Keyframe

video

A frame that defines a key moment in an animation — traditionally, lead animators drew keyframes and assistants filled the in-between frames. AI video borrows the concept: you supply start (and sometimes end) frames as images, and the model generates the motion connecting them. This gives precise control over where a shot begins and ends — great for seamless transitions between scenes. Example: generate two stills of your character, seated at a table and then standing by a window; feed both as keyframes and the model animates the movement between them.
