This locks envelope points to media events so that they move with the events, but it also locks track keyframes to the events. ✓ Click Lock Envelopes to Events in the timeline toolbar. If you swap media in the affected area, the keyframed effects will apply to the new media automatically. If you move media events away from keyframes or out of areas defined by the keyframes, the keyframed effects will no longer apply to those events. The states defined in track keyframes will apply to any media events in that track at the keyframes. If you leave the cursors synced, you may inadvertently create keyframes in places you don’t want them. ✓ Or click within the animation timeline to see the exact result of your keyframe in the main project Video Preview window. ✓ For example, if a media event in a track above the media event you’re editing overlaps your media event, click the edge of the overlapping event to set both the timeline and animation cursors to that exact point. You can use this sync to choose exact points for keyframes in relation to other media events on the main timeline. The timeline cursor jumps to that point, and the animation timeline cursor jumps to the corresponding frame within the media event. ✓ Click a point on the main timeline within the area of the video event. The animation timeline cursor jumps to that point, but the main timeline cursor jumps to the corresponding point within the media event on the main timeline. ✓ Click a point on the animation timeline. The cursors on the main timeline and the animation timeline are now synced. Experiment and see which one works best for your needs. Other keyframe interpolations produce other effects. Instead of a sharp angular zoom in/zoom out it, it’s curved and smoother, and probably more pleasing to watch. ✓ Choose the Smooth keyframe interpolation. Now the zoom slows down as it approaches the persons’ face, seems to hold briefly on the face, and then starts to zoom out slowly and gradually get faster. It zooms in, reach its closest point, then zooms right back out, which can be jarring. In our zoom in/zoom out example, a linear progression might seem harsh, because the zoom won’t hold on the person’s face. Changing the interpolation changes the steps. ![]() By default, keyframe interpolation is Linear, meaning every step between keyframes is exactly the same degree. The interpolation defines how aggressive the change between keyframes is. ✓ 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. Right-click the very first keyframe, select Copy, then right-click the last keyframe, and paste. ✓ You can also copy keyframes to do this. 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. 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.
