What is Grok Imagine Video 1.5?

    Grok Imagine Video 1.5 is a video model from xAI. Cinemagiq runs two versions: Grok Imagine Video 1.5, driven by a prompt or a first frame, and Grok Imagine Video 1.5 References, which builds the shot from up to 7 reference images. Native audio is always on, so every clip comes back with sound, and the length can be anything from a one-second insert to a full 15-second shot.

    Write a prompt for text-to-video, or add a first frame to set the opening picture. With a first frame, the output follows the frame and the ratio setting is ignored. There is no last frame. Clips run 1 to 15 seconds at 480p, 720p or 1080p, in seven ratios from 16:9 to 9:16. Grok Imagine Video 1.5 References renders at 480p or 720p.

    Grok Imagine Video 1.5 suits quick, punchy moments: a one-second insert, a stylized action beat, a gag that lands on a sound. The flexible length helps when a shot has to hit an exact beat in the edit. For a shot that must end on a set frame, use Kling O3 or Seedance 2.0. For long takes, use Seedance 2.5.

    • Name the style first when you want a specific look, like the duel example on this page, which opens with Anime style before the action.
    • Put the key sound in the prompt, such as steel and wind or a mug shattering, since audio is always generated.
    • Set the exact length you need. Any value from 1 to 15 seconds works, so match the beat in your edit.
