Postprocessing like a tv (fake framerate)

[kght22]

this is a pretty stupid question, and one that i should know the answer to or at least be able to think of a way to search this site to find it (it has surely been asked) but i am at a loss. 

 

i am certain that many of you have noticed ridiculously smooth framerates out of higher end tvs that are only getting a 24-30fps input from the source. post processing to interpret in between the frames. (like several somewhat old at this point tvs that claim crap like 200hz in a special mode that isn't an actual mode or whatever, just the monitor upscaling the framerate in a similar way that you would upscale resolution.

 

am i completely missing something, shouldn't a computer be fully capable of emulating such a feature over hdmi given enough processing power on the computer side. is there some software out there to enable this or some feature i am not aware of, because i pay pretty close attention and have for decades and i have never heard it mentioned. the apparently smoother framerate is real on those screens, and while it is internal to the screen i would expect or hope that some attempt could be made to match the 60hz of most other screens just using software on the computer. 

 

i clearly am full of ignorance on this issue, so curiosity please? (and yeah, i tried google, i don't know the right question i think)

oh, and i would like to point out that i am not talking about this in reference to gaming, that would to start with be insane because latency is a thing. i am talking about it for video.

what you are describing sounds like doubling frames which is what g sync and free sync does when your fps drops too low

i am only talking about what a normal high end tv does in making low framerate video smoother (24fps video looking more similar to 60fps or more, notably more similar not the same, and definitely visibly smoother) there is no variance in framerate here, my computer isn't going to drop or lag frames playing back 8k at 24fps let alone at the 1080p that i use, and the source material is usually more like 30 because youtube (not because youtube uses it even though they do, but because most video on computer is 30fps. high end tvs insert between frames in the gaps that are interpretations based on the frame in front and the frame behind. adds latency (post processing) but that is practically meaningless in video playback so long as the audio remains synced. get what i am talking about. it isn't doubling the framerate (in a manner of speaking on a 60hz monitor 30fps video already essentially does that) but much more like a 1080p monitor that is able to full screen display 720p video without mangling it.

I thought gSync and FreeSync lowered the framerate of the monitor to match the output from the gpu, preventing any kind of tearing at low frames.

I'd like to note that even if a movie is 24fps your tv will still display the 60hz it's designed to do, it'll just double up some of the frames

this is not what elijah said, blah.

there isn't any tearing, and you are missing what i am saying. i suspect you have never seen a decent tv playing 24 or 30 fps playback with it's postprocessing on, there is a very obvious smoothness diference between that high end tv and any computer monitor, even a really high refresh rate computer monitor. it is intepreting the frames between the frames just like resolution scaling is interpreting the pixesls between the pixels. this has nothing to do with gaming or variable framerates, videos only use a consistent framerate. this is literally about a feature in higher end tvs that makes video playback VERY visibly appear smoother, and if there is some sort of way to have a computer do it and just feed it over hdmi to a dumb tv.

you seem completely unaware of the frame smoothing that higher end tvs use that literally make the framerate look higher than the source material.

I have a 4k Curved LG tv at home  The picture does look better but I've never really seen it look smoother

I think the TV's just running a high refresh rate and not doing much else

do you remember the option that you have to change for playing games at a lower latency?

No I've never actually played games on it, I know it can run at 200Hz I've never looked into it though, I could when I'm home if you'd like. I know that it sharpens images that are lower then 4k (Nearly Everything) That + High Framerate could make it appear much smoother

that is called post processing, your graphics card uses it too for other things, like fxaa or dsr (dynamic super resolution). it takes time, causing latency. i am asking if you could do that on your computer instead of using a smart monitor that has it built in. it seems like something that the power of a pc would easily be able to handle. i would like to watch videos on my computer with nice smooth looking (key word there, looking) framerates, like a high end monitor that is using it's post processing tech.

Looks like you got yourself a Fast as Possible  https://www.youtube.com/watch?v=KTY9uDD0x14

i noticed that too, although it has been a week or two since that happened. somethng i did notice though was that software should be able to do the same effects that you get in a monitor on a pc. and we don't get those options. it is all software and processing, and we have processing to spare.

i am one of the folk who likes the smoothing. i love the so called "soap opera" quality because it is quite simply smoother looking, and looks more like a person moving in front of me than watching a recording. yeah, it is false, i knew that from the start. i want it.

in other words i don't care how much hardware is put into the tv, even a moderate gaming pc has more power and could just output a signal with the correction built in without breaking a sweat if anyone thought that pc enthusiasts were interested

Yeah I would probably use something like that as I enjoy high frame videos, it's possible that our pc's don't have the correct hardware to do the job fast enough, while your gpu is probably great, it might not be the right thing required for this job.
