4K restoration from original technicolor negatives

UK MoC Blu-ray uses the same restoration as Criterion but has more natural contrast and more organic grains see caps

MoC Blu-ray has the exactly same audio as Criterion Blu-ray

US Criterion 4K Blu-ray > UK MoC 4K Blu-ray > Australia Imprint > US Kino Lorber better encoding

The MoC, Criterion and Imprint UHDs were encoded by FiM making all 3 very close. The higher bitrate helped in deciding and some luck; however Criterion is the most consistent one of all 3. Imprint has some scenes with more splotchy grain while MoC is quite close to Criterion but has some more blocking in dark scenes (e.g.: comp #27). With Criterion’s superior audio, it ensures complete consistency.

From cbc: "I'm personally quite fond of the restored track on Eureka's 4K Blu-ray. It does have spots with objectively worse fidelity, but for the most part, it sounds a lot more natural and less shrill, particularly dialogue. It seems to be a new mixdown of stems. Technically a remix, so not everyone's cup of tea, but it's not revisionist like most new movie mixes tend to be"

Both Imprint (included in their set) and Capelight (on its own/individually) offer remastered BDs. All other BDs, including the one included in The Complete Kubrick, are sourced from the same older master from around 2010.

Arrow 4K Blu-ray  used what was also originally screened theatrically: The Perspecta Stereo 3.0 and a mono option. The Perspecta track sounds best with better dynamic range and was set as default with the mono as optional. The previous releases stereo were downmixes of a now lost original 4-track, and it sounds very thin as a result. See comparison
