[Solved]: Barry Lyndon English mono from Criterion BR |

Hello,
For my Stanley Kubrick's "Barry Lyndon" restoration project (for German localized version), I would love to include the English mono audio track.
This is contained on the Criterion Blu-Ray. Alas, I only have the Warner BR with the 5.1 audio.
I would be grateful if anyone could share it with me.
Edit: Got it.

First Strike (1996) Uncut (Laserdisc rip) neural network |

Hello everyone, this full version of the film is most likely not when it will not be released in full HD quality, and the DVDs that are on the network are just awful, I apparently have captured from the Hong Kong Mei Ah Laserdisc but it has Chinese and English subtitles that cannot be turned off right away. Perhaps someone has good copying from LD without such non-disabled subtitles?
I plan to make an upscale with LD 1080p using the neural networks of the Topaz program and its successful Gaia processing algorithm - CG 5

ColorMatch 3D (new colormatching tool) |

Just something I was working on:
https://github.com/TomArrow/ColorMatch3D/releases
Give it an input and output image. Hit the red button, wait, then click the export button.
Benefits over DrDre's colormatch:
- Blazing fast. Depending on image size and your CPU, it can be less than a second
- Should be able to deal with more complex changes in theory due to a completely different algorithm
Downsides over DrDre:
- Doesn't generalize well. It will only match the colors in the image and no others, so applying the LUT to any other image will result in garbage. It might not even generalize well across an entire scene, so its use currently is to match single frames and maybe very similar frames.
Todo for the future:
- Try to integrate some interpolation option to make the 3D LUTS generalize better.
- Create an AVISynth plugin
The algorithm is childishly simple: Create an RGB cube in the size of the output LUT (32x32x32 atm). Take each color in the source image and create a vector to the color in the output image. Average all these vectors and place them in the RGB cube. Export RGB cube as LUT. Profit.
As you can see, the algorithm explains both the downsides and upsides. If I manage to do some interpolation (or maybe extrapolation is a better word), it would probably slow it down quite a bit, but maybe it could be made optional and controlled somehow, aka you could choose how much interpolation is to be done. We'll see.
Important note: Most of the options in the tool don't actually do anything, so don't bother with them. They are stuff I wanted to implement or might implement some day. The only option that really does anything currently is the "Aggregation Variable" being set to Absolute or Vector. Absolute is the old algorithm I had for months but it wasn't precise enough. Instead of averaging vectors, it was averaging absolute values, which gave decent results but in some situations the results were disappointing. The Vector algorithm is default now and solves that issue.
Edit: Since this is open source, feel free to contribute if you want to ofc.

Barry Lyndon - German Version |

An acquaintance has asked me to check the possibility of restoration of Stanley Kubrick's Barry Lyndon. As with all of Kubrick's movies prior to Full Metal Jacket, the German theatrical version featured fully localized titles and intertitles.
The DVD/BluRay only contains the original English credits / intertitles. Therefore, I decided to give it an evaluation, what can be done.

