Capabilities

What's new in Grok Imagine Video 1.5.

xAI's best motion yet

Version 1.5 is a step change over the original Grok Imagine Video on motion quality, physics, and temporal consistency, holding subjects steady through fast action and complex camera moves.

Built for image-to-video

It takes one source image as the opening frame and animates from there, so identity, styling, lighting, and brand colors survive the whole clip instead of drifting.

Synchronized audio in one pass

Music, sound effects, and ambience are generated alongside the frames, so you get a finished clip rather than a silent render waiting on an audio step.

Up to 15 seconds at 720p

Pick 6, 10, or 15 seconds per request. Leave the aspect ratio on auto to inherit your source image, or force any of the seven supported ratios for a specific placement.

Priced by the second, billed in credits

A 6-second clip is 144 credits, 10 seconds is 240, and 15 seconds is 360, no xAI subscription, minimum spend, or separate invoice.

Same API as every other model

One endpoint, one key, one bill. Swap the model id to move between Grok Imagine Video 1.5, Veo, Kling, Sora, and the rest of the catalog without touching your integration.

Use cases

What teams build with Grok Imagine Video 1.5.

Animate any still

Feed one image and a motion prompt, Grok Imagine 1.5 turns portraits, renders, and product shots into moving clips with believable physics.

Every placement, one prompt

Eight aspect ratios from 16:9 down to 2:3 (plus auto) mean the same shot ships to feed, story, and banner without re-generating.

Character performance

Improved motion coherence over Grok 1.0 keeps faces and limbs stable through gestures, walk cycles, and camera moves.

Flat-priced clips

Per-clip pricing at 6, 10, or 15 seconds keeps unit economics predictable for batch campaign work.

Seamless experience, excellent support

Just created 6 videos and the experience has been seamless. Wanted to write a review for appreciation — the customer support has also been excellent. They helped me in some process I was stuck in.

Stable, easy image & video generation

I like that I can generate images and videos without complicated setup. It works stable and is easy to use even if you are not a big developer. It saves me time and makes the whole process much simpler.

Grok Imagine Video 1.5 questions

What teams ask before shipping with Grok Imagine Video 1.5. Everything else lives in the docs.

What is Grok Imagine Video 1.5?

xAI's newest Grok Imagine video model, built on the Aurora engine. It animates a source image into video with better motion, physics, and temporal consistency than the original Grok Imagine Video.

How is it different from Grok Imagine Video?

Version 1.5 is image-to-video only and costs more per second, but delivers noticeably better motion and physics. The original model still handles text-only prompts and multi-image reference sets, and is cheaper for drafts.

Does it need a source image?

Yes. Every request takes an image URL alongside the prompt, the image becomes the opening frame and, unless you override the aspect ratio, sets the output shape.

How long are the clips and what resolution?

Choose 6, 10, or 15 seconds. Output is 720p.

Does it generate audio?

Yes. Synchronized audio, music, sound effects, and ambience, is produced in the same pass as the video.

What does it cost?

144 credits for 6 seconds, 240 for 10 seconds, and 360 for 15 seconds, drawn from the same balance as every other Apiframe model.
