    The .trec files Camtasia 9 to 2026 records (Windows and Mac), .camrec files from Camtasia Studio, a zipped .cmrec bundle from Camtasia for Mac, or a .zip of several. Up to 20 recordings.

    Options
    Frame timing

    Camtasia stores a screen frame only when the screen changes. For editing, every frame is written at the recording's frame rate (Premiere, Final Cut and Resolve prefer this). For watching, the frames are kept as recorded: smaller files, converted faster.

    Mouse pointer

    Camtasia keeps the mouse pointer apart from the screen picture, so other players never show it. Draw it in where it was, with its changes of shape, or leave it out to add pointer effects in your editor (the pointer path comes as a CSV either way).

    Wide or high-resolution screens make large files. Scaling down keeps the picture sharp enough for most viewers.

    Besides the MP4 with all sound mixed in, write the microphone, system sound and other tracks as separate M4A files.

    Your files are deleted after processing.

    Open a .trec file without Camtasia

    A .trec file is what Camtasia Recorder saves: the screen, the microphone and system sound, a camera if one was on, and the cursor path. It is an MP4 container, but the screen inside uses TechSmith's own codec, so VLC, QuickTime, Windows Media Player and video editors show no picture or refuse it. Here it becomes a normal MP4 that opens anywhere.

    What you get

    • The screen recording as MP4 (H.264 video, AAC sound) at its full size, with every sound track mixed in.
    • The camera as a second MP4, when the recording has one.
    • Each sound track on its own (M4A) if you tick the option, for example to clean up the microphone separately.
    • A short preview and a still, so you can check the result first.

    Things to know

    • Camtasia records the mouse pointer as separate data, which other players ignore. The converter draws it back into the MP4, with its changes of shape.
    • Renaming .trec to .mp4 does not help: the screen video still needs TechSmith's codec.
    • If the .trec came from a Git repository and is only a few hundred bytes, it is a Git LFS pointer, not the recording: download it again from the repository's LFS storage.

    Privacy

    Results are deleted automatically after 30 minutes, or straight away with "Delete now".
