How to use with videos, movies and animes?
Software works great with games but I'm not sure how to use it with videos and movies. I have a 1080P monitor. Frame Generation works, it looks smooth but I also wanna improve the image quality with scaling. I tried most settings but I just see no improvements, it looks the same to me. What am I doing wrong?

For scaling, it's generally used from one resolution to another. Therefore, if you watch a 1080p video on a 1080p monitor, the change is very little.

However, the tricky part is, LS only conceives resolution by the window size. It means that, even you open a 720p video on your 1080p monitor, in fullscreen LS will take it a 1080p video.

To do the real scaling, you have to make the window size smaller then LS will do the scaling for you. For example, if it's 720p, resize it to 720p.

Hope you understand what I mean.

You might not be able to make out the difference if your input resolution is sufficiently high, or even native. At native input-res the effect will mostly be a subtle sharpening effect at a lot of settings.

At least LS1, will supersample (upscale then downscale) your image if the input resolution matches the output/monitor resolution, or so i've been told.

If you want to test if LS's scaling is functioning properly, i suggest setting "Scaling type" to "Nvidia image scaling" and cranking the sharpness to 10. This should make it obvious.

I can definitely see the sharpness increasing, so it works. I guess the image quality won't get better though. Thanks!

The only algorithm that appears to do any kind of improving besides quality upscaling is Anime4k. Give that a try, works fine with video/movies.

This is exactly what the scaling from 1080p to 1080p does. The scaling factor becomes 1 and does nothing but only sharpening.

What does the Size option do in Anime4k scaling type?

It should affect quality, i know for a fact it increases resources used.

Hmm, have you played the latest Assassin's Creed games? Basically there you can toggle resolution scale from 1 to 1.40x for example (goes higher) and the image will not only look sharper but it also has a lot less aliasing/shimmering. I was looking for something like that.

It goes from Small to Very Large, I assume Large is the better quality here?

This is because a higher resolution scale causes the game to render more pixels/data. Or at least use a higher resolution when calculating some effects such as antialiasing. LS can't make something render more pixels/data, outside of increasing it's window size.

I see, kinda shame. would be awesome if such technology existed :D

The most convenient way is make sure your desktop resolution is higher than the video resolution. Then upscale it from windowed mode.

In other words, open the video player / browser, resize it to about 70% of screen size, scale it in LS.

idk why but in crunchyroll it goes blackscreen when scaled.

Probably DRM related, some users have suggested turning of Hardware-accelerated Scheduling can fix this.
