The Presto Timeline
The timeline shows the tracks and clips in your sequence in a
manner similar to Final Cut Pro and Premiere Pro.
As with FCP, video tracks are grouped together in the
upper section of tracks, listed upwards from V1. Audio tracks are
grouped together in the lower section of tracks, listed downwards from A1. The
height of the audio tracks section is fixed. The height of the video
tracks section adjusts as you adjust the horizontal splitter above the
timeline, or as you adjust the overall window size.
The position of the playhead is shown in the upper left of
the timeline in units of: hours:minutes:seconds;frames.

The timeline shows the audio and video clips for each
track, and the layout sequence
Editing Operations
The timeline supports a number of editing operations:
- Move and scrub the playhead by clicking and dragging on the ruler.
- Zoom in with the "+" button
on the lower left. Zoom out with the "–" button. Zoom-to-fit with the Fit button.
- The icons above the ruler show the layout sequence, and
the green bar below each icon shows the extent of the timeline that the
layout applies to.
- You can edit the in or
out point of any clip by dragging one end of the clip. Where there is no gap
between clips, you can drag the clip transition point (which simultaneously
adjusts the out point of the left clip and in point of the right clip). This
is especially useful for editing slide transition timing.
- The View menu lists additional
timeline commands and their keyboard shortcuts:

Notes about the timeline
- You cannot move or delete clips that are not on the slide track; see here for help on creating
your sequence in FCP so that it is ready for use in Presto.
- You cannot edit Mask track clips, because these are
automatically managed by Presto to match the layout timing.
- You can move or delete selected slide clips. Click on a
clip to select it. Shift click on another clip on the same track to extend the
selection. You can only select multiple clips that are on the same
track, and only contiguous selections are supported.
- For manual slide
placement, select one or more slides in the slide viewer and drag them to
the slide track. Hold down Option while dragging for fit-to-fill.
- The small icons at the head of each track enable or disable the
track. A darker icon indicates a disabled track that will not be
included in playback. Lighter icons indicate enabled tracks.
Click the icon to change its enabled state. NOTE: It is recommended that
only one set (stereo pair) of audio tracks be enabled for playback.
Menu of additional options
Right click on the timeline for a menu of additional options.

- Apply Default Layout: Re-applies the
default layout to your presentation.
- Refresh Layout: Refreshes the layout
key frames that are generated based on the layout sequence. Try this if
your layout appears messed up.
- Show Layout Key Frames: Shows the
location of the layout keyframes. These become motion keyframes in the
sequence exported to Final Cut Pro.
- Exclude From Processing: When
checked, excludes the selected presenter or screen clip(s) from Presto's
automatic processing. This is useful when there are sections of the
video that it is not appropriate or necessary to apply the
processing to, but you need to identify these sections and split them
into separate clips prior to exporting the project from FCP to Presto.
