From what I remember from my testing, disabling intra smoothing helped retain grain and other similar fine details like skin texture. The comparison would have been better with a picture of the source frame and not all just compressed frames. Tests are done with Tears of steal uncompressed 4k source downscaled to 1080p encoded with x265 v3.0+14 2pass preset slow. While not visable in sample, some areas display blocky tendencies simulair to an comparable x264 encode.
No-sao, deblock -1,-1, no-strong-intra-smoothing: Most detail restored, blurry areas from the default is back. No-sao, deblock -1,-1: Most detail restored, most of the blurry areas are gone. No-sao: Most detail restored, some areas are still blurry Have you done tests or is this somthing that just sounds like it should be befinitial so it's just assumed that it it is? Or maybe its only better at higher bitrate?ĭefault: A clear loss in detail, some areas are blurry.
So my question is why I see a lot of people using it. I've been doing some tests with common settings that I see people use arround here for detail retention, and since there is no good tune preset for this, it seems to differ a bit what settings should be used as an substitute for an tune film preset.įor my medium bitrate test (1080p 6Mbps) I found that no-strong-intra-smoothing actually only displayed negative effects.
