Cool Sony X-Motion Clarity and 24p judder elimination

On my 120Hz Sony X950H, there are specific settings necessary and required for proper 24p cadence and judder elimination, when playing back non 24Hz signals, including the built in apps. The settings should be similar on other newer Sony TV's, although the capabilities of 60Hz panel models, such as the 800 series, may preclude the possibility of judder elimination.

For proper cadence, where each 24p frame is held for five 120Hz refreshes, you MUST engage Motionflow/Custom Clearness ON, and CineMotion ON. You must also TURN OFF Smoothness. If you turn off Clearness or CineMotion, or turn on Smoothness, the playback frames will be 3:2 60Hz, or randomly generated interpolated chaos. This applies to external HDMI sources that are anything other than 24Hz, as well as the internal TV apps, which are 60Hz natively.

To see for yourself, go the the YouTube link below, and while playing back the judder tester, use your mobile phone or a camera to take a 1 second exposure of the screen. You may want to use the manual mode for exposure, and be sure to turn the ISO down so as not to overexpose the 1 second picture. With the proper X-Motion Clarity settings, the resulting photo should have all boxes of similar brightness, 1 frame, shown 5x, that is 5:5. With CineMotion or Clearness turned off, you will get a clearly defined checkerboard patter, with the brighter boxes being shown held 3x, while the dimmer ones are shown 2x, that is 3:2 pulldown. If you turn on Smoothness, you will get strange random patterns of brightness, as well as black boxes, with no even and proper cadence...at least not on the judder test...if you like Soap Opera effect, then cadence isn't something you'll probably notice anyway.

Thanks for this. With X1 Ultimate settings are?
Smoothness = min
Clearness = 1
Cinemotion = auto?

Correct, CineMotion on Auto, Smoothness Min, and Clearness at 1, 2, or Max. Clearness at Max with Brightness at Max is roughly the same luminance as 100-120cd/m, FYI.

A little bit of a clarification, for just Judder elimination without also using X-Motion Clarity, turn Motion to Custom, with Smoothness and Clearness both set to minimum, and CineMotion set to On/Auto. Setting Clearness to 1, 2, or Max will do the judder elimination and also add black frame insertion for better motion handling...Smoothnes is the fake frames soap opera effect.

Thanks again. The motion settings are confusing. At least with teh newer models tehy hae fewer options to sort through. I dont like SOE even though Sony interpolation is better than most. The settings I mentioned earlier are good for any use case? 24P/60P and 1080i OTA?
