> Editing Your Project on the Canvas
> The canvas (Figure 21) is a real-time video preview pane—a spatial representation of the visual elements of your project—which allows you to size and position the visual elements of your project. How (and where) the elements display at any point in time is controlled by the position of the scrubber on the timeline.
> To move the Canvas, click and drag it using your mouse. When you do this, the position values change accordingly in the Video tab. If you press the Space Bar while moving the Canvas, the position value are not changed.
> If you are using atrackpad, pinch fingers closer of farther apart on the trackpad to zomm in or out. You can also scroll in any direction using two fingers on the trackpad.
> Figure 21. Using the Canvas Pane
> The center rectangle (which may be obscured by a clip, as shown above) represents the video frame of your project. Its dimension (which is set by clicking the Canvas button and using the canvas controls) determines the frame size of your video when you export or publish it.
> The gray space around the video frame rectangle is workspace; space that isn’t included in exported video. You can use this space for off- or partially off-screen visual elements for scaling or pan effects.
