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.
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
In the first keyframe
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).
playback
a) At keyframe 2, set variable speed only, and do not set the start
point.
• When using a disk recorder with the VTR/disk recorder
timeline, if you carry out the following sequence of
operations, the system may freeze on the frame of the
start point.
Press the [RUN] button to play to a point close to the
end of a file, stop playback, then press the [RUN]
button once more.
In such cases, first recall a different register, then carry
out the following sequence:
Recall the original register again, press the [REWIND]
button, then press the [RUN] button.
• Some operating limitations apply when the video disk
communications protocol is used. These are explained
with reference to the following figure, which illustrates
creation of a timeline that plays from the video of file A
to the video of file B.
