I chose this frame with some very high settings. I think it shows how well it works in choosing noise over detail. The fine strands of hair stay pretty much intact after the denoising. Also, the detail in the soldier's uniform in the background seems to have weathered the eraser well too.

BTW, I've found that enabling temporal frames with this setup doesn't always do much. The most important thing it seems is to have enough noise samples to get a complete "picture" of all the noise contained in the picture. I think I could add at least 2 more noise sampling areas to the script without interfering with subtitle areas.
