Record Your Screen
To start a recording, click the Record button at the top of the tools panel. This opens the Camtasia recorder, which by default, is set to capture everything that happens on your screen.
Edit your Video
Often we record a little extra at the beginning and end of a recording. To remove the extra content, drag the end of the clip “in.” This is called trimming. If you trim too much, drag the clip back to restore your video.
Export your video
Click the Export button to view all of the export options available in Camtasia. The first option exports the project as a video file on your computer. The following options export to web services, which require you to sign in to an account.
