A CAMREC file is a recording of live events on a computer screen captured by Camtasia (version 8.3 and earlier). It is similar to a screenshot, but is a video recording that may include both video and audio, instead of a still image. CAMREC files are often used for creating program demos, computer training videos, and other types of presentations.

The CAMREC file is used to store the raw recording of a actions on a computer screen. It does not store edits to the recording. Any modifications made to a recording are stored in the .CAMPROJ project file. The .camrec extension is only used by the Windows version of Camtasia, called Camtasia Studio. Camtasia for Mac uses the .CMREC extension for camera recordings. However, CAMREC files were replaced by .TREC files with the release of Camtasia 8.4.
