What I might have meant is from John's quote movies with THX on the label are mixed bright and harsh to get the sound thru the perfed screens. To my knowledge RE-EQ is only a home enhancement, and not in the theaters. Am I wrong?
Movies in general are mixed bright for theatrical release, this doesn't have anything to do with THX.
THX certification for home video software (laserdisc, VHS, DVD) is simply a quality assurance program that tries to monitor and control the mastering process so that the resulting transfer comes as close as possible to the original master that was submitted. Nothing more. It doesn't have anything to do with how the films were "seen in the theatre", which has never been a requirement of the THX mastering process. If it had been a requirement, you couldn't have direct-to-video titles ('Armitage 3'
, 'Queen: We Will Rock You'
, the 'Tenchi Muyo'
series, etc) that were THX certified; after all, how are you supposed have the mix be identical to that used in the theater if the film was never released theatrically?
Even if a movie soundtrack has been changed from the theatrical version and re-mixed for home use, as was done with the movie 'From Hell'
, it can still be submitted for THX certification. All THX will do is make sure that the resulting DVD comes as close as possible to the audio/video master that was submitted. If the theatrical treble boost is in the master tape, it will be on the DVD. If it has been equalized out, then it won't be on the DVD. If you submit a master tape that has the left front and left surround channels combined, as happened with Disney's animated 'Tarzan'
, then the resulting THX certified DVD will be a perfect match and have the same exact problem. (The problem was fixed on the later Special Edition.) They match input to output; they don't tell studios or film makers how to mix their soundtracks.
No quality assurance program has ever been 100% perfect, and THX won't be the first. Still, THX titles have consistently looked and sounded good; an impressive track record for their software certification program. Also keep in mind that there is nothing to stop non-THX titles from having higher quality than THX standards. Same with pre-pros and receivers: while the THX ones meet certain quality standards, there's nothing to stop manufacturers from producing even better products. Remember, it's A
standard, not THE
While there are a few things about some of the THX cerification programs that I consider useless (like approving DVD players plagued with the chroma bug), I can't see any reason for bashing everything
associated with them. There are genuine things to criticize about THX; no need to make stuff up that's not true (e.g., they boost the treble, they drop requirements to gain the support of studios, their DVDs will "rip your head off", etc).
If you want an explanation of the THX software certification process, you can check out their brief articles on digital services
. It will give you an idea of what's involved.
