The movie: "La Pianiste", PAL, 16:9, ~125min

1st attempt:
---AVS Begin---
LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec .dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.DLL")
mpeg2source("E:\Video\Movie\DVD2AV~1.D2V")
BilinearResize(352,216)
AddBorders(0,36,0,36)
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\NoMoSmooth.dll")
NoMoSmooth()
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\Blockbuster.dll")
Blockbuster( method="noise", detail_min=1, detail_max=10, lv=1 )
Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=20 )
AvisynthSubtitler("E:\Video\Movie\Subs\","permsubs .txt")
----AVS End----

Pred.Factor=0.95
Video Encoding time: 3h 30min
File size: 780MB
Comments: Very poor quality,dark, too many blocks

2nd attempt:
---AVS Begin---
LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec .dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.DLL")
mpeg2source("E:\Video\Movie\DVD2AV~1.D2V")
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\UnFilter.dll")
Unfilter(20,20)
BilinearResize(352,216)
AddBorders(0,36,0,36)
LoadPlugin("C:\Program Files\DVD2SVCD\MPEG2Dec\MPEG2DEC2.dll")
TemporalSmoother(2,1)
AvisynthSubtitler("E:\Video\Movie\Subs\","permsubs .txt")
----AVS End----

Pred.Factor=0.97
Video Encoding time: 2h 30min
File Size: 815MB
Comments: Amazing quality! blockness

Conclusion:
Using Unfilter and TemporalSmoother gave me excellent results, fast encoding and increasing the Pred.Factor to 0.97 the final image almost filled the CDR capacity.

PS: I post it again to the right thread, sorry

Hi VILLA21,

Could you try this combination:

FluxSmooth(temporal_threshold=7, spatial_threshold=7)

######## Auto Strength, proportional strength depending on resolution #####
## Remove only one "#" on front of the resolution that matches your encoding.


BB_Resolution = 352*240
#BB_Resolution = 352*480
#BB_Resolution = 528*480
#BB_Resolution = 544*480
#BB_Resolution = 704*480

BB_StrengthConstant = 352 * 240 * 20 # Base strength
StrengthValue = round (BB_StrengthConstant / BB_Resolution)
Blockbuster( method="noise", detail_min=1, detail_max=10, lv=1 ) # Apply noise if complexity is <= 10%.
Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue) # Sharpen only if complexity is >= 20% AND <=90%.

# The last ~10% is left untouched (pass-through), to avoid sharpening highest frequency components ( Peak artifacts, sharpest edge, etc. )
##
################## End Auto Strength ###################


I'm getting excelent results with this combination.

With what predicition factor, Kwag?

Also... some of these tests are being done with various filters before/after the resize and add borders commands. Won't this affect the outcome as well?

(I was under the impression that most/all filters should be run prior to resize at the sacrifice of some encoding speed...)

Kwag,
The links you posted in "What's happening" for KVCD Predictor does not work!

-----Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue) # Sharpen only if complexity is >= 20% AND <=90%.-----

If I don't want that much sharpening in dark scene (I am using KDVD Full-D1, CQ_VBR, Min=1000, Max=4000, CQ=25), do I increase the value of "detail_min" or do I decrease the value of "detail_max"? I tried the combination of "Nomosmooth" and "Blockbuster" in the above-mentioned KDVD settings, the black is too black, the white is too white.

Check again, and if you can't download from SansGrip's site, get the file from the kvcd.net link

3rd Attempt:
---AVS Begin---
LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec .dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.DLL")
mpeg2source("E:\Video\Movie\DVD2AV~1.D2V")
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\FluxSmooth.dll")
FluxSmooth(temporal_threshold=7,spatial_threshold= 7)
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\Blockbuster.dll")
Blockbuster( method="noise", detail_min=1, detail_max=10, lv=1 )
Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=20 )

BilinearResize(352,216)
AddBorders(0,36,0,36)
AvisynthSubtitler("E:\Video\Movie\Subs\","permsubs .txt")
----AVS End----

(Filters before resize)
Pred.Factor=0.97
Video Encoding time: 6h 30m...!!
File Size: 813Mb
Comments: Very good quality though i can"t tell the diference from Unfilter+TemporalSmoother

4th Attempt:
Again Unfilter+TemporalSmoother but before resize at this time.

---AVS Begin---
LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec .dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.DLL")
mpeg2source("E:\Video\Movie\DVD2AV~1.D2V")
LoadPlugin("C:\Program Files\DVD2SVCD\Avisynth\UnFilter.dll")
LoadPlugin("C:\Program Files\DVD2SVCD\MPEG2Dec\MPEG2DEC2.dll")
Unfilter(20,20)
TemporalSmoother(2,1)
BilinearResize(352,216)
AddBorders(0,36,0,36)
AvisynthSubtitler("E:\Video\Movie\Subs\","permsubs .txt")
----AVS End----

Pred.Factor=0.98
Video Encoding time: 3h 30m
File Size: 817Mb...!
Comments: Very good quality

PS: On the weekend i"ll try the latest versions of FluxSmooth+Blockbuster with pred.factor=0.98 or...0.985, as i"ll be away from home for 2 days...
