Lowered the sharpen just a tad, and I was able to get rid of temporal filters completely.
Has anyone noticed that using this combination of filters, there's hardly any visible artifacts and/or blocks on dark scenes

It looks more like noise, which gives a more natural feel.
Look at this 10 second KVCDx3 sample, encoded with the above script using a CQ of 60

, which is the way this 117 minute full screen movie looks on one CD. It's from the movie "City by the sea": http://www.kvcd.net/city-by-the-sea.mpg

what was the min/max you used for this? my encodes seem to never look as good as yours.

MIN=300, MAX=2,500

Kwag, which version of Avisynth do you use? When I tried your script mentioned in the beginnning of this topic, the DCT- and STMedianfilter require avisynth 2.50. But the sansgrip resize/crop and dustv5 dll's dont't work with avisynth 2.50.

What's the solution?

Kane · #44 04-03-2003, 07:17 AM

use avisynth 2.08
all those fitlers works well with this version

Somebody important on this site please contact the Dust filter guy. I really like the speed of the new AviSynth 2.51, it is a huge difference on a Pentium 4, and would still like to use the dust filters. I would even donate by PayPal to get his butt moving. So for now I am stuck with Convolution3d. Convolution3d really works wonders on those grainy DVDs though. Since I do not have an HDTV, I really do not notice the blurring you guys talk about with Convolution3d.

Maybe a silly question, but what is " blur luma threshold " and " blur chroma threshold " ?

I found the line when I was reading TemporalCleaner, this part

ythresh (default value = 5) : blur luma threshold (don't go above 8 otherwise you'll have
some ghosting).

cthresh (default value = 10) : blur chroma threshold (you can safely go a little above 8 as
if luma is above threshold -> chroma is automatically kept (no blur)).

DCTFilter only works with 2.5 ¿?

yes it does work with 2,08, although the readme says: avisynth 2.5

@ kwag

this threat is going to explode in a couple of days, if we all continue posting so much.

what about threat called: script discussion
and this threat "latest script" just contains a few script, which we think are the best at the moment?

That was the main idea of this topic, but I can see that it has falled into avisynth questions, etc., which should really be posted on the AviSynth forum

I'll create a new "Read Only" thread that I can update with the current test script and suggestions.

Kane · #50 04-03-2003, 10:29 AM

it´s very difficult to draw a line between script and avisynth
a new script will of course cause questions: (why this, why that?)
the "read only" threat is a good idea, just pure information

kwag · #51 04-03-2003, 10:34 AM

I just created a "Sticky" post

Hey Kwag,
It seems these new scripts are trying to find a peaceful medium between speed and quality.

What do you consider the best filters for turtles like me who don't mind waiting forever for their encodes??

You could play with C3D or other temporal filters, and use very conservative low values

Code:

GripSize(resizer="BicubicResize")

@kwag, how come you're not using bilinear resize anymore? (sorry if I missed that discussion somewhere

)

Jellygoose · #56 04-03-2003, 01:45 PM

hi kwag...

Ok, I like the quality you get with this new script (no more ghosting and weird artifacts with movement), and I totally love the speed.
however the filesize is not just a little above the old script...

For me filesize went up by 1.2MB for 2 minutes. that's a lot more than I can "afford" right now

.
when I increase the luma blur value, picture looks like it's smearing again.

any ideas about what to do?

that's a good one. I'd like to know too...

The picture is slightly sharper with Bicubic

Hi Jellygoose,

Even after you lower the CQ to match the file size of the old scripts, the picture still looks better. Try it

. And don't go beyond 1.0 on luma. It smears the picture. I'm using 0.7.

I don't mind waiting forever either if it means better quality!

Would Convolution3D(preset="movieHQ") be conservative enough? And if so, where would you suggest it should go? After SpaceDust()?

I also noticed you're not using DCTFilter anymore...is it still needed
