Video: How Does The Disc Look?
The film's theatrical aspect ratio of 2.35:1 is presented in anamorphic video. This is a very respectable THX certified transfer, and from what I've gathered elsewhere, must be orders of magnitude better than the previous DVD release. Halos are present in various degrees of severity depending on the content of the images. It varies from being totally absent to a full cycle of visible ringing. The overall appearance is slightly soft, complicated by the optical flaws in early wide-angle anamorphic lenses. In some scenes, a noticeable loss of focus at the top edge or bottom edge (or both edges) of the frame is clear. And the depth of field, perhaps due to the limitations of lighting in the onboard spaces and the apparent low speed of the film, causes focus problems as well. Colors are very nice, clean and smear free. Flesh tones are natural. Shadow detail is less of an issue here; the only dark scenes I can remember were within the vortex, when visible details simply weren't important. The film really shines when we're airborne; the flight sequences are magnificent.
Audio: How Does The Disc Sound?
The audio has been remixed for this DVD release. There are two 6.1 tracks, one in Dolby Digital and the other in DTS, as well as a Dolby Surround 2.0 track. The 6.1 tracks feature very active and effective surround channels, with lots of off-screen audio action. The mix is nicely done with the exception of John Scott's score. The orchestra is mixed into the back surround and it's quite disconcerting to hear the cymbals behind you as the rest of the musicians play in front. The musical soundstage is also a bit narrow, creating a slightly claustrophobic effect. The fidelity of the sound effects and the music seems to suffer from the budget as well. The musical instruments seem compressed and band limited. Voices suffer from a hint of raspiness that could have been caused by the analog recording techniques of the day or by digital compression artifacts. Very deep bass is not present. The sound mixer missed a great opportunity to mix in some deep, band-limited noise to supplement the jet engines. As for the inevitable comparison between Dolby Digital and DTS, the fidelity of the audio stems simply isn't high enough to warrant a preference.
Subtitles are available in French, Spanish, and English, for which Closed Captions are also included.
