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 :!:

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! :wink:

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

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. :roll:

It's just a matter of time, and a matter of muaddib getting his motheboard fixed :!: His machine went bad (again!) last week, and he told me he would be unavailable for some days until he gets his system fixed. I'm sure he will be surprised when he logs back on :mrgreen:

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

@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

kwag	05-31-2003 12:10 AM

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... :o
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! :wink:

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! :!: ! :wink: :wink: :wink:

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.

big quality now.

8O 8O 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,

@ friendalunit and Kwag

excuse me this "pause" friends:

now my system is working with a help from DorvalCS. :wink:
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 :!:
:o

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

It's because of the line "ScriptClip("val=YDifferenceFromPrevious()/14.55" :) I'm testing on 704x480 resolution.
I'm getting a difference of ~3.x from previous scene to next scene on a scene change.

I think I may be missing something.
How can I do to include this conditional filter into my script.
Should I download a new .dll?
or just using the provided optimal script will do?

Many thanks.

What kind of changes may i ask :?:
another :?: what happen if i put the line
MergeLuma(blur(0.2)) in front of the bilinear adaptive script line?
will it work like it suppose to?

I would add mergeluma(blur(0.1) as a static filter, and leave higher values as dynamic with the adaptive function.
Go ahead and add it :!, it will then make the MIN sustained value of 0.2 instead of close to 0 as it is now.
So the script should read something like this:

Code:

MaxTreshold=1.58 



UnFilter(50, 50) 

BicubicResize( Your_Resize_Values_Here ) 

STMedianFilter(8, 32, 0, 0 ) 

TemporalSoften(2,7,7,3,2) # Experimental! 

mergechroma(blur(1.50)) # Static filtering

mergeluma(blur(0.1)) # Static filtering

## Dynamic linear adaptive filtering ## 

ScriptClip("val=YDifferenceFromPrevious()/14.55" + "val > MaxTreshold ? MergeLuma(blur(MaxTreshold)) : MergeLuma(blur( val ))") 

## 

#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker! 

#AddBorders( Your_Values_Here ) # Depends on situation. Use MovieStacker! 

Limiter()

Now the file size will be even smaller that before :D

Edit: The changes to come are to detect scene changes, and avoid abrupt changes in blur, which cause slight "blinks" on some sporadic frames.

Is there a way of getting rid of Gibbs in this excellent new script? Like the Dust filters... I know the Dust filters don't work in AviSynth 2.5* but are there any similar filters that work in the same way as FaeryDust for example?

ovg64

05-31-2003 05:38 PM

The only other noise filter i know other than STM for 2.51 is Deen witch is works like Convolution 3D and give you even a smaller file size when use it with STMedian. :)

Ex. deen("a3d",1,10,12)

yet another faster version?

Thanks Jorel :wink:

05-31-2003 06:06 PM

of course my friend,
see some ...

Optimizations:
* Added MMX RGB24->YUY2 conversion.
* Minor changes to existing RGB32 -> YUY2 MMX.
* Minor speedup to ISSE limiter.
* Added SoftWire dynamic compiled horizontal resizer.
Approximately 10-15% faster - maybe even more on P4.

:)

Hi kwag,

The scene change detection was perfect in your 'city by the sea' sample :D
Do you still have the script that will add those subtitles? I'd like to do some testing too and those subs would be very helpful- i tested a script with evaluation of next frame yesterday and the encoding time doubled! 8O I'm going to try this one now 8)

Thanks!
