Avisynth: Latest Script Discussion

kwag · #1 04-01-2003, 03:10 PM

Here's the latest test script. Valid for the next 10 minutes

Code:

LegalClip() 
GripCrop(528, 480, overscan=2,  source_anamorphic=false ) 
GripSize(resizer="BicubicResize") 
mergechroma(blur(1.58)) 
mergeluma(blur(0.05)) 
SpaceDust() 
TemporalSmoother(radius=2, strength=3) 
TemporalCleaner(ythresh=5, cthresh=10) 
STMedianFilter(6,15,4,7,6,15) 
DctFilter(1,1,1,1,1,.5,.5,0) 
GripBorders() 
LegalClip()

I get a smaller filesize by putting SpaceDust() between TemporalSmoother and TemporalCleaner...

Thanks!

You see, I told'ya it was only going to last 10 minutes

It actually lasted ~20

DorvalCS · #6 04-01-2003, 04:19 PM

I see that!!!

That's why I suggested that you post it once a week.... Whatever is the latest script at the time.

Otherwise... you are absolutely right... There is going to be a new one every 10 minutes....

At least we'll only have to look through one thread to find the lastest!

maybe there´s something wrong with my eys.

i compared kwag´s script with this script

Code:

mergechroma(blur(1.58 )) 
mergeluma(blur(0.05 ))
LegalClip()
GripCrop(528, 576, overscan=1, source_anamorphic=false)
GripSize(resizer="BicubicResize")
SpaceDust()
Convolution3D(preset="movieLQ")
GripBorders()
LegalClip()

i got a video with this script , which is a lot less blury and a bit sharper.
i made samples with both script´s at cq 65 and 70.

strange. the more filters, the more blury the video?

kwag, can we see a sample using this script?

Check the last posts here: http://www.kvcd.net/forum/viewtopic.php?t=3366&start=45

My latest test script is this:

Code:

LegalClip() 
GripCrop(528, 480, overscan=2,  source_anamorphic=false ) 
GripSize(resizer="BicubicResize") 
SpaceDust() 
sharpen(1.0) 
mergechroma(blur(1.58)) 
mergeluma(blur(1.0)) 
GripBorders() 
LetterBox(16, 16, 16, 16) 
LegalClip()

Info on the link above.

To be tested:

Code:

---  GripSize Line Here---
SpaceDust() 
sharpen(1.0)
TemporalSmoother(radius=2, strength=2)
TemporalCleaner(ythresh=1, cthresh=15) 
mergechroma(blur(1.58)) 
mergeluma(blur(.7)) 
--- GripBorders Line Here ---

Added TemporalSmoother with very small strength and radius values.
Added TemporalCleaner with very strong treshold ONLY on chroma and minimal value for luma.
This drops file size considerably, while still retaining quality without "smearing" the picture.

i can see no difference in image quality between those two script, but the script WITH temporalcleaner and smoother was 0,1MB bigger than the other i took 90sec longer to encode

PyRoMaNiA · #13 04-02-2003, 02:56 PM

Those TemporalSmoother values dont look too different from the first script you posted...

Sure they do!.
The originals:

Code:

TemporalSmoother(radius=2, strength=3) 
TemporalCleaner(ythresh=5, cthresh=10)

The new ones:

Code:

TemporalSmoother(radius=2, strength=2) 
TemporalCleaner(ythresh=1, cthresh=15)

That makes a huge difference

The image quality is identical, but the file size with the temporals will be smaller. Sure you didn't mix the encodes

There's no way a file size can be larger with the temporal filters

what does this line make source_anamorphic=false ? Havent seen it before...

kwag · #17 04-02-2003, 03:11 PM

I'm not sure if anyone here remembers the original "The Green Mile" samples posted last year. So here's a new sample created with the script above, using MIN=64Kbps, MAX=1,150Kbps and a CQ of 80. Full sampler size was ~12MB, which is the correct size to target the complete 180 minute movie on one CD at 352x240. Here a 30 second clip so you can see how it looks. http://www.kvcd.net/mile-2003.mpg

That's created automatically by MovieStacker, depending on your source.

Kane · #19 04-02-2003, 03:14 PM

i made those sample both with cq 70 to see, if there´s a difference in file size
now i make prediction with ToK for both scripts, let you know, what comes out

kwag · #20 04-02-2003, 03:20 PM

My file size difference using the temporal filters is ~150KB lower per every 30 seconds. Let me know your results
