Scoring a Marker to the Playhead
For tracks set to Beats-based time format, you can score a time marker or
Final Cut Express scoring marker to the playhead, so that you can synchronize the
audio with the video. Scoring a marker to the playhead adjusts the tempo so that the
required number of beats exactly fills the amount of time between the last tempo
change and the marker’s position in the Time ruler.
When you score a marker to the playhead, a set of special envelope points is created in the
project’s tempo envelope, from the previous envelope point (or the beginning of the
tempo envelope, if no previous envelope point exists) to the position of the marker. These
special envelope points are locked and cannot be moved (but can be deleted). The locked
envelope points, and the segment of the tempo envelope between them, appear red.
The tempo change created when you score a marker to the playhead is always
instantaneous; that is, the tempo changes from the previous tempo immediately, without
ramping. The distance between the two envelope points determines whether the
resulting tempo change can be heard easily. If the resulting change in tempo sounds too
abrupt, you can edit the tempo envelope to make the tempo change less noticeable.
To score a marker to the playhead:
1 Select the marker’s handle at the top of the Timeline, above the Time ruler.
Click the marker handle at
the top of the Timeline.
