3. Click the Add Selection to Media Pane button to add the retained
scenes to your Media pane. The scenes will be named separately and
will show in your Media pane.
If detecting scenes in a large video file, a progress bar appears until all scenes
have been processed (click Cancel if you want to abort the process). You can
still manage scenes while this is in progress.
Scene detection sensitivity
You can adjust the sensitivity of MoviePlus's scene detection simply by
adjusting the Threshold slider in the Scenes dialog. An average scene
detection value is set to detect scenes but you can adjust the detection
sensitivity, resulting in a different number of scenes. Moving the slider to the
left results in fewer scenes, moving to the right results in a greater number of
detected scenes.
Trimming
With audio or video clips, both duration and playback speed come into play.
Most often, you'll want to shorten a clip without altering its playback speed—
this is usually called trimming. For example, media files seldom begin or end
exactly where you'd like; there may be extra frames at the beginning or end,
or you may want to use a short section from the middle of the file. The
solution is to trim the media file—adjusting its start and end point, called "in"
and "out" points, to include just the section of video you want.
Clips stored in your
Media pane are usually trimmed in a Trim dialog before
committing to the storyboard (or timeline). The dialog shows the clip's frame
preview and the clip's timeline (with ruler), from which trimming can be
applied.
