17. Keyframing

What is Keyframing?

Keyframing in Producer is all about creating motion and effects for your
layers and captions. Keyframing is what all of the effects in Producer are
built on. A keyframe is used to control what will happen to your layer or
caption, and when that will happen in time. In short, a keyframe is a point
in time where something will happen. That “something” is where you come
in.

The History of Keyframing

The term “keyframing” comes from traditional forms of hand animation,
dating back to the early days of companies like Warner Brothers and Disney.
Creating all of the individual pictures that would be rapidly combined
together to give the illusion of motion was a big job. To make this process
easier, animators were broken into two groups. There were the lead
animators and the junior animators. The lead animators created critical
pieces of the animation sequence, which were called keyframes. Each one
of these would be created for a major change in the animation, such as the
start and end of an action.

The junior animators would take these major pieces, or keyframes, and
create all of the pictures that would have to appear in order between those
two keyframes. This process was called “tweening”. In short, the lead
animator would draw how he wanted something to appear at the start and
end. Then he would pass it to the junior animators who would fill in the
gaps between the two, making the motion complete.
