Description
Setting a Streaming Cue’s Playback Length
Use the Length command to set the playback length for playing back a streaming cue. This time is used to
adjust the duration of a streaming cue before it begins playing back. For instance, if a stream is recorded
too long, a shorter playback length can be given to have the stream stop playing at the proper place in the
cue. The
Length command must be issued after the cue is selected but before the corresponding Go
command is issued. For example, Cue 1 Length 5.5 Go .
If a playback length is specified that is shorter than the recorded length of the cue, then the cue will stop (or
loop, or follow, etc.) at the specified time, which will be before the recorded data in the cue is finished
playing back. If a playback length is specified that is longer than the recorded length of the cue, then there
will be a delay after the end of the recorded data before the cue will stop (or loop, or follow, etc.).
Playback times are normally expressed in seconds. By using a pound-sign (
#
) before the value allows the
playback time to be expressed in fames . A frame is 1/40th of a second and is the smallest unit of time that
streaming cues are recorded in.
