Plaion German 4K Blu-ray

Plaion German 4K Blu-ray > US Kino Lorber see comparison and caps

Kino Lorber has an exceedingly poor encode, only slightly improved by the DV layer.

Original matrixed Dolby Stereo: Universal US Blu-ray
Dolby Atmos remix: Plaion DE 4K Blu-ray

Universal's BD uses the same transfer as the old LaserDisc and sounds a bit better than Plaion's, which has worse dynamics.

Plaion's Atmos remix is tastefully done and preserves the original mix's characteristics, the 5.1 track on Kino's release is overly aggressive and unbalanced.

2015 Lionsgate Blu-ray 

• 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.

• Original Kodak/ORC CDS mix:  Japan Pioneer DVD in DTS/ac3 5.1

• Original Dolby Stereo SR: USA Widescreen LaserDisc and others.
