Hi J-Wo,
Try mergechroma+mergeluma+spacedust+C3D+TemporalCleane r, but use Convolution3D(preset="movieLQ") :wink: Something like this: Code:
Mpeg2Source("Your_Movie.d2v") -kwag |

try STMedianFilter(8,15,4,7,8,15) faster and a little smaller in size... and quite a few people over at Doom9 go back and forth between STMedian and C3d... http://www.trbarry.com/STMedianFilter.zip |
Hi KingTut,
Check this thread: http://www.kvcd.net/forum/viewtopic....er=asc&start=0 I'm not sure if STMedianFilter can do better than the last script I posted there :roll: Also, it's only for AviSynth 2.5 :!: -kwag |
Kwag,
Yeah I've read that thread... it's comparing a Spatio-Temporal Smoother (C3D) to a Spatial Smoother (Smoother HiQ) but this is a Little faster than C3D and A little smaller... Need someone with HDTV to confirm the quality... both of these filters are Spatio-Temporal Smoothers (C3D & STMedian) If you download the ZIP file you will see an Avisynth 2.0 version as well as an Avisynth 2.5 http://www.trbarry.com/STMedianFilter.zip use these settings... STMedianFilter(8,15,4,7,8,15) |
Re-testing right now with STMedianFilter ... 8)

Once again, C3D wins ( by a very small amount, but it does )
http://www.digitalfaq.com/archives/i.../2003/03/3.png Look at the vertical line (plastic division) on the TV. On the top picture, you can't see the division on the top of the TV set. On the bottom, it's still visible :!: The file size is indeed smaller with STMedianFilter(8,15,4,7,8,15), ~200KB, because it's removind high frequency components from the material. This was the script used for the above sample: Code:
LegalClip() -kwag |
Kwag,
so it seems that... STMedianFilter(8,15,4,7,8,15) is equal to Convolution3D(preset="movieLQ") which blurs the grill on the T.V. :cry: so could you lower the settings so STMedianFilter could be equal to Convolution3D(preset="movieHQ") :?: maybe something like... STMedianFilter(4,15,4,7,4,15) since according the the readme the two settings I changed affect "Large values may cause loss of fine line detail and disappearing vertical fine lines." |

Hi kwag!
don't you think this is really weird?? why should such a heavy filtering and smoothing Code:
SpaceDust() |
Hi kwag!
could you do another comparison for me please? take my script from here: http://www.kvcd.net/forum/viewtopic.php?t=3410&start=15 (at the very bottom) and compare that one with your script : Code:
SpaceDust() [/quote] |
Well, after doing several encodes, I was very sad with the results :roll:
Both filters TemporalSmoother(radius=2, strength=3) and TemporalCleaner(ythresh=5, cthresh=10) really mess up the image on movement :!: You can see "streaks" and "ghosts" across moving images. This doesn't show on static images. So I have been working on something, and I think that I have something really nice :). Look at this script: Code:
LegalClip() Give it a try :!: Here's a sample encoded with the old script: http://www.kvcd.net/sam1.mpg Now look at the same sample encoded with the script above: http://www.kvcd.net/sam2.mpg Look carefully when De Niro starts to go up the stairs. Notice how the image gets messed up with the smoothers. Compare that to sam2.mpg, where there's no "streaking" at all on image movement. Edit: Forgot to mention that the encode speed with this script was 3:37 agains ~5 minutes with the old script :mrgreen: Note: You may lower the value of mergeluma to 1.0. This will increase the sharpness, with a slight increase of file size. But it's worth it :mrgreen: -kwag |
Here's a 20 second sample with the above script ( only changed mergeluma to 1.0 ) using CQ=70 for fitting this movie on one CD.
http://www.kvcd.net/test-s1m0ne.mpg Note: Wanted file size for sample was 11,944MB, and I got 12,712. So CQ will be a tad lower, but shouldn't make any visual difference from the above sample :wink: -kwag |

btw: kwag, which cpu do you use in your computer? my encoding-duration is nearly twice as big as yours |

Hi kwag!
8O This approach to get rid of the ghosting and ugly artifacts is brilliant :!: however, have you tried the method with sharpen(1.0) and the high mergeluma and mergechroma settings WITHOUT dropping the other smoothers, but just decrease their values just a little? SpaceDust() is a spatial smoother, I think, and not a too light one. why not add another Temporal Smoother before that. I LOVED your script, it did indeed look far more natural! it remembered me a lot of great DivX encodes, with no more artifacts around objects! fantastic! :lol: I experimented with this script, and I copied your brilliant idea. This actually comes very close to the old compression, but lets the picture look far more natural as I think. The ghosting was a lot less visible I think... Please see if you can confirm this. Try this script. and as you said, don't panic! :wink: Code:
LoadPlugin("E:\MPEG-Tools\FitCD\MPEG2DEC.dll") |
Hi Jellygoose,
I guess you missed this thread :D: http://www.kvcd.net/forum/viewtopic.php?t=3463 -kwag |
Gosh kwag, you're always faster! :lol:
ROFL To write this has taken so long... :wink: I'll try that new script with the new settings! |
