i am now testing your filter with some very clean but fast scene (from quantum of solace) from my first test seems that shotsharpen() , without preset will rise the bitrate by a little (2%( i will test light and film too, and then with very noise source (first alien movie) BHH

WriteFile(..., append=false) overwrites any existing file, but data is written for each rendered frame. Normally, that is what one wants. With ScriptClip("""WriteFile(..., append=false)"""), a separate instance of WriteFile is created for every frame, each one overwriting the data written by previous one. Normally, that would be undesirable, but in your case, you only want to see the final value, so it works. |

You can rise blur up to 24 (more blurring) and/or lower mouv to 30 (more motion detected) to rise overall compressability. Quote:
For Startrek1, beside the awful colors, I had good results with a MCTemporalDenoise(settings="low") Did Edit: the params for softsharpen() without presets are given in a previous post: http://forum.doom9.org/showthread.ph...91#post1323291 For "film" it is blur=15 sharp=18 derin=4 move=41 denois=5 denoisT=8 For "light it is blur=12 sharp=13 derin=3 move=35 denois=2 denoisT=5 We exchanged a lot Leon and I to tune the preset light aimed for a xvid encode with Vaq, sharp resize and sharp matrix.

Ah, the joys of Avisynth's run-time filters...
They can often lead to surprising results, which is why I developed GRunT. But here I think it is reasonable that WriteFile(append=false) still writes data for all frames, overwriting the original file contents. Otherwise there is no way to do that, and that is what is normally wanted. You have discovered a useful 'trick' to get the effect you want, which is much less commonly needed. |

Version 6.8.
Faster debanding Less constraint on the resolution: (before) version 6.7 needs mod16, (now) version 6.8 needs mod4 Optimised sharpening process Some other corrections : better code (see Gavino) for instance. Last edited by leon1789; 17th September 2009 at 08:58. |

version 6.9
-- Fixed a bug when "Sharp=0" in version 6.8 -- Experimental antialiasing ("AA" parameter), not perfect at all, but very fast : Source http://img17.imageshack.us/i/sourcep.png/ Source.SoftSharpen(preset="anim",net=40) http://img17.imageshack.us/i/softsharpen1.png/ Source.SoftSharpen(preset="anim",net=40,AA=12) http://img21.imageshack.us/i/softsharpen2.png/ Antialiasing (AA=12 for instance) can be activated only when Sharpening is active (Sharp>0).

Lol,
Thanks to Leon for his patience. I imagine it is kind of hard to tune a script for MT and not having a multicore Did

The blur effect is kinda ugly in my opinion, because it's not uniform across large areas. Also, it looks a little bit like what you'd get if you Blur()'d and then sharpened. Wouldn't it be better to just Blur() instead of use a denoiser?
Although in my opinion, you don't want to blur at all. You just want to protect the areas with motion blur from being sharpened, because that doesn't do anything good, and at times it can be very ugly. |

No blur?, no problem use blur=0 If you re-read the first post (or my post n°5), you will see that sharpening is done only on static areas, blur on motion area and denoising (temporal) on noisy blocks detected. Blur is handy for increasing compressability (usually motion is not seen at normal speed). You can use show=true to get a visual representation of these 3 effects: green for sharp, red for denoise and blue for blur; explanations in post 4. Did

That's it BigDid

Blurring and denoising are two different process: the first can't replace the second. |

Well, I guess this is no longer relevant since you don't do things this way anymore. |

Can't run SoftSharpen
Not sure what I'm doing wrong. I have a YUY2 capture, and I am trying to apply this script as follows:
Code:
Import("c:\Program Files\avisynth 2.5\plugins\SoftSharpen.avsi") AVISource("gd1991-04_27_s1.avi") converttoYV12(interlaced=true) SoftSharpen(blur=0) Avisynth read error: CAVIStreamSynth: System exception - Integer Divide by Zero at 0x10140d87 I put all the listed filters in my avisynth 2.58 plugins directory, and believe I have the most current versions. They are as follows: asharp.dll - asharp 0.95 Deen.dll - deen_25_dll_20050705 DGDecode.dll - 1.5.5 gradfun2db.dll - gradfun2db_25_dll_20060315 MSharpen.dll - msharpen_25_dll_20030408 mt_masktools-25.dll - MaskTools2 2.0a36 mvtools2.dll - mvtools-v2.5.5 RemoveGrain.dll - 1.0b (tried 0.9 also same result) |

I tested your SS script (in the past there has been errors for value=0) OK. I believe you may have prerequisite versions different from what is used for SS, maybe mvtools2 (I use the 2.4.7.0 version). Recommended dll pack can be downloaded here: http://www.unite-video.com/phpbb/download.php?id=2225 Did Edit: never tried it on interlaced input though...
