Can Sora turn a still image into motion?

Sora — OpenAI’s video-generation family of models and companion creative app — has rapidly shifted expectations for what a single still image can become. Over the past year Sora’s models (notably sora-2 and sora-2-pro) and the consumer Sora app have added features that explicitly support starting a render from an uploaded image and producing short, coherent video clips that show believable motion, camera behavior, and audio. The system can accept image references and produce a short video that either animates elements from the image or uses the image as a visual cue in a newly generated scene. These are not simple “frame-to-frame” animations in the traditional sense; they are generative renderings that aim for continuity and physical plausibility rather than hand-animated keyframes.
