Animating a video effect

If you want to create an animated effect, use the keyframe controller at the bottom of the Video Event FX dialog to establish distinct settings throughout the duration of the effect.

During playback, intermediate frames are interpolated to create smooth motion.

Automating video output effect parameters with the bus track

You can think of VEGAS Pro as having a single video bus: when you have multiple tracks, they are all composited to a single video output.

When you choose Video Bus Track from the View menu, a bus track is displayed for the video output. You can add keyframes to adjust effect parameters over time.
