Trim and Save video

[rooster24]

I took video with my Surface 2 Pro and while watching it, I came across the "Trim" button. I can move the Trim slider, but I don't know now to make it "Mark" a start and end point. There's nothing that says "Set Start Point" or "End Point". And if I figure that out, how do I tell it to "Save" the edited video? Any tips?

I figured it out. I went into the "Photos" app instead of the "camera icon" app. Once in the Photos app, it gave me options for trimming, saving, and others.
