Hi Arnie!

What software do you use for your encodes, in conjunction with CCE?

VirtualdubMpeg (but just to test the filters), dvddecrypther (only once, to rip the vobs to hdd), vobedit (to demux the vobs and split them at the vob ids to remove the first 13 or so frames of nothingness), dgindex (to create the .d2v files for avisynth), Avisynth (for the filtering), and DVD-lab pro to author the final dvd). Oh, and excel to convert frame numbers (=chapterpoints) to timecode.
Normally I split up my avisynth script into 2 parts. Part 1 contains all the filtering. Part 2 only the addborders and subtile part. I use part 1 to create an avi file and part 2 to feed the avi file to CCE. Otherwise for a 10-pass encode the PC has to also filter the raw .m2v files 10 times. This way only once.

This is a sensible approach; I do the same with scripts that involve heavy CPU use. sensible. Lagarith is a good codec for this stage because, unlike huffyuv, it can losslessly compress YV12 video.

A 10-pass encode is totally over the top. The law of diminishing returns kicks in after 2 or 3 passes, and most people agree there is no benefit in using more than 4 or 5. (I seem to remember having this discussion with you before, and you insisted you could see a difference. *cough*)

I've heard this from others also, but have no first hand experience. If Arnie.D has the time though, 10 passes at least doesn't hurt anything.

Not sure if anyone noticed, but I updated the script because I noticed some PAL resizing errors that I think I have sorted out now. Anyone in PAL land care to check them and report back?

The uncompressed avi is about 70 gb. It takes my PC about 6 hours to produce. A 10-pass encode takes my PC about 6 hours also. I don't know if there's a visible difference between 3 or 10-pass but usually I encode at night so if it takes 2 hours or 6 doesn't really matter because it's ready in the morning anyway. So I do a 10-pass just to be sure. :)

I'm doing encodings with this script. Source is PAL, here is the result of the encoding:
http://www.megaupload.com/de/?d=69Y24DX2

I'm really happy with the result of this, have not encoded more of the GOUT yet.

I would post some more encodings later, but I'm moving to another town in a few days and I won't have internetaccess for a while.

thanks for posting that Oldschooljedi! It comfirmed for me that the croping is a little off. It seems that NNedi causes some artifacts on the scanline right below the top border. I'm wondering if you crop with

Crop(8,4,-4,-2,align=true).AddBorders(6,68,6,66)

instead, if that would be better.

If you have the chance to try this and report back I'd appreciate it. Good luck with the move!

I always assumed because the NTSC version of Star Wars is sharper than the PAL version the same would be true for Empire and Jedi. But I was just comparing the NTSC and PAL version of Jedi and I think the opposite may be true. Looks to me like the PAL has a tiny bit more detail and is sharper. It also looks to me the PAL version has less "ringing" so maybe the "ringing" is introduced by the mpeg2 encoder settings. But I just compared a few scenes so I'm not sure yet this is the case for the entire movie.
I also assumed the PAL version was cropped a bit more at the top and bottom. Apparently I'm also wrong about that.

Interesting. It looks to me like there are more lines at the bottom of the NTSC and more at the top of the PAL. And the PAL ROTJ does look a bit better in terms of ringing and detail. So, I'm gonna need a PAL GOUT set for Empire and ROTJ? ;)

Well, my starfield enhancement isn't gonna get any better. Too many artifacts that have to be corrected based on each scene. So I think I'm done (yeah right).

Here is a new encoding, I used "Crop(8,4,-4,-2,align=true).AddBorders(6,68,6,66)":

http://www.megaupload.com/de/?d=A0J72XT1

This here is with "NNEDI(dh=true,field=1).TurnRight().NNEDI(dh=true,field=1).TurnLeft()":

http://www.megaupload.com/de/?d=Q01WWSE7

There are no artifacts visible at the line of the top black bar.

Any ideas how to encode with "NEEDI/EEDI2" without artifacts at the line of the top black bar?

As Arnie.d posted, the PAL source looks to me as the cropping is different compared to the NTSC source, too.

Thanks OSJ! I will download and take a look.

The artifacts on the top most line before the border is just a garbage line. NNEDI upsizes, throws away every other line and interpolates what is should be. That top most line is an interpolated line that has no good information above it so it really should just be black. I just crop it off.

About black levels, I think the tv reccomendation is just so it shows up on most tv sets which may not have the full range from 0-255. My family's widescreen tv has about 1/4th the contrast ratio of our analog rear projection. If stuff like the opening of ET looks completely black, then too bad. I don't like the idea of compromising the picture just so it shows up better on a tv. (isn't pan & scan another example of that?)
I don't know if that is the actual reason. But my video production professor told us there are legal black/white limits by the FCC in the US. He's also mentioned many times before that video basically has the wide range from dark grey to light grey.

And would Arnie be able to post his laserdisc vs Gout caps? I've seen the comparisons already here but those might be cool.

I don't have a LD cap at the moment (but I'm in the preparation stage for an awesome project).

Laserdisc? Which Laserdisc? You can't leave us hanging like that!

BTW, the script on the first page is too sharp. I'm working on a way to get more sharpness without artifacts. Stay tuned.

No. I'm already sorry I said anything. I should have waited until I had something to show...


Did anyone check out the difference between Empire and Jedi PAL/NTSC?

Here's hoping you get something to show!

Anyway, finally got the script in a place where I'm happy with it again. Update on page one.

Update to the script today! I have improved the global image stabilization quite a bit over the previous version. See the script on the first page.

Another update to the script! Now runs way faster and fixes some artifacts I found over the weekend.

Hi!

Yppie, I have internetaccess again!

I have finished encodings on ANH and used your script for ESB too. Great work g-force!

Now the GOUT look the first time watchable to me.

Thanks OSJ! Just out of curiosity, which version of the script did you use? You really might want to consider re-doing them, as the most recent version (1.05) of the script is superior to anything before it. Dare I say I'm done? I think I'm officially done!
