SUMMARY

The discussion centers on the perception of motion when viewing content on UHD TVs, particularly focusing on frame rates. Users report that higher frame rates, such as 240 fps, can create a choppier appearance rather than a smoother one, contradicting common assumptions about motion fluidity. Observations include that UHD OLED screens can make indoor scenes appear overly artificial, resembling film sets, and that close-up details of actors may detract from the viewing experience. The conversation highlights a disconnect between technical specifications and subjective viewing experiences.

PREREQUISITES
  • Understanding of UHD (Ultra High Definition) technology
  • Familiarity with frame rates, specifically 30 fps and 240 fps
  • Knowledge of OLED (Organic Light Emitting Diode) display technology
  • Basic principles of motion perception in visual media
NEXT STEPS
  • Research the impact of frame rates on motion perception in video content
  • Explore the differences between OLED and traditional LCD display technologies
  • Investigate the effects of high-definition formats on viewer experience
  • Learn about the psychological aspects of viewing media and perception of realism
USEFUL FOR

Film enthusiasts, UHD TV buyers, content creators, and anyone interested in the effects of display technology on viewing experiences.

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?

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...
