Doesn't cinemotion have to be on high for 24fps to work on Netflix and Prime?

Only for internal apps.

All internal apps run at 60Hz. So Cinemotion must be set to High for 24fps content being output as 60Hz. Cinemotion High removes the judder and plays the correct 24fps cadence. The downside is you will notice more stutter. You can boost Smoothness to 1 to reduce the stutter but at the cost of slight SOE.

The stutter is very distracting, which is why I leave Cinemotion on Low. I don't use any internal apps, this is just my experience with external sources.

I'm not seeing stutter with Cinemotion in that video.

For my Apple TV which does correct frame rate matching and my Panasonic UHD player I leave Cinemotion off completely.

Don’t need it at all with either of these sources or with true native 24fps content.

I do however always use Motionflow smoothness on 1 for everything.

Cinemotion Low or Off is best for external sources with frame rate match.

I see really bad soap opera effect with Motionflow even at its lowest possible setting.

I just don't know how to reconcile these vastly differing experiences.

Motionflow 1 does not cause SOE at all for me for 24fps content. With that and Cinemotion on High, I get the closest the TV can get to my Samsung Plasma (96 Hz panel). I am sensitive to SOE and want to change settings on all my relatives TV's when I see it , and it is just not there with MF 1 and CM High. I have put 4 4K UHD BD movies up on this thing and they all look like normal 24 fps movies to me. Fantastic, even.

Now MF on 2 is a huge difference. There it piles on the smoothing. It's great for panning shots and nature, but you won't want it on for content with people if you want a cinematic look.

I am using a Sony X800M2 player in Bravia Mode and the TV's YouTube app, no other external devices at this time. I also do not have access to any other TV apps or services at this time for testing, which have to be what's causing our varying experiences.

For me cinemotion high and all other motion processes off is very close to plasma motion. The only time I notice a difference is on sweeping shots, I'd say less than 1% of the time. I do see stuttering on these shots but its so seldom it doesn't bother me. 99% of the time it looks perfect which was actually a nice surprise.

I have to rephrase: there is stutter on the YouTube video posted above. The only way to fix that is to go Motionflow Max and Cinemotion High, which smooths it to 120 fps.

But I do not see judder, which is an inconsistent frame rate caused by not having a proper frame cadence (what Cinemotion fixes).

Now...back to my previous post. I don't mean to say it's perfect all the time. I played with the settings during Edge of Tomorrow 4K UHD the other day because there was a scene in the base where Cage is getting suited up in a Jacket and there was stuttering on a yellow metal upright grate. It was enough to jump out at me. However, the only way to smooth it out was with a high amount Motionflow, which I won't use for this material. So I let it be. It didn't make itself obvious the rest of the movie, though.

Buy a firestick and hook direct to the Yamaha if that does not pan out.

Basically the problem is that the TV has earc while the yamaha doesn't that's why it doesn't pass me all the lossless encodings, I have the firestick and I'll try to install Kodi but having a connection only at 10/100 often the 4k movies I have on the nas they freeze, with the tv i solved it by putting a usb3/ethernet adapter and it works great, with the firestick i don't know what to do......

If you set Cinemotion to Low the Youtube video wont stutter.

Let's make sure we're clear on our terms. Stutter is inherent to 24 fps video because it's not enough to be smooth to the human visual system. The motion on the screen is definitely not smooth until both settings are at their maximum. CM specifically on low looks pretty bad on that video.

What I notice is frame skipping with Cinemotion on High, perhaps stutter was the incorrect term. Fast panning shots, or quick scene cuts is when the frame skips are noticed.

Update the Yamaha I guess?

It sounds like you're referring to judder, which is an inconsistent framerate. For example, it's fine for a second, then jumps, fine for a second, then jumps. Is that what you're seeing? I wasn't able to get it to do that and I used every combination.

I've had this TV for a few days, as far as Netflix and Bravia Core are concerned, do you recommend using the Sony-calibrated mode? But if I put this setting, I can't change anything......

Slight correction for clarification as I’m also discussing this with someone on Reddit at the moment and there was a lot of confusion about the difference between stutter and judder.

Stutter is endemic to all sample and hold displays and is due the instantaneous pixel response of all OLED’s. The only way around this is using frame interpolation.

Judder is caused 24fps content with improper 3:2 pull-down applied, but this is typically not an issue on 120hz panels. This is also where Cinemotion comes in to play. For correct film cadence detection.

No, set it to Custom.

What do you see when you play that video using the TV's YouTube app?
