    Can anyone help, before I embark on a long trial-and-error process?
    I'm trying to reduce stutter (not judder) on a 55H7000. The relevant controls appear to be under the menu item called 'Motion Plus'. Under this, in Custom mode, I can adjust 'Blur Reduction', Judder Reduction', and 'LED Clear Motion'.
    I can't work out which of these will best address stutter. Can anyone help? Otherwise it will be trial and error! Thanks in hopeful anticipation.

    Set Blur and Judder to 0 and go from there.

    It also depends what you are trying to playback and from what source, as these will have to match the frame rate of the tv.

    What is stuttering on the tv?

    Essentially off-air via a Humax. I'm assuming that the culprit is the TV and not the Humax.

    Is the Humax set @ 720P/1080P?

    I had it set to Custom, which was Blur Reduction = 0, Judder Reduction = 5, LED Clear Motion = OFF. I've now set Motion Plus to OFF, and will monitor the result. I guess I should go through all the Motion Plus options.
    Thanks for your interest.

    Also, if you set the Humax to 1080i, you should see a Film option you can select, for better motion.

    Hmm … I don't get any Film option with 1080i, on either the most recent Humax box or the one before. I'm using FreeSat boxes, so perhaps you are referring to the Freeview variety?
    Not sure a 'Film' option will make a difference to stutter, but might reduce judder.

    There may be a film mode within the TVs settings - not a picture preset. I think that’s what atmos is referring to.

    Thanks, yes, you're right. It's greyed out for 1080p but has options Off/Auto1/Auto2 with 1080i.
    I'll play with a few settings, to see if these make any different to stutter - though I think they are really intended to address low frame rate judder.

    It has Film Mode option and latest software is 23/4/18.

    Have you only got a Freesat box to try?

    What about a Freeview box, or built in tuner?

    Yes, in 1080i I see Film Mode. Prefer Auto2 over OFF, but I've only seen a difference in judder rather than stutter. But really feel I should be using 1080p anyway.
    I guess I could try the inbuilt tuner, to eliminate the FreeSat box from the equation (but thereby introducing a new unknown!). No FreeView feed to the room. As it only happens occasionally according to the change in action on the screen, it could take a long time to work out which are the best settings.
    I really need to carry on with the Humax FreeSat and HDMI in to the TV, and work with all the variables between the two. I just thought someone might have see this occasional stutter and cracked it.

    A reboot of the Humax might help or a reset.

    Hi

    Don't bother trying, you will never resolve it completely. Samsung TVs seem to have a problem going from static content to motion, the start of camera pans often confuse them, and the judder or stutter is due to frames being dropped. Even with no motion settings enabled, what should be relatively smooth 50i video is often de-interlaced badly and seems to drop frames some times.

    I used to always own Panasonic TVs (not 4K but HD) and never had the judders and stutters and issues I see now on my Samsung TV, the picture processing is rubbish.

    If you want some fun, on a Q7F 2017 model try switching the TV to Movie Mode and with any Auto motion plus settings enabled, you will find random white flashes inserted at edit points depending on the footage. In a dark room it's like someone is at the window taking flash photos!

    Regards

    Phil

    Hi Phil.

    Can you tell me your Natural picture settings please?

    Thanks.

    I have the same issue on a 2018 55NU8000.

    I set motion options to custom, blur to 0 and judder to 2 (as I was seeing judder on slow plans).

    I still get the stuttering, and it's really annoying. Seems to happen a lot when watching Strictly, lots of movement, but has also happened on Bake Off!

    My 8 year old Samsung never did this.

    I'm assuming it is the TV as that is the only thing that has changed. Source is recordings from a VM Tivo, via an AV Amp.
