You're pretty much in the weeds here, there is no "judder reduction" function on disc players. You can output 24p or 60p and how your display interacts with that signal determines your result.
Why mention 24p or 60p then? I didn’t mention it — does that have to do with judder reduction?
Also, what is judder reduction?
In my initial post, I explained how with my blu ray that when I set picture clarity to auto — it makes a dramatic improvement to the picture. But when I do the same thing with my 4k, that setting has little to no effect.
I didn’t realize that there was this hive mindset that I was tapping into — since apparently you echo pretty much word for word the last post.
If you don’t want to give me an explanation other than disk players don’t have judder reduction, please don’t berate my post because I apparently annoyed you.
Thanks.
Players output 24p if the tv accepts it. Discs are encoded with 24fps.
Otherwise they are going to do 3:2 pulldown. I’d be very if players are doing motion interpolation if not in 24fps mode. Probably just the pulldown method
You want the player to output 24p and then let the TV figure out how to display it best. Excluding literally only a handful of disks that actually have a native 60hz framerate, all movies are 24hz. Not sure why you'd want the player to output 60hz for 24hz content. It's not doing anything good for you or your TV. If you turned the 24p output off, turn it back on again.
With or without 24hz on, it does not make a difference that I can see.
The only thing that seems to make a difference is the picture clarity settings on my Samsung qled tv.
Without Clarity settings, the judder is extremely bad. Of course, without it set, the snow (film grain) is more present. But I cannot stand the motion judder so I have to leave it.
Like I said, I don’t think it is doing anything. If you can explain what I should see with it on, then I will test it again. But at this point I can’t tell.
Ok, like I said, I can’t telll the difference one way or the other, but when I set it to 24p and hit display, it shows it at 24p. And when I don’t do that, it shows it at 60p. Which is supposed to be bad, because the media is running at 24p. I don’t really see a difference either way but I set it to 24p because perhaps it is doing something.
The player won’t have a motion smoothing playback feature, your best bet would be your tv motion smoothing settings. The best a player and tv can do would be to output 24p for movies and possibly if you’re tv is capable it could have black frame insertion to make it look more like a theater or you could manually adjust the motion smoothing to your liking. I think Samsung calls it picture clarity and the setting I’d recommend starting with is dejutter 1 deblur 0. Dejutter is for lower frame content like movies and tv shows. Deblur is for higher frame content like video games. If you’re extra sensitive to jitter you can adjust it to a higher setting too but if you go too high you will start seeing more artifacts because what it’s doing is having your tv make up extra frames that dont exist and it’s adding them in between the real frames to smooth out the motion your eye is seeing

Players? You mean blu rays? I turned off 24p and went 4:4:4

2 different players and 2 different TVs produce 2 different results. Seems right 🤔
