OK, spent some time with motion patterns today off the Spears and Munsil 2 disc (Resolution, Stock Ticker, X Parade and Sarah on a Hammock), using the 1080p/24 Blu-ray being sent as 2160p/24 to the LG from the Samsung UHD player. Keep in mind these are all side scrolling patterns so they really show the double imaging and blur.
• On the first 3, with TM OFF, there is a noticeable improvement when you turn RC ON.
• With RC ON, going to DJ 2 and DB 10 shows another jump in image clarity. RC seems to tighten up the edge of the image but much of the image still has some judder/double imaging. Turning TM ON clears up a lot of that double image.
• The swinging hammock really shows what TM ON is capable of, at least if you do not go too high on Dejudder (artifacts), and at 2 is an obvious improvement where RC ON vs OFF is hard to tell. This pattern is kind of a torture test.
• On 1080i/60, I used Vikings on History. This is by far the worst offender for frame dropping or stuttering that I watch, and I found one scene with a side pan and some support poles that jumped across the screen. RC on by itself fails (stuttering). TM DJ 2 and DB 10 with RC ON, fails. RC ON with DB 10 and DJ 0, fails. DB 10, DJ 0, RC OFF, fails. Only way that scene passes for me is with TM AND RC OFF.
So going forward I will leave TM and RC off for 60hz content and turn on TM and RC for 24hz content. Regardless of what those two features are or are not doing, only my eyes can tell me what has the best motion for me.
