I have notied that too ren, and I'm adding a work around that

But I also see a problem in your script, and that is that you are using fixed values ( 1.58 ) instead of using value returned as the parameter to blur. This causes a sharp turn on/turn off of the filter between boundaries, and will make sort of "flashing" visuals every time a filter is turned on and turned off

With this new adaptive script I noticed that the colors were washed out... It is especially noticeable with the black

Is it just me?

install avisynth251 with ffvfw option!!!

You're right! There's flickering which is especially noticeable with the credits. This is !muy no bueno!

Hey, no sweat

, it's been only a couple of days and we already can encode at 704x480 with a >~30% better quality than two days ago

So it's a matter of fine tunning this stuff, and we'll be rocking

I see you guys are talking allready about encoding more at 704x480 but with my Athlon xp 1700 i dont think ill be doing any 704 yet even with the 30% speed improvement in avs2.51.

Maybe we should get some Donations and buy Muaddib that Mothemboard that way we can speed up things a little.

Yeah, let's take donations and when we get enough, I'll buy him a new 3 Gigahertz P4, but I'll keep it and send him my P4 @1.6Ghz

My dream mashine a full power 3 Gig P4,
Three years from now when i get it it won't
be the dream mashine anymore.

MUCH MORE THEN SURPRISED!!

I need to install AVS2.5 to try that!
(well I need to install everything again... I did a fresh install of WinXP)

BTW... my system is now stable (i hope) and it's flying smooth!

I just bought a new machine and it's really "near" of my dream system.
Here is my rig:
ABIT IC7 - Pentium IV 2.53GHz - 512MB Dual DDR 400 Kingston
MSI GeForce4 Ti4200 AGP 8x - 2x 80GB UDMA133 (8MB buffer) Raid 0

Oh man... this baby is FAST!

Nice Rig Muad, wouldn't I like to call Michall Dell and tell him to send me one 4 Christmas.

@kwag,

I rewrote the script I posted earlier:

Code:

Loadplugin("C:\encoding\filters25\MPEG2Dec3.dll")
Loadplugin("C:\encoding\filters25\Deen.dll")
Mpeg2Source("D:source.d2v")
Deen("m2d",1,10,12)
BicubicResize(512, 462, 1/3, 1/3, 5, 0, 710, 480)
val=0
amnt=0
FrameEvaluate("val=YDifferenceFromPrevious()")
ScriptClip("amnt=((val/10)>1.58) ? 1.58 : val/10. blur(0).Subtitle(string(amnt), y=30)")
ScriptClip("Subtitle(string(val))")
ScriptClip("val>=10 && val<20 ? blur(1.58).blur((val-10)/10) : blur(0)")
ScriptClip("val>=20 && val<35 ? blur(1.58).blur(1.58) : blur(0)")
blur(amnt).mergeluma(blur(0.2))
AddBorders(8, 9, 8, 9)
Limiter()

It transitions a lot better (not as much flickering). YDifferenceFromPrevious values above 35 seemed to usually be scene changes so i made 35 the cutoff point

Hi ren,

The trick is to keep a variable assigned from the last frame, and compare to the current frame. Then establish a trigger threshold. So when there is a scene change, there is an abrupt change in val, and we don't apply filters at that point!
Right now I'm looking with Vdub at the value that is assigned to val on every scene change. It's usually above 3. So I'm modifying the script to consider that if (last frame to current frame diff is > 1) "abrupt change!", don't apply filters, because usually a frame to frame change increases or decreases at around .2 to .3, but not any higher

Hi all!

after watching the first movie on my TV encoded with the new script, I have to say that I'm still impressed... I haven't noticed any bad colors at all... black is completely black, and colors actually look more natural than before in my eyes...

however I did notice the flashing you guys were talking about. It's not very obvious, however, I'd like to get rid of it...
kwags idea sounds great, as usual, so I'm just leaning back, waiting for new script-food!

jorel · #**174** 05-31-2003, 05:45 AM

i had big problems,
was the decompressor.

using this script and avisynth251 my result was washed...horrible.

solving the problem:
install avisynth251 with ffvfw option!!!

i got the big sample that Kwag give with 11.8mb,
the image is incredible!

!

Jellygoose · #**175** 05-31-2003, 05:55 AM

I can't even remember installing a YV12 decompressor... however, my picture quality is amazing with this script...

sorry jorel, I don't know what's going on ...

Are you talking about the latest optimal script from Kwag???

seems that only i had this problem....
but no more, see what i did:

"Reinstalled only AviSynth 2.51 WITH ffvfw option!"

thanks DorvalCS for this big hint.

edited,
big quality now.

way higher than 3 (like ~35-200). I wonder why the numbers you're talking about are so low

Are those numbers the YDifferenceFromPrevious divided by a constant?

btw- i'm using 528x480 in case it's because of using different resolutions

thnx,
ren

@ friendalunit and Kwag

excuse me this "pause" friends:

now my system is working with a help from DorvalCS.

the error was that i wasn't install the ffvfw option.

now everything is "shine" with avisynth251..
i see grat results in samples with great quality.
i never see quality like that....and faster

go ahead friends, you're the best, i'm impressed.
thank you.
