Even if you duplicate them 5 times, you are still dealing with 24 unique frames. What you don't see is the judder, not "new" frames that duplicates the feel of 60fps video. My TV has TWO algorithms for 24p, not one like LCDs do. It has the interpolation trick and the 72Hz. None of the two look like video. I am watching "Full Metal Jacket" as we speak, and I have changed back and forth between the two algorithms. I re-iterate: none looks like video. Michael, 24p is 24 frames.

It is different from simply raising refresh rate to 120Hz, but is not possible without high refresh rate. Yes, I saw it myself both on Sony and Samsung. 120hz refresh without Motionflow looks nice, 120Hz with Motionflow looks like cheap video. Motionflow creates new frames, which is visually equal to watching a movie shot with higher frame rate. Yep, looks like crap, just because it is not 24 fps anymore. This did not mean to rain on your Pioneer, this was a retort for "24 fps does not give movie look" statement. See, I did my tests this time, so I am commenting. If you haven't been to an electronics store lately, look at new Sony XBR next time. Keyword was “motion interpolation” or in Sony-speak “Motionflow”.

And I am sorry, but you don't know what you are talking about. You see, that feature (72Hz/120Hz/48Hz) is about making it look LIKE it's on the theater (theaters these days use either 48Hz or 72Hz projectors). So no, the cinematic value is NOT lost, it is in fact ENHANCED by this feature. That's the whole point. And so it certainly does not look like a cheap video. I watched a number of movies and 24p series since we got this Kuro TV at the beginning of the week (in Blu-Ray, with 24p player support), and it doesn't look like video AT ALL. I think you should buy such a TV and test it yourself instead of re-iterating misguided crap by clueless people on the web. Please do your own tests, and then comment.

No background blur, no DOF shots, no film grain. And yet, it looks cinematic. This just shows that the “movie look” is not 24p, it’s not even DOF, or film grain." The movie is shot with Sony Cinealta HDC-950 in 24p, which is why it exhibits film look (more precisely, cinematic motion look). Have you seen new 120Hz TVs with motion interpolation? Movies look like cheap video, all because 24p magic is lost. Yes, I know, I am annoying. But I suppose you have enabled comments in your blog for other people to comment, so commenting am I. “And speaking of Star Wars. No background blur, no DOF shots, no film grain.
