Camtasia Studio

TechSmith Camtasia Studio records your onscreen computer activity, PowerPoint presentations, voiceovers, webcam video, and any additional actions performed on a computer.

It also enables adding audio annotations, inserting various types of visual callouts, and further editing of presentations. The resulting "screencast" can be saved in various formats and sizes for online delivery.

Visit the Texas A&M Software Center to download Camtasia Studio (and Snagit) for a one-time cost of only $18.
