Effect Attributes
An individual effect may also have attached special
conditions relating to switcher or DME operation when the
effect is recalled. These conditions are called “attributes”
of the effect, and can be added when the keyframe effect is
saved or recalled.
Types of attribute
The attribute that can be attached to an effect is as follows.
Effect dissolve: The transition from the state before the
effect recall to the state at the effect start point is
carried out smoothly, by a dissolve.
Temporary attributes
When a keyframe is recalled, independently of the
attributes held in the register, you can also enable or
disable attributes. These attributes are called temporary
attributes. Temporary attributes are set when a keyframe
effect is recalled.
Effect Editing
For editing operations such as to insert, delete, or modify a
keyframe, it is necessary to stop the effect at the
corresponding point on the time axis. This is termed an
“edit point.”
You can edit either on a keyframe within the effect, or at
any point between keyframes.
Insert: Insert the current image as a keyframe. Inserting a
keyframe in an existing effect may change the duration
of the effect (see page 299).
Modify: Modify a keyframe. You can modify a single
keyframe or a range of keyframes in the effect
together.
Delete: Delete a keyframe. You can delete a single
keyframe or a range of keyframes in the effect
together.
Deleting keyframes from an effect reduces the
duration of the effect (see page 299).
After deleting a keyframe, you can reinsert the
keyframe with a paste operation.
Copy: Copy a keyframe. You can copy a single keyframe
or a range of keyframes in the effect together.
Paste: Paste the keyframe last copied or deleted anywhere
within the effect.
Pause: Set a pause on a particular keyframe, so that when
the effect is run it pauses on this keyframe. You can
make this setting on any number of keyframes. To
restart the paused effect, repeat the operation to run the
effect.
KF Loop: Execute the effect the specified number of
times through the keyframes in the specified range.
Undo an edit operation: Undo the effect of the last
operation to insert, modify, delete, or paste a
keyframe.
Duration modes
In keyframe editing, there are two duration modes; switch
between them in the utility/shotbox control block (see
page 314).
Variable duration mode: In this mode, inserting or
deleting a keyframe increases or reduces the duration.
Constant duration mode: In this mode, inserting or
deleting a keyframe does not change the duration. This
is useful for keyframe editing of an effect with a fixed
duration.
In the variable and constant duration modes, the keyframes
to which a modify operation applies, and the effect of a
paste operation are different.
Difference in keyframes to which a modify
operation applies
a) A new keyframe is inserted at the effect position.
Difference in the effect of a paste operation
Variable duration mode: The copied keyframe is
inserted at the specified position.
Constant duration mode: The copied keyframe is written
over the specified position.
Transition mode
You can use an effect created with keyframes as a DME
wipe pattern on the switcher. In this case, it is necessary to
set the transition mode (the way in which the effect
behaves) (see page 314).
Time Settings
Keyframe duration and effect duration
You can determine the execution time of an effect by
setting either the keyframe durations or the effect duration.
Keyframe duration: This is the time from the keyframe to
the next keyframe. You can set this time in the utility/
shotbox control block (see page 317).
In constant duration mode (see page 298), it is not
possible to change the keyframe duration setting.
Effect duration: This is the total execution time of the
effect, from the first keyframe to the last. You can
change this time in the utility/shotbox control block
