Uhh, 24FPS is always choppy, even without judder. Stuttering is not even a possible result of pixel response speeds. Only choppiness. So I assume that's what you mean. The only way to "fix" this is interpolation.

So what are you claiming, that some slower pixel response times act as interpolation? Then just interpolate. Insert frame 1.5 (1 and 2 overlayed on top of each other with 50% opacity) between 1 and 2. Still not smooth enough? Just add more interpolation. There is literally no difference between this and slow pixel transitions that supposedly were timed such that they hide the choppiness. You can even do this all in software and hook it up to the TV. And of course OLED TVs can handle this as long as they allow higher refresh rates. Also some OLEDs just have this built in. Enjoy your soap operas.

> This isn't an issue with plasma screens as you get some natural motion blur with the pixel response times giving a smoother overall presentation.

I thought plasma pixel transitions are as fast as CRT?

>24FPS is always choppy

Have you been to cinemas?

Have you never noticed that a panning camera in a movie is much more juddery than a decent side-scrolling video game? Or that action scenes often lack clarity due to camera shake and related motion blur?

Or that the move from HD to 4K is near-worthless without a framerate increase?

Maybe it's not bad enough to match your personal definition of 'choppy', but 24fps is an unfortunate compromise made in the days when you had to feed costly physical film into movie cameras.

And now everyone is so familiar with 'the cinematic look', we're stuck with 'movies should look like that, as that's how they've always looked', anything different is assumed to be worse, and we're never going to learn how to do high-framerate filmmaking well as the early attempts were so quickly rejected.

I use an Apple TV to watch all of the content on my TV – streaming services, Plex, apps for TV channels, etc. Since they added the match frame rate feature[0], the judder is eliminated entirely. It's a bit jarring as the screen flashes blank when transitioning from the home screen (60fps) to video content, as the TV's frame rate is adjusted, but it's worth it, IMO.

Yes, why would that change anything? The only reason it's bearable is because they specifically engineer the movies to avoid motion above a certain speed as much as possible.
