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

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:

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.

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 :!:

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)

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:

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.

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 ;)
