Capelight 4K Blu-ray has better encode than Criterion 4K Blu-ray

Arrow UK /Capelight DE 4K Blu-ray > Kino Lorber US 4K Blu-ray, see caps

Arrow has done additional cleanup work removing nearly all the damage in the transfer. They have massaged the color timing and HDR to try and improve what they could. The Capelight may have better encoding but it does not have these improvements. The Arrow encoding is solid and in motion there are no issues whatsoever. The Kino Lorber release has the damage and other issues plus frequent noise due to the lesser encoding.

Some scenes in the Arrow transfer are better, some are better in the Capelight.

(Arrow is a port of the LaserDisc track, see spectrograms) This track has the best fidelity of any release but does have some channel bleeding baked in. The 2017 2.0 on the Arrow and Shout! Factory Blu-rays was the Dolby Stereo original mix without channel bleeding but that had heavy noise reduction resulting in a very flat and underwhelming presentation. The surround winds up being lessened as well due to the processing. It's a tough choice between the two but the Image LaserDisc audio wins out because it hasn't been messed with and the impact is so unrestrained that no other version hits in the same way.

Capelight and old Arrow Blu-ray included the original stereo mix, but with excessive noise reduction rendering it much less detailed. Kino Lorber only included a painfully defective 2.0 track sourced from somewhere with limited fidelity, volume spikes and screechy high end which frequently ruins the music. The 5.1 remix on most modern release is a processed version that does not sound as good as it once did.

The best and most accurate of the 5.1 mixes is the original version from the 2003 Special Edition DVD in lossy AC3 form.

The best source for the commentaries are from the 2003 Special Edition DVD.

Comparison, caps

Capelight's 5.1 is sourced from the original 6-track. The fidelity is comparable to the 4.0 from the 4-track available on previous BDs.
An alternate 5.1 mix was created for the 1999 MGM DVD / LaserDisc, It boasts better high end detail throughout, but the trade off is reduced bass.

See additional info for more detail.

West Side Story was produced as a 70mm Todd-AO presentation, with an accompanying 6-track audio mix in the following channel configuration: see diagram. 35mm presentations used a 4-track or a mono mixdown instead.

The original 6-track elements were thought to have been lost until they were recovered and restored in 2010. In 1981, for the film's 20th anniversary, a new 6-track mix was created by upmixing the available 4-track elements.

Capelight's release is sourced from original 6-track elements uncovered in 2010, but unfortunately it's not as detailed as it should be, owing to unnecessary noise reduction. It's by no means bad, but it could be better. As the Lc/Rc channels are mixed into into L/C/R, it's also essentially no different to a 4-track fold-down. This isn't exactly an issue as left/right center channels mix down to L/C/R very well, but a better way of handling this would be to use Atmos objects to position those channels where they should be, as Disney did on The Sound of Music.

The 4-track mix was included in a discrete form on MGM's previous BD, it trades blows with Capelight's 6-track-derived 5.1.

Interestingly, the 1999 MGM LaserDisc/DVD release includes a different 5.1 mix, which sounds a bit more detailed than the two other tracks. It's sound signature is on the brighter side, with a slight emphasis on the treble instead of bass like other releases. Although that accounts for some of the perceived detail, even after matching EQ there are spots where Capelight loses out. It's a slight upmix, with split surrounds and LFE. Whether it was derived from 4-track or 6-track elements is not clear, though it matters little, as the end result would have been very similar in either case. There are no booklet notes stating the source used, but it sounds very similar to the matrixed 1992 LD, which was attributed to the 6-track. Still, given that the original elements were thought to have been lost, I would assume that this refers to the 1981 mix.

Previous LaserDisc releases are similar to the discrete 1999 track. All LD releases are missing the intermission music and a brief whistling sequence.

The 7.1 upmix on MGM's Blu-ray offers little of value.

Neither Criterion nor Germany Capelight 4K Blu-ray has good encoding https://slow.pics/c/bWhRoxpi also see Criterion review with disappointing compression per Geoff D

Since posting this, I watched the Capelight in full and the anomalies the caps reveal didn’t bother me in motion. I did look out for issues and can’t really complain. The trickiest scenes are those set in daylight, particularly in the third act, and the Criterion looks terrible here. Unfortunately the caps are just from the first hour but in doing comparisons with the discs, I noticed that Capelight managed to resolve detail more evenly and makes for a more satisfying experience in my mind.

Australia Madman is very similar to Criterion, see caps provided by Joel https://slow.pics/c/9MDRLoOl and https://slow.pics/c/1EVsFQCZ

Arrow Blu-ray has the most extras

Germany Capelight 4K Blu-ray > US Shout! Factory - caps

The 5.1 track sounds very good and is said to be sourced from the original 6-track mix used for 70mm blow-up releases, but there is no conclusive proof of that.

Review for Shout and caps for Capelight

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
