that’s what I was talking about when I said sliding the white bar to the left. Slide the video until you get to the beginning of the clip you want. Then shorten it to the exact length you need by sliding that bar back and forth until you have the exact clip you want. It’s kinda trial and error and takes a bit of fineness, but you’ll get it. Click add and you will have a short little green bar at the top, kinda like in my first picture. You then can click the arrow to choose a video again to add more clips, they can be from the same or a different video. You can keep repeating this until you have filled the green bar at the top (all six seconds) or have exactly the clips you want, then click finish to complete rendering all your clips together. And even after you have rendered your video, you can still clip the edit in the lower right.. That will allow you to edit or even delete individual clips.
