Are you familiar with audio keyframing? So, what is this audio keyframing? Does this term appear new for you? It won't anymore as we are here to explain. In the world of animation, knowing about keyframes is more critical. Have you ever noticed certain scenes while watching a movie that would reflect different audio volume in other video clips? It is all because of this process of keyframing that allows you to change the parameter values in a video clip. A keyframe on the clip specifies the start and end of the changes that occur in the frames, images, or drawings.

Filmmaking, hand-drawn animation, and short movies are critical applications where keyframing finds the place, especially in changing positions, scaling subjects, and customizing opacity. Although the concept might seem in-depth and confusing, implementing such keyframes isn't a hassle as you think if you have a handy video editor. Today, let's look at one such software, Final Cut Pro X, which is the popular tool for Mac at present in keyframing. With no delay, scroll down to add and edit audio keyframes in FCPX at ease.
