Keyframe audio and speed changes

MacWorld UK has 26 iMovie tips that range from beginner to “advanced.” For instance, all this time I thought you had to laboriously option-click to set keyframe points to adjust volume in small sections of a clip. Nope.


And I thought you had to split clips to apply speed changes. Nope. Set some keyframes and adjust speed – iMovie will “smooth” the speed transition from both sides of the edit.
