Avisynth: Motion Adaptive Filtering Now Possible? - Page 22

vhelp · #**421** 06-07-2003, 01:24 PM

Hi all..

Ok, I'm finally bustin in here.. ben quiet for far too long hehe.. So, let me
start w/ an request if I may

@ BP..

Quote:

Picture quality near DVD. Filesize 776MB, Tok file prediction was perfect.
Small problems though, from 2 to 3 feet viewing 23" standard screen, Gibbs

Any chance on see those GIBs you were talking about on page 26 dude ??
A small 2 mb should do it, else maybe Kwag can do it for ya w/ your
script and movie.

I'm asking because I got an NEW monitor and I'm seeing things that I never
rally saw, in my encodes. So, it's an enlightment really. And, an aid or tool
too, cause I can fine-tune even more, certain areas in my encodes.

Basically, my LCD monitor is like a mini HDTV. Like, I've ben playing some
of my DVD's in PDVD, and am noticing things I can never see on a regular
CRT monitor (and TV set)

So, I'd like to use my LCD as a guage (maybe help you all out too) or tool
in fine-tuning encodes and things - pretty anal but a

great idea if we are
serious in our altimate encoding quality !!

Hope you can help.

@ Kwag

after my last post i try to find the prediction in ToK again using:

LoadPlugin("C:\Filters25\MPEG2Dec3.dll")
LoadPlugin("C:\Filters25\undot.dll")
LoadPlugin("C:\Filters25\asharp.dll")
LoadPlugin("C:\Filters25\decomb.dll")
LoadPlugin("C:\Filters25\STMedianFilter.dll")

MaxTreshold=1.50
scd_trigger=15
nf=0

Mpeg2Source("D:\La Luna\Segment2\DVD2AVI_PROJECT_FILE.d2v")
undot()
Limiter()
asharp(2,4)
FieldDeinterlace()
BicubicResize(688,464,0,0.6,0,0,712,480)
STMedianFilter(8,32,0,0)
MergeChroma(blur(MaxTreshold))
MergeChroma(blur(0.2))

ScriptClip("nf=YDifferenceToNext()"+chr(13)+"nf>2. 5?asharp(-(fmin((nf/35),1)),0):\
TemporalSoften(2,7,7,3,2)")
ScriptClip("nf>scd_trigger?asharp(-2,0):asharp(0,0)")
AddBorders(8,8,8,

Limiter()
function fmin(float f1,float f2){return(f1<f2)?f1:f2}

thanks for the hint ... "ToK MotionEstimate".

Hi jorel,

Maybe it's your 29.97fps movie you're trying to encode

Have you tried the script on a 23.976 Force FILM .d2v

Here's a 19 second sample with motion estimation set to "Fast" and CQ set to 62.7 ( target for one CD, predicted with ToK ):

Hey Kwag is that 704 or 528

cause i got that movie to encode,
I know it should fit in 1 cd sence is Letter Box and the hole movie is Dark.

Yes it brakes up Doesn't it Vhelp

vhelp · #**427** 06-07-2003, 02:27 PM

@ Kwag..

Sorry for late reply.

Yes, I D/L'ed both those sample

What I observed...
* http://www.kvcd.net/red-planet-sampl...on-cq62.70.mpg
your GIBS and patchy blocks.

What I liked...
* http://www.kvcd.net/red-planet-sampl...y-cq63.031.mpg
MUCH less gibs, but some patchy blocks*** still.

*** I have some things to talk about on this - short followup
comming.

Both clips looked much good, but the 2nd looked much better

PS: sorry, but my image fallups and your server got my timing wrong w/

@ Kwag..

warning..
Something happend to your clip (below) ..it's mostly garbled w/ artifacts.

vhelp · #**432** 06-07-2003, 03:18 PM

@ Kwag..

clip.. A.OK. Much better !!

Ok, some things to note (or theories)...

* When clip(s) are played under vdub, quality is outstanding. I theorise that
it's either playing these MPEG clips in YV12 color space, OR, 4:2:2 space.

* When clip(s) are played under PDVD, quality is ok.. probably due to
the 4:2:0 space and monitor (weather LCD or CRT, as it doesn't matter in
this case) I do think that it does play w/ better quality once burned to CDR
and played DVD and TV.

Now, I recall reading a discussion on DVD's MPEG color space.. that it's
sampled at YV12 natively or something. I don't recall the exact explanaa,
but to that effect.

