Does anybody have any idea what this post is about?
I think it's the frame interpolation feature that a lot of TVs have.
It’s a terrible effect, and people who don’t spend much time in their TV’s setup may not know or think to turn it off - or they delude themselves into thinking they like the effect.
If you're watching a tv and the frame rate hitches all over the place every few seconds then one of these stupid fucking settings is on.
The shit wouldn't be so fucking awful if it could actually maintain a stable frame rate but it can't. None of them can.
Motion smoothing, frame interpolation features in TVs. It's what makes movement look unnatural and on default TV settings. Old people can't tell/don't understand so it's customary to sneakily disable it for them when visiting
Yes. Motion smoothing. It's like kerning or the Wilhelm scream. Once you notice it, you'll hate it.
It makes the slow panning forests and splashy paint videos in Currys look nice, but it makes movies and TV shows look terrible.
Eh, I've been adding it on purpose to technical and astronomy documentations during transcoding for my library. 23.whatever fps NTSC pulldown is just choppy.
Yes
Nvidia calls it DLSS and pretends its new
Wait DLSS is about upscaling right? The “features” mentioned in OP’s post are about motion interpolation that makes the video seem to be playing at higher fps than the standard 24fps used in movies and shows.
Because names mean nothing Nvidia has also labeled their frame generation as "DLSS".
It allows more resolution by cutting the fps. Fake frames are inserted into the gaps to get the fps back.
That's frame generation, not dlss. DLSS renders small and upscales.
It's both. Nvidia just started calling everything DLSS, no matter how accurately it matches the actual term.
Image upscaling? DLSS. Frame generation? DLSS. Ray reconstruction? DLSS. Image downscaling? Surprisingly, also DLSS.
What you're thinking of is "DLSS Super Resolution." The other commenters are right, nVidia insists on calling all of their various upscaling schemes "DLSS" regardless of whether they're image resolution interpolation or frame interpolation. Apparently just to be annoying.
There is a marginally handy chart on their website:
All of it is annoying and terrible regardless of what it's called, though.
It is all called "bullshitted pixels" and I'm having none of it.
Its simply "visual noise" that tricks the viewer into thinking they are getting more of something than they are. Its a cheap inconsistent filler. Its nvidia not admitting they hit a technical wall and needing a way to force new inferior products onto the market to satisfy sales.
DLSS Frame Generation actually uses the game's analytic motion vectors though instead of trying to estimate them (well, really it does both) so it is a whole lot more accurate. It's also using a fairly large AI model for the estimation, in comparison to TVs probably just doing basic optical flow or something.
If it's actually good though depends on if you care about latency and if you can notice the visual artifacts in the game you're using it for.
Yeah, but only PC owners can have it so they think it's good.
Shouldn't it be more like Motion Blur?
Motion blur is consistent and reproducible using math. The other isn't. Something that cannot produce consistent results and is sold as a solution does have a name though: snake oil.
what is the actual usecase of this interpolation feature? it should require capable hardware, so it doesn't exist for nothing.
I think the idea is to increase motion resolution.
On a sample-and-hold display, like an LCD or OLED, the image on the screen stays the same for the entire frame. When the image suddenly changes because the TV displays a new frame, our eyes need a bit of time to adjust. The result is that when there is a lot of motion on screen, the image starts to look blurry.
This was not an issue on older CRT displays because they used a beam that scanned the picture. Each ‘pixel’ (CRT’s didn’t have pixels but lines, but you get the idea) would only light up for a small amount of time. Since our eyes are relatively slow we didn’t notice the flickering that much, and because it wasn’t fully lit all the time the ‘pixels’ in our eyes didn’t get saturated and could quickly adjust to the new frame.
By adding interpolated frames the image changes more often and this allows our eyes to keep up with the action. Another solution to the problem is black frame insertion, where the TV shows a black image between each frame. Again we don’t perceive this as flickering as our eyes are too slow for this, but the disadvantage is that the picture brightness seems to halve.
How much blurriness you get in motion is a function of both how fast the movement on screen is and the frame rate. Fast movement and low frame rates cause more blurriness than slow movement and high frame rates.
The use-case for this feature is mainly for fast sporting events on broadcast TV, where there may be fast movements (e.g. a soccer ball) combined with the low frame rate of broadcast TV (30 or 25 fps depending on where you are).
I suspect it's also meant to mitigate the modern fascination with buying TVs that are too big, and sitting far too close to them all the time. If your soccer ball example involves the ball being in one position on this frame, and literally six inches away in real distance on the surface of the screen on the next, and this is happening all the time, people will get fatigued and cranky watching it for extended periods.
Unless you’re Elon Musk rich, it’s pretty much impossible to buy a TV that is too big.
I own a 77” TV and the optimal viewing distance for that is 2.7 meters for a THX recommended viewing angle of 36°. The size goes up quickly the farther you sit from the screen. If your couch is 4 meters from the screen you’re already looking at a 114” screen to get the same 36° angle.
...and we all HATE it.
What
It's the setting to disable on smart TVs for a better image. The option can do oone or more of the following: adds in-between frames, reduces noise, and upscales video. Sounds good, but the implementation is always terrible.
Is this what that uncanny "too smooth" look is on my parents TV? Whenever I'd go to visit them whatever they had on always looked like the camera motion or character movement was way too smooth to the point it was kind of unsettling.
The “soap opera” effect. Filmmakers hate this
Animators too. FFS, when you deliberately position a character to look fluid, life-like, and emphatic at a frame rate, you have to respect it, or you lose it! Adding frames willy-nilly ruins movies and animation. Don't like it? Wanna be a gamer? Well, maybe just sit tight and accept that you have to trust that the artist, idfk, knew how to do their fucking job.
Personal rant here. I hate automated interpolation. I would literally prefer it if you deep-fried my work by overcompressing it over and over to 'save space.'
Yup
It brings you gorgeous frames like this:
Aqua just looks like that.
that's just Aqua
Looks like the usual Aqua to me
This is in regard to motion smoothing which is enabled by default on modern TVs, and give the effect of a soap opera look. People think that it makes the video look better, but it's just adding fake frames to display at a higher frame rate. Not a lot of people like this: https://variety.com/2022/film/news/motion-smoothing-how-to-shut-off-1235176633/
To make matters worse, all TV brands have their own name for this feature. This post is saying that when you go home for the holidays, this is the name of the motion smoothing in the settings to turn off for a better viewing experience the way the filmmaker intends.
Oh god this must be what my parents have on their TV- I thought it looked that way bc it's 4k. A soap opera look is exactly how I described it! That's been my only exposure to new/smart TVs
So they can turn off AI enhancements on their relatives' TV.
I went to a friend’s house recently where this was enabled. I couldn’t bite my tongue for more than a few minutes before I had to bring it up. They were instantly impressed with how much better it looked lol.
To further elaborate, on LG TVs it's in the "Clarity" menu.
Thank you for not typing “TV’s”
Thank you for noticing!
I think I’m the only person I know who doesn’t mind it.
Shit, maybe I’m old and that’s what everyone else is going to look for and turn off.
perfectly valid opinion to have with no consequences...
however, I now hate you
