>Are there specific cases where "HFR" videos are really improving the viewing experience of particular (types of) content?
Yes. Every single one. It's that simple.
Yes. Every single one. It's that simple.
I've found that zero of the videos that I've ever seen that were 60fps improved things: certainly if I went full screen I could notice the resolution of 1080@60 versus 720@30, but in a standard browser window it was none.
Yes, my vision tests are fine.
On the other hand, when I see a video where someone's talking is recording from across the room with a camera mic in an untreated room, I'll just turn it off. I guess I'm a big snob for certain audio things.
Video resolution though? Never cared.
If I open a browser window and click on a YT video suggested on the main page, it plays on small portion of the screen of my 14" MacBook: there is little practical visual difference between 720 and 1080 at that 'video box' size.
If I open the same video on my 27" 5K iMac and full screen it there, then yes, there is a difference between 720 and 1080 (and 4K) there.
But I find 60fps does not improve the content / experience in any situation.
But if you tuned to a random channel, most people couldn't tell you if what they are looking at is SD or HD. "It's all digital, right?"
Again, if you then swapped to the HD version, they would immediately notice.
But we had so many stories of installers visiting customers homes on service calls to be confronted by massive TVs displaying 480i or 480p. And the customer as happy as can be with the picture quality.
And there were two version of this; (a) Two physical channels, one channel SD and one channel HD, and (b) a single HD channel and the DVR is can be set to down convert to SD.
