The canvas (Figure 22) 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.
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.
