Well I'm sorry to be 'that guy' again

 Yeah I'd rather have known before I release it again.  Thanks for the help! I was about ready to fix everything and start encoding but I guess it can wait a few more days lol. 

I was using selectevery and manually throwing out the frames but moth3r showed me this:

dw=avisource().assumetff().doubleweave()
a = dw.Pulldown(0, 2).Subtitle("0, 2")
b = dw.Pulldown(1, 3).Subtitle("1, 3")
c = dw.Pulldown(2, 4).Subtitle("2, 4")
d = dw.Pulldown(0 ,3).Subtitle("0 ,3")
e = dw.Pulldown(1, 4).Subtitle("1, 4")
show=ShowFiveVersions(a, b, c, d, e)

return(show)

I found it to be quicker and easier to spot which pulldown to use with the showfiveversions filter.  I imagine the same thing could be implemented with the selectevery method also.  Are there any benefits or drawbacks to using either method?

EDIT: I'm really hoping you guys don't find so much wrong with ESB or ROTJ lol.

selectEvery() is better if the source is YV12. Yours probably isn't.

I will have a few more ESB frames to check. Haven't seen ROTJ
so if you want help with that one, show your script!

Mattman, don't be alarmed if your SWE don't have all the same cadence changes.
Not long ago poita shared the first reel of his SWE cap which had only two cadence changes. (JSC had four changes within the first reel.)

EDIT: I haven't even started ROTJ yet btw.

I used several avs files for star wars because it was so many changes and lines but I used one for ESB so here it is:

I don't understand why this is the case, because Pulldown() is implemented using SelectEvery() internally.

You learn something new every day...or night. It's nice you're helping out with this Mallwalker!

I like the idea of using a function.  It would save a lot of typing.  I like typing so it never really bothered me that much but if it makes things easier to understand then it's worth it I think.

Here is a little clip.  It is interleaved with 1 clip being the raw capture and the other being the adjusted clip I plan on using for the 720p version.  I've just adjusted the levels and tried to not crush or blow out any information.  I have applied a halo reducer which I think I'm going to use.  I wouldn't say it fixes the right-edge halo problem but I think it makes it better. 

Hey, what's up with the "strobo-effect" or is it only a problem on my end? And how do I get to check the 720p version??

It alternates between the raw capture and the settings I planned on using.  You should probably not watch this temporally but step through it.  I just wanted to see what people thought of the settings.  I haven't done the 720 yet.  I think in a couple days I'm going to go through and double check everything that has been pointed out as wrong and fix it.  Then I'll encode the raw 480p and then I'll add the tweaks and upsize to 720p.

Yeah, stupid me... it took a while before it hit me. Sorry, I'm really slow today. :)

If you want an epileptic seizure, I can recommend it. Anyway, the sample looks great, the reduced haloing is nice. What filter are you using for the dehaloing?

I used several successive calls to generalconvolution to create an edge mask on the right side of bright areas next to dark areas and then shifted the mask over to match the right-edge halo of my laserdisc player.  Then I used overlay with the mask and mode="multiply" to get rid of the halo. This isn't on every disc though so I guess it's combination of the laserdisc and the player which creates this sometimes.  On ESB and TPM it's not very prominent like on SW for example.

source=avisource()

conv1=conv.converttorgb32().GeneralConvolution(0, "
   1  0 -1
   2  0 -2
   1  0 -1 ", 8)

conv2=conv1.GeneralConvolution(0, "
  0 0 0 0 0
  0 0 0 0 0
  1 0 0 0 0
  0 0 0 0 0
  0 0 0 0 0 ")

conv3=conv2.GeneralConvolution(0, "
  0 0 0 0 0
  0 0 0 0 0
  0 1 0 0 0
  0 0 0 0 0
  0 0 0 0 0 ")

overlaymask=overlay(source,conv3,mode="multiply",mask=conv3.converttorgb32().mask(conv3.converttorgb32()))

return(overlaymask)

Fixed the following GOUT frames:
15592 - was combed, see Post_98 above
30739 - was nnedi()ed, but two fields are present
30745 - was missing, but it's nnedi()able

Please check this field:
side1raw.separatefields().trim(82191,-1)
Does it contain Han or blackness?

If Han, then add this line:
s1p33=side1raw.separatefields.trim(82191,-1).nnedi2(dh=true).assumefps("ntsc_film")
to restore GOUT 32186


Moving on to side2, please check the following fields:
side2raw.separatefields().trim(804,-1)
side2raw.separatefields().trim(102203,-1)
Do they contain picture or blackness?

 

Thanks for this.  I've checked the Han or black frame and it contained Han. ESB was very easy to IVTC compared to SW but I can see it needs some fine grooming as well.  What a total mess this set is.

Nice, thanks for that. I think most of the edge-enhancement artifacts we see is present in these transfers to begin with already, I don't know how much more work you're willing to spend on the 720p but you could easily improve the look of it if you wanted by just correcting the chroma shift in it, think it's most visible in the first few reels... good examples are the red wall lights on the blockade runner, the red light of Artoo in the canyon and the binary sunset, but I recall the shift isn't off by the same amount from scene to scene or is that constant so it may be a little tedious work.

http://www.geocities.com/siwalters_uk/chromashift.html

an example I did on arnie.d's cap to demonstrate the ugly bleed/shift in it, not perfect but definitely an improvement. Just a suggestion... hope you leave the 480p unfiltered.

I could continue to tweeze this, but must be past the point of diminishing returns
so instead I'll just turn it loose:

I've been capturing all of the other Star Wars laserdiscs that I own.  That is complete now.  I think what I am going to do is put the raw files on usenet.  I so far have captured:

JSC trilogy

DC trilogy

SE trilogy

The Phantom Menace

Wow, cool! Thanks!

I'm currently posting SW to the newsgroup.  The first post should be finished in a couple of hours.  This is my first time posting so please bear with me.  The first post will have some incomplete files because I messed up the upload a couple of times but I've re-uploaded them so everything should be there. 

Thanks for the feedback!  If there is interest I'll be uploading the rest of the trilogy and probably the 97SE trilogy as well.  I see no reason to post the DC.
