help avisynth script for cartoon

[david.dgc]

Hi everyone,

Can you help me to improve this script ?
I think that there is some noise left and maybe a halo problem on the edges ?
Another thing, the resize method, changes the resolution of the video from 1500x1080 to 1440x1080.
Thanks !

I just use Handbrake for this type of stuff, I won't be of much help. That's an option if you need it. HB is so straight forward and easy, avisynth scripts scare me lol

[david.dgc]

Anybody ?
Thanks

[jagabo]

Is that sample the source or the result of your script? I played around with it the other day and went with less noise, sharper, and cropped away the black borders.

It’s a sample from my Blu-ray Disc !

Can you please share your script ?

The script was something like this:

function UnSharpMask(clip v, float radius, float strength)
{
  blurry = v.BinomialBlur(VarY=radius, VarC=radius, Y=3, U=3, V=3) # or GaussianBlur
  edges = Subtract(v, blurry).ColorYUV(off_y=2).ColorYUV(cont_y=(int(strength*radius*256.0)-256.0))
  Overlay(v, edges.ColorYUV(off_y=-128), mode="Add")
  Overlay(last, edges.Invert().ColorYUV(off_y=-128), mode="Subtract")
  ColorYUV(off_u=-1, off_v=-1) #overlay is causing U and V to increase by 1
}

UnSharpMask(1.5, 0.7)
SMDegrain(thsad=1000, tr=3, PreFilter=4)

Prefetch(8) # for multithreading in AviSynth+

But that causes many of the light snowflakes to disappear.

I've been playing around with reducing the temporal noise reduction to retain more of the snowflakes:

function UnSharpMask(clip v, float radius, float strength)
{
  blurry = v.BinomialBlur(VarY=radius, VarC=radius, Y=3, U=3, V=3) # or GaussianBlur
  edges = Subtract(v, blurry).ColorYUV(off_y=2).ColorYUV(cont_y=(int(strength*radius*256.0)-256.0))

Less noise reduction (you can play around with thsad in SMDegrain for more or less) but more snowflakes.

How can i open this script ? I don't know how to "call" the first part :function UnSharpMask(, etc.

I tried to create the script but the "FineDehalo" doesn't load. I have the message "there is no function called finedehalo :

When I originally made that post I accidentally omitted the line that calls UnSharpMask() in the first script. I later edited the post and put it back in. It looks like you got the script before I updated the post.

FineDehalo() can be found here: http://avisynth.nl/index.php/FineDehalo

Put the AVSI file in AviSynth's plugins folder.

I added the SMDegrain.avsi but still this error ?

Try this version of smdegain. It's the one I'm currently using.

[jagabo]

AviSynth+ and many filters have been in a lot of flux the last year or so. That version of SMDegrain requires a newer version of AviSynth+ than the one you have. You'll have to update AviSynth+ or find an older version of SMDegrain that works. I have an older version that might work for you...

It's telling you what's wrong: you need KNLMeansCL.

Or try setting PreFilter to a lower value.

I think is ok with SMDegrain, it tells me now that "no function named unsharpmask". I can't find this filter on avisynth.nl ?
It's wharpsharp.dll ? i loaded it but still the error

I included the custom UnSharpMask() I use in post #7 of this thread. You can copy/paste it into your script. UnSharpMask() uses BinomialBlur() which comes with the VariableBlur package:

I don't know what's causing that. I don't see anything unusual about line 6, LoadPlugin("...depan.dll"). Maybe the prior Import of TemporalDegrain is causing the problem? Since the script isn't calling TemporalDegrain() try removing that line and see what happens.

I would try this comment out (put a # at the start of the line) the two calls to SMDegrain() and UnSharpMask(). (AviSynth will then ignore those lines.) See if the script loads. If it does, re-enable the calls one by one until you find where it breaks.

See post 7, you didn't copy jagabo's inline function into the script

All OK now.
As I said on the post #8, i didn't know that the function for unsharpmask has to be included on the script.
I will try to encode the segment and upload it.
