In the best of all worlds, The Patriot* cannot fit on a single layered DVD, so its 240,000 images are split in some fashion between two layers, each of which was designed to hold, on average, 194,000. Therefore, Panic Room* was pressed as a two layered disc, with each layer intended to carry 135 minutes of regularly compressed "entertainment." Again, being simplistic about it, one would use 135 minutes as a maximum.
The quality of a digital video release must initially be based upon the quality of the original transfer from film, which in turn is based upon the availability/selection of a high quality film element. That beautiful transfer can be either destroyed, or come to us as reference quality, by its handling in compression.
Due to the discussion on The HTF, I went to my local Borders and purchased a copy of Panic Room*. After viewing, and sampling the bit rate, there was no doubt in my mind that, albeit in different packaging, Panic Room* IS a SuperBit release.
Sony offered it as a SuperBit ONLY release at a sell though street price of under $20. The only difference between Panic Room* and other SuperBit releases is that it contains some additional track information, which takes up very little real estate.
I was confounded seeing disgruntled comments on The HTF about the release, because it didn't fit into a pre-determined, totally stripped format, which can be predicated by either the film's length or a combination of length, detail and movement within the frames.
I'll repeat. This is a 112 minute film on a double layer disc, capable and designed to hold 270 minutes of compressed information.
One also has to take into consideration that this is a David Fincher film, which in this case means that the frame includes a great deal of darkness, and dimly lit images, which is the single most difficult thing to bring across with high quality on DVD. In Panic Room*, it is more what you DON'T see than what you do, that makes the difference in viewing pleasure based upon a higher overall resolution.
I don't know if the film was even released on VHS, but if it was, then a brief look at a tape will give you some idea of precisely how noisy this film might have looked. It is only because there is no non-SuperBit release that the transfer is calling attention to itself. But going along with Sony's edict for quality transfers AND the fact that this film was only 112 minutes, gave them the ability to do a general release in SuperBit on a single DVD.
Have other companies released films with a high bit rate? Certainly. One such title which easily fits into this mold is the new release from Warner, Divine Secrets of the Ya-Ya Sisterhood*. This 116 minute film also has a high bit rate and one of the most beautiful transfers that I've recently viewed via a new production. It's obvious that a great deal of care went into this release.
As an aside, I went into Ya-Ya blind. I knew very little about it other than it was billed as a women's film. Wrong. It's a people film with superb performances, a many layered story and absolutely beautiful cinematography by John Bailey.
Seemingly, the major need for SuperBit is less with films which run under two hours, and more for films of longer running times, where the digital squeeze to both hold quality while adding features becomes an oxymoron. And this would answer the question of why Panic Room* was available as a SuperBit release at regular prices. The other side of the Panic Room* coin, which should be brought to light however, is that had Sony wished, it could have released the film as a single layer disc -- but did not. They held the quality and went for two layers.Sony has created this as a signature product of high quality, using the trade term "SuperBit." In releasing Panic Room* as such, the studio is simply allowing the audience to know that while this is not being offered as a premium priced product, it fits within the guidelines of a certain quantifiable quality upon which the audience should be able to rely.
The final product is a combination of transfer and compression... and finally authoring. Many titles which COULD be released with a high bit transfer rate are not. What must be understood is that the film elements and transfer quality must both be of high enough quality or the SuperBit compression (or whatever another studio might wish to call it)...
...WILL MAKE THE FINAL PRODUCED DVD LOOK WORSE, as all of the film element and transfer flaws begin to show.
What Sony has created via their SuperBit label is a viable working example of what THX might have (and should have) been, but never became since a confused audience never understood what it was. The fact that it was sold as a product of higher quality was a misnomer, created via poorly thought out marketing. THX merely meant that the recording hardware was working at a certain index had nothing to do with the quality of the final product.
Sony, in marketing their SuperBit tradename, has created and IS DELIVERING a higher quality product, albeit one which has its greatest value when played back on the high quality systems which some of you enjoy.
