I'm sorry but you're wrong. Cinematographers do not worry about 24fps judder. There is such a thing as shutter speed which in the vast majority of film shots is kept fairly slow, having the effect of blurring the action. An example of fast shutter is Saving Private Ryan's battle scenes. The frame 'judder' in these scenes was the whole point of that style of cinematography and has been a template for many action films since, so I wouldn't have thought Janusz Kaminski would want someone pissing on his technique with interpolation after the fact.

The reason 24fps has been the standard for nearly a century (and hopefully remain so, in spite of witless feature preachers) is that it's the closest approximation of how we perceive motion. You don't move your head or eye in a perfectly smooth line, there is a slight judder and your brain blends it together.

Go to a cinema and count the number of times the filmmakers or projectionist have used interpolation in a given film because it looks a bit juddery...

Or you could stop spewing this drivel which no doubt may have some influence on the many poor souls out there awash in a confusing maelstrom of technobabbling marketing speak.

My advice to anyone who wants the best and most faithful home cinema is to emulate an actual cinema - turn off all 'enhancements', noise-reductions and such. Only buy gear that looks - to you - as close to a cinema image as possible and that doesn't [censored] all over the pure signal from your source.
