How it works

How to generate with Grok Imagine

Open the AI Studio
Open AI Studio from the editor and choose Grok Imagine. What it generates lands in the project you are already working in.
Attach your image and pick Grok Imagine
Upload the still you want moving. The picker switches to image-to-video models as soon as an image is attached. Set the length within what it accepts (4s to 15s) and add a prompt describing the motion.
Lay it under your recording
Grok Imagine generates picture only, which is what b-roll wants to be. Put it on the timeline over the part of your recording it illustrates and let your own audio keep running underneath.

What Grok Imagine is for

Grok Imagine is an image-to-video model from xAI, available in REQO's AI Studio. It animates a still you upload rather than inventing a shot from a prompt alone. Clips run 4s to 15s, and it sits in the fast and cheap tier at 5 credits for its shortest clip.

Against the 12 other image-to-video models in the studio it is the third-cheapest to run and comes back faster than any of them, at 5 credits and about 40 seconds a generation.

In the picker it is described as: xAI, fast and cheap.

What a Grok Imagine clip costs

A Grok Imagine clip runs from 5 credits (4s at 480p) to 22 (15s at 720p). Resolution is part of the price, so pick it with the length. These are the figures the studio charges, shown again before each generation.

When to pick Grok Imagine

You already have the frame - a product shot, a still from a shoot, an image you generated a moment ago - and want up to 15s of movement out of it, at 720p or 480p.

The clip you need fits inside 4s to 15s, and you can wait about 40s for it.

You need 16:9, 9:16 or 1:1 - no other image-to-video model here accepts as many natively.

You are iterating and want the next attempt back quickly: at about 40s, nothing here answers sooner.

Where it runs out: xAI built this endpoint to animate a still rather than to generate one, so there is no prompt-only path into it. Clips stop at 15s; Seedance 2.5 goes to 30s if you need one shot to run longer. Resolutions are limited to 720p or 480p, and the higher ones cost more credits. It produces picture only. Seedance 1.5 Pro generates a soundtrack with the clip, at 2 credits against this model's 5. At 5 credits it is not the cheap option: PixVerse V6 runs at 3.

What to weigh Grok Imagine against

These are the 5 models closest to Grok Imagine on price, render time and clip length - the ones worth weighing it against. Every model REQO offers is linked below.

They all run on the same timeline, so the choice is per clip rather than per project: generate an establishing shot with one and a quick filler with another, then cut them together in the same tab. Credit costs are each model’s cheapest clip, its shortest length at its cheapest resolution; longer clips cost more.

Generating is the easy half

Most generators hand you a clip and stop, which leaves you downloading files and re-uploading them somewhere else to make anything of them.

In REQO the Grok Imagine result lands next to your screen recordings and uploads, about 40 seconds after you attach the still. Pick the aspect ratio before you generate (16:9, 9:16, 1:1); afterwards it is a crop.

The AI Studio (talking avatars, text-to-video and AI images) and the AI clip tools (background removal, chroma key, face touch-up, noise cancellation, auto cleanup, auto b-roll, auto-zoom) are Pro features. Generation includes 100 credits a month plus top-ups.

FAQ

Grok Imagine: questions

How much does Grok Imagine cost?

From 5 credits (4s at 480p) to 22 (15s at 720p), and the studio shows the exact figure for the length and resolution you pick before it charges you. AI Studio is part of Pro.

How long can a Grok Imagine clip be?

4s to 15s. That is a hard limit of the model, not a plan limit - a longer piece is several generations laid end to end.

What aspect ratios does Grok Imagine support?

16:9, 9:16, 1:1, at 720p, 480p. Anything else is a crop afterwards, which the free crop tool handles.

Can Grok Imagine generate a video without an image?

No. This endpoint animates a still, so an image is required. Remove the image and the studio switches you to the text-to-video side of the same family automatically.

Does Grok Imagine generate audio?

No. It produces picture only, so add music, a voiceover or your own recorded audio on the timeline afterwards - which costs nothing on top of the 5 credits the clip itself uses.

How long does a generation take?

Usually about 40 seconds for the 5-credit shortest clip; longer clips and higher resolutions take proportionally longer. Generations keep running if you switch tabs.

Can I edit the generated clip?

Yes, and on the same timeline as everything else. The still you animated stays in the project, so you can re-run it with a different prompt and cut the two takes together. Captions come off the transcript, and the finished piece exports or shares as one link.
