Control of VTRs, Extended VTRs, and Disk Recorders
When executing the timeline using a disk recorder, also take note of the
following points.
• Set the keyframe duration to at least 30 frames.
• From pressing the [RUN] button to the time when the effect actually starts
execution may take around one second.
In order that pressing the [RUN] button after [REWIND] make the effect
start execution as soon as possible, set cueing up of the file for operation as
rewind operation
1)
. In the first keyframe
2)
to be executed with [RUN], for
the cued-up file, do not set the start point, but set only the start command.
1) If the setting when the [REWIND] button is pressed is for the first keyframe to be executed,
then the first keyframe is executed, and otherwise the setting for the Rewind Action is carried
out.
2) If the setting when the [REWIND] button is pressed is for the first keyframe to be executed,
then the second keyframe is executed, and otherwise the first keyframe is executed.
• To execute an effect, be sure to carry out a Rewind.
For example, when the start command only is set for a keyframe, playback
starts from the current position, in the same way as with a VTR (no automatic
cue-up).
• During file playback, to play the next keyframe at variable speed, for the next
keyframe set variable speed only, and do not set the start point (see figure
below).
Example: When the recorded clip for keyframe 1 has a duration of 15 frames
30 frames
15 frames
: Interval for which clip is recorded
: Interval in which still frame is displayed
In this example, when keyframe 1 is executed, the first 15 frames consist of clip
playback and the remaining 15 frames show the 15th frame as a still image.
