Using Select Crop
To apply crop settings to your clip using the Select Crop dialog box, click the
triangle next to the Select property to expand it, then click the Select Crop
button:
¦ Note When working with the Matrox cube effect, Select Crop is available
only for the primary source.
The Select Crop dialog box allows you to crop your clip in two ways:
• Click and drag directly in the Select Crop window to create the rectangular
cropping area.
To resize your cropping area, drag any side of the rectangle. For example,
drag the right side of the rectangle to crop the right edge of your clip. To
resize the entire cropping area at once, drag one of the corners (the corner
that’s diagonally opposite the corner you are moving will remain stationary).
• Use the Left , Right , Top , and Bottom controls to crop any edge by a given
number of pixels. You can enter values in the text boxes or drag the sliders to
resize your crop area. For example, drag the
Left slider to crop the left edge
of your clip.
