If you attend my introduction to TechSmith Camtasia mini course, you learn how to use the Camtasia Recorder tool to create a software demonstration pretty early. During the recording process you will, of course, capture every click you make with your mouse. Later, in the Studio, you can elect to hide the mouse completely, or add some nifty cursor effects that can enhance the learner experience.
To add Cursor Effects, record a video using the Recorder and add it to a Camtasia Studio project. (Don't forget to also add the video to the Timeline.)
Double-click the video you added to the Timeline to move the Playhead to the beginning of the video and then Preview.
As the video plays, pay particular attention to the mouse cursor. It's moving around the screen just fine, but you can't hear or see any visual mouse clicks.
To add a click sound and visual effect, on the Timeline, double-click the video object again to move the Playhead back to the beginning of the video. Then choose Tools > Cursor Effects.
The Cursor Properties appear. From here you can hide the Mouse cursor or add effects. For instance, from the Left-click effect drop-down menu, choose Rings.
Preview the video. And just like that, Camtasia adds a nifty effect every time the mouse was clicked during the recording process. How cool is that?
You can add click sound effects to the cursor just as easily. From the Cursor effects panel (Tools > Cursor effects), click the arrow to the left of Click sound effect to expand the options. From the Left click drop-down menu, choose Mouse click.
You can click the yellow speaker icon at the right to hear the sound effect. And as with the visual effects, you can preview the video to hear the mouse click sound you just added.
