Testing DVD2SVCD 1.1b1a and Prediction Factor
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. -kwag |
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. |

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... |
