Changing the Start Time of a Sound on the Playlist
-
The start time of a sound on the Playlist Editor can be adjusted using the Start Time command.
-
In a sequential (or "real time") Playlist, the Start times are automatically calculated each time an item is added to the Playlist. The sounds on the Playlist play one at a time, with no time gap between consecutive sounds. For a sequential playlist, the Change Time command can be used to add a gap of time between a sound and the previous sound.
-
For a SMPTE Playlist, the Change time command can be used to set or adjust the SMPTE time that will fire the sounds on the Playlist.
-
To change the Start times, highlight the sound you want to change on the Playlist, and then select the Start Time command from the Edit menu, or double click on the sound. A Change Time Dialog Box will appear (Figure 3-3) in which you can change the Start time by either typing in new values, or by clicking on the up/down buttons by each number. After you have selected the Start time that you want, set it into the Playlist by clicking on the Set button, then the Close button.
The Change Time Dialog Box
-
The Change Time Dialog Box can be used for marking SMPTE timecodes "on-the-fly". To do this, click on the Live button. The numbers in the box will now reflect the time display in the bottom right-hand corner of the Playlist window. Then start the SMPTE time source (such as a video tape). When you pass times that you want a sound to be fired, click on the Mark button in the Dialog Box. Each time that you click on the Mark button, a blank line will be added to the Playlist, with the timecode that was displayed at the moment you hit the Mark button. You can later use the Replace function to assign sounds to these times on the Playlist.
-
The Reset button in the Change Time Dialog box changes the time of a sound so that it plays immediately after the end of the previous sound.
-
Sounds in the Playlist will not play properly if the sounds are allowed to overlap in time.
