Definition
A keyframe defines what a property equals and when. Animation needs at least two: one keyframe alone is a static value, but two keyframes with different values produce motion as the software interpolates ('tweens') the frames in between. The term comes from hand-drawn animation, where a senior key animator drew the important 'key' poses and junior inbetweeners drew the frames between them. Almost any property can be keyframed — position, scale, rotation, opacity, volume, crop/mask, and effect parameters like blur or color — which is why keyframes underlie everything from a lower third sliding in to a Ken Burns photo zoom to an audio fade. How the motion accelerates between keyframes is controlled separately by easing.
How Loopdesk Uses This
Loopdesk applies professionally-eased keyframe animation automatically — captions that pop in, lower thirds that slide, photo pushes with built-in movement — so creators get polished motion without hand-setting keyframes. Understanding keyframes helps you direct the motion you want in plain English and fine-tune it on the timeline.
Frequently Asked Questions
How many keyframes do I need to animate something?
At least two — one for the starting value and one for the ending value. The software interpolates every frame between them. A single keyframe is just a static value.
