugin("D:\Plugins\MaskTools.dll")
LoadPlugin("D:\Plugins\mvtools2.dll")
LoadPlugin("D:\Plugins\nnedi3.dll")
LoadPlugin("D:\Plugins\RgTools.dll")
Import("D:\Plugins\SMDegrain.avs")
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Anjali\sample.d2v", CPU2="ooooxx", info=3)
AssumeTFF()
Deblock_QED_i(quant1=24, quant2=28) # edge, internal
QTGMC(preset="fast", EZDenoise=1.0, DenoiseMC=true)
LoadPlugin("C:\megui\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
#ColorMatrix(hints=true, threads=0)
#deinterlace
crop(4, 76, -8, -72)
Spline36Resize(704,328) # Spline36 (Neutral)
#denoise

On reload, it gives error


Now I feel something is severely wrong

[poisondeathray]

LoadPlugin("D:\Plugins\MaskTools.dll")

That's probably the wrong masktools

The 2.x branch is MaskTools2.dll

Certain plugins can cause error loading of other plugins

Make sure you have the correct version too of each plugin (x86 vs. x64) . Some of them are named the same. For example , nnedi3.dll is the same name for both x86, x64. Also there are different nnedi3.dll versions complied for different CPU architectures. Make sure you have to correct one. (e.g. If you use one that was compiled with AVX2 SIMD support, but your CPU doesn't have it, you will get problems)

No luck

I tried

Tried all masktools2.dll under x64 and x64_xp

[poisondeathray]

This can happen with conflicting autoloading plugins, or avisynth version

What version of avisynth are you using ?

And is your plugins directory "clean" ? if not clean out your plugins directory)

It has lots of other plugins. Its messy

[poisondeathray]

It has lots of other plugins. Its messy

Clean it out . If you want to back them up, move them to a subfolder . All those get loaded up at runtime, so makes it slower too

Then add only the ones that you need back one by one , or use LoadPlugin() (but keep them in subfolders) .

But that's not the default avisynth/plugins folder where things are autoloaded from. Unless you have a custom install or altered the registry

Still same error

[poisondeathray]

Run

avsmeter64 avsinfo -log

This will give you info, and list all the plugins, dates , versions


What are you using to preview the script ?

[poisondeathray]

That folder is for x86 plugins . Most people have separate x64

Also you are loading mvtools2.dll with LoadPlugin, but it's mvtools.dll in the screenshot (I don't see mvtools2.dll) . mvtools.dll is very old too just look at the dates - that's a culprit for some problems too

You need to check all locations where avisynth might be autoloading

x64 means inside Program Files isnt it.

I dont have an AvsSynth folder under Program Files
