You can also add and adjust keyframes in the Motion and Filters tabs of the Viewer window. You'll find the keyframe button next next to each control. You can add keyframes by pressing this button, and they'll appear to the right in the mini timeline of the Viewer window. In the image above, I added a keyframe where I want to begin the change in scale of my video clip. The keyframe shows up in green next to the Scale control.
