Ripple Effects

The following XML defines the "ripple" category of effects in Windows Movie Maker. These effects make the video image appear as if there were ripples of water on top of it.

Following the XML are tables that specify which parameters in this XML can be changed, and which cannot.

Customizable Parameters

Parameter or
element
Type Range/options Description
WaveControls float2 0.0 – 1.0 Defines the oscillation of the wave.
WaveCenter float2 0.0 – 1.0 The image coordinates of the origin of the ripple waves.
Frequency float 1.0 – 10.0 The frequency of the ripple waves.
Speed float 1.0 – 50.0 The speed of the ripple waves.
Height float 0.0 – 1.0 The height of each ripple wave.
Point float 0.0 – 1.0 The point within the duration of the effect at which the enclosing element will have the specified value. When the time attribute is equal to 0.0, it indicates the starting point of the clip; when the time attribute is equal to 1.0, it indicates the end point of the clip.

For more information on the Point element, see Changes to the XML Schema.


Note   The "float2" type refers to a comma-delimited array of two floating point numbers. For instance, "(0.0,1.0)".
