Increasing the life span of a new object does not animate the object. It only produces a static object that exists in a number of successive frames. To animate a static object, you must tween it or animate it frame-by-frame. For more information about animating frame-by-frame, see “Animating objects frame-by-frame” in the Help.

To increase the life span of a new object

1Select a new object.

2In the Timeline docker, drag the black dot associated with the object to the frame you want.

Tweening objects

Tweening lets you animate objects in a movie. You change their position and appearance at specific frames in their life spans, and Corel R.A.V.E. creates the frames in between.

Before you can tween an object, you must increase its life span so that it exists for more than one frame. For more information, see “Increasing the life span of objects” on page 330.

How tweening works

To tween a static object, you can turn the end frame of the object’s timeline into a keyframe. The start frame of the object’s timeline automatically becomes another keyframe that stores information about the object’s original state. Modifying the object at the end keyframe produces an animated object that changes gradually from its original state to its modified state. The rate of change is determined by the number of intermediate frames, and by the frame rate of the movie. For more information about frame rate, see “Setting the properties of movies” on page 326.

You can also tween a static object by turning any intermediate frame in its timeline into a keyframe, and then modifying the object at that keyframe. The start and end frames automatically become keyframes with the object in its original state. This produces an animated object that changes from its original state to its modified state and then back to its original state.

Frames with an interior border indicate keyframes. Turning the end frame in an object’s timeline into a keyframe and modifying the object at that keyframe produces an animated object that changes over time (top). Turning an intermediate frame in an object’s timeline into a keyframe and modifying the object at that keyframe produces an animated object that changes over time and returns to its original state (bottom).

What can be tweened

Corel R.A.V.E. lets you tween object properties such as size, position, rotation angle, and outline, as well as interactive effects you’ve applied, such as contour, transparency, fill, envelope, distortion, and drop shadow. You can tween several object properties and effects at the same time.

You can tween the size, position, and rotation angle of an object simultaneously to make it roll across the stage as it recedes. Frames with an interior border indicate keyframes.

Changing the fill of a silhouette and its background at an end keyframe produces an image that gradually changes color. In this movie, the sun is also tweened to move along a path.

Tweening a distortion effect applied to an object produces an animated object that changes its shape. Frames with an interior border indicate keyframes.

Tweening the drop shadow of this object produces the effect of a light moving over it. Frames with an interior border indicate keyframes.

Not all attributes of object properties and interactive effects can be tweened. For more information, see, “Tweening limitations” in the Help.

Creating motion

Corel R.A.V.E. lets you create interesting motion effects by tweening the position, size, skew, and rotation angle of an object.

Tweening the position of an object makes an object move across the stage. You can make an object move in a straight line or make it follow a path. For information about creating paths, see “Drawing lines” in the Help.

When you tween the size, or scale, of an object, the object appears to be moving closer or receding. When you tween the skew of an object, you add depth to the object over time, and the object appears to rotate. You can rotate an object or an extruded object over time by tweening the rotation angle. Tweening the rotation angle of an object makes the object move around its center of rotation. When you tween the rotation angle of an extruded object, you can rotate the object around its x, y, or z axis. For both objects and extruded objects, you can set the rotation direction and number of rotations.

For information about changing these object properties, see “Working with objects” in the Help.
