I see what you mean

As late as last page in this thread, I explained why the GOUT can't be corrected to look like the original prints.

Of course I would want it to look like the technicolor print but it's impossible since the colors are not separated from each other in a way that would allow that color correction.

Of the three in the GOUT, the most limited would be SW, and I think you both have managed to pull out everything possible there.  But damn ESB and ROTJ look good! I never thought that something like that could be pulled out of the GOUT. Now if only there were a magical anti-motion smearing button. ;)

@captainsolo: Thanks!

And yes, please somebody invent a magic anti-smearing plugin for avisynth. :)

I kind of understand why they did the DVNR back then though. It was probably considered state of the art back then, as it did remove lots and lots of dirt and stuff, which can clearly be seen if comparing it to msycamore's Technidisc capture.

And back then, people were used to see smearing on TV. Basically everything shot on video had smearing.

Of course I still dislike the smearing very much, but I understand how it worked to release this back then.

Would it make sense to treat this DVNR smearing as motion blur? If so, we might be able to take some stabs at it.

(One thing I did notice is that the smearing is only present in the luma. I experimented a few weeks (months?) ago with using affine image alignment to spatially-align the Technidisc capture to the GOUT. After doing the alignment, using the Technidisc's luma with the GOUT's chroma resulted in a smear-free image.)

If the smearing is only present in the Luma, wouldn't shots like this look a bit more weird, like the color not matching the double eyes of the stormtrooper?

You would think. That's why I found the results to be weird.

@AntcuFaalb: It doesn't only show as motion blur, it sometimes make moving things appear doubled or leaving trails of itself and things like that.

But it does sometimes show as motion blur, so maybe a de-motion-blur filter of some sort can fix things up a bit. Do you know of any we could try?

I can only say wow, you were right. They only DVNR'ed the luma.

Yeah, I did quite a bit of experimenting for my now-defunct SWOLT project. Isn't it weird?

Most defects (e.g., dirt and dust) exist in luma, so this probably made sense in the early '90s as a way to reduce the required time for processing.

It would take some insanely intelligent plugin to see the difference.

Agreed, but what do high-end video cameras use? They seem to be quite intelligent...

Are you going to take advantage of this at all?  Applied carefully and selectively, it could eliminate the worst and most noticeably smeared shots in the GOUT, and that would definitely be worthwhile.

Unfortunately it's not possible since the Technidisc's picture seems to be warped differently, and the resolution of the GOUT's luma is better so it would be too much of a downgrade in quality.

We will keep working with what we have, and we'll have to live with the smearing.

The distortion differences are easily solved by BunwarpJ for ImageJ. This technique can greatly improve the infamous speeder shot. Want me to hack at?

Whoa!

Indeed, selectively would be the word to use. The idea is awesome, but in practice as U2 pointed out probably not very feasible. Still...that quick try on ol' 4 eyes gives hope.

Working on the infamous speeder scene now. It's coming out great!

To see the Huffyuv-encoded (sorry, I'm lazy) AVI sample of the aforementioned technique applied to the infamous speeder shot: click here. Make sure to only click the "Click here to start download from sendspace" link, as all the rest are spam.

Notes:

• The bottom is, obviously, what you should be looking at.
• I only did minor cleanup using my RemoveDirtMC script, so there's still some defects/dirt/dust hanging around. These can be fixed with, e.g., Photoshop.
• The affine image alignment forced me to crop a bit from the end result.

Enjoy!

man, this looks pretty promising so far.  definitely helps with the smearing.

The background buildings in the bottom 'fixed' clip look much more fixed, solid, stable, less blurred. Am I seeing that correctly?

Yes, you are. The black-and-white (i.e., details) portion of the image is entirely from the Technidisc LD preservation. No magic was applied :-)

Yes, but it'll have to wait for later on tonight. I didn't mean to derail this thread!

No.  It is not good.

While the buildings have cleaner edges, the fine detail of the shot suffers. 

Windows in the buildings are more blurred and the speeder and its occupants are less distinct.

Since this is upscaling to HD, sacrificing detail seems like a bad idea.
