Blu-ray 1080p24 playback at 60Hz or 72Hz. Does it really matter?

    Hi everyone,

    Since the 6G, Pioneer Plasma TV's were already capable to play 24fps based content at 3 x 24 = 72 Hz for judderfree, smooth playback.

    Now, I would like to know, how the new Samsung PS50P96FDX 50" Full HD & the new Panasonic TH-50PZ70B 50" Full HD handle this 1080p24 signal. Are these sets really capable to play Blu-ray / HD DVD as smooth as on a Pioneer Plasma TV?

    And what are they doing with the 1080p24 signal? Do they multiply and divide the frame rate in real time like this 24 x [-]3[/-] 5 / 2 = 60 Hz :rolleyes:

    :lease:

    Hi glen8,

    I just saw in your signature that you have both the TH-42PZ70 and the PS3 in your HT setup :cool:

    How do you experience the smoothness when you play the end score of a Blu-ray movie or during horizontal panning shots with your PS3 setup to output in 1080p24?

    Cheers,
    Fico

    :oops:

    Maybe 24 * 5 / 2 = 60 Hz then?

    I really don't know what these TV's are doing with the 1080p24 signal :confused:

    Isn't it just normal 3:2 pulldown

    1080p24 frames are: A B C D

    1080p60 frames are: AAA BB CCC DD

    So frame A is repeated 3 times, then frame B repeated 2 time, then frame C 3 times etc.

    So the maths is 1080p24 has 24 frames per second, of those 12 are repeated 3 times making 36 frames, the other 12 are repeated twice making 24 frames, then 36+24=60

    The Panny commercial screens are perfectly capable of displaying 24, 48, or 72Hz signals. I don't see why a limited version of this can't have been included in the PZ70. I wouldn't assume it's converting it to 60.

    Surely it will just take someone to compare a 1080p/60 pan to a 1080p/24 pan and see if it's smoother?
