2In the Timeline docker, drag from the start frame in the object’s timeline to the frame you want.

3Drag from the end frame in the object’s timeline to the frame you want.

For a compound tween, changing the life span affects only the first or last timeline section.

You can change the life span of a group of objects by holding down Ctrl and dragging the start and end frames.

Working with tweens

A tween is the animation created by tweening. For more information about tweening, see “Tweening objects” on page 331.

You can modify how quickly or slowly a tweened object changes by adjusting object and color acceleration. For example, you can make a ball rolling down a hill speed up as it approaches the bottom of the hill.

Corel R.A.V.E. lets you copy tween properties from one tween to another. Tween properties include object and color acceleration, rotation controls, color controls, and if applicable, path properties. You can also reverse a tween. For example, a tweened object that moves from left to right while changing from red to blue can be reversed so that it moves from right to left while changing from blue to red. When you reverse a tween, you reverse the entire timeline.

You can also remove a tween. When you do, Corel R.A.V.E. deletes all keyframes, and the object maintains the properties it had at the first keyframe.

To adjust object and color acceleration

1In the Timeline docker, click an intermediate frame in the timeline of a tween.

2On the property bar, click the Object and color acceleration button .

If you want to set different acceleration rates for color and object properties, click the Lock button.

3Move the Object and Color sliders.

Moving the Object slider to the left accelerates object changes at the end of the tween, while moving the Object slider to the right accelerates object changes at the beginning of the tween. Moving the Color slider to the left accelerates color change at the beginning of the tween, while moving the Color slider to the right accelerates color change at the end of the tween.

You can adjust a section of a compound tween by holding down Ctrl, and clicking an intermediate frame in the timeline section.

To copy tween properties

1In the Timeline docker, click an intermediate frame in the timeline of the tween to which you want to copy properties.

2Click Effects ` Copy effect ` Tween from. The pointer changes to a thick, black arrow.

3Click an intermediate frame in the timeline of the tween whose properties you want to copy.

Copying tween properties does not attach a tween to a path; however, if both tweens are attached to a path, the path properties are copied.

To reverse a tween

1In the Timeline docker, click an intermediate frame in the timeline of a tween.

2Click Movie ` Tween ` Reverse tween.

You can also reverse a tween by right-clicking a frame, and clicking Reverse tween.

To remove a tween

1In the Timeline docker, click an intermediate frame in the timeline of a tween.

2Click Movie ` Tween ` Remove tween.
