Editing your show

Basic editing

Soundslides offers two different ways to time images in your slide show, depending on the needs of your particular presentation.

  • Auto-spaced timing
  • Precise timing

What's the difference in the two timing methods?

Use auto-spaced timing when you want every image in the show to have the same amount of time on the screen.

Use precise timing when you want to control exactly where an image appears in time. If you've used previous versions of Soundslides, then you've always used precise timing.

Auto-spaced timing

To use auto-spaced timing, adjust the secs per image slider on the right side of the edit window.

As you adjust the time, the application will update the slide show preview, and tell you how many images will fit on your timeline.

Use case for auto-spaced timing

Jon has a piece of music he knows his client will love, but he's not sure how many of his 60 images he want's to use, or how long each image should appear. With auto-spacing, he can adjust the time-per-image slider and get a sense of what speed works best for his show. Then he puts his images in order and he's done. Auto-spacing does all the calculations for him, and helps him know how best to edit down his images.

Adjusting transition type with auto-spaced timing

You can choose a transition preset at this time as well. Choose between:

  • Crossfade - Fast, Medium and Slow
  • Straight-cut (no transition)
  • Fade out/Fade in - Fast, Medium and Slow

If you need more control over transition types or need to control transitions for individual slides, open your show in the Timeline Editor. See additional information below.

Timeline Editor

The Timeline Editor is the main interface for precise-timed slide shows. If you've previous Soundslides versions, the Timeline Editor should look familiar.

The Timeline Editor

To launch your show in the Timeline Editor:

  1. Click the "Edit" button for your show on the show list page.
  2. Click "Open in Timeline Editor".

Your slide show will then open in the Timeline Editor. To exit out of the editor, click "Return to Show Details" in the lower left.

Precise timing

While the Timeline Editor initially spaces your images out evenly, you can easily modify where your image appears on the timeline.

Dragging along the timeline

Drag-and-drop the time position handles, or drag-and-drop the timeline thumbnails themselves.

Use case for precise timing

Jen has recorded an interview with a well-known artist, and has photographs of the artist's works. Jen wants each of the images to appear at precisely the moment they're being discussed in the audio track. With precise timing, Jen uses the Timeline Editor to arrange the images, then carefully positions the images' in points to appear at the correct moment in her audio track.


Use the Timeline Editor's grid pane to swap images in the timeline. Swapping an image replaces one image with another.

To move and image, click and drag on the image and position it over another image.

From the grid, you can also access additional image actions via right-clicking on the image.

Grid right-clicking actions

Right-click (or control-click) on the image to open up additional options.

Project Inspector

The project inspector is available via the right side of the main control bar in the Timeline Editor.

From this dialog box, you can set your show's transition type and speed. These settings are applied to the entire show.

Item Inspector

The item inspector is available via the right side of the main control bar in the Timeline Editor.

From this dialog box, you can set each image's transition type and speed. These settings only apply to the image being inspected. You can also set the image to use the show's project-level settings.

The Timeline Editor's Libary pane is where you can view images that have been imported into your show, but are not currently on your show's timeline. You can right-click (or control-click) on Libary images for additional options.

You can also import new images from the Library pane.


Overlays are text that appear over your slide show. Currently, Soundslides enables you to create a lower third overlay (example appearing at 0:07).

What is a lower third?

Wikipedia defines lower thirds this way:

In the television industry (especially in North America), lower thirds refers to graphics that take up the lower area of the screen, though not necessarily the entire lower third portion of the screen as the name suggests. Lower thirds are often called "supers" in the U.S. and "name straps" in the U.K.

Typically, lower thirds in audio slide shows are used to quickly identify the person speaking in the audio.

To create an overlay:

  1. Open your slide show for editing in the Timeline Editor.
  2. Click on the "Overlay" button to bring up the Overlay editing pane.
  3. Click "Add New Overlay"

You can then click in the text boxes under "title" and "secondary line" to edit the text.

The "in point" text box is the timeline position (in seconds) when the lower third first appears. The "duration" text box is the amount of time (in seconds) that the lower third will appear. You can click in either text box to change when and for how long a lower third appears.

When editing is complete, hit the Save button.
