After you add clips to your project, you can quickly and easily arrange them spatially on the canvas, and you can crop, resize, rotate, add filters, etc.To operate on a clip, click to select it. ScreenFlow highlights the clip (both on the canvas and the timeline). When you select a clip on the canvas, it also selects it on the timeline.Note: You can select a clip on the canvas or timeline when you want to view or change its properties, which is done using the properties panes to the right of the canvas.
