Creating realistic videos from scratch (i.e., unconditional video generation (UVG)) requires the model to learn the distribution of the video data. In other words, we are essentially learning a density function from which we can sample unseen videos. Video generation, however, differs from image generation since we must consider the temporal aspect in addition to the spatial aspect. Such approaches, however, were limited to generating short videos with simple dynamics (e.g., linear motions such as moving trains). This limitation stems most likely from failing to treat the two aspects effectively. Specifically, a video can be decomposed into two orthogonal elements: the motion (i.e., movement of an object(s)) and the appearance (i.e., background, style of the object(s), etc.), where the former is concerned with the temporal aspect, and the latter the spatial aspect. However, existing approaches, while separately learning motion and appearance to some extent, fail to learn the true dynamics of motion as they all treat videos as a sequence of frames bound by discretized, fixed-interval timesteps.
