The default video player for Macs is QuickTime Player, which has some basic functionality to trim the start/end of any almost video file. Useful for trimming dark or empty starts to class/meeting recordings, it takes just a few moments to learn! Contact software@uiwtx.edu to learn more about other video editing options and training!


Quicktime player option to open video by right clicking
1. Locate and open the video on your computer you'd like to trim > right click the file > hover over 'Open with...' > Select 'QuickTime Player'.

Note* QuickTime Player is the default video play on all Macs, so if you haven't changed this you should be able to simply double-click the video to open it.
Edit > Trim in Mac's menu






2. Click 'Edit' > 'Trim...' in the upper left menu

Note* Alternatively, you may press the keyboard shortcut: Command+T

Drag the start and/or end of the video's timeline (as shown left) to your desired starting/ending point of the video and click the 'Trim' button when finished.

Note* You'll only be able to adjust where the video starts and ends this guide. If you're a faculty/staff, to delve deeper into video editing and a more robust toolset, visit the Available Software app in Cardinal Apps and find 'Camtasia' to learn more.
4. After you've trimmed the video, confirm the changes are correct, and either select File > Save or exit the viewer. 

5. Give the updated video a new name and save location and it will be saved as a separate video than the original. All done!
