For those who skipped the last movie and who have access to the project files,…we are in project AEA_Advanced Animation, and we're looking around inside comp 00-keyframes 101.…To reveal the keyframes, you can press U to reveal all animated properties.…And we were just discussing that keyframes contain a lot more than just a…particular value at a particular point in time.…For one, if you have two different keyframes at different points in time with…different values, After Effects will interpolate between those values, vary from…one value to the next over that period of time between the two keyframes.…
In other words, it just doesn't abruptly change when it hits a new keyframe.…And if I RAM-preview, you can see this.…You can see how scale doesn't jump.…It gradually scales the object up and down. And you'll also see that…position doesn't jump from keyframe to keyframe; the object actually moves…along its motion path.…But keyframes can do a lot more than just hold a value and interpolate;…they also define how fast those values change from keyframe to keyframe and…
