I just bought the Hobbit and Lord of the Rings Trilogies on 4K. Immediately when I started watching the Hobbit: An Unexpected Journey, I noticed on my Sony A8H OLED TV there was a very distracting jutter happening when it came to much of the background elements in pretty much every scene. To be honest ... this is the first movie I've watched that this has happened. I didnt notice the jutter affecting any of the actors movements on screen but in scenes with moving camera shots especially wide or establishing shots the background like trees, leaves, hills, buildings, just had this awful jutter. I always turn the Motionflow and the CineMotion settings off completely. The Motionflow is where you get that soap opera effect but the CineMotion I guess I didn't really fully understand what it did. After messing about with all my picture settings I decided to try turning the CineMotion setting on to *Auto but still leaving the Motionflow off. Well after I turned on the CineMotion to Auto ... Lo and behold what did I notice? Yes the background jutter was instantly gone and those moving camera shots were now Nice and smooth and totally perfect. Problem fixed. I still don't fully understand the CineMotion setting but at least it did fix the horrible jutter when watching the Hobbit in 4K. In case anyone else has the same issue. I've never seen this before on any other movie I watched but I feel it might have to do something with the Hobbit having originally been filmed in 48fps and that maybe its just something to do with the frame rate conversion down to 24fps and then also the way certain TVs react to it. Just a guess. Or maybe Im way off about that being the reason. Feel free to correct me if Im wrong on that.
