Motion Performance

Motion Smoothness (8.13)

The Toshiba 46XV648U did very well in our motion performance tests, living up to its moniker of 'Cinema Series.' In order to bring out the best performance, we experimented with the Toshiba's special motion processing features: ClearFrame and Film Stabilization.

In our testing, we found that the ClearFrame feature had a significant impact on the TV's ability to maintain fine detail in moving objects. The difference between leaving ClearFrame on and off was obvious. But in certain circumstances, turning on the ClearFrame feature seemed to create some strobing artifacts.

Overall, the performance was better with 1080p video than with 1080i. High-frequency, high-contrast patterns like black & white stripes gave the Toshiba 46XV648U its biggest problems in 1080i.

Motion Artifacting (6.75)

There were definite instances of motion artifacting in both 1080p and 1080i footage. The strobing, mentioned above, would occur more often with the ClearFrame feature off. But when ClearFrame is turned on, strobing would occur in completely different areas of the screen, likely a result of converging correction processes failing.Nevertheless, the Toshiba 46XV648U is a strong performer in motion performance, overall, but you do need to play with the special features to get the best picture, and those settings may have to change depending on the content. More on how we test motion performance.

3:2 Pulldown & 24fps

The Toshiba 46XV648U can manage 3:2 pulldown from native 24p content, but in the video looks very choppy when it pans horizontally. In order to correct the problem, the TV has a feature called Film Stabilization. There are a few settings for this feature, and only the strongest setting managed to smooth out the 24p footage. But this setting may have an effect on the quality of the picture that you don't like. It's strictly aesthetic and entirely up to the user. More on how we test 3:2 pulldown and 24fps.

Resolution Scaling

The Toshiba 46XV648U is a native 1080p television, but a lot of the content you watch will likely be of a lower resolution. It's up to the TV's processor to upscale that footage so it fits on the screen. Fortunately, the Toshiba 46XV648U is very, very good at this task – better than more expensive TV's we've seen. Details are below for each resolution we test. More on how we test resolution scaling.

480p

This is the lowest resolution you're likely to see. The Toshiba 46XV648U lost no screen area to overscan, though we did see a lot of Moire patterns in high frequency areas.

720p

Footage in the 720p format also lost no screen area to overscan, and managed to stave off most problems associated with upscaling.

1080i

The 1080i footage looked nearly as good as native 1080p, with only the slightest Moire patterns in high frequency area.
