How many credits per second does Grok Imagine Video cost?

Per second of video, Grok Imagine Video costs 13 credits at 480p and 18 credits at 720p. A clip is charged by its length, so a clip twice as long costs twice as much; the table on this page lists the live rate for each resolution.

How long can a Grok Imagine video be?

Each clip can run from 1 to 15 seconds on Zero Kit. Most social clips work at the short end, which also keeps the cost down.

Does Grok Imagine Video make videos with sound?

xAI built Grok Imagine Video as a video-and-audio model that can generate sound and dialogue with the picture. The samples on this page are still images, so listen to your own clip to confirm the sound track on Zero Kit before you post it.

What aspect ratios does Grok Imagine Video support?

It offers 7 aspect ratios on Zero Kit, covering portrait, landscape and square frames. Choose one in the editor before you generate; if you start from a photo, match the ratio to the photo so it is not stretched.

Can I turn a photo into a video with Grok Imagine Video?

Yes. Add the photo in the editor and it becomes the first frame, then describe the motion and the camera move in one or two sentences.

Can I use the results commercially?

Yes, on a paid plan. Images and videos made on a paid plan can be used commercially, including product pages, ads and social posts, subject to our Terms. Output from the free plan is for personal, non-commercial use only.

Are my prompts and uploads used for training?

No. We do not use your prompts, uploads or results to train AI models. To run a generation, the prompt and any reference files are sent to the provider of the model you picked, which processes that request under its own terms.

About Grok Imagine Video

Grok Imagine Video is the original video model in xAI's Grok Imagine line. It turns a text prompt or a still image into a short clip with realistic motion and object interactions, and it follows camera directions such as zoom in, dolly out, tilt up and pan. xAI built it as a video-and-audio model and designed it around speed and cost, so running an idea a second or third time stays cheap.

Its natural home is the single shot: one subject, one action, one camera move. Milk poured into espresso, noodles lifted from a bowl, a puppy chasing bubbles, a hand riding the wind outside a car window, the kind of moment that works as a post on its own. xAI lists portrait, landscape and platform-ready aspect ratios, so you can make a vertical clip for a story or a wide one for a feed without cropping afterwards. When a piece needs several connected shots or cleaner speech, Grok Imagine Video 1.5 in the same family is the newer option.

On Zero Kit it runs from the editor at the top of this page. Write the moment or add a photo, set the length between 1 and 15 seconds and generate. Each second is charged at the resolution you choose, and short clips keep the cost of a test low, which suits the try-again rhythm of social content.

What Grok Imagine Video does well

One shot, one moment

Grok Imagine Video is most dependable when a clip holds one moment from start to finish. The birthday sample is a good pattern: a slow dolly-in on a pastel pink cake, the candles going out on a single breath, thin smoke curling up while friends clap in the blur behind. There is one action, one camera move and one warm light source, so nothing competes for attention. Describe the moment and the camera move in a sentence each, and let the clip end on the result of the action, which here is the smoke rising.

First-person vlog

First-person, handheld shots suit Grok Imagine Video because they need only one continuous movement. xAI says the model understands realistic motion and object interactions, and that is what makes a POV walk read as real: a hand holding a paper-wrapped bouquet of ranunculus in the foreground, buckets of tulips and peonies passing on both sides, soft morning light. Write "first-person view" or "handheld from the passenger seat" at the start of the prompt, say what the hand is holding, and keep the walking pace gentle so the frame does not shake too much.

Satisfying loop

Short, tactile clips such as slicing, pouring and squishing are a good match for Grok Imagine Video. The sample shows a thin knife cutting through a block of layered pastel kinetic sand, the slice crumbling away onto a clean white table. Keep the camera still and the background plain, and describe the texture in detail, such as "layered lilac, mint and peach, crumbling in a soft cascade". The model does not promise a seamless loop, so to make one, keep the scene the same at the start and the end, then trim the clip in an editor where the motion repeats.

Resolution	Plan	Credits

720p	Plus	18

Limitations to know

It is built for single shots. Asking for several scenes, or a story with cuts, in one clip tends to give a muddled result, so generate each shot separately and join them in an editor.
Resolution tops out at 720p, which looks right on a phone but can look soft on a large screen or in a wide edit.
Fast, complex motion can warp, with limbs bending or objects changing shape mid-action, and close contact between people is harder still. Lettering in the frame is not reliable either, so add captions in an editor.

How to write prompts for Grok Imagine Video

Describe one moment: the subject, the action and how it ends. "Milk poured into espresso until a tulip forms" works better than a list of events.
Name one camera move, such as zoom in, dolly out, pan or tilt up, or write "handheld" for a vlog feel.
Pick the aspect ratio before you write, vertical for stories and reels, wide for feeds, and compose the prompt for that frame.
Start from a photo when the look has to match an existing image; the photo becomes the first frame and the prompt only needs to describe the motion.
Add texture and light words, such as "glossy noodles in warm steam" or "pastel morning light", since a social clip is judged on its first second.
