21 Jump Street (2012)

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.

4K is defective with color space issues and poor encoding, UHD replacement disc is also defective with worse encode. The UHD has visible artifacts from the bad encoding. The HDR is overdone and the Paramount 4K master has grain management.
The new Kino Blu-ray has none of the UHD's problems and is superior to the UHD in every way though it still uses the same Paramount master.

The Lionsgate BD and Paramount BD share the same lackluster HD master with DNR and image distortion. The Lionsgate is much better encoded but has a 7.1 remix which messed up the original mix design by lessening all the great Foley work in favor of the score. The Paramount BD had a 5.1 lossless version of the original mix but it's a new version where the bass has been tamed so the track has lost its punch. The Kino Lorber UHD and Blu-ray recycle this same lesser 5.1 mastering. The original mix can still be heard on LD and DVD. The 2.0 stereo on the Kino is matrixed but also does not sound as good as the 2.0 matrix audio on DVD or LD.
Kino has a replacement program for the defective UHD to fix the color space issue. The new disc is not marked, has a worse encode AND DOES NOT FIX THE COLOR SPACE! Thus it is a worse defective disc version of the original defective disc.
The Billy Zane interview on the Kino BD has technical issues in the editing and clip quality used.

Both 88 Films and Germany Capelight are superior to the Shout! Factory in HDR10 but their FEL layer may even things out. Objectively, the Capelight looks best as they avoided the chroma blocking that’s visible in 88’s disc but they in turn included an Atmos mix. I have the Shout! Factory, love how it looks and the 4K transfer is spectacular. https://slow.pics/c/vPmFQSAH
