Oops, your right. That'll teach me for trusting something previously posted on the AVS Forum!
has a better understanding here is a more in-depth discussion on Blur and Judder...
As Sly Stone would sing, "Different Strokes for Different Folks." Therefore, Samsung supplies five settings for Auto Motion Plus 120Hz: Off, Clear, Standard, Smooth and Custom.
The TV always runs at 120 Hz.
When AMP (Auto Motion Plus 120Hz) is off, the TV just takes the incoming signal and duplicates it to make 120 fps. If the source is 24p, then the TV plays that back as 24x5, which means there will be no 3-2 pulldown. If it's 30 or 60p, it just plays the signal back at 4x or 2x, respectively.
When AMP is on, various amounts of interpolation are applied.
The interpolation can be adjusted separately for film (24p sources) and video (30p/60i sources). Some people complain that interpolating a film image creates a higher frame-rate-image that looks too much like video, because video has an inherently higher frame rate. You lose the judder that is inherent in film (for examples, see the card-dealing scene in Casino Royale, or the Quidditch game scene in the first Harry Potter movie).
The Custom setting offers a Blur and a Judder reduction setting. Blur reduction changes the amount of interpolation for video sources. When BR is set to 0, there is no interpolation applied to video sources. At 10, the maximum amount of interpolation is applied.
Judder reduction changes the amount of interpolation for film sources. Similar to BR, When JR is set to 0, there is no interpolation applied to film-based sources and at 10, the max amount is applied.
If you don't like the 'video-ish' effect on film-based sources, you can increase Blur reduction (to get the motion resolution improvement for video sources) but reduce judder reduction (to limit, or eliminate, the 'smoothing' effect on film sources).
The preset settings apply blur and judder reduction to varying degrees:
Clear - Blur is preset to High, where Judder is preset to Low.
Standard - Blur and Judder are both preset to a middle level
Smooth - Judder is preset to High, and Blur is preset to Low
It is possible for the interpolation, particularly when set to the maximum, to create brief artifacts in complex, fast-moving images. This occurs less than 1% of the time with regular content. If this is bothersome, we suggest lowering the respective adjustment (or switch to the Standard AMP mode, which is the default, and keeps both adjustments at a midpoint)."
