I like laserdisc colors most! Is the capture taken using the software decoder?

This is captured with the theater750pcie.

Luke threw twice…maybe.

OK, thanks. What's about the "pyramid" set? Have you noted the pink tint is present only in about half of the scenes, scattered randomly throught the whole movie?

I've noticed that and also that it's not a very good pressing.  It does seem to be free of dvnr but it's not high on my list of favorite laserdiscs because of the poor quality.

It has "hidden" details to be discored, though... found a small clip of Mos Eisley, taken from the pyramid and the German THX laserdiscs; working on them to extract every single subpixel as possible... (^^,)

Tweaked my software to do color LPF after chroma is added into luma for the actual comb filtering.  Didn't get around to doing a wide-output mode, but I figure I'll look at a thing or two more then jump back into PAL.

That's great happycube! Sure you'll be able to fix the output width!

About "pyramid": I found the Mos Eisley shot, and here it is better IMHO than the THX DE in several way:

so I took the former, cleaned, upscaled, freely regraded, and slapped a grain plate over it:

not bad, for a 20 years laserdisc using a bad master...

Looks so clean after your processing. What did you use to achieve such an outstanding result? One of your magic filters? :D

Probably nothing new but I noted a very similar color grading between the THX-PAL and a promotional still I found.

THX-PAL: http://s25.postimg.org/yhft4cqq7/goutvsldpal3.png

Still: http://www.moviestillsdb.com/movies/star-wars-i76759/6fbb6191

I'm not saying either of them is color accurate, but I wonder if teal indeed was to be so prominent in that shot in the theatrical version. Maybe the THX-PAL is indeed closer to the original.

Wow, Andrea that was quite impressive indeed! This LD is really important to my eyes, even if it has an horrible pressing and weird colors I really enjoy watching it. Have you considered capturing the whole movie then apply the same treatment to it? It would be quite interesting.

I don't have the Pyramid box set but I have the first Gold edition which uses the same master as you already know :-)

I thought to do it, but first I must find a way to let the capture chain work again, then buy a new HDD to contain this, and many others, half-finished projects... now unfortunately it's not the right time, but I hope to see better days soon!

@ Laserfisc Master

That cleanup looks really impressive indeed! 

Author

Yeah - very nice cleanup!  (and I added an option to my comb filter to output 844 wide, which should cover everything except the burst isn't getting copied in)

I'm thinking collectively there's a good chance something along the lines of the X0 project could happen again, this time with more stuff/techniques in the open.  (How is Laserman anyway?)

Alive and well.

I’m late to the party, but I think this is the best song. Enjoy!

DrDre, happycube: thanks!

AntcuFaalb: a certain laserman signed up on fanres; don't know if he's the same person, though...

Speaking of cool members, does anybody have news from poita?

I hope he's okay, He hasn't post for a while.

Yep, he's fine, but really really busy. I just spoke with him yesterday.

Oh, good. Glad to hear it!

Current work: I think the best solution to LPFing chroma in an edge-preserving way is to LPF luma to a really low frequency (down below the chroma mix-in point), run a good edge detection algorithm (e.g., Canny) on it, and then not blur across those edges.

We can't use the chroma channels for edge detection because (1) we're LPFing them in the first place and (2) the rainbows will show up as edges.

Thoughts?

A good frequency to LPF luma down to would be ~3MHz.

The reason we want to LPF luma before edge detection is that we want to get rid of the high frequency detail that caused the rainbows in the first place!

NOTE: The LPF'd luma would only be used for edge detection and wouldn't be included in the output, of course...

Still think the inversion-phase trick could work best - even if we should capture a disc twice; still got to find out a way, hardware or software, to properly produce it, though...

AntcuFaalb:  Only downside of that is chroma shifts at the same luma won't be picked up.  It might be good to search for the rainbows as well I think.

Also 3mhz is too high for later disks with ~1.5mhz+ chroma resolution.  Somewhere between 1.5 and 2mhz would be good for all disks.

Do you have an NTSC spectrum graph for 1.5MHz I and Q? All I have is the one for 1.5MHz I and 0.5MHz Q.

This is certainly good news to my ears because I signed up on this forum while he was still here.

It'd be awesome if the whole movie was anamorphic!  (But I have doubts, it might cut to regular size after the first shot transition)
