Videos are one of the most powerful ways to communicate with viewers, and many times the best way to explain something on your computer is to show it in action.
You can make your videos incredibly effective by adding zoom, pan, and tilt features that focus viewer's attention to specific parts of the video.
I've even taken a single powerpoint slide covering the technical architecture of a complex software application, and used zoom and tilt techniques to keep viewers engaged and attentive for the duration of a 5 minute video of that single slide.
Here's how you can add zoom, pan, and tilt to your videos:
You'll need a copy of Camtasia Studio 6.0 or later, and they have a 30-day trial you can download that's fully-featured.
Open Camtasia and click the option to Record the Screen in the Welcome screen. Open your favorite software program and walk through a feature you'd like to demonstrate.
Save the video and then advance to the section in the video where you'd like to add a zoom or tilt effect. I find that any section that I'm verbally describing for more than 5 to 10 seconds makes a good candidate for a zoom and tilt effect.
Click "Zoom-n-Pan" from the Edit menu and shrink the green viewing rectangle to a smaller area of the preview screen. This will create a zoom and pan effect and you can preview it before saving your changes.
