Star Trek IV: The Voyage Home

In Star Trek IV: The Voyage Home, it's the 23rd century, and the crew of the U.S.S. Enterprise must return to Earth to stop an alien force that is destroying the atmosphere. To save mankind, Kirk and his crew must travel back to 1986 San Francisco, and what they encounter there is every bit as alien as what they've seen in the outer reaches of the galaxy!

The 1080p AVC encoding looks clean and well defined, with source element artifacts almost completely removed and fine details displayed beautifully. Images have a slightly soft appearance, though details and definition are generally nicely rendered. Colors appear a bit dated and occasionally border oversaturation, but can otherwise seem pleasantly balanced. At times, shadow delineation seems to drop off, lacking definition in the darker scenes. Still, contrast is generally satisfying, and black levels are deep and consistent. While the source element is rather clean of flecks of dirt and minor film grain, what is there can expectedly appear amplified in some of the effect shots. (Danny Richelieu/Suzanne Hodges)

The Dolby® TrueHD 7.1-channel remastered soundtrack sounds slightly more refined in the rendering of dimensionality and the midrange over the DVDs, and also has a bit more prominence in the low-end. Fidelity is quite remarkable, considering the age of the production, as hissing and humming distortion have been cleaned up very well. Sound effects are effectively placed throughout the listening space, with each of the channels used effectively. The addition of the surround back channels helps create a more refined surroundfield, with good integration with each of the used channels. The music is spacious and dynamic, with an expansive, engaging presence, and dialogue production is quite exemplary. Low-frequency output from this soundtrack is powerful, with extension down to below 25 Hz from the LFE and other channels. (Danny Richelieu/Perry Sun)
