Grok Imagine Video 1.5
Grok Imagine Video 1.5 is xAI’s improved image-to-video model, built for better quality at faster speeds. Now generally available on the Imagine API as grok-imagine-video-1.5, it gives creators and developers a way to start from an image, describe the motion, and choose the resolution and duration for the generated video. Grok Imagine Video 1.5 and Video 1.5 Fast are described as xAI’s best image-to-video models yet, with better motion, better physics, better audio, and faster generation for real creative work. Audio and speech are generated in the same pass as the visuals, so sound effects, ambience, and dialogue land on the action, while speech is clearer and better synchronized. Motion and physics are also improved, helping movement hold together across the length of a clip with fewer warps and more believable weight and momentum. Grok Imagine Video 1.5 Fast almost doubles generation speed, producing 6-second, 720p videos in about 25 seconds.
