| I'm back for more. Pardon the ignorance, I'm somewhat new to scripting and I'm having difficulty figuring out what is being asked for in an example like this: Usage FixVHSOversharp(clip clip, int brightness_change, int detection_width, int offset) FixVHSOversharpL(clip clip, int brightness_change, int detection_width, int offset) brightness_change: The minimum brightness change to examine for the oversharp problem. (If there isn't an oversharp problem it won't try to fix anything.) I usually set this to 40. detection_width: The width in pixels of the oversharp scanning window. I usually set this value to 12 or 14. Offset: The position in pixels of the working pixel. I usually set this to 8 (or detection_width-4). What is being asked for, specifically in the expression " clip clip," and why is "clip" repeated? And is the comma then integral to the script ? Those of you familiar with this filter, what is the author referring to when referencing the "working pixel"? Any and all comments are welcomed. Thanks much, Matthew |
