Now that you've added some files to the Timeline, you'll want to synchronize them. There are two different methods for synchronization: (Note: you must be in the "File Studio" mode, not the "Preview" mode.)

Stopped Video Method

1. You can simply Drag 'n' Drop your slide files onto the "Slide 1" track of the Timeline.
2. If you would like a place the file on the timeline with a little more precision, with the video stopped (or paused) you can drag the yellow time marker to your preferred location.
3. Once you have marked the desired time, you can add a new slide by double-clicking on or right-clicking on the slide file in the library.

If you add the new slide over top of an existing slide, StreamAuthor will adjust neighboring slides on the timeline to accommodate it.

Playing Video Method

The preferred synchronization method is to play the video and add slide files "on-the-fly". This method lets you watch the video and with a simple mouse-click initiate the transition to the next slide.

1. Move the Time Marker to the start of the timeline, or to another preferred location.
2. In the Library panel, single-click the slide that you wish to add first.
3. Press the Play.
4. When you would like to add a new slide, click on the Apply button.

Add New Slides to the Timeline with the Apply Next button

With your slides sequentially organized, adding the next slide is as simple as clicking on the "Apply Next" button. Precisely when you should push the button depends on you and your presentation. Organizing your slides in sequence before starting can save you a lot of time. Otherwise, you'll constantly need to navigate through your slides, select the appropriate one and click on the "Apply" button. Sometimes this can be difficult to do well, especially if the Video file is still playing. If your slides are sequentially organized in the library you will only need to wait for the right moment and click on the "Apply Next" button.

If you find that some of your synchronization attempts were initiated too early or too late, you can modify their position on the timeline. By clicking on and dragging an existing timeline item, it maintains its original length, but modifies the times of surrounding slides. By placing the mouse cursor between two slides so that the horizontal resize (double-arrow) cursor appears, you can adjust the time for those two slides without changing other slides.
