Grok ImagineFree Grok Imagine AI Video Generator
Turn text or a photo into a clip with sound generated in the same pass
Grok Imagine Video is xAI's video model, and it runs here with free credits when you sign in. Describe a shot or upload a starting image, and the picture, motion and audio are generated together — sound effects, ambience and dialogue land on the action instead of being layered on afterwards.

How It Works
Create AI Videos in 4 Simple Steps
Choose Your Input
Start from a text prompt, or upload a starting image to animate. Grok Imagine handles both from the same workspace.
Describe the Shot
Write the action, the camera movement, the mood — and the sound you want. The audio is generated from the same prompt, so mention it.
Configure & Generate
Set aspect ratio, duration and resolution, pick Normal, Fun or Spicy, then generate. Credits are charged per run and refunded automatically if one fails.
Download & Share
Preview the clip for free. On a paid plan, download it at full quality and post it straight to social, an ad, or a client deck.
Grok Imagine Video Generator Features
Sound, Motion and Camera Moves in a Single Pass
Text-to-Video
Describe a shot — subject, action, camera move, mood — and Grok Imagine builds it from nothing. No starting image needed.
Image-to-Video
Upload a photo, illustration or product shot and Grok Imagine animates it with natural motion and camera movement while holding the original framing.
Native Audio, Same Pass
Sound effects, ambience and dialogue are generated with the picture, not bolted on after. A door slam lands on the frame it should, and a quiet street actually sounds like one.
Believable Motion and Physics
Movement holds together across the length of a clip — fewer warps, more convincing weight and momentum than earlier video models.
Normal, Fun and Spicy Modes
Three generation modes change how far the model leans into a style. Spicy loosens the restrictions for bolder output, and it is a dropdown here rather than a setting buried in the X app.
Clips up to 30 Seconds
Grok Imagine renders 480p and 720p clips up to 30 seconds long in 16:9, 9:16, 1:1, 3:2 and 2:3 — and when you need 1080p, Wan 2.6 and Seedance 1.5 Pro sit in the same picker.

Grok Imagine Video Generator FAQ
Everything You Need to Know About Grok Video
Grok Imagine Video is xAI's video model. Give it a prompt or a starting image and it generates the picture and the audio together in a single pass — motion, camera moves, sound effects and dialogue in one clip. It runs here in the browser with free credits to start.
From 1 to 30 seconds, depending on which model you pick: Grok Imagine Video covers 6 to 30 seconds, and Video 1.5 covers 1 to 15. Longer pieces are usually better assembled from several clips than asked for in one go.
Yes, and it is the main thing that sets it apart. Sound effects, ambience, music and dialogue are generated in the same pass as the picture, so they land on the action. There is no separate audio step and no second tool.
Grok Imagine is fast and generates audio natively, which makes it strong for social-length clips. Sora 2, Veo 3, Kling 2.1 and Seedance are in the same model picker here, so you can run one prompt through several and keep what works — including 1080p from Wan 2.6 or Seedance 1.5 Pro.
Yes. Every paid plan includes video downloads and a commercial license, so your clips can be used for social content, ads, product demos and client work. You keep the rights to what you create. On the free plan you can generate and preview videos, and downloading unlocks when you upgrade.
Spicy is one of three modes — Normal, Fun and Spicy — in the Grok Imagine video generator. It loosens style restrictions for bolder, more expressive output. Pick it from the Mode dropdown; you do not need to change any setting in the X app first.
Describe one clear action rather than stacking several — piling on camera moves muddies the motion. Name the camera move, and say what the shot should sound like, because the audio comes from the same prompt. Starting from an image gives you far more control over framing than text alone.
Text prompts and starting images, plus reference frames on the Grok Imagine video model for holding a character or a scene steady across shots. Prompts run to 4,000 characters.
You get free credits when you create an account, topped up by the daily check-in, and no credit card is needed to try it. Paid plans are there for volume. On grok.com itself, Grok Imagine now sits behind xAI’s paid SuperGrok tiers.
Grok Imagine renders at 480p or 720p. If you need 1080p, Wan 2.6 and Seedance 1.5 Pro in the same picker generate at 1080p from the same prompt and the same credit balance.
