The Rotate effect lets rotate, move, and zoom the video. It is especially useful to correct video which was filmed at an angle. The move and zoom effects can be used to crop video (remove unwanted portions at the edges).
Rotate works great for photographs. If you hold your camera sideways (to get full-body pictures), you can rotate your pictures 90 degrees, then create “video slideshows” from your photos (with everyone standing up, not sideways).
When you add a Rotate effect to a clip, you can adjust any or all of these settings:
Zoom either magnifies or reduces the size of the video image. Zooming in enlarges the image, giving the impression that you are moving closer to it. Zooming out decreases the scale of the image, giving the impression that you are moving away.
You can zoom-in and zoom-out of the image by using the 4 arrow controls. The - and + keys to the sides of the Zoom by 10 px button (left and right, respectively) reduce and increase the size side-to-side. The - and + keys above and below the button reduce and increase the size, top-to-bottom. You can use these keys to stretch or squeeze the image, by adjusting the height and width independently.
The Zoom by button lets you decide how big a step each click on a - or + button causes. Possible values are 1, 5, 10, and 20 pixels per click.
The Position setting lets you adjust the position of the image in the video frame. When an image is zoomed out or rotated, there will be "blank" space in the frame. By using the arrow keys under Position, you can adjust where in the frame the actual video image is placed.
The Move by button controls how far each click on an arrow moves the image. The possible values are 1, 5, and 10 pixels per click.
The rotation setting controls how far to rotate the image. You can select any number from 0 to 359. Rotation is clockwise.
When an image is zoomed out on or rotated, it no longer completely fills the video frame. The Background Color setting controls what color is used to fill in the empty parts of the frame. Click on the colored square to pick a color, or drag the eyedropper to anywhere on the screen and release it to select the color that is under it.
The Reset button restores all the settings to the default values.
