xAI: Grok Imagine Video Extensions API
Grok-Imagine-Video/Extensions continues a video from its final frame and merges the new segment with the original. It carries over the source clip's lighting, character appearance and motion inertia while accepting a prompt that introduces new narrative direction (e.g. "the car turns a corner and enters a neon tunnel"). Chain it repeatedly to build long takes and loops beyond the 15-second single-generation cap.
