To Check Media Out in Final Cut Server, first browse to the clip you want to check out and then while that clip is highlighted, click on the icon below that looks like a pencil.
Now you will be prompted for where on your system you would like to save the file to. Select the location and click Save and the file will download to your computer. While other users can see it, when a file is checked out no one else will be able to use the file. Once you’re done with it, check it back in by browsing to the clip in Final Cut Server and clicking on the pencil icon beside the clip’s thumbnail.
