I want the same smoothing filter to be applied even when I don't fullscreen, at any scale. Windows 7 64bit, nvidia geforce 9500 GT. Firefox browser.
It all depends on the video size. If the video size is HD Big resolution size then the video should look quite good when fullscreen. But if the video size is small, when you make the video fullscreen, it will look all blurry and pixelated. I doubt there is any "Smoothing filter" unless the video is a big size, high quality video. I don't know if I'm right or wrong with this, but I noticed it as well when I watch youtube videos or just regular videos on my computer.
