Criterion

Included as extras in the Criterion 8½ Blu-ray. Looks like SD source, and in a very rough quality.

Criterion Blu-ray source features proper gamma and black levels with a superior contrast. MoC Blu-ray source features improper gamma and black levels and too bright a contrast, making the picture appear washed out. See caps

Caveat:  MoC Blu-ray has slightly better encoding than Criterion

Criterion Blu-ray is slightly better than MoC Blu-ray: while both are from a 4K restoration approved by director, MoC is more sharpened but gamma is flatter see caps

Paramount DVD and potentially Paramount LaserDisc see blah-ray

Criterion and MoC Blu-ray has the same audio, and additional (destructive) hiss reduction was applied, and one segment was made significantly louder.

Also, every home video release except the 1982 Paramount VHS cassette replaces Wild Man Fischer's 'Merry-Go-Round' in the roller derby scene with a version of 'Sweet Georgia Brown' by Brother Bones. Two very different songs, and one must assume that the tone of the scene has changed considerably

Criterion Boxset Blu-ray or UK BFI Blu-ray no comparison available

Criterion Blu-ray is significantly better than Universal Blu-ray see caps

Criterion Blu-ray is a newer 4K restoration, and much better than older Arrow Blu-ray and the Arrow reissue is slightly more cut-off than the Criterion Blu-ray too

Criterion Blu-ray is a newer 4K scan and is an improvement over older Sony Blu-ray see caps

While Criterion Blu-ray is 24bit over Sony 16bit, they sound the same according to Blay-ray

Criterion Blu-ray is a newer 4K restoration

Criterion Blu-ray generally has more noise reduction than the DVDs and the other two blu-rays, but its EQ more closely matches the LaserDisc - though dialogue still sounds a bit comparatively hollow. See blah-ray review

Criterion Blu-ray new restored 4K digital transfer approved by Charles Burnett

HD restoration supervised by Peter Davis and Richard Pearce
