Section 4— Switcher Operations
Keyframe Operations
The switcher can store more than one switcher state (a
“keyframe”) on each enabled level in a single E-MEM register. A
series of keyframes in an E-MEM register is called an effect. Once
stored in E-MEM memory, an effect can be recalled and caused to
transition (“run”) between keyframes, either manually or
automatically.
There are two parts to this section. The Basic Editing section
describes creating, storing, and modifying keyframes in an
E-MEM effect. The Advanced Editing section describes making
changes to keyframes, keyframe timeline manipulations,
keyframe motion and path types, and making changes to entire
effects.
Setup
■ Clear the switcher (see Clearing the Switcher on page 4-4 ).
■ Select enable buttons M/E 1 and PGM PST on the E-MEM
Subpanel.
Basic Editing
This procedure will use wipes to demonstrate how keyframe
editing works. You will create a two keyframe effect, then
manipulate that effect using the keyframing editing subpanel and
the keyframe menus.
■ Learn two keyframes
■ Test the effect
■ Navigate through the effect using: REWIND, PREV
(keyframe), NEXT (keyframe), AUTO RUN, REV(erse), STOP
NEXT KF.
