Motion blur/distortion on fast moving video scenes

Those are typical interpolation artifacts. The motion interpolation technology gives off heat wave/shimmer like artifacts around objects kind of like when you have a BBQ and you see those clear wavy mirage phenomena rising above the flames or behind the hot exhaust from a fighter jet like this: http://i745.photobucket.com/albums/xx94 … C03452.jpg It's like an outline or aura around objects during the interpolation process. You can see them if an object/person is stationary while the background is moving or moving the opposite way against the way that the object/person is going it seems. I'm not exactly sure why interpolation causes this, but it's one of the types of artifacts caused by the technology. There's nothing wrong with your system, it's how interpolation works.
