Perfect Days (2023)

Arrow has a different grade and a better encode than the Shout! Factory, though the difference in either is not major. Imprint release, which leaves Shout! Factory's master and subtitles as is, is encoded by FiM. https://forum.blu-ray.com/showpost.php?p=24473097&postcount=56

Original mix: Shout! Factory 4K Blu-ray (similar to Criterion LaserDisc, but less distorted)

Alternate mix: Scanbox Nordic PAL DVD

Surround remix: HK Video France 4K Blu-ray (5.0)

Arrow used the alternate mix, but with extra filtering and lowered dynamic range. The alternate mix has much better fidelity.

Imprint presumably used the Shout! Factory original mix and left it as is, though no official confirmation.

Arrow has a much better translation.

Arrow LE has the Taiwan Extended Cut which will not be present on the standard edition. However, Imprint is FiM and has its own archival extras not present on the Arrow.

DE Koch Media is presented in the correct 25fps and is likely better compressed than UK Dogwoof (29 vs 14 Mbps), but it doesn’t have English subtitles.

US Drafthouse is in 24fps for Region A compatibility, and is encoded at around 30 Mbps.

(Although bitrate does not solely determine the quality of the encode, the difference is large enough here and there are no publicly available caps.)

No info on the JP VAP Blu-ray.

DE Koch Media and US Drafthouse feature a lossless 5.1 track. Dogwoof offers only AC-3.

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.

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.
