First I guess I need to define the term crop with regard to video. I take a video of my pet bird on my shoulder. I want to crop the video so that only the area where the bird is, remains in the video. I searched Google for programs that would do this, and found a thread saying that Windows Movie Maker would.I'm all for freeware, so I downloaded it and now find that it will not. take a video of my pet bird on my shoulder.

How to Rotate an Object. This topic describes how to rotate an object about a specified point. To rotate an object, call Matrix3x2F::Rotation method. This method takes two parameters, the specified angle and the center point. The angle is a clockwise rotation angle in degrees, and the center point is the point about which the object rotates. The center point is expressed in the coordinate system of the object that is transformed. For example, the following code rotates a square clockwise 45 degrees about the center of the square.
The angle of rotation of a symmetric figure is the smallest angle of rotation that preserves the figure. For example, the figure on the left can be turned by 180Â° (the same way you would turn an hourglass) and will look the same. The center (recycle) figure can be turned by 120Â°, and the star can be turned by 72Â°.
