AV1 has tunable FGS levels, and to my eye they went very slightly higher than they should have (though there are tradeoffs; at some bitrates the blurring+renoising is so much better than the other visual artifacts you will otherwise get, that you do want it that high). A few things to note: - still-frames are also a mediocre way to evaluate video quality. - a theoretically perfect[1] noise-removal filter will always look less detailed than the original source, since your brain/eye system will invent more detail for a noisy image than for a blurry image. 1: By which I mean a filter that preserves 100% of the non-grain detail present, not one that magically recovers detail lost due to noise.
