DNR

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. Part III fares best of the three and these issues are at their most minimal-but they're still there. The new Coda version is given prominence with lesser encodes for the other two versions. The original mix was remixed into 5.1 decades ago and we have yet another version of this instead of the original Dolby Stereo SR as heard on the LaserDisc release.
The 2008 Blu-ray of the 2007 restoration, while an imperfect outdated disc, is LIGHT YEARS better than this 4K desecration.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.

Despite being restored alongside the Coppola Restorations of The Godfather: Parts I and II, the Part III restoration is not officially labelled a Coppola Restoration.

• 2015 Lionsgate Blu-ray (but it's missing the extra scenes in the Ultimate Edition)

• 2017 StudioCanal 4K Blu-ray and subsequent 4K Blu-rays are notorius for being heavily denoised and smoothened. Alternatively, 35mm scans for the theatrical cut is also available.

• For the Ultimate Edition with the T-1000 searching John's room and the happy future ending, the 2009 Skynet Blu-ray, which is the older pre-2017 transfer, but has DNR.

Differences of mixes on various releases: see thread and more info here.

2017 Blu-ray (which has the DNRed transfer), the 2009 Skynet Edition Blu-ray, and the 2000 Ultimate Edition DVD have exclusive extras. The 2003 Extreme Edition DVD has some exclusive easter eggs.

Lionsgate and StudioCanal 4K Blu-ray share the same video master: both have considerable improvement over the old awful Blu-ray but marred by teal grading and DNR. Lionsgate is additionally better compressed than StudioCanal.

Lionsgate 4K Blu-ray has the original theatrical 2.0 track, sourced from LaserDisc (absent on StudioCanal 4K Blu-ray), but the 5.1 track has issues which are not present on their new Blu-ray (LFE channel is missing, and instead it's the back left surround duplicated)

AU Umbrella 4K Blu-ray > US Kino Lorber 4K Blu-ray 

The US/Theatrical Cut on the Kino Lorber 4K Blu-ray is AI upscaled and has DNR, along with Kino Lorber's usual poor compression.

Director's Cut uses a proper transfer but suffers from terrible compression, even by Kino standards.

The Umbrella with its FiM encode looks blurrier due to a slight low-pass filter, but is still far better than Kino.

AU Umbrella 4K Blu-ray and US Kino Lorber 4K Blu-ray are the same.

The 5.1 track is a direct port of the lossy NTSC DVD track.

Avoid the Germany Hanselab 4K Blu-ray, as it's riddled with oversaturated colors, poor encoding, AI upscaling, and DNR. The included Blu-ray is also DNRed.

Italy Eagle Pictures 4K Blu-ray has better compression than StudioCanal 4K Blu-ray, green-ish SC master that restores some blown-out highlights compared to the Sony master, but bad HDR10 compression (details). The 2023 Sony 4K Blu-ray steelbook has different grading and Dolby Vision that some may prefer, good encoding, but heavy DNR for about 15% of the runtime.

Pick your poison between Eagle Pictures or Sony.

2025 Universal 4K Trilogy Steelbook / 2026 standalone is better than previous disappointing 2022 4K Blu-ray (excessive DNR). Not a whole new scan but the grain has been left mostly intact.

Cinema DTS is OG 5.1 mix.

Otherwise: 2022 4K Blu-ray’s DTS:X remix is more faithful than 2026’s Atmos remix.

3D Blu-ray’s 7.1 remix has reportedly less distortion than the OG 5.1 mix, and is presumably more faithful than the DTS:X remix.

Fan preservation is likely better quality.

The 2011 Lionsgate Blu-ray is incredibly poor for every Original Trilogy film; older processed older DVD-era masters with heavy use of DNR, sharpening and edge enhancement with a really dull color grade. The 4K Blu-ray is miles better. The DTS-HD 5.1 across all three films appears to be the same on both the Blu-ray and 4K Blu-ray, and they appear to be the untouched theatrical 5.1 mixes. 

The Uncut version has more violence: https://www.movie-censorship.com/report.php?ID=256325

Turbine 4K Blu-ray has the better encode. Paramount 4K Blu-ray is disappointing review. But both have DNR?

Criterion has heavy DNR

Other releases have horrendous DNR

2012 Criterion Blu-ray is the most accurate

4K Blu-ray unrecommended because of controversial colours, no HDR, minimal resolution uptick, and DNR master

The 4K Blu-ray 5.1 adds additional foley and effects.

Caveat: mostly great video but the 4K Blu-rays have had additional DNR applied in some scenes on top of the DNR that had been applied in post-production and was already present on the DVDs & Blu-rays

The 2020 Blu-ray (the one without the green tint) may be better than the 4K Blu-ray?

New Line Blu-ray have the original 6.1 mixes

4K Blu-ray set is missing extras from the old Blu-ray/DVD releases

The 2011 Blu-ray notoriously had a green tint, the 2020 one removes it.

The Universal Blu-ray is slightly filtered and DNR'd compared to the HD-DVD, and the Universal 4K Blu-ray, on top of being upscaled, adds additional DNR and is softer than both previous HD releases.

Versions:
- The International version contains a short additional scene (part of the "Farmhouse" extended scene from the special features). See additional detail below.
- The US version does not contain this scene during the film. Director Doug Liman confirms in his audio commentary that the scene was cut from the original US theatrical release "for time".
- "The Explosive Extended Edition" found on some DVD releases is not an alternate cut of the film, simply an access mode that plays "The Bookend Scenes" features via non-seamless branching.

Deck the Halls scene:
The U.S. release is 118:17 while the European/Australian/Japanese releases are 118:36. There is no difference between the two running times from the start, but at 81:21, the U.S. version cuts from a kitchen scene of Marie and Eamon washing dishes, to a scene of Eamon bringing blankets to Jason and Marie. On the European/Australian releases, at the same point, there is a scene of Jason, Marie, Eamon and his children eating dinner while "Deck the Halls" plays in the background. There is no dialogue, the characters just each exchange uncomfortable glances. The scene goes to 81:40, then picks up the same scene of Eamon bringing blankets. This scene is included as an extra ("Farmhouse" extended scene) albeit sans the holiday themed music. Many thanks to Rewind user Mark Bowen for comparing these releases and letting us know the difference.

StudioCanal 4K Blu-ray has poor encode and heavy DNR

Shout! Factory Blu-ray is from original DI master. The film was an early DI and film prints also looked poor. Shout! Factory Blu-ray is representative of original release. StudioCanal 4K Blu-ray has some new VFX work done along with some plates reshot as well as poorly upscaled original VFX work.

Caveat: mostly great video but the 4K Blu-rays have had additional DNR applied in some scenes on top of the DNR that had been applied in post-production and was already present on the DVDs & Blu-rays

The 2020 Blu-ray may be better than the 4K Blu-ray?
