The interpolation defines how aggressive the change between keyframes is. By default, keyframe interpolation is Linear, meaning every step between keyframes is exactly the same degree. ✓ Right-click a keyframe to choose an interpolation from the context menu. Now let’s refine the animation a little and change how VEGAS interpolates keyframes. ✓ Click, hold, and slide the center keyframe left or right to adjust the exact timing of the zoom. You’ve created a complete animation with keyframes!

The video zooms into the person’s face and then immediately zooms back out again. ✓ Click the left edge of the media event and play the project. The new keyframe takes on the properties of the first keyframe. ✓ You can also copy keyframes to do this. Right-click the very first keyframe, select Copy, then right-click the last keyframe, and paste. The Frame box now goes back to its original position and the full zoomed-out image is restored. A new keyframe appears on the last frame. We placed the cursor on that keyframe, so the cursor jumped to the last frame. If the cursor had been in a position before the keyframe you set, the cursor would have jumped to that keyframe. The animation timeline cursor moves to the last frame on the timeline, even though is there is no keyframe. ✓ Click the keyframe you created. Click Last Keyframe. With so many independent parameters under your control, you can create amazingly sophisticated animations and effects with keyframing. States can be very complex and involve many parameters, like size, shape, color, rotation, brightness, and many more, any of which can change between keyframes.

As the timeline progresses from one keyframe to the next, VEGAS interpolates the positions between the keyframes, and the image moves between the first position and the second position.

The next state may only be a different position, but the same size. In a simple example, a state may be simply the size and position of an image. It then interpolates intermediate frames between the keyframes and creates a natural flow between one state to the next.Ī state is a combination of parameters. As the project plays in between the keyframes, VEGAS calculates steps in between the two states. Then, some point later in the timeline, you define another state and set a keyframe for that. At its most basic, the first keyframe defines your initial state. Keyframes contain states of how you want things to be, whether it’s a zoom amount, a specific color, or any of hundreds of possible parameters and thousands of possible combinations of parameters.
