Double-posting to add more random thoughts.

Here we keep the top half of the broken field, and apply nnedi to the bottom half: http://img542.imageshack.us/img542/148/nnedi264.png
stackVertical( crop(0,0,0,240), crop(0,240,0,0).nnedi2() )
You could tweak the 240 of course. It seems to be different for each capture (Dark/Sega, X9, HF9G)


Is it just me, or these frames out of order? http://img826.imageshack.us/img826/8554/130169.gif
You might just barely see left-to-right motion in Luke's ankle.
The flash frame, with glue at the bottom, should've been last.

I've tried two decoders. First DG's old, unsupported version
then tried newest FFMS2. Both times those frames are transposed.
Chew if you're reading this, what do you get from DG-nVidia app ?

Red leader glitch is also present in X9 capture and in Dark/Sega.
Pulldown cadence is unbroken, so that's my excuse for not finding it before now.
My eyes aren't as keen as you thought yesterday :)

The last frame (155989) comprise three fields, two of which are aligned, so you could probably fix it without using nnedi.
Adjust your pulldown() parameters [or selectEvery()] to pick the first two fields instead of the last two.
The earlier frame comprise two fields, one broken, so nnedi is probably the only choice there.

In the two captures I've worked with, it was possible using nnedi to recover the following GOUT frames:
52759
55748
55751
64443
70632
86682
92800
92803
97654
100687
102746
139231
158397


Here's from the X9 caphttp://img18.imageshack.us/img18/850/156113.gif
That frame comprise three fields. Pick the first two

Help: Looking for... a good transfer of the first issue Pan And Scan Laserdisc for Star Wars
Time

The Starkiller's is on Usenet since 878 days.

Time-compressed means althor1138 will have tons of fun IVTC'ing
or go mad, whichever comes first.
Let's just say it is NOT a standard 2:3 pulldown.
I was 90% through an IVTC sript one year ago when a family tragedy struck,
and I never went back to finish. But I've still got my notes and project files stashed somewhere.

^you mean 960 nonsquare pixels stretched to fill a 1280 line?
I hope he won't do that ;-)

Is it possible to interpolate the last or first frame in a scene btw?
That would be extrapolate :) but I don't know any secrets for doing it.

Frankly I expected to see more interpolation.
You know, like where you've used nnedi2() to restore a missing field.

Both Arnie.d's X9 capture and Dark-Sega each had nearly two dozen of those single fields, all candidates for nnedi2().
You've got some of them (52719, 102649, 143934 for example), but many others I expected to see were missing.
Is your pressing that much different? It surprised me.
I could list a dozen GOUT frames to check, if you're interested.
Or if you'd show us your script then I might could translate the GOUT frame numbers, and tell you which of your source frames to check.

I'll certainly have a closer look at the shot of Red Leader-- had never noticed that glitch before. Thanks!!!
Btw is my decoder frame-accurate? Do my frame numbers match yours exactly?
155982, 155989

Thanks so much for doing these, and sharing your work.
Also glad to hear you might tackle that Technidisc ANH in future.


Now some critique. I found these, what look like IVTC anomaly:

http://img202.imageshack.us/img202/6125/06457.th.png
Frame 06457: Top field is GOUT 6457 (repeat) bottom field is GOUT 6458

http://img707.imageshack.us/img707/5558/41315.th.png
Frame 41315: Top field is GOUT 41351, bottom field 41352

http://img844.imageshack.us/img844/9629/44432u.th.png
Frame 44432: Top field is GOUT 44468 (repeat) bottom field 44469

ANH 1985 remix synched (Released)

Or rip somebody's Technidisc preservation-- it had the tractor beam mix and GOUT-sync.
Then compare and decide for yourself which of three lossy versions sounds best.

I don't suppose it even matters whether Harmy have news access,
since he already stated he don't know what to do with FLAC files any better than we do!

Who has DTS-MA encoder and knows how to use it?
That person could take Molly's FLAC and give Harmy whatever it is he needs.
If you know such-an-one with DTS-MA skillz, but don't have usenet, then I'm sure we make other arrangements....

Matt is an admirable celebrity.

Return of the Jedi - Cinch presents the U-matic telecine bootleg of 35mm (1st gen) (Released)

Yeah I saw those cue dots a few days before. No surprises there.

I've heard about baking old tapes in the oven to try and prevent oxide shedding.
Imagine it's easier done with metal reels than plastic cassettes.

Okay, so the 3Gig AVI is V1.
Then the 2Gig .WMV file on usenet could be called 1.1 ???

Why such a discrepancy in sizes? Could it be that the 3Gig is 29.97fps?
Any chance that 3G one has fewer of the blended fields seen in usenet version?

Sure I'm sounding like a gift horse mouth-looker and all,
so call me an ungrateful bastard and all the rest, but here goes:
McKayla not impressed by blended fields!
Maybe it's really N-th gen tape to begin with-- how can we know? Maybe clean IVTC is impossible.
Just wondering out loud what that 3GB file might contain, and if the unwashed masses would get our grubby hands on it.

The 1997 OT Special Edition Trilogy Preservation Standards Thread (* unfinished *)

This shows the first 'chunk change' in ANH.
The top waveform is third reel of cinema dts.
http://img163.imageshack.us/img163/1609/chunkchange.th.jpg
Bottom is schorman's AC3 rip from a North American laserdisc.
I've raised the speed from NTSC to film (48048 --> 44100)
The jagged portion at the left is the sound of Alderaxis exploding.
Toward the right is seen the hummm of Luke's green saber.

The grey box represent what's missing from the LD.
Would need to insert that much into the LD in order to match the cinema,
(or cut that much from dts to match extant video sources.)
Gray box is 4.4 frames in duration, or eleven fields in the NTSC video realm.

This next picture represents the same thing.
Frame numbers in column DARKSVN is an LD preservation, same catalog number as schorman's.
As before the grey box show eleven fields which I've inserted into the LD:

Two consectutive 3's (C10 & C11) isn't necessarily impossible but it shouldn't be that way, you wouldn't think.
Was the reel physically cut, then run through the telecine machine in two passes?
Well it's all wild-ass-guessin' at that point...
