In Camtasia Recorder, users can start and stop recording with shortcuts at any time, at which point the recording is halted and Camtasia Recorder can render the input that has been captured into the TREC format. The TREC file can be saved to disk or directly imported into the Camtasia component for editing. Camtasia Recorder allows audio (and webcam) recording while screen recording is in progress, so the presenter can capture live narration during a tutorial or presentation. Camtasia also supports dubbing in other audio tracks or voiceover during post-capture editing. Windows users may also install an add-in for Microsoft PowerPoint that will allow them to initiate recording of a presentation from within PowerPoint itself.

In Camtasia (also known as the Editor), the Media Bin is where media (screen recordings, voiceovers.) for the current project are stored. The Library stores reusable media across multiple projects. On the Timeline, overlays of various types like annotations may be added, including user-defined settings, such as when and how to display the cursor and pan-and-zoom effects such as the Ken Burns effect. In order to provide localized versions of the produced videos, subtitles can be added with the captioning feature.

The Editor allows import of various types of video, audio and image files including MP4, AVI, MP3, WAV, PNG, JPEG and other formats into the Camtasia proprietary TREC format, which is readable and editable by Camtasia. The TREC file format (using TSC2 Codec) is a single container for various multimedia objects including video clips, images, screen captures and audio/video effects. On computers where Camtasia is not installed, you can download the TSC2 Codec for free to play TREC files.
