Did you check carefully on horizontal pannings on dark areas :?:

-kwag

What does "Pannings" mean???

Well, I'm not Kwag (obviously :) ), but horizontal "pannings" would be when the camera moves(pans) from left to right or vice versa. Like if there were 10 people standing in a line-up and it started at the first person on the far left and moved across until it reached the last person on the far right. :wink:

-d&c

panning is when the camera man is shooting footage left or right.. like in
a circle, but could also be parrellel, as when you are jogging w/ a friend..
side by side, you are said to be in a "parrellel" position. Now, take a cam
and hold it steady, while you jog, and point cam toward houses that you
pass..

. . that's basically PANNING.
-vhelp

When the camera moves "pans" horizontally across some scene. Take a carefull look on a dark scene. That's how I determined that the temporal filters were screwing up the image. It looks like part of the image is lagging behind the real image. It's also called a "ghosting" effect. With the current filters, there's no ghosting at all. At least I can't see any on my HDTV. But as soon as I start increasing the temporal values, and even adding spacedust, the image looses details, and the effect starts to show. I haven't tried DCTFilter with this filter combination :!:

-kwag

Guess i'm a slow typer :lol:

Ok, now i got it.

I didn't notice any ghosting effect.But I try to find out a dark area scene with panning,make a sample and upload it, so you can make your own opinion.

Or just create your own sample with DCTFilter and make a decision about it.

I'm glad to know that "other"'s out there are realizing that Temporals
and Smoothers are messing up final encodes, hence the various artifacts
you all are describing.

I'm waiting for that BEST script (filter) that works wonders for encoding.
But, until then, I'll continue working on mine, and trying others' here.

As for "dark scenes" so far, i haven't noticed any artifacts when using
Kwag latest Notch matrix - I like it. Anyways.. I'm just following
along. I hope I have some things to contribute here. 8)

-vhelp

WOW, Kwag!!

Kudos on that latest script! Simple, and effective! I like!!

Boy, I'm glad this thread got started :D

I didn't note the difference in encoding time (if any), but last night when I was doing file-prediction, the filesize difference between using and not-using DctFilter(1,1,1,1,1,1,.5,0) was pretty miniscule (as expected). Like I said, I don't recall if there was much of a speed decrease from using it (probably not), but I doubt it'd be that valuable of an addition to anyone's script who isn't desperately in need of more space (like me! :wink: ). I would think any increase in encoding time would probably outweigh the minor compression benefits for most users (those encoding @23.976fps).

My filesize WITHOUT DctFilter was 8.51MB. Filesize WITH DctFilter was 8.45MB.

-d&c

Of course, I suppose one good use for DctFilter (if it is found that it does not have much impact on encoding-time and also doesn't adversely effect quality), could be to add it to your script as a "safety" mechanism of sorts after finding your target CQ, to help ensure that you won't go over your target m1v filesize. But that's a couple "ifs" there. And I've rarely gone over target filesize anyways when sticking to the .98 factor (if ever!)...if anything, I'm usually well under target size and then re-encode my audio to a higher quality. Nevermind me guys...just babblin' to myself over here! Guess I'm putting off my "testing" agony as long as possible! :lol:

Which also has the side effect of functioning as a filter :wink:
That's why the "Notch" name is in there :cool:

New Sample
 

You guys want to see how "Death to Smoochy" looks like on one CD with the current script :?:
Here's a 10 second sample :mrgreen:
http://www.kvcd.net/smoochy.mpg using CQ=51 :mrgreen:

-kwag

8O 8O 8O 8O 8O

ehhh, what´s the play-time of the whole movie?

Kwag..

samples continue looking good http://www.digitalfaq.com/archives/error.gif http://www.digitalfaq.com/archives/error.gif

It amazes me how some time ago, peoples were on the bandwagon about
your templates (be it matrix or GOP's) and I ask myself, "how they are
missing all this great beneits, technique and yes, quality!!"
If they only knew what they were 8O REALLY 8O missing he he..

I only hope that I can ADD to this knowlege-base w/ some more apps, in
addition to picSwitch which works great for me in analizing the images
prior to final encoding. Well, I have something else in mind, but between
juggling multiple apps, new ideas (that keep flooding my brain) and the
work that I bring in to finish up on at home, and surfing and much more
fun stuff, we'll see, he he..

