Ok, I got a new DVD-ROM and start new encodings. I'll post the results later.

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)

I've made some encodings with script 3.06, the artifacts stay the same like they were with script 3.05. I have no idea. Maybe I will do the final encodings with your script 2.03 or the actual one, although there are some artifacts...

The PAL version is interlaced. It has been converted from the 30fps master. Maybe that's the problem.

The PAL version is not interlaced!

what do you mean?

Both the Ntsc and pal releases of the gout were taken from a 480i D2 master tape.

Laserdiiscs are interlaced.

Just becuase they flagged the dvd as fake progressive does not make it a progressive scan transfer.

Any more than a fake resizing to anamorphic would make it an anamorphic  release.

Both the PAL and NTSC GOUT dvds are progressive. The PAL version is not interlaced. The NTSC version has pulldown flags so the dvd player plays the 23.976 fps progressive mpeg2 stream at 29.97 fps . There is no such thing as fake progressive flags.

g-force,

in your current script you write

"Function Contra(clip denoised, clip orig)
{# re-write of Didée's contra sharpening routine from TemporalDegrain.avs"

So do I need the hqdn3d.dll-plugin as required filter for this as described here?

They de-interlaced before mastering the DVD. And they did a terrible job at that, as witnessed by the poor vertical resolution and jaggies compared to the laserdiscs.

No, no need for that plugin.

I have a new theory as to what is happening. I think you may have a newer version of MVTools than I have. And that isn't necesarily a bad thing. BUT, here's the problem:

I encoded my newest version of the code and everything looks awesome EXCEPT when Luke lights up his lightsaber in Obi's hut. There is an annoying blur around the lightsaber. So I did some experimenting, and found that if I did a more accurate (but slower) motion estimation, sure enough, that blurring was much less. But now, with that better motion estimation, the motion vectors are locking on to the DVNR smearing that is present. The most noticable problem area I have seen so far is the Greedo scene. On the original, one can faintly make out a ghost of Han when the scene switchs to Greedo. So now when I make the motion estimation better, the algorithm locks on to that ghost and re-inforces it, making it even worse. And this looks very similar to the screen shots of the scene changes that OSJ has posted.

Bottom line is, there may not be a way to have both good denoising and little artifacting due to the DVNR smearing. I mean, I'll keep working on it, but things are looking not so good at the moment.

This GOUT is getting worse all the time.

I used mvtools 1.9.2 you used mvtools 1.9.3. I've tried both and learned that it makes no difference.

I started to encode the scene I posted with screenshots further again,  to be sure, I have not used a wrong plugin.

So I downloaded the plugins as you postet for download earlier here. The result was the same.

I noticed just as much aliasing (jaggies) on the LDs as I did on the DVDs. 

However, the fuzzier nature of the LDs (depending on the player) covers a multitude of sins. For that reason the aliasing on the LDs may be less noticeable to some.

The tired of gout attacks, ad at the bottom of this page that is now gone was too funny. 

Not that real gout is funny but that the Lucas gout dvd was an attack on oot fandom.  and That there might be a cure, lol.

They did not deinterlace (otherwise the framerate would be 29.97fps). Instead, they carried out IVTC, which is of course the correct way to do it.

It is true that there is a degree of aliasing present on the NTSC laserdiscs. Laserman once said he thought they were caused by a minor field misalignment in the telecine. The PAL laserdiscs which come from a different transfer are better in this respect, and don't show so much aliasing.

I'm not a professional, but it looks to me as if whoever mastered the DVDs applied a vertical blur in an attempt to mask the aliasing. Unfortunately, this not only resulted in a loss of vertical detail, but has actually made the aliasing worse in some locations.

To add insult to injury, the Region 2/4 PAL DVDs were upscaled from the NTSC master, intead of using the PAL master that the French/German laserdiscs were made from.

Oops, your right. Got my terms mixed up.

Ha! I had forgotten about that. That was our "last hope" for salvaging something respectable from the GOUT. Yet another reason it was a slap in the face!

It also seems worse on the SW LD/DVD than it is on the ESB & ROTJ discs, for some reason.

Okay, I think I've figured out a fix. OSJ, please try the new script on page one and let me know if that works for you.

Thank you, g-force.

The encoding is running while I'm writing.

I encoded 2 chapters and they look perfect, exept the left side of the picture. When you look frame by frame at the scene it looks, like the things that come into the picture would "ghost" into the scene from the left side to the center and disappear then.

Here I posted a short clip, because I don't know how to describe it exactly.

I tried to use other denoisers with your script the last few days, but avisynth doesn't seem to be my friend; I had no luck.

Well, I'm glad we're getting closer. I'll take a look at the clip you posted when I get home tonight.

Thanks for reporting back!

So are these script fixes just for the PAL version or are they overall improvements for the PAL and NTSC?

 

everytime I get around to encoding LOL there is a new version.

 

I will be doing an NTSC verison.

You can use this script for both NTSC and PAL.

In the first few lines of the script you can read

PAL = false       # <-----Set to false for NTSC, true for PAL

If you want to do a NTSC-encode, change nothing there, if you want to do a PAL-encode, change the "false" into "true".

Yeah, I'm always trying to improve the NTSC version, but OSJ is helping me sort some bugs with the PAL version. I would hold off until all the bugs are worked out with both versions because there may be some bugs I'm not seeing in the NTSC that are more apparent in the PAL.

I see the problems that you are referring to, but they are not showing up when running the script on my NTSC version. OSJ, could you post the original of the clip you just posted?

thanks,
