You can also change the horizontal and vertical scaling of a movie clip. This means that you can stretch it and shrink it, changing its width, height, or both.
Scale Properties
The properties for doing this are _xscale for the horizontal scale of the movie clip and _yscale for the vertical scale of the movie clip.
The values you need to set these two properties to is a percentage. That means that 100.0 is 100 percent of the original scale of the movie clip. You can use smaller values, such as 50, to shrink the movie clip. Or, you can use larger values, such as 200 to stretch the movie clip. You can even use negative values to flip the movie clip.
