the default crop settings that you specify in the matrox advanced settings dialog box (see page 46) are applied to all your matrox effects. you can customize the crop settings for individual effects by defining keyframes at any point on the crop track. for details on how to change an effect's crop settings over time by creating and editing keyframes, see "working with keyframes" on page 88.
you can adjust the crop settings in the following ways:
· use the crop controls to crop any edge by a given number of pixels.
· choose a command from the crop menu to crop your effect by a preset amount.
· crop directly in the preview window using your mouse.
