    Hi all,

    I've recently upgraded to a 65" Panasonic ST50B.

    I've noticed much more on this big screen that it juddered and blurs more when panning left and right at a reasonable speed. Do others find this? The frame rate is correctly set, 50hz Sky, 60hz or 24hx blu ray etc. Panasonic said its normal and I've read nothing in the reviews saying it does it so wondering if its just me, bit it definitely jumps frames on a faster pan.

    Panasonic intelligent frame correction can help but it "hiccups" to often to make it watchable.

    Thanks,

    Ian

    Can't be, the reviews were awesome and never mentioned it. None of them.

    That is because they generally don't mention things that all TVs exhibit.
    I do agree that it is distracting when you first notice it, but IFC, or ignoring it, are the only "cures".

    Edit,
    Just found the post from years ago that led to me understanding the effect which may help.

    So what are we saying here? The ST50 that got rave reviews from all the respected sites including this one is deficient in movement or are we saying this problem affects all TV's?

    ^^^ That is it in a nutshell.
    Now you know what you are looking for, you'll be able to see it on all TVs.
    A lot of (poorer) sets will blur the image which will make it more difficult to spot, or less noticeable if you prefer.

    Yep the irony of a great clean image. Im sure many 'issues' people have are not actually the fault of their sets, that's why you need to use a bluray to see how good a set is PQ wise. Of course you may want a set that handles handles scaling etc but the source us rubbish there's not a great deal a set can do.


    Mind you even the content of a bluray May make you think there's an issue.
    I remember watching blue planet for the first time, the bit with the polar bears made me think there was something wrong, all that juddering:eek: I felt like a proper plonker when I foundout how far the camera had to zoom in, the judder was the camera man:laugh::facepalm::blush:

    Ok thanks. So why is blu-ray meant to be less jerky then, when it is displayed at only 24 frames per second rather than the surely better 50 frames per second of Sky and 60 frames per second on the jerky as hell Xbox and ps3?

    Blurays outputting 24p are refreshed by 4 so the screen is at 96hz refresh rate. I see a slight judder but its a constant judder.
    Broadcasting is a different kettle of fish. Yes is 50hz but it also depends what your watching, movies will under go some tinkering to go from 24p to 25fps x 2 so there can be motion artifacts from the broadcast side, if its USA show things have to be changed to suit 50hz, then there types of camera used, directors intentions for the show, time spent editing to suit the broadcast etc etc.
    Xbox and PS3 will either look super smooth when running at 60fps eg call of duty or juddery from anything less and as computer games frame rate isnt stable things can vary.
    If you have Final Fantasy 13 on the PS3 the cut scenes look smooth and bloody good, there at 60fps @ 1080p/60hz. The main game drifts around 30fps 1080p/60hz so panning the camera slips the fps up and down creating a judder effect.
    The only time we will see a console looking smooth no matter what the game is when the next gens come out. PC gamers have had the luxury of silky smooth fps due to a decent PC system.
