Resize a clip, move it within the frame, or rotate it in a few quick steps. To resize or rotate, simply highlight the clip on the timeline you want to edit, hover your cursor over the outline of the video in the playback window, and then click and drag.
You can make additional adjustments like cropping your video, applying an edge feather to soften the edges, or auto reframing to automatically track the subject of your video after you change the video’s shape (or aspect ratio). Find these effects under Effects › Video Effects › Transform.
If you’re working with a shaky video that makes cropping tricky, video stabilization might be necessary to focus on your subject.
