National Geographic: China Circus On Ice (2009) 720p

China Circus on Ice offers a slightly below average visual presentation. Filmed in high-definition using digital photography, the show contains a reasonable level of fine object detail, but there's still a certain degree of haziness that creeps in from time to time. If anything, I'd assume the lack of precise edges or outlines are a result of problematic tracking in the interlaced encoding. By nature, 1080i tends to generate an image that seems a bit rougher in comparison with encodes that utilize progressive scanning. Another unfortunate byproduct of the interlaced versus progressive debate, is the presence of occasional artifacts that appear during panning shots. The artifacting seems to rear its head during scenes with an intricate collection of lines, where the movement of the camera doesn't allow the interlaced frame to refresh quickly enough. From a color standpoint, China Circus on Ice consists of a spectrum that's entirely natural and unaltered. From the bright shades of the acrobat's costumes, to the colorful backgrounds of the stage backdrops, everything looks exactly as it should. Along the same lines, black levels never wavered, and contrast appeared equally strong during interior or exterior scenes.
