    Perception Time
Click For Summary
The discussion centers around the experience of watching content on a new UHD OLED TV, highlighting a perceived difference in motion quality and image clarity compared to previous models. The user notes that higher frame rates do not seem to produce smoother motion as expected, instead appearing "choppier." This leads to concerns about the realism of film sets and models becoming more apparent, particularly in indoor scenes and with special effects. The user also expresses disappointment in the close-up portrayal of actors' skin, which appears less flattering in UHD, prompting reflections on the perception of aging. There is a curiosity about the impact of higher frame rates on viewing experiences, questioning the necessity of technologies like 240 fps when lower frame rates may seem smoother. Overall, the conversation critiques the effects of UHD technology on the enjoyment of films and the realism of visual storytelling.

I'm posting this here because physics can't answer it. Neither is it philosophy. I was watching the first episode of Lucifer over again on my new UHD TV. My old UHD took a crap and it was low fps. Now watching my new TV I noticed motion looks different. I don't think it seems smoother like my intuition would lead me to believe. It kind of looks "choppier" at a higher frame rate. I wonder how mathematics could reconcile this contradiction.

Curiously, on the UHD OLED screen, most of the indoor scenes looked too-obviously like film sets. And the space vehicles looked too-obviously like models, though not quite as bad as the original Star Wars.

Now I'm wondering whether watching movies on OLED from a 4K bluray source will ruin them for me. :oldcry:

Has anyone else had this kind of experience with UHD?
Keep these comments/critiques of UHD coming.

Really? I could go on all day...

E.g., I was surprised just how poor your average "beautiful" movie starlet's skin is when seen up close in UHD. :oldruck:

And as for middle-aged or older actors (of either gender)... yuk. I have to keep telling myself to concentrate on the storyline, and just accept that the actors are real humans with all the usual flaws.

But this is not really a "perception of time" thing. More like "perception of aging". :frown:

I've been "bothered" by this for a week now. In reality motion is smooth. When I go into the TV section and look at all the higher priced TVs with 240 fps I think to myself what is the point, since I thought you can only notice the discontinuity at much lower frame rates. For example if there was a black frame inserted every 60th frame at 60 fps you wouldn't notice it consciously, as in "subliminal programming" but perhaps I'm misinformed. I just can't imagine how 30 fps would seem smoother motion than a higher frame rate unless perhaps the pixels have a faster response time making the images sharper.
Perhaps I'm just crazy even though the voices in my head tell me I'm not...
