Grok Video Generator: Grok Imagine Online

Grok Imagine is xAI’s video model: the Grok video generator turns a text prompt or a photo into a short clip with sound generated alongside the picture. It runs here today through the API as our Quick tier — 5, 8, 10 or 15-second clips at 480p or 720p, sound on every clip, from 2 credits per second. That makes it the cheapest way to get a clip with audio on PictureToVideo. We are independent and not affiliated with xAI.

02Image to video

Grok image to video, step by step

Switch the generator to Image and the Grok video generator animates your photo, with sound — same lengths and same credits as text to video.

How Grok Imagine image to video works

Upload a photo you have the rights to and write a short prompt; the Grok video generator animates the scene and generates sound to match. The photo already sets the subject, place and framing, so the prompt only needs the motion, the camera and the sound.

Same price as text to video

On the Grok video generator, image to video costs 2 credits per second at 480p and 4 at 720p, sound included — the same as text to video. An 8-second 720p clip from a photo is 32 credits.

Write the sound in

The Grok video generator always renders audio, so tell it what to hear: rain on a window, a crowd cheering, a kettle starting to whistle. Two or three sound words are enough; leave them out and you get generic ambience.

When to switch models

For 1080p or 4K, or takes with tighter control, use Kling 3.0 — 14 credits per second at 720p with audio on. For silent drafts, Kling 2.5 Turbo is 6 credits per second. All three run on the same balance.

FAQ

Grok video generator FAQ

Still curious? Email support@picturetovideo.org — a human replies within a day.

01What is Grok Imagine?

Grok Imagine is xAI’s image and video generator. Its video model — what people search for as “Grok Imagine video” or simply the Grok video generator — turns a text prompt or a photo into a short clip with sound generated alongside the picture, at some of the lowest per-second prices of any video model.

02Can I use the Grok video generator here today?

Yes. Grok Imagine runs in the generator on this page as the Quick tier: text or image to video, 5, 8, 10 or 15 seconds, 480p or 720p, with sound. You need a PictureToVideo account and credits — no X or Grok account.

03How does Grok image to video work?

Switch the generator to Image, upload a photo and describe the motion and the sound; the Grok video generator animates the scene and adds audio to match. It costs the same as text to video: 2 credits per second at 480p and 4 at 720p.

04How much does the Grok video generator cost here?

2 credits per second at 480p and 4 at 720p, sound included. The shortest clip — 5 seconds at 480p — is 10 credits; an 8-second 720p clip is 32 credits (≈ $0.43 on the Pro plan), and the longest, 15 seconds at 720p, is 60.

05Is Grok Imagine free here?

No. There is no free tier on PictureToVideo; the Grok video generator is paid per second like every other model. The cheapest way in is the $2.99 starter pack — 200 credits, about 6 8-second 720p Grok Imagine clips with sound.

06Does the Grok video generator make sound?

Yes. It generates audio with the picture on every clip — sound effects and ambience to match the scene — and the sound is included in the rate. For sound at 1080p or above, use Kling 3.0 with audio on (14 credits per second at 720p) or Veo 3.1 Fast (21 credits per second, 168 for an 8-second clip).

480p or 720p, in 5, 8, 10 or 15-second clips, in 16:9, 9:16, 1:1. It does not render 1080p; for a sharper delivery file, re-run the keeper on Kling 3.0 or Veo 3.1 Fast with the same prompt.

08Is this xAI’s official Grok AI video generator?

No. PictureToVideo is an independent studio that calls Grok Imagine through an API provider, next to Kling, Veo, Wan and Hailuo models on one credit balance. We are not affiliated with or endorsed by xAI, and you don’t need an X or Grok account here.
