AC3 Mixes of Laserdiscs do Not Contain True Theatrical Masterings

[Sambarker04]

I have the US LaserDisc of Bean The Movie and the LD AC3 mix is way different than the R1 DVD mix. Firstly, there was heavy compression throughout and the rear channels have been screwed up. On the left rear channel, it was either the mono rear or one of the rear channels, and on the right rear channel, it was a duplicate of the LFE channel. The LD mix also includes the final seconds of the post-credits scene where we hear Mr. Bean’s footsteps fading out that was cut on the DVD mix. I haven’t analysed the two yet, so I don’t know if this LD mix was done to be near-field or not.

The same goes for other AC3 5.1 laserdisc film mixes, which have serious limitations on their dynamic range and gain levels. I analyzed most of them.

An incredible claim. There are so many laserdiscs with AC-3 (over 1100 according to the lddb).

Could you share with us some more examples?

This only holds true if you have compared to the CDS track decoded from a print.

There's no getting around this. If you're not directly comparing it against the actual theatrical audio your point is pure speculation.
