It's not a format, it's a certification.  You can have THX together with DD, DTS, PCM, etc.

Hi Kahon!

OK, but is it a certification for audio or video or both?

by the way, i'm just curious: can you name some titles that are available in DTS format and also THX certified star wars episodes I and II are thx certified but are not available in in DTS format, right?

thanks!

Bro,

One title that comes to mind is Planet of the Apes Special Edition R1. Not only does it have a DTS track, it is also THX certified.

What's great about it is that it has some THX setup tests in the Specail Features section !! I've tried it and it does work.

If you read their website carefully, THX is for video.  It was not intended to certtify audio-only sources, but video on VHS, LD and DVD.

It also certifies theaters and equipment.

thanks kahon.

you're right, i should visit their website. also checked out my X-Men disc and noticed that apart from a 5.1 channel audio tester, it had a "video test" menu too.

what is THX?  how is it comparable to DD and DTS?

i noticed that star wars and most disney-animated movies carry THX and not DTS.

please merge na lang with existing threads.  thanks.

Boss THX is not like DD and Dts but it is a certification of audio and video standard for any software or hardwares. It is an "enhancement" to a system. When u see a Laserdisc or DVD whether in DD or Dts decoding  with thx logo, expect a great sound and picture, but cosider also a THX certified components.

I guess a movie with THX certifcation is only surely better than a version of the SAME movie without the certification. but when comparing different titles, THX is not necessarily the top of the line in its lonesome. while for sure, THX does maintain a standard of quality in determining certification, THX is not at all the Holy Grail of DVD productions.

of course, not all movies / DVDs have been reviewed for THX certification. if at all, only a small portion of all DVD releases have been reviewed for this purpose. and if there are any, they don't exactly advertise which DVDs failed THX certification.

likewise, many DVD manufacturers who don't employ the assistance of THX in the production of DVDs do excel and produce DVDs at par or even better than "THX quality". New Line, for instance, does not seek THX certification but produces top-notch DVDs, like the LOTR series, for example. the list here (http://www.thx.com/mod/products/dvdFind.html) (click "entire list") clearly shows THX's "allegiance" with Disney/Buena Vista and Fox, among others.

the bottom line probably is to not base your purchases solely on THX certification. THX is not the ISO of the DVD industry.  ;)

Title: Re:THX
Post by: krets pulpol on Feb 12, 2004 at 12:06 PM
well said! thx is just a certification that a dvd or other components have met their standards.  they have their own criteria for passing their standards and not only in audio but video as well.  it doesn't stop there, they concentrate on movie theaters and custom installations in certain homes, they evaluate the acoustics of the room, proper projection of movies from lighting to hues etc.

for dvds, some of them have exceeded the thx standards even if the dvd package says it's not certified. but you can ask them to certify certain dvd titles on their website.

dts, dolby and thx do not compete with each other, dolby and thx even tied a partnership to develop dolby digital ex (an extended surround channel at the back) - surround center

for history of thx, i can post it sometime if i can get my document in my pc.

THX certified equipment are expensive because they have to pay Lucas for the THX royalties.  THX is a certification process to tell the world that the product  conforms to THX standards.  A wee bit better than an ISO certication. 

But if you read many DVD reviews on the net, you'd be surprised that some reviews of THX certified DVDs don't pass at all and even questions how THX came to certify so and so lousy DVDs.  While there are laudable technical standards behind it, some on the net have opined that the THX logo has evolved into a marketing tool to better attract buyers.

For me, I don't bother at all with THX logos in DVDs. I just read technical reviews of the DVD I like to learn how a DVD release perform.  With regards amps and receivers, if I recall right, the THX minimum standard is 100wpc for power.  Hence,  there are many sub-100wpc amps that don't carry the THX logo like many HK models.  But I can assure you they sound incrementally better than some 100wpc recievers that do.  It seems to me that the THX certification is no guarantee of better sound quality.  Just an indication that the product conforms to some set of standards so they can work with other gears with the same THX certification in synergy.  That means one should use a THX-certified DVD player to connect to a THX-certified receiver to drive THX-certified speakers in order to max the synergy or to properly claim you are benefiting from a THX-certified set-up. 

Actually, to really max out the synergy, you should invite Lucas engineers, all expenses paid by you, to also certify your video set-up,  room accoustics and speaker placement as THX compliant.  ;D  The same way they certify a theater as a THX theater using only THX-certified lighting, screen, accoustics, video and audio gears.  Then you can probably max the use of THX-certified DVDs.  ;D

Having bought ang installed all of it, is it worth the tons of moolah you've invested in it? In my personal experience, when Louie's THX opened and have watched LOTR there for curiosity's sake, after watching, have to ask myself the question: "What was the big deal all about THX?"  I just noticed that the sound had a higher volume than usual and sometimes irritating and too loud. :-\

That's just me though.

hahahaha agree  ;D  the only advantage of theatres is the big screen hehe

nirv, i think when you watched at louie's thx, it has a different management.  before, louie's thx is way better than today's cinemas. 

and by the way, thx is not just being loud.  it's a synergy between your equipment, acoustics of your room, projection of movie with correct contrasts and hues, better blacks, correct balance of surrounds etc.  i think when thx approved most cinemas here they were new.  maintenance is a key factor in keeping the standards as it is.

for dvds, it doesn't have to be certified by thx for better sound and visual quality.  some releases are far better than thx certified dvds.   ;D  sira speakers mo hahaha

Post by: nerveblocker on Jul 30, 2004 at 01:23 PM
jerix-  Yup!  And you don't have to spend that much moolah to watch it.  Guess there is a psychological effect that if you are watching in a lazy boy or in bed, the sound seems to be better...it lulls you to sleep!  Haha!

nope not necessarily, they may still have the same equipment i'm not sure but they could have maintained the state of cinemas there.  i guess the only way is to renovate the cinemas and recalibrate the equipment incl. projections.  and before, some movies were ahead the local screenings just like the advanced screenings in ayala cinemas.  and by the way, tickets were for members only, so ask if they have extra tickets before hehe

Has anyone noticed any difference in PQ or SQ of R1 THX certified DVDs and local R3 DVDs with no THX?
An example would be The Incredibles and Tarzan, The R1 has THX while the R3 does not.

Post by: Quitacet on Jun 07, 2006 at 04:37 PM
As per sir firewired's previous posts (if I remember it correctly) the R3 and R1 use the same master for DVDs. The R1 has no problem displaying it's being THX certified because they paid royalty to THX or something to that effect.

The R3 on the otherhand, though it used the same master, don't display "THX Certified" and has no THX Optimizer due to region limitation of the certification. And maybe to lower the cost of the R3 releases.

This might mean that the R3 Tarzan, as posted by matzter, is already THX Certified because it used the same master as the R1?

R3 minus the THX logo & optimizer?

Parang ganun na nga, if I remember sir firewired's post (pasensya na wala ako oras maghanap sa threads nung post niya), there's no difference really between the R3 and R1 Disney DVDs (during that time Incredibles R1 and R3 pa ang issue because of the VIVA Sale when people are looking for the R1 when the R3 are all over the place).

Guys,

eto na. nakita ko na yung post ni sir firewired sa Astrovision Makati starts Christmas Early thread, and he syas:

"Re-posting from another thread:

The R3 uses the same THX certified English 5.1 track and video transfer that's on the R1. Either Disney didn't want to pay the extra fee for having the logo and Optimizer app in the R3 release or the set wasn't eligible by default because the Asian language dubs were not submitted to THX for evaluation."
