i think i understand how the reference frame blend percent is working, but i'm a little unclear how it's being used.
does the motion detection system compare the current composited frame to the previous composited frame or does it compare the current live (single) frame to a composited reference frame? it seems like comparing two composited frames would be odd since the current reference frame is made up largely of the previous one. but i don't understand why the default blend % is less for indoors compared to outdoors. i would expect outdoors would benefit from longer blends (lower %) compared to indoors, so i'm questioning if i'm understanding things at all.
also, "no blending" is logically the 100% option, yeah? the way it shows up in the menus implies it's the 0% option. but again, maybe i've totally got it backwards. every time i think i get it, i find something that makes me think otherwise.
