Introduction to the DVE

asb=bÑÑÉÅí=aìê~íáçåë

The following rules apply to DVE effect durations:

•Each switcher bank and M/E has its own unique transition rate and curve, as controlled on the Transition Menu. This rate governs how fast (or slow) you can mix, wipe and key the various layers when AUTO TRAN is pressed.

•The M/E transition rate and curve also applies to the DVE:

~The transition rate governs the effect duration for dual keyframe DVE effects — that is, how fast (or slow) keyframe 1’s parameters transition to keyframe 2’s parameters.

~The transition curve determines the type of motion path that the effect obeys (linear, S-curve, logarithm or exponent).

•To change the DVE effect duration, change the M/E transition rate.

•To change the DVE motion path, change the curve.

•By providing one rate and one curve for all transitioning parameters on the M/E, there are no conflicts when you pause and resume transitions using AUTO TRAN, and no conflicts when you use the T-Barfor manual transitions.

•If an M/E transition involves an effect (e.g., mix or wipe) plus a DVE effect, both always start and end simultaneously.

The term “morph” essentially means to “transform.” The FSN Series DVE enables you to smoothly morph between a wide variety of parameters, from keyframe to keyframe.

The following list outlines morphing parameters.

•PIP position and size

•Source pan and zoom

•Mask

•Border width, color and edge type (e.g., hard, soft, halo, inside halo, outside halo)

•Shadow size and position

•Shadow edge width, luminance and opacity

•Image brightness, contrast, hue and saturation

•Monochrome

All other parameters do not morph. Instead, the system “cuts” to the requested effect when the keyframe containing those parameters is reached in a dual keyframe effect.
