An apparatus and method for creating and storing an animation and for linking the animation with a video. A sequence of video images is inspected to identify a first transformation of a scene depicted in the sequence of video images. A first image and a second image are obtained from the sequence of video images, the first image representing the scene before the first transformation and the second image representing the scene after the first transformation. Information is generated that indicates the first transformation and that can be used to interpolate between the first image and the second image to produce a video effect that approximates display of the sequence of video images. Regarding the storing of an animation, a set of keyframes created from a video is stored in an animation object. One or more values that indicate a first sequence of selected keyframes from the set of keyframes is stored in the animation object along with information for interpolating between the keyframes of the first sequence. One or more values that indicate a second sequence of selected keyframes from the set of keyframes is also stored in the animation object along with information for interpolating between the keyframes of the second sequence. The number of keyframes in the second sequence is fewer than the number of keyframes in the first sequence. Regarding the linking of a video and an animation, a data structure containing elements that correspond to respective frames of a first video is generated. Information that indicates an image in an animation that has been created from a second video is stored in one or more of the elements of the data structure. |
