VTR/Disk Recorder Timeline

Note

When executing a VTR/disk recorder timeline using a disk recorder, note the following points.

•When carrying out keyframe settings, be sure to recall the file for operation first.

•Set the keyframe duration to at least 30 frames.

•If the duration of the 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 of the last frame of the clip (see figure below).

Example: When the recorded clip for keyframe 1 has a duration of 15 frames

30 frames 30 frames

15 frames 15 frames

KF1

KF2

KF3

: 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.

•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).
