next keyframe. A change of state in a keyer is required for a transition to occur when the
effect runs.
The transition rules have one subtle limitation. The next transition element buttons are an
interlocked group. All these buttons cannot be turned off simultaneously (at least one
element is always selected). This means you cannot uses these buttons to prevent any
transition from occurring when all the elements are in use. To workaround this special case,
add another keyframe to the effect to transition the keys with a one field transition (which
is the same as a cut).
Return to Normal Technique
A useful technique to use when building effects for use on-air is to first establish a normal
switcher state for the particular show. This normal state could, for example, have only the
Bkgd next transition element selected, a Mix transition type, all keyers off, and one second
transition durations. This normal state permits immediate cuts or dissolves to and from any
element, probably the most common requirements during a live show.
Running the effect departs from the normal state to do whatever is required. When the
effect comes to the end of its run, the next to last keyframe controls the transition that
occurs at the end of the effect. The last keyframe has no following keyframe and so does
not transition, and that keyframe effectively has no duration. You can set the next transition
elements in this last keyframe to the normal state without fear of causing unanticipated
transitions. This return to normal technique permits completely controllable seamless shifts
between your effect recalls and runs and your live switching.
When building effects for the show, take care that the beginning and ending of every effect
works well with the normal state. You also may wish to apply a Source Hold to the first
keyframe to ensure the last source selected remains unchanged going into the effect.
About Source Holds in Effects
During E-MEM recalls and effect runs sources can be programmed to change. Sometimes
this is not desired, as an effect may be designed to run on the currently selected sources,
not the particular sources used when the effect was built. Holds can be programmed into
an effect with the Source Holds menu to prevent sources from changing when that effect is
recalled. This form of hold is keyframeable, and so can be applied to specific portions of an
effect.
