Someone asked the other day what the sliders under 'Auto Motion Plus' do, so here are all the different values on the JU7500.
Both interpolate and create the soap opera effect. However, they don't affect the same type of content. 'Reduce Blur' only affects 60 fps content. 'Reduce Judder' is for lower frame rates. That way, if you'd like, you can turn off the interpolation only for movies.
As you can see, increasing the sliders increases the effectiveness of the interpolation. Also, the threshold of detection is increased, which improves the sensitivity when tracking fast moving objects.