Fixing A GOOFY MOVIE (1995) |

This started really simple: I just wanted to take the audio of the 1996 US CLV LaserDisc, which is digital 44.1 kHz PCM, and sync it to either the 2001 UK DVD (which is of course PAL) or the 2019 US/CA Blu-ray or both. But then I found that both had their own problems.
The 2001 UK DVD is the original theatrical cut of the film. Being an old PAL DVD, it's encoded as a 4:3 frame with a resolution of 720 x 576 (pixel aspect ratio 59:54 so it ends up displayed at 768 x 576). It's also the only widescreen home video release of it (i.e. in the original theatrical aspect ratio of 1.85:1 or thereabouts) since the 1996 LD, or at least it was until the Blu-ray came along last year, because the US DVD was pan & scan (presumably heavily cropped at the sides). It is also unfortunately an old MPEG-2 DVD at a low enough bitrate to fit on a single-layer 4.7 GB disc, same as the US double-sided THE EXORCIST DVD I upscaled recently for Halloween. Apart from that, it's very grainy because it's from a film source, and the audio is 192 kbps Dolby AC-3, but it is at least the original film for the most part.
The 2019 US Blu-ray Disc, on the other hand, looks significantly better and actually pretty damn good overall, especially for a Disney Blu-ray (if it's not already clear, I have been hurt before... see Beauty and the Beast, Cinderella, etc.) But there are two main issues with it. First off, the audio is once again lossy Dolby AC-3, although at least this time it has a respectable enough bitrate of 320 kbps and it actually sounds pretty decent from what I can tell. But secondly, and much more annoyingly from my perspective, Disney's been up to its old meddling antics again with this disc and they've redrawn some of the animation specifically for the purposes of censorship, as far as I can ascertain. Most of these moments seem to pertain to them trying to erase some fairly subtle and fairly 90s humour, which must have been determined to be A Bit Too Rude for 2019:
Of the above four now-censored scenes, the only one that even slightly raises an eyebrow for me is that second one, wherein the protagonist Max reacts with intense excitement to having a positive interaction with the girl he likes and then proceeds to dance around the room with a seemingly amused school secretary... but in the theatrical/LD/DVD version, as you can see from the above, he's not particularly self-aware of where he's putting his hands. I can definitely see that being interpreted as problematic, if noticed at all, although honestly it's only ever for maybe 1-3 frames at a time that you'd see the offending hand positioning so it's not exactly something that jumps out at you unless you're navigating frame by frame or specifically looking for it. The others are innocuous and in some cases fairly hilarious imo, particularly that first one (which would only conceivably be an issue if it was more than a few frames of contact and/or wasn't in what is very clearly coded as a clichéd dream sequence in the mind of a pubescent teenage boy). But that's not even really the point: the point is that it's been changed and is now no longer the original cut of the film for that reason. And as you'll know from my constant banging on about it with STAR WARS and THE EXORCIST and all those other films that have been messed with, I'm not OK with that.
To make matters worse, even after I then decided to basically just stick with watching the DVD in general (with my custom LD audio), I then discovered one really huge sync error on the DVD, in the video I intended to keep rather than the audio I intended to discard: the title sequence at the very start has the text "WALT DISNEY PICTURES presents" appear in sync with a flourish in the music before fading out for the next piece of text to take its place, except that on the DVD, it doesn't do either of those things. Instead, it appears 16 frames (2/3 of a second) too late, putting it very noticeably out of sync with the music, and abruptly pops out of existence instead of fading out as it should. So even the already low quality DVD video isn't good to go without further edits.
So now, as with THE EXORCIST, this has turned into a video-and-audio project instead of a straightforward audio resync.
-
Firstly, I've already resynced the LD audio to both the Blu-ray and the DVD (although in the case of the DVD, I deliberately did NOT attempt to resync the audio to fall in sync with the "WALT DISNEY presents" text because this would sound awful and it wasn't "fixed" on the DVD audio anyway), so the initial goal's already met. But I want to get the DVD looking at least basically watchable, even if I can't necessarily make it look great.
The easy bit was arguably fixing the sync issue with that mis-timed text, so I did that quickly by excising some frames from before it (which clearly weren't meant to be there), looping some frames of blue background afterwards, and creating a dissolve to fade the text into the looped background frames in an approximation of the original fade out from the theatrical/LD/BD cut. Easy peasy:
pw =
But getting the noisy 2001 DVD encode to look decent in 720p is a bit trickier. I could theoretically just leave it as 720 x 576, but I'd have to re-encode it anyway regardless because of the edits to the video, and I'd also have to either use non-square storage ratio (e.g. by setting "-sar 59:54" in the encoder) or rescale it anyway to get square pixels at 768 x 576, and I figure if I'm going to be doing those things then the quality is probably going to suffer *more* than if I just go ahead and upscale it (because at least if I up-and-then-downscale I can do things like antialiasing to try to improve it at least a tiny bit).
I'm messing about with different upscaling methods like I did on THE EXORCIST and I think I'm probably going to just keep using the same basic methodology that I used on that one for this as well. I tested out some specialised upscaling filters/scripts like SuperRes and so forth but they all resulted in an overly sharp image that just accentuated the already heavy grain, video noise, edge enhancement ringing/haloing and video compression artefacts that were in the original DVD encode. The way I did THE EXORCIST looked... well, fine, but certainly not mindblowing. It's softer by design than most of the rescaling filters people seem to commonly recommend, because I honestly feel like it looks better that way due to all the noise/artefacts in the original source. Still, it's highly subjective, and often the differences between one method and another are so minute that I can't really decide definitively which looks best. What I did for THE EXORCIST was a bicubic upscale (4x) followed by a bilinear downscale to the target resolution; I did that initially on this as well, but I figured maybe it's also worth giving a spline method a bash to see how it looks. It is indeed sharper, which is why I didn't use it before, but I don't know if it necessarily looks bad and in some ways the little bit of extra sharpness arguably helps with the hard outlines of the animation.
Here's how it looks after the "Exorcist method" of bicubic upscale then bilinear downscale. Obviously this has also been compressed by Vimeo so it will probably look a bit worse than it would if you were looking at an x264 encode directly on my machine (same pw again):
Finally, a couple of particularly noisy/artefacty comparisons between bicubic-then-bilinear and bicubic-then-spline36 scaling so you can see how small a difference it is, but nonetheless that the spline scaler does give a sharper image (for better or worse):

PAL 4:3 DVD's |

Not sure if this has come up before but I've a question about playing PAL 4:3 DVD's on a widescreen TV.
Been watching a few old UK TV series recently and noticed my TV displays the image in 720x576 (1:25) rather than (1:33). This is clearly because I have the TV set to 'Full Pixel' mode but none of the other screen options are able to force 4:3
My question is, should PAL DVD's look this way or are the effectively being vertically stretched by the widescreen TV?

I'm as impressed as I am confused. What the hell could the source for this possibly have been if not film? (He says in the description it's a "video transfer"!)
It got a LaserDisc release, but as far as I can tell only one with French subtitles; I suppose it's perfectly conceivable that those could've been removed, given the quality of the upscale, noise removal, and colour correction job. But holy crap, how?!
This is pretty much a load of nonsense whereby Michael has some fun getting Stan Winston to go nuts with makeup effects and the like, but it's exactly the curiosity that I think is important to preserve. I wish I knew what the hell this guy did to achieve results like this.
