DNR

US OOP Twilight Time Blu-ray > UK Paramount Blu-ray or US Inspired Blu-ray

The UK Blu-ray not only have some DNR applied, it's also squeezed and cropped: see comparison

The color contrast from Twilight Time is however possibly suffering the Quicktime Gamma Bug, but that's an easier issue to fix than DNR or cropped images.

Less bitrate but MoC uses too much DNR

(Britain release only has 5.1)

The Paramount 4K "restoration" is a desecration. It has completely revisionist color timing, harsh HDR, treatment of stock footage, bad encoding, selective DNR and grain management so bad that the entire screen frequently freezes up with only characters moving around in grain soup. It is so bad that the film's restorer Robert Harris publicly washed his hands of it saying essentially the 2007 restoration (with Willis and Coppola supervising) is how the film was intended and made. This is Paramount's modern version done their way. The new 1080p SDR Blu-rays in print are the crap 4K desecration master with the same problems still there just harder to spot and with crap encodes.
The mono option is an unnecessarily processed version of the lossy mono from the 2008 Blu-ray. The 2008 Blu-ray of the 2007 Coppola Restoration while an imperfect outdated disc is LIGHT YEARS better than this 4K desecration. The only truly major issue is that it is very slightly redder than the 2007 finished master as seen on DCPs. The lossy mono on the 2008 Blu-ray is the best version of the original mix known to exist as it is better than the late 80's mastering for VHS and LaserDisc.

Shout! Factory 4K Blu-ray > BFI 4K Blu-ray, see caps https://slow.pics/c/nPcxCNW4

Some find BFI better but with more DNR and AI upscaling like their horrible 1979 Nosferatu 4K Blu-ray, and Shout! Factory has more over-exposed grading https://slow.pics/c/WQKmBTLJ

2000 R2 Stonevision DVD vs Shout! Factory 4K Blu-ray?

Part II overall fares better than the first film but it has all the same problems. Randomly some shots are the worst in the trilogy looks mushy and manipulated to death.

Blu-ray better than Capelight Germany 4K Blu-ray, heavy DNR on the 4K Blu-ray

While has some mild DNR in a few scenes, the old Universal Blu-ray was an even older VHS master with DNR, so it's still a significant upgrade

Kino Lorber 4K Blu-ray's source is provided by Paramount has had DNR applied which affects the inherently soft looking film pretty strongly for at least a third of the running time

Cohen Blu-ray is the best with the least amount of DNR or sharpening among Germany StudioCanal, UK MoC and France Gaumont. Even though Cohen doesn't have the best encoding, it's definitely the most superior release. See caps-a-holics caps

If not, the 4K Blu-rays are generally considered an improvement over the 2011 Blu-rays. (although both restorations are DNR'ed and have issues).

Shout! Factory 4K Blu-ray has DNR applied and encoding could be better. Possible issues in Dolby Vision

Great source, poorly encoded but it does look significantly better than the Blu-Rays.

Better than 2022 Shout! Factory 4K Blu-ray due to poor encode and heavy DNR (review)

Puppetoon Productions Blu-ray link is 4K scan of Original Camera Negative while has some degree of DNR is still a significant upgrade over previous release

Paramount 4K Blu-ray has heavy DNR in many scenes

Paramount 4K Blu-ray has DNR applied but it is still much better than the bad Blu-ray

SC caps. Great-looking 4K master except for DNR'd higher-gen shots such as the opening sequence. StudioCanal resolves finer detail but has encoding issues in highlights, the non-Original Camera Negative shots and traces of chroma noise. Sony used a low-pass filter which makes the film look less sharp and finely detailed but the encode is more consistent.

StudioCanal and Universal Blu-ray have DNR. 4K master also exists, unreleased

Bandai 4K Blu-ray? vs 2008 Japan Bandai Blu-ray (BCXA-0085): same video but includes Bandai English dub and original mix

Has English subtitles, better than 2015 Maiden Blu-ray which lacks the original mix

But completely DNR'd.

For grain, most release starting from 2007 Japan Bandai Blu-ray (BCXA-0003) are ok.

The 3D Blu-ray has most of the grain kept

The Disney 4K Blu-ray, while improving slightly on resolution, has significant DNR applied; see Blu-ray
