Laserschwert, thank you for dissecting my screencaps today and suggesting all of these filters. Seriously, it's great to have someone like you come along and tell me what I could be doing better, I appreciate it.

I'm going to play around with these filters you have mentioned. I've tried out guavacomb, but the rest of them are new to me. Hopefully I can correct the haloing problem. Even if it ups the brightness a bit, it's not that big of a deal since I can always adjust that when I color correct in Premiere.

More screencaps coming tomarrow...

By the way, Zion, there are still several artifacts I notice on your screenshot. One being a slight "stairstep"-effect on diagonal lines. Did you deinterlace the source? Another thing being a slight ghosting effect... you can see this effect very good on the screenshot of Luke at the homestead watching the binary sunset. The ghosting shows as a slight dark shadow of the video itself, left of Luke's head. There's a good filter to fix that contained in TMPEG, so maybe you might want to take a look into that.

Furthermore, your image looks a bit fuzzy... I guess some sharpening would be appropriate here. Since you're using AviSynth inbetween, I would use the WarpSharp package for it, and add these commands to your script:

Lanczos4Resize(720 * 4, 480 * 4)
XSharpen
Lanczos4Resize(720, 480)

Maybe some noise reduction afterwards would be needed. The video size, of course, depends on what you work with, but I guess you're working at this resolution.

EDIT: Mmh... I guess the first thing should be the removal of the ghosting effect (it would only get worse when sharpening and filtering the image with the ghosting)... although I don't know if there's a VirtualDub-plugin for this. After all, you can't do it in TMPEG, since TMPEG is your last step.


Yeah, that "stairstep" effect bugs the hell out of me. I'm going to mess around and see if I can get rid of it tonight. I've never heard of the warpsharp package, but I'll take a look at it. I'm already employing a number of filters including noise reduction and sharpening. I'll post a few caps of my raw capture to show you how much better the finished product is looking.


As for the black bar issue, you guys pretty much already said it. They have to be encoded into the video.

lol, I was wondering how long it would take people to notice that. I actually goofed when I imported the video into premiere and as a result, it resized to 720, but cut off the sides. On my new test mpeg (which looks better btw) I have corrected the problem.



yourmother:

On a regular 4:3 tv, anamorphic looks exactly the way any widescreen movie looks - it has the big black bars on the top and bottom. Since the Star Wars Trilogy was shot with a 2.35:1 aspect ratio, it will still show bars on a widescreen tv because it is actually WIDER than 16:9. Those bars are normal, and yes mine will also do this.

My transfers will look as close to DVD quality as I can make them, but I'm not going to go out of my way to make them look like the DVD's. The official DVD's were transfered straight from the original negatives and employ color correction techniques that I cannot even fathom. There is no way to get such vivid color off of the LD transfers.

As for the cover art, I used Adobe Photoshop. Anyone could whip up a decent dvd sleeve with enough patience and know-how.

yeah, it's probably CLD, not CLC. the text is scratched off on that letter on my player, so I just guessed. As far as it's quality, from all the research I did before I purchased one, this was in the top 5 of all NTSC LD players for picture quality and durability. It is a commercial model, and built a little tougher than the models you'd find on store shelves. The guy I bought it from got it from his company, which was upgrading their A/V training materials to DVD. It's an awesome player, I just wish I had the damn remote.

BadAsh - great post man. I wholeheartily agree.

The haloing (sp?) was there from the raw capture. I don't know if it's something that my LD player is introducing into the signal because it's old, or if it's a cable. I don't think it's a cable because I've tested it out with two different Monster Cables, and got the same result. It shows up a bit better than it should because of my sharpening filter, but it's a necessary evil since the sharpen makes the whole video look a hell of a lot better. I'm leaning towards two causes on this: A) the haloing is there on the disc, or B) my video connector is at fault. I'm leaning towards B because the connecter is loose, and upon further inspection the connecter loses the signal completely if I move it around enough. I may end up trying to acquire a new player if this becomes more of a problem.

Upon closer inspection, when viewing the raw avi, it appears that the haloing is a ghost of the previous frame. This means that it only shows up on things that are in motion, and it only lasts for one frame. I really only noticed it on the video because I was watching for it, so I would have to say it's hardly noticable at all, much less a distraction.

mistertones - Great idea. I've got a 4 day weekend coming up, so I'll probably have something up by Monday at the latest. Most likely it'll be a 2-3 second clip, full quality mpeg2.


Edit:

Upon even closer inspection, yes, there is some slight haloing on black objects (ie vader, leia's hair) that is also coming from the raw capture. This may also be a result of the video connector on my LD player. I'll try using the S-Video jack and see if it's any different.

And another thing I just noticed, looking at MEBEJEDI's captures, the halo is there also. Is it possible that all Faces LD's have this flaw?

Gavin-,

It all has to do with that little thing called aspect ratio. You'll notice that on both the TR47 and ISOMIX caps, they are both the same size. To my eye, they both appear to be straight transfers from the original source without any resizing. The reason they look squished is because the size of the pixels of 4:3 video are actually .9 rather than 1, if that makes any sense. On your television, they don't appear squished like that.


Zion why do you say we can't do an LD faces benchmark to compare these transfer along with potential restoration. Wouldn't that be the best way to see what is potentially lost in a transfer and what is added with color correction and clean-up? Its hard using the 2004 set as a mark when that cleanup process involves the 9th biggest supercomputer in the world with 1000's of Mac's daisychained...Lowry's work is pretty spectacular.


I only say that because a raw capture of the LD's looks really crappy to begin with and it will look different depending on who captures it and what software and hardware is used.

Compare them to what? A picture of someones TV screen?

There really is no LD benchmark to compare them to, that's why Ash has the official DVD screencaps to compare. Those are the closest thing to a benchmark we're going to get (and a damn good one at that).



Oh yeah, I just sent Ash some screenshots to compare to the ones above. I'll let him post them, but here's one you can digest in the mean time:

I've never heard of PCM being a standard either. I always thought that some form of DD (2.0, 1.0, etc.) was the minimum standard for all dvd's.

What if the "spot" is from the laserdisc material itself?
Then it is a spot which came from the master and will be on all three captures, thus ending up on the output video. In this case, like noise, it will go through filters that will remove most of it, if not remove it completely. Spots like that are much less noticable during playback than big rainbowy laser rot spots.

Also, will you be encoding progressive, or interlaced ?


Progressive. Don't question it!

Ash, that's probably why DVD requirements say you have to have a DD track as a minimum. That's a good point, and I'll probably keep that as the primary audio option, unless I do a 5.1 soundtrack.


Class316, the movie footage is from the Faces set. The only thing I'm using the Definitives for now is the bonus materials.

In order to achieve a rot spot free transfer, there is an AVIsynth filter called "TOOT" that will check three separate sources of video pixel by pixel and average the two most similar. So, for instance if I make three captures from three different ANH LD's and on one frame one has a rot spot and the other two don't, the output video will be without that spot. Using this method, I should be able to produce a transfer that is rid of all rot spots.

Not a problem. Just don't use the ones that are on my site at the moment, as they are not from my faces transfer. I'll pm you with new screenshots, just let me know which frames you want.

The reason why I'm focusing on ESB right now is because I don't have a copy of the faces version of ANH. I've got one coming in today though, so I'll have some screenshots made up for those ANH frames this week.

And one suggestion if I may. For the ANH frames you have up, it would really be more comprehensive to have some different scenes represented. Perhaps instead of three frames from the same scene, you could have a few different ones that would display how well the transfers do with dark scenes, bright scenes, and colorful scenes.