Keep up the good work guys.
-vhelp

110 minutes :mrgreen:

i think i´m too tired and my eyes refuse to work.
i thought i read this movies lasts 110min.http://www.digitalfaq.com/archives/error.gif

HELL, IT DOES 8O


i think this script will survive more than 20 minutes , right? :wink:

I think it will survive MUCH more than that :)
I think I'll just edit the posted script, and add a space for users to add an "optional" filter like 3CD, STM, DCT, etc., ONLY if it's needed ;)

-kwag

sorry but........
 

I hate to be a complete idiot! :)

But i cannot seem to find unfilter anywheres to download...

tks

-kwag

gee
 

Thanks again Kwag!!!!!!!!!!!!!!

:)
tks

Kwag, on the latest script, I'm curious...

Why BicubicResize?? Wouldn't LanczosResize bring out more detail?

Yes, and also a lot more artifacts :o

-kwag

FYI:
When downloading unfilter be sure to pick the old unfilter.dll as the newer one supports avisynth 2.5 only.

-Yoda

Hi Kwag,

I really suggest to add the DCTFilter.I will upload some samples with some dark scenes and then you can judge it.

With DCTFilter you can raise the CQ up to 4 and in my eyes there's no Change of quality.

I tried DCTFilter yesterday, but it bombed on me on AviSynth 2.51. I'll try to figure out the problem later today, and make some HDTV and/or Vdub screenshot comparisons :wink:

-kwag

kwag,
In general, is everyone using Avisynth 2.51?

-Yoda

Most people are still using 2.0x.
I just started doing some tests with 2.51. It's (barely) faster that 2.08, at least on my machine ( Pentium 4 @1.6Ghz).

-kwag

I have to say...using the latest script with the KVCD-CQ-352x480-_NTSCFilm_-PLUS.mcf (in MPEG2 format)
template, on "Band of Brothers" CD3 part6 looks VERY good to me!

With test strips (CQ=59) viewed on our 37" Mitsubishi TV (non-HDTV)
using an Apex 1100w (1meg) these appear to be my best encodes (at that rez) to date.
(I`d like to use the X3 MPEG2 template...but my Apex doesn`t like it,
as demonstrated with Kwag`s test downloads and a couple of my own)

Sript used:
Mpeg2Source("H:\DvD Rips\Band of Brothers\Band of Brothers CD3\BOB CD3-part-2\BoB-cd3-part2.d2v")
GripCrop( width= 352, height=480, overscan=0 )
GripSize(resizer="BicubicResize")
unfilter(50,50)
temporalsmoother(1,2)
mergechroma(blur(1.58))
mergeluma(blur(0.4))
GripBorders()

I`m using Avisynth 2.08, about 3.5hrs to encode using P4 1.7ghz.
For this...I`m trying TMPGEnc (v2.510) internal audio engine at 112 (to make comparison)

Any comments, or suggestions are appreciated.

*********************************
The Devil....is in the Details

Has anybody tried this script on a higher-res encode, say 704x480? I'll try it in about, oh, 7 hours :)

not yet, but i think we can easily do that and get a great result, thinking of, what kwag´s cq51 sample looks like :lol:

Hey Kwag and friends,

There are occasional movies that I like to back up onto a DVD for compatability purposes between different players. Generally I back up 2 or 3 titles to 1 DVD+R. That being said, are their optimal filter settings (tweaks) that can be done in lieu of prediction based results of the larger file size which derives a larger CQ value. Like everyone I looking for optimum quality / speed.

I know there is somebody out there that has tried backing up 6 hours of video on a DVD @ 704x480 or 720x480. I prefer full D1.

Thanks

Morning guys!
 

I can't seem to get UnFilter working. And from what I have read, I seem to be the only one having trouble? I'm using AviSynth 2.07. Is that too old or what? Please, help me. I'm dying to try Kwag's new script out!

it works perfectly with avisynth 2.08
never used it with 2.07

Hi audioslave,

You can use "sharpen( 0.5 )" instead of unfilter. It's just a little slower :)

-kwag

Okay, I'll try sharpen. But does anyone know why unfilter won't work?

maybe a silly question, but:

did you download the unfilter.dll?

Hmm...
Seems when I unpacked the Unfilter.dll it created a folder in my AviSynth folder... :roll: Anyway, I now moved the dll file to where it's supposed to be and everything works like a charm! Sorry, for taking up your precious coding time... :oops:
Thanks again!

i had the same problem some days ago,
i´ve put all my filters in the moviestacker - filter directory

@BCHteam, what settings are you using for DCTfilter?? Could you post them for me?

Extract the Unfilter.zip file and check "Keep file names". Now have a look at the folder u"ve extracted it, there is folder named unfilter_old...
Just use this .dll (it"s the one for the avisynth 2.0x versions)
:)
