Youtube HD Streaming apparently from Library of Congress but not officially. This is a significant improvement over previous public domain sources though, so it's enough reason to believe it's a newer scan

US Shout! Factory or UK Eureka Blu-ray likely very similar from other comparison in the same boxset see DVDBeaver

Imprint Blu-ray not only has the best encoding, but also has the "correct" aspect ratio compared to ClassicFlix which is horizontally stretched or Eagle Pictures which is squished see DVDBeaver caps

4K restoration from Original Camera Negative

Indicator Blu-ray has better encoding than Criterion Blu-ray, both 4K restoration, see DVDBeaver caps

No caps on France Elephant Films Blu-ray

Fox Blu-ray has both Todd-AO and Cinemascope on each Blu-ray disc. The Todd-AO is a 30 fps restoration from 65mm IP scanned at 8K

Germany Plaion Blu-ray > UK Arrow > France Carlotta All three use the same source but all very minimal difference.

There is no comparison with Criterion Blu-ray

The Arrow Video Blu-ray is the best iteration so far coming from a new restoration complete with great supplements and package. The original limited edition version included a second disc with the alternate 2.0:1 framed version. The primary disc is 1.85:1. Older releases pre-2008 were all in Academy ratio. 1.85 is the best compromise ratio for the visuals. As good as this release is, the master is showing its age and sadly has a number of frozen grain artifacts.

Same master, but less bitrate starved.

The encode on the BD is preferable to the UHD. Same master, but less bitrate starved: https://x.com/SadHillDevan/status/1530057783885721607?s=20 and see caps

Germany Plaion Media Blu-ray is marginally better than Kino Lorber which suffers a little dark crush: https://slow.pics/c/BME05Jlw
