MediaSpace includes a basic video editor that allows you to trim and clip your videos. The editing tool is provided to trim the start and end of a recording.

If you need to do more elaborate video editing, you will need to use an external video editing application. You can download your own source recordings if you need to do real editing to your videos.

Carleton does not currently support external video editing tools. However, a few unsupported options are:

Google Video Editor (Free web-based video editor, requires Google Account)

iMovie (Free for Mac users) (Free web-based video editor)

Lightworks (Free, open-source, professional video editor)

Kaltura’s Video Editor

NOTE: It is always a good idea to use the “Save a Copy” button when editing your videos so that you keep your original version as a backup. Any changes you make and save by clicking on the “Save” button are permanent and replace your original video.
