Grok Imagine: Image to Video with Audio

HOW IT WORKS

Step 1. Upload your image The still you want to animate. A clear subject with room to move gives the cleanest motion. Works great with: photos · portraits · product shots · character art

Step 2. Describe the motion Write a short prompt for what should move and how. You can describe the sound and mood too, like "the raccoon steps forward and waves as the camera zooms out."

Step 3. Hit run and download You get back a 720P clip with synced audio generated in the same pass. Preview it in the workflow, then download. Ready for: Premiere · CapCut · DaVinci Resolve · any editor

First time? Leave every setting as-is. The defaults (720p · 6 seconds · auto aspect ratio) are the right starting point for almost everyone.

RECOMMENDED SETTINGS

Quick-start guide. Find the goal that matches yours and copy the settings.

• Standard clip (most people) Start here — 720p · 6 seconds · auto aspect ratio. The right starting point for almost everyone.

• Want a faster render — Drop to 480p. The clip generates quicker, with a small trade in sharpness.

• Want a longer clip — Raise the duration. More seconds give the motion more room to play out and take a little longer to generate.

• Want sound or a voice — Describe the audio in your prompt. Grok Imagine generates synced sound effects and ambience in the same pass as the video.

• Set the shape — Switch the aspect ratio from auto to 16:9 or 9:16 to match where the clip will post.

• Motion is too wild or too still — Name the action and its pace plainly. "A slow zoom out as she turns to camera" steers better than "make it move."

Prompt: Describe what moves, how it moves, the camera, and the mood. Keep it concrete. Adding a sound cue in the same prompt tells the model what to score the clip with.

USE CASES

🎬 Social & Short-form Animate a single image into a clip for Reels, Shorts, or TikTok, with sound included from the start.

🎨 Artists & Illustrators Bring character art or a portrait to life with motion and a matching soundtrack while the style holds.

🎭 Creators & Meme-makers Make a quick, shareable animated clip from any image. Upload, run, and post.

WHAT WORKS BEST / WHAT TO AVOID

FAQ

What is Grok Imagine? Grok Imagine is xAI's image and video generation system, built on its Aurora architecture. This workflow runs the image-to-video model: you give it a still and a motion prompt, and it animates the image into a short clip with sound. The autoregressive design helps it hold the subject and framing steady across the clip.

Does Grok Imagine generate audio along with the video? Yes, and it is a defining feature. Grok Imagine produces synchronized audio in the same pass as the video, covering sound effects, ambience, and lip-sync, all driven by your prompt. There is no separate recording or dubbing step, so the clip comes out with sound built in.

What resolution and length does this workflow produce? It defaults to 720P at 6 seconds. You can drop to 480p for a faster render or raise the duration for a longer clip. Grok Imagine generates at 24fps, which gives the motion a smooth, cinematic feel.

How is Grok Imagine different from other image-to-video models? Two things set it apart: built-in audio and its Aurora architecture. Many image-to-video models output silent clips you have to score yourself, while Grok Imagine generates picture and sound together. The autoregressive approach also helps reduce subject warping, so faces and objects stay consistent across the clip.

Can I use a vertical or square image? Yes. Grok Imagine supports several aspect ratios, so a vertical or square source works as well as a widescreen one. Set the aspect ratio to match your image, which is worth doing for vertical social formats.

Can I use the results commercially? Yes. Videos you generate on Floyo carry full commercial rights, so you can use them in social posts, ads, client work, and shipped projects. You are responsible for having the right to use the source image you upload.

How to run Grok Imagine online? You can run Grok Imagine online through Floyo. No installation, no setup, no API keys to wire up. Open the workflow in your browser, upload an image, write a prompt, and hit run. Free to try.
