I haven't seen a native HFR movie. Watching a movie shot in 24fps -- or a TV show shot in 29fps -- on an HFR TV looks absolutely terrible. But I'd like to see a 48fps movie on a TV that can properly display that without interpolation.
But then again, I have a Panny PDP, and I have heard that for cinematic content, the interpolation is better than watching in multiples of 24fps due to excessive judder (or was it an excessive shutter-like strobe effect?). I wonder if the same would hold true for true HFR content?
However, there doesn't exist a native way for HFR content, right? I'm not aware of an HFR Blu-ray spec... is there any way we can test this theory for movie content? I'd love to.
