Hello @williamc46066. QUik for desktop will allow you to trim video clips, but it does not have the slow motion feature. If you are intent on using desktop, there are other programs here that you can explore. The editors can be used to view and edit your GoPro footage.
Alternatively, you may use the GoPro App and Quik for mobile applications. The instructions on how to create a movie using Quik for mobile are detailed in this article How To Create A Video Using Quik for mobile . Trim features, slow motion effects and different themes are available. Hope this helps.
