    SG Scene Detect is a NOP -- how do the sensitivity controls work?

    SLTyPete Community Member

      I have a four minute clip that produces a complete flatline in SG Scene Detect.

       

      My guess is that it may have something to do with the content: it is 8mm film partially digitized to HD (i.e. SG/SD is part of the process) so is letterboxed  on L/R... I'm thinking maybe all that black is driving the detector crazy.

       

      In any case, NONE of the documentation I can find gives any hint at all as to what the "sensitivity" controls do. Is there a document anywhere on this?

       

      What I see for controls:

      - Large arrow (and digits) that can be moved with mouse or shift-mouse (for speed). Default value 2.0

      - If the value is changed, a blank box shows up on lower right. It appears to reset the value.

      - A small square below the line appears to signify nothing, at least for now

      - Tooltip says "Press ctrl to toggle Gang" -- so there's a set of ganged controls somehow

       

      - The normal slider range is 1.25 to 4.0

      - If I go beyond those values high or low (even negative), two extra markers show below the line, and approach from both ends simultaneously toward the small box

      - Sliding left increases the number without limit (I dragged up to 35 billion). The two lines appear to touch the box at around +130

      - Sliding right decreases the number below zero also without limit. The two lines appear to touch the box at around -130

       

      Pressing 'ctrl' may toggle a Gang but I guess I'm not a Gang Member -- I can't see where the Gang is hiding out

       

      In any case. I'd love to know what these controls do. And I'd love to actually detect a scene in my clip!

       

      Thoughts?
