Appendices
The transition effects built into the V-8 include FAM (Full Additive Mix) and NAM (Non-Additive Mix). Speaking simply, FAM 
and NAM are special dissolve transitions that compare the brightness (luminance) of two images in order to determine the 
degree of compositing.
If you select “003: Fam
✽” or “005: Nam✽” which have an “✽” (asterisk) following the transition name, you’ll be able to 
use the [BPM/CONTROL] knob to change the cross point of the FAM/NAM.
At this time, the FAM/NAM cross point level will blink in the BPM display. The cross point level range is 0–100.

Dissolve transition
The transition between images takes place by simply raising or 
lowering the video level. The luminance of the composite image 
will be less in the region of the cross point.
FAM transition
The images will transition with the luminance level held steady.
NAM transition
The two images will be compared, and the pixels that have a 
higher brightness level will be shown while the images are 
switched.
