Why creators choose Grok Imagine

Grok Imagine is xAI's specialized video extension model, built for one thing and does it well: extending video while keeping the camera locked. When your source footage has strong framing and motion, Grok Imagine continues it without a jarring cut. It's focused and efficient, generating 2 to 10-second continuations that preserve the exact camera dynamics of your source clip.

Camera continuity without the seam

The hardest part of video extension is keeping the camera angle and motion identical across the cut. Grok Imagine preserves both. Pan the same direction, zoom at the same rate, follow the same subject. The seam disappears because the camera never breaks character. This is critical for professional edits where any camera jitter or inconsistency reads as obvious.

Physics that makes sense

When you extend a shot of motion, the physics have to track. A falling object accelerates the same way, water flows in the same direction, and a moving person's gait stays consistent. Grok Imagine writes to real-world physics, so your extension feels like it's part of the same take. This is especially important for product demonstrations and mechanical motion.

Two-to-ten-second continuations

That's enough to extend a reveal, finish a move, or land a beat without feeling incomplete. You don't need long continuations; you need accurate ones. Grok Imagine's narrow focus on extension means it excels at this specific task, generating smooth continuations that lock to your source.

Sound builds on your source

Grok Imagine takes the audio tone and style from your source and carries it into the extension. No jarring silence, no sound that doesn't belong. If your source has dialogue, ambient sound, or music, the extension maintains that sonic continuity. This keeps your audience immersed across the cut.

How to use Grok Imagine in Craze

1. Upload the video clip you want to extend.
2. Describe what happens next. "Keep the pan going and reveal the product on the table" or "Maintain the zoom and cut to the person's reaction."
3. Say you want Grok Imagine for video extension. Craze runs the model when you ask for it by name.
4. Craze generates the continuation and cuts it onto your timeline after the source clip.
5. Review the join in the editor. If the seam is tight, move on. If you want to adjust the transition, regenerate.

Grok Imagine capabilities

Grok Imagine specializes in video extension. It takes your source clip and generates a 2 to 10-second continuation that locks to the same camera framing and motion. The model preserves the physics of your scene, so if an object is falling or moving in a specific direction, the extension continues that motion naturally.

Sound is included in every extension, carried forward from your source clip's audio tone and style. Grok Imagine is available on Craze when you ask for it by name. Craze may recommend it for video extension, so you have control over when to use its specialized extension capabilities.

Grok Imagine does not do text-to-video or image-to-video generation. For full generation from scratch, use Grok Imagine 1.5 instead. For extension with other models, Veo 3.1 also supports video extension alongside text and image input.

Grok Imagine pricing

You pay per second of generated video. $0.079 per second of added video. This page covers extension only; use Grok Imagine 1.5 for new clips. Use the cost calculator on this page for your extension length.

Sound generation is included in the per-second rate. Longer extensions cost more, but Grok Imagine's focus on camera consistency means you typically get a good result in a single generation without many retries.

Who Grok Imagine is for

Product demonstrations and reveals

Extend a clean product shot to show more angles or details. Grok Imagine holds the camera steady while the product moves through the frame.

Music videos and choreography

Extend a dancer's movement in the same camera framing. Keep the angle and let the motion continue naturally into the extended section.

Dialogue-heavy cuts

A reaction shot or a close-up of a speaker can be extended to emphasize a beat or buy time. Grok Imagine keeps the camera locked on the subject.

Grok Imagine vs Grok Imagine 1.5

Grok Imagine does video extension only, at 720p or below, with strong framing continuity. Grok Imagine 1.5 adds text-to-video, image-to-video, and reference modes, and goes up to 1080p. Use Grok Imagine when you're extending existing footage; use Grok Imagine 1.5 when you need full generation from scratch.
