DDR/VTR Timeline

A DDR/VTR timeline is an effect timeline for a device.
You can configure an action at a keyframe point on an
effect timeline to operate a device, such as VTRs and disk
recorders.
DDR/VTR timeline actions
You can configure the following action commands.
• Start
• Stop
• Cueup
• Variable Speed
Executing a DDR/VTR timeline will output an action
command for the target device when the keyframe point
configured with that action is reached.
Notes on DDR/VTR timelines
When controlling a disk recorder or AMP compatible
device using a DDR/VTR timeline, note the following.
• Up to eight files can be configured for a single timeline.
• To configure an effect timeline, the target file must be
loaded beforehand.
• Set the keyframe duration to at least 30 frames.
• If the duration of a recorded video clip is less than the
keyframe duration, after playback to the end of the
clip, the remainder of the keyframe duration is filled
with a still image of the last frame of the clip.
Example:
For a keyframe duration of 30 frames and keyframe 1
(KF1) clip recording time of 15 frames:
When KF1 is executed, the first 15 frames are played
back as a clip and the remaining 15 frames show the
15th frame as a still image.

• It takes about one second from pressing the [RUN]
button to the time when the effect timeline actually
starts execution.
When the [RUN] button is pressed after using the
[REWIND] button, configure the following so that the
effect timeline execution starts as soon as possible.
– Set target file cueup as the action when rewinding.
If the first keyframe is configured to be executed after
rewinding, set to the first keyframe. If the first
keyframe is configured not to be executed, set as a
rewind action.
– In the first keyframe to be executed using the [RUN]
button, do not set a start point for the cued-up file, but
set only a start action.
If the first keyframe is configured to be executed after
rewinding, set to the second keyframe. If the first
keyframe is configured not to be executed, set to the
first keyframe.
• To execute an effect timeline, first cueup using the
[REWIND] button.
Since cueup is not performed automatically, playback
starts from the current position when only the start point
is set.
• During file playback, to play the next keyframe at
variable speed, set variable speed only for the next
keyframe and do not set the start point.
Example:
For variable-speed playback at keyframe 2 (KF2):
Set variable speed only at KF2 and do not set a start
point.
Playback
• When using a disk recorder with a timeline, if you carry
out the following sequence of operations, playback may
freeze on the frame of the start point.
