   Buttons in centre column	Enable master luminance for tolerance and softness and minimum/maximum luminance levels for tolerance and softness. F1=Master luminance for tolerance F2=Minimum/maximum for luminance for tolerance F4=Master luminance for softness F5=Minimum/maximum luminance for softness
   Knobs at top right	Modify key edges and remove stray pixels from a key. Reduce image grain and noise, and keep edges intact prior to keyer input processing. Knob 4=Cleanup/Soften toggle Knob 5=Shrink Knob 6=Blur
   Upper right buttons	Press F1 to enable cleanup (Key-out filter), shrink, and blur. Press F4 to enable soften (Key-in filter). F1=Cleanup F2=Shrink F3=Blur F4=Soften Single-press F2 and F3 to reset shrink and blur, respectively. Double-press F1 and F4 to reset cleanup and soften, respectively.
