Page 7 of 9The rather empty, on-screen interface Sony provides for making these selections leaves much to be desired in providing information about the effects of these adjustments. Lots of dead space! Being able to see a representation of how the different settings impact the content you’re viewing in the moment would be a much welcome feature of the interface.
Even Sony’s printed instructions provides little in the way of understanding just how these features should be optimized for viewing different content sources. It would seem the designers of the 46Z4100 user manual ran out of gas when it came to illustrating these crucial visual concepts. Instead, they allocated their graphic budget to “Exploring Fun Features” such as Favorites, the TV Guide, instead of more clearly explaining and demonstrating elements that would most effect picture quality.
Insert the added factor of the source device, e.g., Blu-ray player, having a variety of selectable, some forced, or automatic output settings for resolution and frame rate and it’s no wonder this is one of the most complex areas to understand for consumers, and is even the subject of differing views among industry professionals.
CineMotion is more of a traditional inverse pull-down processor to better display film-based content. The attempt here is to deconstruct, then reconstruct the mix of film frames in video fields in order to eliminate the encoded overlap and image smearing. Again, 24 fps film transferred to 30 fps (60 fields per second) video contains built-in picture and timing flaws that CineMotion attempts to correct. In addition to turning the pull-down OFF, there are two settings, Auto 2 and Auto 1. Auto 1 is the suggested mode for regular use, as it is supposed to apply to a wider range of content. TV broadcast, cable and satellite in particular can be a bewildering mishmash of film and video formats, encoding schemes, etc. It adds more processing for a smoother picture. Auto 2 attempts to retain the characteristics of film, so is more appropriate when assigned to sources like Blu-ray and DVD.
Admittedly, I did not have access to the FPD Benchmark Software Blu-ray disc when conducting my review. For a more comprehensive analysis of these particular features, I’d recommend reading the November 2008 review here on AVRev of the 40” version, the KDL-40Z4100, written by Adrienne Maxwell, who goes into extensive detail on both Motionflow and CineMotion.
