Understanding Animation and Sound in Presentations
In modern presentation software, adding animations and sound effects is a powerful way to make your slides more engaging and effective. These features help control the flow of information, emphasize key points, and hold the audience’s attention. This section covers the core concepts of animating objects and integrating audio, as well as the utility of rehearsal timings.
Key Concepts Explained
1. Animation Effects
Animation refers to the movement of text, pictures, or other objects on a slide. Presentation software typically categorizes animations into four main types:
- Entrance: These effects control how an object appears on the slide. Examples include Fade, Fly In, and Wipe.
- Emphasis: These effects draw attention to an object that is already on the slide. Examples include Pulse, Spin, and Grow/Shrink.
- Exit: These effects control how an object leaves the slide. Examples include Fade Out, Fly Out, and Disappear.
- Motion Paths: These effects move an object along a predefined or custom-drawn path on the slide, offering more complex movement control.
You can apply multiple animations to a single object and control their sequence, timing, and trigger (e.g., On Click, With Previous, After Previous).
2. Adding Sound Effects
Sound can be added to a presentation in two primary ways: as part of an animation or as a standalone audio clip that plays across slides. When linked to an animation, a sound effect plays concurrently with the visual effect. You can use built-in sounds (like ‘Applause’ or ‘Click’) or insert your own audio files (e.g., .mp3, .wav).
3. Rehearsal Timings
The ‘Rehearse Timings’ feature is a crucial tool for creating self-running presentations, such as those used at kiosks or in unattended displays. This feature allows you to record the amount of time you spend on each slide and for each animation while you practice your presentation. The software saves these timings, and when you play the slideshow, it will automatically advance through slides and animations based on your recorded pace, without needing a presenter to click through.
Animation and Sound Options Summary
| Feature | Purpose | Common Options |
|---|---|---|
| Animation Pane | To view, order, and modify all animation effects on a slide. | Re-order effects, change triggers, adjust duration. |
| Effect Options | To customize a selected animation effect. | Direction (e.g., From Left), Sound, after-animation color change. |
| Audio Tools | To manage inserted audio clips. | Trim audio, fade in/out, set volume, play across slides. |
| Slide Transition | To animate the change from one slide to the next. | Push, Fade, Cover. Can also have associated sound effects. |
Quick Revision Points
- Animations are visual effects applied to objects on a slide.
- There are four types of animations: Entrance, Emphasis, Exit, and Motion Paths.
- The Animation Pane is essential for managing multiple animations on a single slide.
- Sound can be added to an animation or as a background audio clip.
- ‘Rehearse Timings’ records the duration for each slide and animation to create a self-running slideshow.
- Transitions are effects applied to the slide itself, not the objects on it.
Extra Practice Questions
- Describe a scenario where using an ‘Exit’ animation would be more effective than simply changing to the next slide.
- How would you set up an audio file to play continuously throughout your entire presentation?
- What is the main difference between an ‘Emphasis’ animation and an ‘Entrance’ animation?
- Why is it important to use the ‘Rehearse Timings’ feature for an automated kiosk presentation?
- Explain the function of the ‘With Previous’ and ‘After Previous’ start options in the Animation Pane.
