ScreenFlow User Guide | Main Window : Preview — Crop Canvas
| Crop Canvas If you want to globally crop your presentation, you can do so with the Crop Canvas feature. You would use this feature if you didn’t want to show the whole screen recording. For example, if your screencast is going to show one area of your desktop, you could use the Crop Canvas to accomplish this task. To crop the canvas, click on the button in the main window. The preview area will then look like the following: Editing the Cropping To change the cropping, move the mouse to the edges of the preview, click down and move toward the center. When you are done, press the “Apply” button, and the canvas size will change. Options Snap to Front Window If this option is checked, then guidelines will be presented for the foreground window. This allows you to very quickly globally crop the presentation to the front-most window. Reset Reset to original canvas size, removing any cropping. Cancel Cancels the current crop editing session, restoring the previous cropping values. Apply Applies the current global crop values to the presentation and ends the crop editing session.
