> Adjusting Video to Accommodate Caption Text
> To provide a suitable background on which to display caption text clearly, use black or another dark background color, and consider using one of these techniques:

> • | Shorten the computer video frame upward (Figure 40) to create an empty rectangle at the bottom. (This creates a minor distortion in the image.)

> Figure 40. Shortening Video Frame Up for Captions

> • | Crop the computer video frame upward (Figure 41)—preserving the application window, but hiding the dock bar at the bottom. (This doesn’t distort the image.)

> Figure 41. Cropping Video Frame for Captions

> • | Reduce the frame proportionally (Figure 42), positioning it at the top center of the canvas to achieve the same goal. Leave the canvas as-is—with pillars on each side of the frame—or shorten the canvas horizontally to eliminate the pillars (remembering that this adjusts the frame size of your video).
