No apology is necessary.  I know the feeling!

The real reason I asked about the YUV version is to circumvent the colorspace conversions.  Going to RGB and back once is fine, but the multiple conversions still worry me a bit, which is why I wondered if the existing option to apply the difference between two clips to a third would be one solution.

It's a shame Avisynth is 8-bit only.  A 32-bit workflow would help here.

By the way, I don't think I've sent you any e-mails that you haven't replied to.  :-)

g-force said: I'll make an updated version after Christmas that has all the options of both scripts, and maybe a YUV version as well.

Hey, g-force.  Are you still planning to work on a YUV version?  It would be really useful. 

By the way, does the option to determine the correction from two different sources and then apply it to a third get round the numerous colorspace conversions in the script?

You mentioned adding the option to balance the black and white levels to an updated version of the script.  Would it be possible to write a script that matches only black and white levels i.e. makes no color changes?  Could this be used to correct a source with a brightness-and-contrast problem by using another source or does it not work like that?

selectEvery() is better if the source is YV12.

I don't understand why this is the case, because Pulldown() is implemented using SelectEvery() internally.  Is it just that it is easier to spot problematic frames with SelectEvery()?

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

 

It's better to be "that guy" before the fixed version is released than after. :)

msycamore said: Differences in tints shouldn't imo be confused with a whole new timing done,

I see.  You mean a difference such as the one between the Final Cut and Director's Cut of Blade Runner.  I am not sure that I would be that exacting in my terminology, but I understand you now. :-)

And who is AF?

Sorry. By The AF, I meant our friend The Aluminum Falcon.  Excuse my lazy typing. :D

Eight times in a week!  Wow!  That's more showings than there are days.

I don't like the new color of Superman's costume either.  Apart from that, though, I like the look of the theatrical BDs of I and II, and the costume's an easy fix with selectivecolour() and Avisynth.  I don't care much about III and IV.

You're welcome guys, and sorry if I ruin some movie magic for some others.

Even knowing what's been changed doesn't really prevent me from enjoying my wowow cap.  With the original jeep shot back, I'm happy.  The changes are simply not on the level of the changes to SW (though I agree with you that there are undoubtedly others that have not been noticed).  And would any of us really spend time trying to add those few marks back to an HD image?

To me all three have the same timing, they differ yes, but I wouldn't call them completely different timings.

Obviously, this is subjective, but I can see a substantive difference between the Laser Pacific transfer and previous releases in terms of color.  It's not huge, but I would say it counts as a different timing.

The AF is the one to ask about the different transfers though.

I would really like to know what the source is for the JP comparisons.  Apart from the DNR on the 3D version, which is indeed bad, and the fact it seems very bright, I actually quite like the colors.

A film that I want with the original colors and the original aspect ratio is The Voyage of the Dawn Treader.  I don't hate the color on the BD, but I prefer the way the film looks here in the screenshot at the bottom.  It's one of the few instances in which I prefer the version that looks more cyan.

Thanks for the comparisons, msycamore.  The red rings really helped, as otherwise I might not have noticed.  I had to look for a bit before I was sure that I could see the pole.  What's the source of the untweaked shots (apart from the trailer)?

msycamore said:  You asked in the Terminator thread about the changes I mentioned, I can unfortunately not provide any comparisons until the end of the week when I get home,

I'd be interested in seeing those.  Apart from the jeep shot, I don't think I've seen before-and-after comparisons of the changes.

Darth Mallwalker said:  Chew if you're reading this, what do you get from DG-nVidia app ?

On althor's MKV?  DGIndexNV shows the same thing.  The flash is on 130061.  I used the 720p stream, but it shouldn't make a difference.  My eyes aren't good enough to make out the left-to-right motion you mentioned though.

EDIT:  Is the GOUT the same?

captainsolo said:  I had heard about the Superman BDs having color shift but never knew any details.

Have a look here.

^  It looks like recompressing the 3D BD is a bad idea then.

Harmy said: Also, did you notice that the teal shift seems to be more pronounced in the 2D version? I would be fine with them making all these changes (except for the color) to the 3D version, because that is already altered by just being 3D but they should have left the 2D version well alone. I'm seriously a little pissed off right now :-/

2D vs 3D

There are slight differences in color.  Of course, if you prefer the look of the 3D, you could always demux the left-eye stream, add the mattes back and re-encode with x264.

You_Too said:  From what I've seen in screenshot comparisons here and there, the Japanese BD is the same as the HD DVD, but also has cleaner upper and lower edges of the picture. The HD DVD is bright and blurry at those edges.

I looked at the screenshot comparisons a few years ago and seem to remember that the Japanese BD is slightly stretched vertically (like some of the others).  I have the Japanese discs and the theatrical HD DVD, and the difference between the Japanese discs and all the other non-Skynet releases is minor.  It's down to individual impressions of small differences in grain and of the degree of edge enhancement and the like, and I'll take the HD DVD.  In my opinion, the Japanese discs aren't significantly better than the other non-Skynet releases (as some have made them out to be) and weren't worth the price I paid to import them.

The DTS-HD MA 2.0 on the theatrical BD sounds very good to me.  Wasn't there some sort of mono-to-stereo effect originally in the opening credits?  I don't know what the LD audio is like, but I'm happy to have the stereo mix that's on the BD.

Harmy's right that the (theatrical) HD DVD looks the best, but there's not much in it really.  Basically, all of the old BDs and HD DVDs look very similar.  Anything's better than the Skynet release.

You_Too said:

Ok, if a Terminator 2 remaster is on the way, this is what I bet it will look like, old vs new: 

I imagine it would look almost exactly like that.

That sounds fine to me.  :-)

Okay. I didn't realize that.  In that case, I think that Frink's right and that he should probably be banned.

I agree.  The words are definitely "over" and "sit down".  It's never occurred to me that they could be anything else.  They're a bit indistinct, but clear enough.

Harmy's right.  Let's drop it.  I hope that he enjoys the Blu-rays as much as we enjoy the Despecialized version and that he realizes that he is wasting his time.

EDIT: Who do you think it is, Frink?  I never thought that he might be a sock.

Thanks.  Good luck syncing the CDS track.

That makes sense.  When I saw your script, I wondered if what you were doing might have been inspired by Spaced Ranger's post here.  You_Too and dark_jedi have essentially finalized what they are going to release, but perhaps some of Spaced Ranger's ideas could be applied to this project.

What does CDS mean?

Ah, so you're denoising each channel separately!  When you uploaded your last clips, I did wonder why you were converting to RGB, but now I understand.  (I don't have a problem with converting to RGB if it helps, and what you've done seems like a good idea:  I just wondered why.)
