CMREC, Camtasia Screen Recording (.cmrec)
The CMREC Video file format
The screen capture program Camtasia for Apple Mac computers creates recording which is saved with the CMREC file extension. They function like screenshots but actually capture video and audio data from the user’s desktop. CMREC files are used to create screen recordings for YouTube videos, computer training, software demos, and more. The format has been replaced by the TREC format by now.
Technical details of CMREC files
CMREC files contain the raw video footage on whatever is happening on the computer during a recording session, including audio from the computer or even an external microphone. The Camtasia software also supports video editing. These changes, however, are not saved in the CMREC file directly, but in a separate file that uses the CMPROJ file extension. Camtasia Studio is the name of the software available for Windows computers. Instead of CMREC, however, this program produces CAMREC files. With Camtasia version 2.8 (or Camtasia Studio version 8.4 for Windows), both file extensions were retired and replaced by the uniform TREC file format.
