The Vizio SV470XVT did an excellent job with motion, displaying minimal blurring and almost no artifacts, especially when the Smooth Motion feature is turned on. It also did a good job dealing with 3:2 pulldown and 24p content.

Motion Smoothness (8.0)
Unike the Vizio VO47L the Vizio SV470XVT has a refresh rate of 120Hz, and the difference is noticeable in our motion tests. The Vizio SV470XVT displayed significantly less blur at 1080p than the VO47L, especially when we turned on the Smooth Motion feature, although we would keep it at low as higher settings start to produce something of a cartoonish effect. The Smooth Motion had less of an impact with a 1080i signal, where the principal problem was some banding caused by interlace effects most noticeable on white objects. Blurring was minimal with or without this features. We were quite pleased with the Vizio SV470XVT's performance in this test.

Motion Artifacting (8.0)
We saw no major issues with artifacting on the Vizio SV470XVT, another major improvement over the VO47L. As we noted above there was some cartoonish effects if you turn the Smooth Motion feature on too high, and with it off completely we noticed some ghosting of white objects. Turn it onto low, however, and these problems disappear.

3:2 Pulldown & 24fps (9.75)
To make TV shows look more like movies, many broadcaster use a process called Telecine, or 3:2 pulldown. To use this, the display has to be able to detect and correctly process the signal, which is what we test here. The Vizio SV470XVT did a much better job than the Vizio VO47L with telecine effects. We detected none of the blockiness and jerky effects we saw on that HDTV with the Vizio SV470XVT. Our biggest issue was an occasional glitch in one area of the screen, something most viewers would barely even notice when watching regular content. The Vizio SV470XVT also did a good job with dealing with content at 24 fps, which lends a more film-like feel.
