Hey guys, I didn't mean to cause trouble in the thread, I was just wondering if I was missing something using Avisynth! Kwag you and fellow members are awsome and I was just trying your scripts to see how good compression you get. Notice the three different sample sizes? I guess I was wondering if I sould be putting something in the () after some of the filters. That is why I also posted my process and versions of software I use. I dont know that is why I post. I guess I should have came right out and asked that

By the way, please dont lock me out. I am just tryin to learn

I dont think I broke any rules LOL

Right now I'm a little confused.You're all talking about 130 Minute Movies fitting on 1 CD,I understand that so far.But how are you able to get a CQ value of around 70???

I wanted to encode the Movie "Spygame",which has 122 Minutes.The maximum CQ Value that I could get was 45.Remember,you are encoding 130 Minute Movies with CQ 70 I'm encoding 122 Minute Movies with CQ 45.

Can someone explain all that to me???

Bchteam · #84 03-03-2003, 07:24 AM

I have to add something.

A couple of days ago I encoded The Movie "The Others".It has 100 Minutes.The CQ Value was around 79.I mean 79 is very good but compared to Kwag's CQ 70 for a 131 Minute Movie,my 79 is nothing.

The Same with "Kiss of the Dragon,which has 94 Minutes.The Maximum CQ was 71,which also very good.But compared to Kwag's CQ 70 for a way longer Movie,my 71 is nothing.

I just can't understand it.

Especially "The Others".It has almost no Action scenes and it is very dark.

Kwag,are you a Wizard???

, but looking at your script above, you are puting the subtitles after all your filters, and that will kill a lot of quality. Change your script to this:

Code:

mpeg2source("G:\HDR\HerrdeRinge.d2v") 
LegalClip() 

GripCrop( source_anamorphic=False, width=528, height=576, overscan=2 ) 
GripSize(resizer="lanczosresize") 
VobSub("G:\HDR\HDRSubs\Tonspur 1\VTS_01_0") 
mergechroma(blur(1.58)) 
mergeluma(blur(0.2))  
FaeryDust() 
FluxSmooth(7,7) 
NoMoSmooth(40,1,6,1,3,false) 
Convolution3D(preset="movieHQ") 
DctFilter(1,1,1,1,1,.5,.5,0) 


GripBorders()    
LegalClip() 
Sampler(length=24)

Hi guys!

Just a quick question;

Where do I find this filter:

<<LoadPlugin("F:\Programme\AviSynth2\dctfilter_YUY 2.dll")>>

Thanks

@Kwag, testing the above script with tOk (only prediction), the encoding time for just one sample is 15min on my P4-1.5Ghz...damn sloooow!
U got the same time on your PC?

Hi VILLA21,

hedix is aware of the problems, and he's addressing them

@Kwag:"....looking at your script above, you are puting the subtitles after all your filters, and that will kill a lot of quality. .."

Wouldn"t that kill also the compressibility of all these filters(mean apply subtitles before filters)?

You will get better quality (higher CQ) because of the better compressibilty if you put the subtitles before filtering

Thanks Jellygoosse for bringing this mergechroma to our attention!

Yeah, I just knew this thread was going to take us somewhere

. These filters really make a huge difference. Anyone encoding at 352x240(28

with all these filters added up, can actually encode with CQ=100 and get a ~120 minute movie on one CD

, and even at CQ=100, sampler size is still below wanted size (on most movies)

-kwag

I still don't understand how the mpg gets to 800meg. When I use the 120min template I get 1.6gig files (2CD). Do I need to drop the max bitrate to 900 so that I get one CD ??? Like with the above "~120 minute movie on one CD

" what are you changing in the template to get it to one CD? CQ? Bitrate? Because when I look at the template it uses CQ60 and max bitrate of 2500 which ofcourse will give you 2 CD's.

If you put the subs before GripBorders() then the subs will appear over the movie, if you put then after GripBorders() they'll appear on the black bar below the movie (except if it's a two-line sub). Some people don't like it when you have a letterboxed movie with only ~360 lines of heigth (or less - I've downloaded a xXx avi that's 256 lines high) and then put two lines of text in big characters over it

, specially when you have those big unused black bars above and below.

And if you move GripBorders() to before the filters, filtering takes more time and the borders get smeared

There's a paliative - you can check the "smooth" box in VOBSUB.

I'm glad my player handles CVD subs

Wow guys, it's so hard to keep up to date with all the latest new filters and settings people find. So glad I stumbled on this thread! Currently trying to encode an SVCD of Chicago onto one CD. I notice that the filters used are for DVD sources. Anyone tried to see if any changes need to be made for noiser sources, like SVCD or DivX? Should we change SpaceDust() to PixieDust()?

P.S. Kwag I really think you ought to put a sticky linked to the main KVCD page with your latest AVS script(s). And possibly links to some threads of interest as well. Just an idea!

.
.
because my source is Satellite, and mostly pretty clean (xcept for when the
source is made crummy (blocks)) I use pixieDust() whenever I can.

As far as any filters being slow.. well, if the quality is better then going
faster, but w/ less quality, I'll stick w/ the slow filter. It's more than worth
the time

he he..

Just using pixieDust() is a quality giver !!
