Avisynth: Info about Kwag and Vmesquita Scripts?

[zagor]

I would want to know two things

The first is:
What is the difference between the following line

STMedianFilter(3, 3, 1, 1 )

in the kwag script's for kdvd

and the line

STMedianFilter(8, 32, 0, 0 )

in the vmesquita guide's v.2.0

the seconth is:

why in the script of vmesquita there is
line:

converttoyuy2()

while in that one of kwag not?

Thanks

Vmesquita maybe got still the old MA in his Guides??

Cause STMedianFilter(3, 3, 1, 1 ) is the newer better working setting of the newer MA release, means the spatial thresholds are set the way that more noise will be shot.

According to ConverttoYUY2() is just a "in safe" command cause VMesquita builded his guides for CCE usage. And CCE internally processes in YUY2 to mpegYV12, so there are some users which do report issues if that line at the end is not set, ... thats all.

ok, thank you
incredibile.

I want to know the advantages of this script:

Quote:

Mpeg2Source("d:\2\corvo3.d2v")
Crop(8,0,704,576)
FluxSmooth()
TemporalCleaner(5,10)
Undot()
DCTFilter(1,1,1,1,1,1,0.5,0)
LetterBox(16,16,16,16)
converttoyuy2()

respect of this other:

Quote:

Mpeg2Source("d:\2\corvo3.d2v")
Crop(8,0,704,576)
LetterBox(16,16,16,16)
converttoyuy2()

i have the same one filesize when i encode in cce.
Thanks

You can't have the same filesize except if you encode in constant bitrate.

[zagor]

then, i have make some test, yesterday, and i got the following results:

with your script the filesize was ~ 9.526 kb
with the other was ~ 9.566 kb

now _I do not remenber exactly the values, roughly are those.

I have only confronted the two video to the PC(notebook), must try to the tv.
it seems that there is no difference.

you tell me which tests I must make in order to understand the difference.
thanks

That is normal to not have a great visual difference : all the scripts here, particulary the ones given as "optimal" ones, are designed to reduce the file size _without_ having a too big impact on the visual quality. The ideal script does nothing at all "visually" on the picture.

But I will encode some samples myself with the 2 scripts above and I will tell you the results.
Which encoder did you use ?
Can you tell me also the min/max video birate you add during your tests ?

[zagor]

Now, i am at job.
but, I remember that i have used:

brate_min=300
brate_max=5000
Q=40
movie is fullscreen, 16:9

naturally I have encoded with CCE v.2.66

Okay, I will use the same things so.

[zagor]

hello phil.
I have made others tests in order to verify the results that I had got.
But strangely I have got results various,
probably the other day the encoder did not work correctly. Effectively it is like you have said.
the script with the filters allows to reduce the filesize, even if for against it increases the times of elaboration.

what u mean info

[incredible]

Sorry my friend, but ...

If you see that post is from March 20th ...

Do you intend bumping up all unanswered posts?

You got 10 postst in your count and you already got some straight answers from Moderators, dont take it personally and be a little wise in your deeds in here, thats all.

PS: Is it that difficult to write at least a full understandable sentence like.
"What do you mean, gimme some info" ???
So please keep the advice of Boulder in mind and write understandable.
Even if my native language is not english I do at least want others to understand me.

Many thanks
