After installing the package, I saw that the values are initialized at R7 = 0, R8 = 2. Sharpness is initialized to 2. As soon as I changed R7 to 1, it worked perfectly. This also yielded a perfect image quality (at some settings there was weird noise patterns). >>From 34..50 I could reproduce the bug again. Also when I raised the sharpness to the max level of 3, the bug appeared again. So thank you again for your solution and my kudos again. Awesome! Also, svv is a really neat tool, I'll surely use that in the future. Best regards, Joe
