Why is frame interpolation so easy to notice? Interpolating audio can be transparent because aliases of the signal are removed.

Traditional LCDs do a "zero-order hold" to fill the theoretically infinite time between frames:

But interpolation then requires filtering. Are the 24 to 60 FPS judder artifacts the result of the lack of filtering because it's just "upsampling?"

Are frame interpolation algorithms just too expensive to produce a transparent (no judder or artifacts) sequence in real-time? I imagine that each component of every pixel would need to be treated like a separate waveform, with zero-stuffing and then filtering.

In contrast but analogous to LCDs, plasmas use impulses of light instead of the zero-order hold of LCDs. So a plasma might quadruple each frame of 24 FPS video to produce 96 FPS. Isn't this basically a less-perfect zero-order hold with zero-stuffing and no filtering? Somehow that's perceptually better?

Does the plasma method simply look transparent enough to not require a filter to make it true interpolation?

Obviously video requires a lot more data than audio. Is that the only reason for such different approaches to sample rate conversion?

Also, I suppose shutter speed influences how much blur is contained within each frame, which I guess is like the noise floor. Yay photography.

As you may have heard, Frog Fractions 2 is out. My favorite section was what I call Where In Hell Is Carmen Sandiego, with this song.
