4K Blu-ray

Japan DVD has more extras compared to the HD/UHD releases

Both cuts are excellent in 4K. See caps

Director's cut: 2007 WB Blu-ray; Arrow is a lossy transcode with dynamics compression.
2007 BD's AC-3 track with dynamic range compression enabled is nearly identical to Arrow's, see comparison

Theatrical cut is fine.

2.1 Cut received a 4K remaster for a cinema release. No announced home video release yet.

(Unrated cut on Blu-ray)

Paramount/Plaion Spain/Italy 4K Blu-ray has better encoding than the US 4K Blu-ray.

The EUR 4K has missing dialog.

> France Metropolitian 4K Blu-ray (slightly better encoding on the Sony)

Commentaries for the extended cut are only found on the Germany Constantin Film Blu-ray

4K remaster is cropped 2.35:1 from the original 2.55:1 presentation, and has significantly different color grading, as is the case with most WKW supervised restorations. Due to DNR the detail is sometimes lacklustre compared to the old master. CGI scenes appear to be rerendered. A sepia tinted scene was altered to be fully black and white.

Caps: Criterion US BD vs Cannes HD-DVD, HD-DVD vs KR BD vs DVDs vs US BD

The remixed track has different front panning and little LFE use compared to the original.

HD-DVD is by far the best option for the original track, as DVDs and Korean BD suffer from noise gating, limiting and duplicated surrounds. Remixed tracks are all similar, but French disc has slightly better dynamics, particularly on the LFE channel.

The 2006 HD-DVD is a promotional release made in only 100 copies, handed out to VIPs at Cannes Film Festival. See this blog post for details. The same master can be found on KR BD, though it suffers from interlacing, blended frames and a gamma bug, as well as older DVD releases.

Disney 4K Blu-ray has the original DTS-ES 6.1 mix in DTS-HD MA 6.1. Inferior Dolby Atmos remix is set to default.

Paramount 4K Blu-ray has the original colour grade
