Okay, I've finally got some good degraining that I'm extremely happy with. Check out the new script!

 Thanks for all of your work on this g-force.  Are there any new avs filters needed for the new script?

There shouldn't be any new filters needed over the last posted version.

-G

g-force,

would you say that the script version 2.03 is the final script or are there some more improvements since this script?

No, unfortunately this is not the final script. I'm working on an even better denoiser using a mo-comp'd median function with a larger temporal radius. Expect an update in the next week or so.

-G

OK G-Force,

I am ready to give this a shot,I have my new super computer up and running now,so is this the latest script or is there another coming?

Well here are some screens from your v2.03 version for now,I will delete these in a couple of days as to not take up to much room.

I also have a video_ts sample,and here is the lnk if you want to see it:

Here is one of my encodings with script 2.03.

I encoded all movies and after I did do some testencodings with the actual script I know, I have to encode them again.

Often couldn't imagine there was more tweaking possible in the script, but g-force told me better. I tried to write an avisynth script for the GOUT before g-force started this treat,  but I was not very successful.

Thanks for the screen shots DJ! Something I have never been very good about.

I really do like the results of v. 2.03, but it seems that if you get rid of all the "crazy" amount of grain in some shots, there is a residual amount that is persistent from frame to frame that seems to move along with objects. It's mildly annoying, so I will be getting rid of even more grain in the upcoming version. If you want to see what I'm talking about, make some screen shots (before and after) of Ben sitting in his hut right after he sees the Leia message. If you think that's a lot of grain removal, just wait 'til v. 3.00! I still have a couple very minor bugs to work out, and I'm going to need to upgrade the RAM in my PC to get it to encode in a decent amount of time. Stay tuned!

-G

Okay, I've finally got an update worth reporting (see page one for most recent script). And here is the shot I was referring to.

looks good,now to try out this new script.

So is this the final?

 I think so, but I can't promise that until this one is encoded and I move on to ESB.

-G

fair enough,looking forward to ESB,my favorite.

I have just encoded chapter 15 and I'm really happy with the result. I will do another encoding with chapter 19. Chapter 19 and chapter 5 was always my reference-chapter for the testencodings.

G-force, I like the idea, that everybody can do his own watchable DVD with your script maybe with custom DVD menu and the audiotracks one prefers. So this is a real big thing for me.

You don't need to burn a custom DVD, media player classic supports AVIsynth scripts for realtime playback.

Yes, but only if the script runs in realtime! ;)

g-force,

I've done some testencodings and I'm getting some errors. Here are some screenshots:

Here I did do some markings arround the area I mean:

Here is also a short sample-clip:

http://rapidshare.com/files/148657334/1.m2v.html

Did I use a wrong avisynth-plugins again? I'm actually using the plugins I used the last months for the encodings.

Because I prefer selectable subtitles, I did change your script a littlebit:

Maybe the error is caused by changing it this way? Any ideas? To me it seems, that the error is only at scene-changes, but I'm not sure, if it has something to do with it...

OSJ, that truely is ugly! Let me investigate and I'll get back to you. I doubt the changes you made are the culprit. I have an idea what may be causing the errors, and if that's it, I know the fix. I'll get back to you with a fix within the next couple days.

-G

Oh, thank you very much!!!

OSJ,

I have taken a look at those frames, and although they are showing some artifacts, they aren't as bad as the pics you are showing. There must be some differences between how the PAL reacts to the script compared to the NTSC version. So I have updated the script yet again, and now am not getting any artifacts on those frames. Could you check the new script (on page one) with your PAL version and report back your findings? As a side benefit, there is now even more noise reduction!

(fingers crossed)

-G

Thank you, this is very kind from you.

I will post the result, starting to work with the script at the moment.

OH, SHIT! I can't rip the movie on my HDD. My PC is quite new and the DVD ROM is already damaged. According to the servicehotline I will get a new DVD drive in about 5 days,so I can't do a testencoding at the moment. But I test it as soon as I can. 

I could smash this PC against the wall!!!!!!

"Doh!"

Man, that sucks.  More in the line of the Annual Computer Curse that seems to be going around.  Remind me not to start my projects until this blows over.