Now, give the above, theories, I think that once we re-encode these to
MPEG's, we up obviously changing the color space. Somehow, these soft.
encoders are altering the color space OR, the software players are at fault,
hence vdub's great quality vs. PDVD's poorer or not-so-great

It would be interesting to note how vdub is using color space per say.. and
how come, PDVD does not use this same codec during play. Perhaps, it's
something to do w/ how PDVD utilizes the OVERLAY vs. vdub use of RGB.
Would be nice if you could set PDVD to use RGB and NOT OVERLAY.

Any thoughts ?? anyone ??

@jorel,

I had the same problem with low CQ for any resolution from Tok until
I removed all avisynth versions and their registry links. I re-installed
avisynth v2.52 by itself and Tok started giving me CQ's in the 60 to
70+ range. Of course, picture quality jumped to execellent. Give this
a try

@ black prince!
did you only deinstall and install again or some more like
edit the registry,give me the hints my friend.
i remember in this thread you talking about this problem.

i'm unistall and reinstall again the 252 to see what happen.
some more hints please bp.
thanks in advance!

ovg64 · #**436** 06-07-2003, 11:36 PM

Hey Jo editing the register is a becarefull thing, I suggest you use
a program like Norton Win Doctor if you going to do that Unless
you are a pro, but it does help when you clean the sucker from
programs you dont have anymore.

ok ovg64,

a few months ago i was using norton system works and cleansweep,
now i'm using evidence eliminator.
after unistall, i search trying to find avisynth.dll
in the system and the file isn't found no more.
now i'm installing again and finding a new prediction.
maybe i can get more CQ, if don't i call for
my secret weapon.....

black prince help and you all.

@jorel,

I use ace utilities to clean the registry for links that remain after uninstalling
programs, deleting files, etc. This utility has 5 small programs that do
do a great job cleaning your HD of temp files, recycle bin, registry, etc.
Your can find a trial version (30 days) of ace utilities at download.com. Next, I
compress or defrag the registry using a batch file with the command
"scanreg /fix" written in it. This is a windows 9x/me program that creates
a backup of the registry and then compresses it. This program will restart
you computer. I defrag my HD with Diskeeper 7.0. It's fast and very good.
I also us a free anti-virus program, AVG anti-virus, at grisoft.com that has
automatic updates free and protect your HD in DOS and/or Windows. That
means if a virus won't allow you to enter Windows, it has a DOS program
to remove it.

Both DOS and Windows are automatically updated. My
system runs like the first install after I perform these tune-ups

-bp

BTW, If anyone has some great system-tune programs, let us know.

black prince · #**439** 06-08-2003, 09:18 AM

@Kwag,

Changing Tmpgenc's motion search to fast made a much better improve-
ment in Gibbs and picture quality. I'm doing some more testing for how
well this script acts when the target filesize is one CD (80 minute) and
the movie is 2+ hours long. I also want to see if UnDot() is really making
a difference in picture quality. It's suppose to improve Gibbs if the source
has this problem to begin with. More testing with this script and we can
determine some reasonable limits for which resolutions are recommended
for movie lengths, type of movie (action vs drama, etc). There will be
more tweaks and enhancements with this for sometime to come

@ all..

Hi guys !! I'm back, and I got my IVTC (via new decomb for AVIsynth v2.52) working in my finally installed AVIsynth v2.52 machine hehe

I haven't fully tested it, but I'm going to assume that I will have similar
results w/ my prevous decomb for v2x. It took a full days sillyness to get
where I am today

Anyways..

@ bp..
can you elaborate on what Gibbs actaully look like. I have a feeling I know
what you are talking about, but to be quite honest w/ ya, I missed the boat
when this was started. Can you provide a picture detailing these Gibbs ??
I would really appreciate it, so that I can better refer to scenes w/ Gibbs
more accurately.

Now, if I think I know what you are talking about in Gibbs, and what I have
ben working on this weekend, IS in fact Gibbs, I may or may not have a
working (requires tweaking per Movie) few steps. I ran lots of tests last
night, and finally burned a cdrw and tested it on my 13" tv. And, they seemed
to look ok, however, on my mini HDTV (I mean) LCD screen, I did notice
the quality (less Gibbs) during play via PDVD (color set to "0")

Thanks for your help.
