Motion Smoothness (7.0)

Typically we disable various video processing features, but in the case of the KDL-46Z5100 we found it was beneficial to leave the MotionFlow feature on Standard. This will result in some slight artifacting, but it will all but eliminate motion blurring. We really saw no issues with blurring in pictures at 1080p. A moving set of color swatches showed significant blurring, however, as did a series of black and white bars. We thought this was an interesting combination: complex pictures didn't blur much, but basic patterns did. We're guessing the MotionFlow feature is simply geared towards complex images, since turning it off caused the photos to blur just as much as the other figures.

Motion Artifacting (6.5)

Artifacting was a very mixed bag. On our photo test and color chart test, we saw very minor rolling shudder. Alternating black and white lines prove a much larger challenge for the TV: the bars were wracked with blocky shuddering and acquired a slight color cast. The shuddering was much more noticeable than the smooth effect we typically see. Herringbone patterns or high contrast stripes will likely cause noticeable artifacting.

3:2 Pulldown & 24fps (8.50)

The KDL-46Z5100 performed adequately in its 24fps mode. There were two main issues. First, the TV again has troubles with fine patterns. We saw some weird, randomly shifting blotches in a block of white and black stripes. Another block of stripes flashed slightly. This wasn't terrible compared to some of the other TVs we've seen, but wasn't great. We enabled the CineMotion feature and set it to Auto 1, which reduced the frequency of artifacting a bit, but didn't eliminate it. Another test video pans an empty stadium. The seats looked noisy (less so with CineMotion), like their outlines were crawling. Again, it wasn't a particularly distracting issue, but it will be annoying once you notice it.
