What Grok Imagine Video 1.5 does well

01

A first frame that holds

The still you start from stays itself, same markings, same blanket, same lamp on the glass, while the rain runs and the tail curls. The purr and the rain arrive with the clip, not from a sound library afterwards.

Prompt

The cat blinks slowly, one ear flicks toward the glass and its tail curls once around its paws while rain keeps running down the window and the lamp light wavers. Very slow dolly in, ending on a soft close up of the face. Sound: steady rain on the window, a low contented purr, one car passing on a wet street far away, no music. Keep the cat's markings, the blanket and the room exactly as in the source frame.

02

She says the line herself

A potter looks up from the wheel and delivers one line straight to camera, with her mouth matching the words. The voice, the wheel hum and the room tone come out of the same pass, so nothing has to be dubbed on later.

Prompt

A woman in her early thirties looks up from a potter's wheel in a sunlit studio, wipes one wet hand on her apron, smiles at the camera and says: "Careful, it is still wet." Clay dust hangs in the sunbeam behind her, a shelf of drying bowls sits out of focus. Slow push in from a medium shot to a close up, warm window light from the left. Sound: her voice close and natural with accurate lip sync, the low hum of the wheel, a faint scrape of a tool on the bench, quiet room tone, no music.

03

Your product, their location

A shoe from one picture lands on the coping of a skate bowl from another, colour, gum sole and scuffed toe intact. One pass gives you the orbit and the wind with it, with no second shoot to book.

Prompt

Use <IMAGE_0> for the shoe and <IMAGE_1> for the location. The sneaker from <IMAGE_0> rests on the chipped coping of the empty skate bowl from <IMAGE_1>, unchanged in colour, gum sole and scuffed toe. The camera orbits slowly around it from a low angle as the last golden light sweeps across the concrete and a light breeze lifts dust off the bowl, ending with the far wall soft behind it. Sound: wind across open concrete, distant traffic, a loose chain link ticking against the fence, no music.

The technology behind Grok Imagine Video 1.5

How the model works, based on public documentation and sourced evidence.

Grok Imagine is xAI's image and video line. On the video side, Imagine Video 1.5 went to preview on May 30, 2026 and reached the API on June 16, 2026. It builds a clip from a text prompt, animates a still image, or works from reference pictures that the prompt points at one by one. On release it took first place on the Image to Video Arena, 52 Elo above the version it replaced and ahead of Seedance 2.0, HappyHorse 1.0 and Veo.

Sound effects, ambience and dialogue are produced in the same pass as the picture, so the audio comes back already in step with the frames instead of being laid on afterwards. A Fast variant returns a six second 720p clip in about 25 seconds, against 40 seconds or more for the previous iteration. Official API list price is $0.080 for each second of video.

On Vidney the video side is Video 1.5, and audio comes with every run: dialogue, sound effects and room tone, generated with the picture and with no switch to turn it off. Text to video, image to video from a first frame and reference generation with up to seven images are all open, and clip length is any whole number of seconds from 1 to 15. Text to video and image to video run at 480p, 720p or 1080p; reference generation stops at 720p, because the API accepts only one input picture once you ask for 1080p. Last frame, reference video, extension and editing are not open here.

Who uses Grok Imagine Video 1.5, and what for

Grok Imagine Video 1.5 fits anyone who needs videos fast without a production crew or a freelancer budget. Performance marketers use it to batch ad creative: a DTC team spins up a dozen hook variations for a single TikTok campaign and A/B tests them the same afternoon. Social media managers turn one content calendar into a week of Reels and Shorts without booking a videographer. E-commerce sellers generate product demos and lifestyle shots for Amazon, Etsy, and Shopify listings, refreshing creative as fast as inventory turns over. UGC creators and affiliates mock up native-looking spots for brand deals before committing to a shoot. Indie filmmakers and game studios pre-visualize scenes, testing framing, lighting, and pacing, to lock a direction before spending real money on production. On Vidney you run Grok Imagine Video 1.5 next to every other major model, so you choose the best one per project instead of locking into a single provider.

What creators say about Grok Imagine Video 1.5

Recurring themes from public reviews, comparisons and creator write-ups. Both the good and the bad.

What gets praised

  • Speed is what keeps the video side in use: the Fast variant returns a six second 720p clip in about 25 seconds, where the previous iteration took 40 seconds or more, so a joke or a reaction cut gets reworked rather than queued and abandoned.

  • Price keeps it in the rotation. The official API list price is $0.080 for each second of video, cheap enough to run a dozen takes of a reaction cut and keep the best one rather than agonising over a single expensive render.

Common complaints

  • The cost model punishes mistakes. xAI's pricing page states that when a request is deemed to violate its usage guidelines, the generation is still charged, and violations caught before generation in the Responses API carry a further $0.05 fee per request on top of that.

  • Safety around real people is the standing risk. NBC News reported on April 14, 2026 that eight law enforcement and regulatory bodies were still investigating Grok's nudification and sexualization capabilities, after The Verge found Spicy mode making topless deepfakes of a pop star unprompted, and found users working around the January block.

  • Ceilings arrive early. 1080p is tied to a single input picture, so a clip assembled from several reference images stops at 720p.
