Actually human eye can capture around 60hz. It's practicaly visible in FPS games for example.
Example: switch black and white frames, and increase rate of frame switch, when you see solid grey that mean you reach eye perception. That was done practicaly.
50 Hz is already higher than your eye requires, 100Hz is your eye cannot capture at all, and there is 200hz too which is a overkill.
100hz or 200hz is indeed missleading wrong understanding same as LED TV description.
Whole thing is not about increasing TV refresh rate in display. I'm not sure if tv is capable full 100hz on panel display, it can on upto 75hz using as monitor. so maybe it can 100hz.
Whole thing is about smooth playback frames.
So there is smooth playback if you are being 200 hz camera. But your eye is comfortable even with 24 Hz Cinemas!
You mentioned cinema, it's visible flickering.
Anyway, if you record on "slower capture" camera, you will get smoother result due resulting motion blur effect.
If you record on faster camera and play on slower you get not smooth quality.
Similiar thing is with how many pixels camera have. If it got a lot more noise you get.
100Hz means nothing but false advertisement. You can't make pictures clear with increasing Hz thing.
Yes, it's wrong advertisement same us LED TV. And I think you pointing this to as display refresh, I didn't say anything about refresh rate before, but 100hz mode as video postprocessing.
Scientist/Corporations tried to remove this Hz thing at LCD's. They thought that while they can independently adjust each pixel alone, there is not needed that "scan" tech.
But without black frames between pictures, eye/brain remember older picture at top of new one. That leads blurring. So they revert back to scanning tech again.
If you accelerate movie, that means less black frame between pictures, and your retina try to remember picture showed before, that lead "ghosting" self.
Yes, it's eye/brain perception thing. Also that 100hz mode post processing trying "remove" that effect.
It also trying remove scuttering effect for example while scrolling texts.
I don't see a video media that is in 100 fps playback too. Is blurays supports 100 fps? Since media is 60 fps, there is nothing to talk about TV has 100hz. If 60Hz is not enough, why all movies are sold in 60Hz?
Because of size of video format ?
Eyes first capture details than movement, so frame rate is less important. Also doesn't mean bluerays and other players can't have video postprocessing.
All things depend how video is recorded. 100hz can make things worst too, For example creating too much blur motion effect.
That's why you can customise that mode. End user video can be re-encoded with loosing proper motion and grain quality. Broadcast tv is also reencoded.
Similiar thing is in audio processing and still analog devices are best in audio processing.
Creating sub frames is nothing important. Might be in practice, cures devices poor performance on 60Hz.
But I prefer "proper 60 Hz" instead of advertised 100 or 200 hz...
It's wrong statement by missunderstanding whole tv video postprocessing mode.
