Ops 7–32 • Keying Vision Operator’s Manual (v12.0 MD)
Key Trails
The XFX Dual Border Generator option allows you to add trail effects to any key type on the
switcher. Trail effects include Soft, Hard, Key, and Key Smear trails. Soft and Hard trails apply to
the video in the key, and Key and Key Smear trails apply to the key itself. In the case of a shaped
key, the trails are only visible within the key itself if a Soft or Hard Trail is used. Select a Key or
Key Smear Trail if you need the trails to appear outside of the key.
Important — All Key Trails cause a one (1) frame delay in the keyer that the trails are turned
on for.
Note — You cannot apply a Key Trail and an XFX Border to the same key. The XFX Border
turns off automatically when you apply a Key Trail.
Soft Trails
Soft Trails applies a transparency to all moving objects in the shot with a decaying image behind
the motion (Figure 7.9). Soft Trails are best applied to a stationary background with moving
elements in the foreground.
